Volvo :: 1990 - Long Crank Then Eventually Start But Run Real Rough
Jan 3, 2012
1990 Volvo 760 4 cyl. Turbo. Drove the car to work, everything fine. Got off work, car wouldn't start. Cranked but wouldn't start. It was getting spark. Changed the fuel filter, it ran perfect for a month. Drove it to town a month later, shut it off, then trying to start it, would crank and crank eventually start but run real rough. We got it home....barely.
Replaced the fuel filter again. Still wouldn't run right.
Replaced the fuel pressure regulator. Same problem.
Replaced the throttle positioning switch. Same problem. Replaced the air control valve. same problem.
Found out that this car has an on board diagnostic doo hickey.
Found out how to check each sensor and component individually.
All sensors and components are working. Checked both fuel pumps and they are working. If I unplug the air flow sensor and the air control valve sensor, I can start the car using starter fluid and it will idle all day with out missing a lick.If I plug in either one of the sensors, it will kill it immediately.I don’t know what else to do to make this machine run.

When I start my S60, it runs extremely rough and will eventually stall. I do this over and over . . try and put it in gear and it will go a bit, run very rough, and will stall out. After a few minutes, something kicks in and it runs perfectly. If I don't try to drive, and sit with it idling, it runs very rough and I have a difficult time getting the rpms up. Then, the engine will suddenly race for a bit and everything is fine. It is very periodic in nature, doesn't matter if the engine is cold or not. It can sit over night and be fine, or do it, I can run around all day without problems and then suddenly it decides not to start up and run. The temperature outside doesn't seem to be a factor.

On the way to work, the truck seemed to have a miss at idle and the CE light came on. Long crank to start leaving work, and truck starts losing power and eventually died. No smoke while it was losing power. Towed it home and checked the fuel pump and lines for blockage and found nothing.
2003 7.3 F-250 430K miles
strong cranking but no start no smoke out exhaust
Oil changed recently
IPR changed
Both UVCH gaskets and pigtails have been repaired.
ICP sensor and harness changed, also disconnected no change in cranking.
fuel filter changed today (no oil in bowl)
3/4 tank of fuel
dash gauge for lpop goes up to normal range during cranking and oil light turns off.
WTS light comes on and turns off as normal
tach gauge moves up between 100-200 during cranking
fuel pump turns on and pressurizes system like normal and turns off.
Ordered AE for the truck, and it directed me to the passenger side bank high open. Fixed the harness on that side and still nothing.
Sent off the IDM and it passed with flying colors
So now i'm leaning towards the HPOP, but would hate to fork over the cash for it and still not get anywhere. I'm going to take the valve covers back off and check the discharge ports for the injectors tomorrow.

Will try to sum it up: Most of the time, the thing starts like a charm, first try. Every now and then, though, I'll turn the key and either a) nothing will happen or b) it will slowly crank and eventually start. If nothing happens, I have always been able to try again seconds later and everything works OK. Have been through several batteries. Current battery checks out OK, as does starter and alternator.
A short circuit, perhaps? If so, how would I check it out? Problem with taking it to a mechanic is, most of the time all is OK. No pattern as to when the trouble will occur (has yet to happen with vehicle in the shop, of course).

My 99 250, 7.3 is having some strange issues as of lately. When I start it in the morning, when the engine has fully cooled down, it starts right up, then it throws the "wait to start light" runs real rough and just shuts off. Run the glow plugs a few times, start it up and it will do the same thing for maximum 30 minutes, then all the sudden I start it and it runs fine. I've replaced the fuel pump, cleaned the fuel bowl, new fuel filter, I just don't know where my problem could be. It doesn't make sense. But once I get it running and it warms up, runs fine all day. Go to bed, wake up, has problems again.

I've got a 90 240 DL that stopped dead and won't restart. Hit it with starter fluid and it fires off, but stops. Had no way of testing fuel pressure, so replaced in-line pump. Tank pump runs, can hear it through filler opening. Problem persists, even with new pump and filter. Pulled vac line to FPR but no gas leaks there. Also, new plugs, distributor cap and rotor, new air filter. Pulled MAF sensor plug, still no start. Checked FP relay (also spare) and jumped FP relay to test. No go. Where do I go now? Should I check computer codes? Replace FP regulator, crank sensor? Everything? Can the on-board computer be bad?
Trying to find a path to go on since the new pump seems to give plenty of pressure.

My 1990 740 will not start. These are the tests I have completed:
Starter and battery are in good condition.
The fuel pump works, it delivers fuel pressure on initial starting.
The plugs are new and gaped correctly.
I am getting a good spark at all plugs.
I have tested for power at the cold start valve. It is connected to the top of the starter and is at 9 volts while starting the engine.
The timing belt is new and is operating correctly. The engine is timed correctly.
I have noticed that there is no fuel getting to the plugs. I pulled one and it is dry.
The code is 3-2-1. Cold Start valve? It is 75 degrees.....the car should start?

