Volvo :: Engine Won't Start When Driven A While
Jul 3, 2007
So I've got the problem where the engine won't start when it's been driven a while. The engine cranks and starts, but the RPM retards/drops until it reaches 0 after about a second or two.
I've measured voltage to and from the fuel pump relay. It gets 12 volts and spits out 7.5 volts with ignition on and engine not running. This is the correct voltage, so I see no reason to suspect the relay being the culprit. Besides; I can feel the relay clicking and hear the fuel pump working when the problem occurs, meaning that they both should be working fine. That's the conclusion I've reached, let me know if you think I should investigate the relay more thoroughly.
This has led me to start thinking that the ECU is getting some bad input from one of the sensors monitoring the conditions of the engine, resulting in an incorrect fuel mixture.
The first sensor I checked was the coolant temperature sensor, which turned out to be quite correct - a couple of % lower than what the table says it should be. Could this have any effect?
What other sensors are sending important signals to the ECU, possibly contributing to bad fuel mixture? Air Mass? Air Flow? Oxygen Sensor? Are there any vaccuum hoses or idle valve components that could cause this behaviour?

My 1999 Civic, manual trans, 127k, 1.6 4 cyl, has problems starting if the car has been sitting for more than 1 hour. For example, if I go to store for 5 min and start the car, it starts up instantly. Car drives fine and when I "Floor it" Peddle to the floor, i have all the power there. Its just when i start the car after 1 hour of sitting, or over night, it takes a good 5-10 seconds of cranking to start. What could be wrong?

This issue has been stumping the mechanics. My wife's HHR has 113,000 miles on it and has been trouble free up to now. The last two months it will suddenly not want to start after being driven for 20 - 30 minutes and then sitting for an hour to 75 minutes. It turns over but won't start. Even more strange if you then wait for a full hour it will start right up. Mechanics are stumped as they cannot duplicate the problem.

My wife has a 2002 Volvo S60 that we share with ~165,000 miles on it now. In the last 4-5 years or so, it developed this problem of feeling like the whole engine is shaking when we start it up sometimes. It can go days or even a week where we don't have this problem and then all of a sudden it happens one morning or afternoon, or whenever without any rhyme or reason. While it's shaking, the lights on the dash go in and out with the shaking (going between dim and bright). What also happens right before the shaking sometimes is that the engine will rev itself, like its got a mind of its own, sometimes up to 2000 RPMs, like I am pressing on the gas pedal and holding it, but I'm not! It will stay revved up for a good 10 secs or so then come down on its own and proceed to shake. We usually turn the car off, then on again and it goes away. If it doesn't go away, then we repeat (off/on).
We've taken it to the dealer multiple times, including in different cities since we happened to move in the last few years to another city and still, no one can solve the issue. She swears it all started happening after we went a week without the gas tank lid after it got left off by accident after we pumped gas one time. I noticed it was missing definitely within < 7 days and got a replacement right away from the auto store. Not sure if that has anything to do with it?
The car otherwise still runs fine but we just never know when the shaking thing is gonna happen next. It can even happen on the highway when we are driving. You can be trucking along at 70 MPH or so and then ease up on the gas and we'll feel it in the gas pedal and the car...it will jolt and shake a little until we rev the engine above whatever speed we had decelerated to when the shaking started.
When the shaking has happened, I have gotten out of the car to examine under the hood and cannot see anything in particular, the whole thing is just moving like normal and shaking a bit and then eventually if you leave it long enough, it stops on its own.

I have a 95 Volvo 850 2.2 L (non-turbo.) I recently replaced the fuel pump, and filter. Now when I try to start the engine, it turns over and sputters before it dies. I let it sit for about 10 minutes and try again with the same results and the same with a longer wait time due to having to charge my battery. I have checked the fuel lines and they seem to be clear, up to the fuel rail. I also checked the plugs and although they need to be replaced, after sanding and re-gaping them, there is plenty of spark. The plug wires and distributor cap are fairly new, and the points look good. So the only problem I see as logical, is the fuel rail, pressure regulator, and injectors. I have bled the fuel rail at the shrader valve, and I am getting little to no fuel from it. I want to remove the injectors and rail, and check out the regulator along with the rest. But how do I tell if the regulator is good, and what is the best way to clean injectors so they will at least last till I can replace them with new?