I own a 1990 Volvo 740 GL. It cut off at a stop light one day and now it will not start. It seems to be a fuel related issue, if I squirt staring fluid into the intake it will start but cuts off immediately. I removed the fuel line that connects to the injectors and no fuel is coming out. I checked both the number 1 and 11 fuses both are fine. I have replaced the fuel filter, fuel pump, and the fuel pump relay.

My 06 currently has 296k miles. 3 years ago I put a lot into her. Dummy plugs, stand pipes, STC, hg,studs, oil cooler, bpd egr cooler. Cleaned spool valves and fresh o rings in injectors. (Alliant) plus a lot more that I can't remember. Ran very very well after all that.
Fast forward to a few weeks ago. Driving down road and truck died as I let off pedal to slow down for turn onto my road. Took about 7-8 tries to get started back up. Icp was reading in the 300's until it finally started. Made it home. Shut it off. And started right back up.
Few days later truck died again same way. Let off to make a turn. Several attempts to restart icp was in the 300's again. Once it started building 420ish it sounded like it was firing a few injectors and slowly started running. The next time it happened the same way but when I got it back running I eased to my inlaws like less than a mile. When I got to their house and pulled in and went to back up to turn around the display on dash said low oil pressure and started missing a little. So once I got home started researching.
A few days ago I pulled out the low pressure oil regulator to check it out. It was clean but did have some mild scaring. I used some fine scotch rite and smooth it out a a little. It moved freely in the bore so I put it back together. Then pulled the oil filter cap off to check the little black valve. I noticed the filter was not dripping with oil like normally when I change the oil. And yes it's motor craft filter and cap. It checked out ok. Press it down and turned engine over and it filled and held. Let off of it and it drained.
Next I air checked the high pressure side. Applied air and waited until I could hear the air (IPR still open) then closed the IPR. Couldn't hear any leaks. Just a very very minor his and couldn't pin point where. So I went ahead and went to dealer and got new stand pipes and plugs. And ordered new print set for injectors. Pulled injectors and didn't see any smoking guns. Replaced prongs, stand pipe and dummy plugs and put it all back together. Cleaned the injector cups and hold down bolt holes. Torqued injectors to spec.
Got it all done and rotate motor by wire next to heater blower to assist prime system. Tried to start it up and it took two tries but fired right up and sounded smooth as hell. After it idled a few minutes I saw a haze from exhaust. It smelt just like fuel. A few minutes later started idle a little rough. Gave it some go pedel and it was rougher at about 1600-1800rpms and couldn't feel it above 2k. Got my laptop out with AE and done balance test. Did not show anything. No codes either.

Recently replaced alternator on Volvo 240 dl (covered under warranty). Battery checked numerous times and comes back as working perfectly fine. For some reason the battery is not taking a charge from the alternator or something is draining the battery too fast for the alternator to charge the battery. Regardless, after driving the car to and from the car either will not start (but jump starts instantly).
Upon the car breaking down yet again today and attempting to drive it home the car lost all power and shut down while driving down the road. The first noticeable thing was the gas gauge dropping slowly from 3/4 to empty and then all power loss. Upon hooking jumper cables up and 'charging' by another vehicle the Volvo would again drive for a short period of time before the same thing happened.

I have about 3400 miles on my Sonata 2.0T, and I have experienced a long crank with (puttering in between), and does not start, twice occurrence thus far. I have no warning lights, no lamps (SES) that stay on afterward, nothing at all. I have had to press the "start/stop" button again to make it stop, then let it sit for a few seconds press the button again, re-cranks, and starts this time. I know that if take to the dealer they will not find anything wrong since most concerns they have to duplicate in order to diagnose. The SES light is not on, so I know we have no fault codes to go by. Sounds as if the fuel pump is crapping out, or no spark is being generated.

Installed a "new" battery in my celica (it was used but tested good) went to start up the car to see if it was good and the car started right up
Shut the car off cleaned up my throttle body a bit the went to start the car again it it would just crank and crank
I just put in a new fuel pump, so that cant be it, I have not checked for spark yet ( car is stuck at work )
I heard that the ignition coil likes to fail on these would that be causing this problem?

I left my F150 to sit over the winter parked near my house. Battery was bad when I went to start it a few weeks ago. Got a new battery, threw it in, but still no start. It wouldn't crank.
Went to work on it today and the battery was totally dead, took it to schucks and they said it was bad. So I got it replaced with a fresh one and I'm still getting the same thing.
Turn the key on and accessories come on, turn it all the way and nothing happens, except for the aftermarket radio turns off. I replaced the ignition switch last year. I tore apart the dash to see if that went out again but it looks fine.
What should my next step be?