I have a 2003 Camry 4cylinder. On first start of the day the engine shakes a little untill it warms up and is driven for about 2 blocks. After that it is smooth. I cleaned what I could of the throttle body on the car, changed spark plugs and PCV. All that worked but cold start shake still there.

This has happened 3 times now in the last couple of months. After driving on wet roads, our 2003 Mazda3 won't start. It won't even crank or turnover (primary vs. secondary ignition). All of the other electronics come on when you turn the key, but nothing from under the hood. After a while of presumably drying out... anywhere from 15 minutes to hours, it starts again. I'm thinking something is shorting, but what.
Mechanic can't figure it out... but he's only had it for a day, and it's been dry, and starting fine.

I have a 97 Volvo 850. A couple weeks ago, it stalled a half dozen times while starting. The engine would turn over, start, run for a few seconds, then stall. Before calling for a tow truck, I started it up again, and it ran. After idling for a few minutes, it appeared to run smoothly. We drove home without a problem. When I took it into the shop, of course it wasn't acting up. A little later, the technician called to say it acting up for him so he knew I wasn't going crazy. He took it back to the shop, and it acted up again for another tech. They have since put their instruments on the car but it refuses to tell them anything. The check engine light works. All pressures are to spec. The fuel filter has been checked as well as all fuel lines. The car has not acted up now for over a week. The shop still can't find the problem.

When I start engine usually your dashboard light turn on, eng, seatbelts, etc. but that doesn't happens, but engines starts for awhile and than you see the volt indicator drawing negative. And after few minutes of running it dies and will not start, battery is dead, I believe there is a short circuit or a relay problem....

For the 3rd time this winter I have been unable to start my SUBARU IMPREZA because of Dead battery. Usually it is after I have not driven for 3 - 5 days. Each time it is jump started (AAA) and I have driven it to the local Subaru Service Center. They have tested and analyzed battery and charging system and find nothing wrong!!! (Battery was replaced last March). They say drain measured very low (3mA?).
One ?clue: when jumper cables are hooked and powered up to start car, you can hear the CD changer trying to find a CD or something. But there are no CDs and we never leave it on. I mention this to the Service manager and he says that the measured battery drain is too low for that to be the problem.

I have a 1995 volvo 850 t5. Basically, the engine is making a clicking sound. Immediately on start up, which continues when i drive. In saying that, I've been only doing 5 minute drives so perhaps its not running long enough to go away.
So today, i started it. Car starts ticking. The ticking is like 3 or 4 seconds apart between clicks, and the idle seems to change slightly each time it clicks.
I checked the oil and it was a little low. So i put 2 litres in, and then i ran the car (idling) to see if it would go away. Just for a few minutes. It did seem to go away, but then i gave it a little rev and it came back.
So in summary, clicks on start, idle and while driving. Idle changes slightly between clicks. And there is a few seconds between clicks.
Just checked it again. If i leave it idling the click stops but as soon as there are more revs, it comes back. And the noise is almost like the click of a switch (like when your kettle finishes boiling and the switch flicks off. Not the best comparison but similar).

I have an '89 740 wagon, Bosch ignition. It will not start. If I spray starter fluid, it will fire, then immediately die. I have replaced already both fuel pumps, noise suppressor/fuel injector relay, fuel pump relays.
I installed a fuse in the fuse box, which was empty when I purchased the car. And the engine instantly died. It did start up when the fuse was removed, and I drove it back across country. The idle got worse until it died and would not start back home.

A minor but persistent (year-long) rough idle on my 1991 240 has quickly turned into a Cold Start Nightmare over the past month:
SITTING HOURS OVERNIGHT (50 to 60-degree temp. overnight) - When I attempt to start in the morning, the engine idles high for 3-5 seconds and then immediately dies. To successfully start, I must keep pressing the accelerator pedal at least half-way down for 2-3 minutes. The engine sputters, almost backfires, shakes, lopes, almost dies, etc. After 2-3 minutes, everything runs just fine.
WARM ENGINE SITTING - Once the engine is warmed up, it will consistently start without problems. Still a slightly rough idle, but OK. The car does not die.
I have changed the battery, coolant temp. sensor, and spark plug wires.

I have a 2003 Super Duty 6.0. The trouble started almost all at once. It started fine, then I drove it for a while and on hot start, it cranked for a long time before starting. This went on for a few days, then today it wouldn't restart even when cool after not being driven for hours. I have a code P2285 and code P2285 P that has been on for a month or so. I know that the P2285 is the ICP. I don't know and can't find out what the "P" is at the end of the code. Anyways, I want to repair it myself. I have experience doing pretty major repairs, so it doesn't scare me. The problem is I am new to the diesel world. So come one and come all with possible scenarios and I will Go right down the list.

I have a 1994 Ford F-150 pickup with a 4.9 litre fuel injected inline six. Truck ran fine and took me to my destination but after sitting for 4 hours the truck would not start. Engine would turn over normally and could hear fuel pump running (didn't seem to stop) but truck would not start.
I changed fuel filter but truck would still not start. I removed air filter assembly and poured starting fluid in the air intake and engine started but idled roughly. Engine will rev up but runs very rough and lacks power when driven. Also the check engine light stays on.

03 focus SE Wagon, Automatic Tran, has a bit of a problem. Whenever it gets driven through a puddle (big, small, paddling pool, etc.) it will make this high pitch squealing noise, and then when it gets shut off after driving through said puddle, will have trouble starting. (It will turn over, catch, run for .2 seconds & then the engine will cut out, but all the electronics will work) THEN! if you can get it started, it needs to be reeved constantly or it will stall when it idles. Lastly, if the conditions are ridiculously horrible, & you need to go some place, you have to '2 foot drive' the little beauty to whereever you're going. Now, she's been in to see the Ford mechanics and has 'stumped' them.

I have a beautiful 1987 560SL. My husband and I bought it about 17 years ago and lovingly refer to her as our mid-life crisis car. Truth be told, we're a bit past "mid" life now and have decided to sell it and let someone else enjoy her. Last summer she started to have an annoying issue and we "thought" it was fixed, but right after I started advertising, she started acting up again.The engine simply dies while driving. It always seems to happen when I've only driven about 5 miles and going rather slow - 20 to 30 mph. She'll start back up after a try or 2 and be fine. We took her to a local shop and the mechanic said one fuel pump was shot and the other was not working properly so we replaced both and all seemed fine the rest of the summer. We garage her for the winter as we live in the Rockies and she's not the most practical car to be driving in the snow and ice. This summer she started right up and was doing well until a few weeks ago - same problem.

I have a 95-960 [straight 6] that doesn't want to start!
I parked the car roughly 8 weeks ago, yesterday I went to start it! ..firstly the battery had gone flat, No big problem, the battery is only about 6months old so I whipped out the car starter battery pack thingy [as I Have done in the past after a long time parked] but to my dismay it didn't kick! firstly i was concerned that the fuel pump may have *** it's self, so I cracked the fuel line at the engine and turned the ignition on!..plenty of fuel!Next I take one of the coil packs out and turn it over again...NO SPARK!..I only just parked it here a couple of month ago and it was fine..
the car normally runs faultlessly and has never not started in the past, it has all new timing belt and tensioner fitted a couple of thousand k's ago, new battery, plenty of fuel, and less than 200,000kms on the clock..

I recently purchased a 1991 Volvo Turbo 740 with 186,000 miles on it. It runs perfect for a few days and then when parked will not start. Attempt to start 1/2 hour later it starts and runs perfect again. It has done that for several days now. I have driven it to locations approximately 40 miles round trip with frequent stops for a period of time and then start up again. This AM it started up perfect as I moved it from a driveway to part in front of my house on the street. Several hours later I went to start it but it would not start. 1/2 hour later I decided to try one more time before calling the tow truck to take to a mechanics and it started up perfect again. I drove it to the library and bank later and ran perfect after the two stops. This is driving me nuts since I had taken it to a mechanic when it did this Monday and it ran great at the mechanics and he could not determine what was wrong. He told me WHEN it stops again to have it towed in and he could determine at that time when it was not running.