My grandma has a '07 XLE 4cyl with around 65K on it.
Every once and awhile, completely intermittent, no consistency whatsoever it takes 4 seconds or so to get the car to actually start. Normally 1-2 seconds.
Was going to change plugs. See that you have to replace the whole pump/strainer assy. in the tank, no stand-alone filter.
No DTC's or any other lights on. Wondering about replacing the whole pump/strainer assy. will fix it or what the deal is. Can't order it online at Advance Auto parts, and called their store and the Denso one they show isn't even listed as available at the factory. Hope you don't need an OEM one, sure that's not cheap.

I own a really nice original ' 89 Chrysler Lebaron coupe with the 2.5 N/A, throttle body injection and 3 speed automatic. It has just over 100k miles. The car sits in the garage all the time and is not used during the winter months and is never used in the salt season. I do "try" to start it sometimes just to keep the battery up. The problem is when I want to start it, especially after sitting for a while, often it will crank and crank but won't start. It's acting like it has no gas. When I take the aircleaner lid off and dump a little gas in, it fires up just fine then runs perfect after that. Even after it has been used as a daily car after that, when I shut it off, sometimes it will start just fine, other times it won't, then I have to use the gas can again. It has a mind of it's own. When you think it will restart, sometimes it won't. I've been keeping a little gas can in the trunk in case it does happen at odd times. With the gas can, it will always restart. I've talked to a few shops about this, they have no idea what might do this. Naturally, when I brought it in to show it to them, it would ALWAYS restart for them. Getting rid of this car is not an option for me, I love the car, except for that part of it.

My '90 240 will not start. When I turn the key to Acc. or Start I hear a whirring sound coming from the fuel pressure regulator so I assume the fuel pump is not an issue. The engine will not even crank. I assume it is the ignition coil or the starter but I am unsure. As an FYI, the battery and plugs are good.

So my 2002 ford explorer with the 4.0 L V6, has been cranking along time before it starts. I thought i had this figured out already, i put a brand new fuel pump in it from the ford dealer. That seemed to work, but the problem came back.
Especially when it is cold, it cranks a lot longer than normal to start. and when it does start RMPS go way up briefly and come back down. Seems to only act up when its cold out, say 35 degrees and lower.
So the remote start wont work because it only cranks for a few seconds and then stops. it tries this three times and it gives up. i go out there to start it and cranks for 10 seconds it seems like, sometimes i have to feather the fuel pedal.

My problem is on my gf's 99 Passat. Its the 1.8t and runs and drives fine. The abs/brake light is blinking which from reading seems common and I have to send that module out to be rebuilt. The issue I am having right now is every once and a while it wont start. It will crank and crank and finally start like a minute later. She's convinced pumping the gas pedal works but I don't think its fuel related at all as it smells flooded when it finally starts. Ive replaced the plugs, air filter and still does same thing.

Car does not have to get wet, just be in humid air. Problem going on 2 years now, mechanics tried disconnecting a (?) ground/sensor from computer, major tune up, new fuel pump. Until recently, it just took keeping it in crank position for a long time for it to finally start. Recently, in crank position for 30 seconds does nothing and has me worried I'm doing damage. In dry weather, it starts first time every time.

I have a early 99 f250 super duty 7.3l and it's giving me fits. about a month ago the truck started to do a hot no start. drove truck for about a hour. Shut it off and half hour later no start. Let it sit over night and would start with long crank.
Changed CPS no change. Pulled tuner and set back to stock. No change.
Changed fuel filter, no change.
After reading forums changed IPR and truck started and ran great. About a week ago back to the same problem. Battery's are about 2 months old. Oil change and oil filter a month ago.
Checked the hpop reservoir and its 1/2 from the top.
Checked fuel bowl and it has fuel. no sign of oil in it.
Drained bowl and watch bowl fill back up. seems to fill quickly.
Pulled passside valve cover to check for bad orings while cranking.
Every thing seems fine. have not done driver side yet. used FORSCAN and ran buzzed test on injectors and they all buzzed what seems to be about the same. ran test couple of times to make sure. this morning I ran a live scan while cranking and this is what I got right before it started. ICP 660.6psi, IPR 64.84% and RPMs 227. took 8.86 seconds to start. after work scaned again for hot no start and this what I got. ICP 292.9psi, IPR 55.86%. and RPMS 203. unplug ICP and no change. still will not start. one thing I did notice when plugging ICP back in I looked down in side at the pins and can see what seems to be bubbling around one of the pins. the pig tail has just the slights sign of oil.
