i have a 2001 f250 7.3L PSD. it turns over but will not run. replaced the CPS , starter and the #30 fuse. IPR is new and all injectors are new, new gaskets and harness and new glow plugs new batteries. still just cranks and cranks. no oil pressure build up and no tach movement, oil level is good in HPOP. What could it be?
View 14 RepliesI've replaced the alternator and starter recently and both batteries and the truck ran fine befor that. But it sat for roughly 2 months and now it seems as if its not getting fuel. Will start with a shot of ether but will die as soon at it burns it off
View 14 RepliesI purchased this unit, non running, was told the HPOP was bad, after going through the unit top to bottom, Im stumped, below is a list of items serviced and or replaced with OEM parts.
0. changed oil and oil filter
1. Terminator 500 Hpop
2. New ICP
3. New HPOP lines.
4. New starter and solenoid
5. Serviced Turbo (rebuilt with new parts and WW wheel)
6. Serviced Injectors (shimmed) all test good.
7. new pass and driver harness, UVHC replaced, glow plugs replaced.
8. new heavy duty GPR
9. Tested IDM no issues.
10. Hutch mod on tank (re-circulator was stopped up) deleted it, added inline filter.
11. serviced fuel bowl with new parts, upgraded parts on fuel bowl new blow off valve, new drain valve, tested heater all good no blown fuses.
12 replaced faulty fuel pump
Might be leaving something out of this list, the truck has run but only for very short periods of time, (hence the dropping of the fuel tank)
fuel pressure at 70 psi, some white smoke, connected to on board computer, checked every conceivable possibility No DTC codes, my gut tells me it has to be fuel related but at this point I just have run out of things to check.
I have tested everything with a fluke multimeter, including the IDM and all the circuits to the 42 as well as all the way to the injectors and glow plugs and find nothing wrong all tests yield valid readings,
There may be other information available but my after market scanner does not show any issue, KOEO buzz test results good.
The three times I have had this unit running it was dumping lots of white smoke, however after the last round of dropping the fuel tank and replacing the fuel pump the white smoke has dropped to a minimum, but cannot get the truck to run, cranks, wants to start, almost starts, got it up to 800 RPM last try but just will not go beyond that point.
I cannot find anything wrong, must be something I am either missing or its something my cheap scanner can't pick up on.
I have a 2001 Excursion 7.3 Diesel that is having a starting issue. Have replaced the batteries, has new glow plugs, common failing cam position sensor replaced once already. It runs great when it starts, no codes. It will crank, but not turn over at random times. Will do this for 3 or 4 tries...charge the batteries, go back later to start and it will on the second try. Turn it off, try again..and back to cranking, but not starting. Not fun having to worry about being stranded somewhere. Absolutely desperate at this point.
View 4 RepliesI went on deployment and handed the wife to crank the truck up she did but didn't drive it so batteries didn't charge back up. I got them charged up and the truck cranked right up. I was plugging it in at night and it would start just fine the next morning. Then a week later batteries kept dying in a few hours during the day. Had to jump it again. then even when plugged in trying to crank it there was a buzzing noise and it would crank but not start. I bought new batteries and it cranked right up and drove fine until I shut it off and same problem and batteries were low again and it will crank but wont turn over. I am thinking maybe alternator.
View 3 RepliesI just started having an issue on my 01 7.3 f350 with 203k miles, it will crank much longer then normal to start. If you shut it off then try to restart right away it starts normal, if you wait 10 minutes long crank again. if you shut it off and turn key back on but don't start it you can wait an hour then start right away. IDM bad? Vacation in 2 weeks and I would like to get this fixed first.
View 14 RepliesI've developed a problem, usually when starting, that the truck will crank over, start and idle for a few seconds and then shut off. The few seconds it idles it doesn't get any throttle input. I'll crank it back over taking a little more than usual to get it started. When it does start it seems slightly sluggish but that quickly, like almost immediately goes away and the throttle is working again.
Oh, 2001, 7.3 stock w/200k
I have an 02 f250 230,000, first 7.3. I've owned it since Oct and put less than 6,000 miles on it. I have another cold crank no start. New glow plugs and Glow plug relay last weekend. Worked fine that weekend. It sat all week, then crank no start fri night, it was like 70 degrees for the high that day. Plugged it in over night and it started. Did not fire right up cranked it for a couple seconds. I drove it all day, started every time. Valve covers have 5,000 miles on them. Fuel Filter heater fuse not blown. But don't know how to check it for sure. And don't know where to go with it from here. Getting frustrated with crank no starts. No troubles found.
View 2 Replies I got a 2000 7.3l with 400,000 miles on it that decided to just not start anymore after I parked it for a couple days. Its always been a hard starter due to needing glow plugs but I can deal with that. it doesn't even try to fire anymore. I replaced the CPS (my tack bounces when cranking). The ICP has oil in the plug so I just unplugged it for now till I replace it.
I pulled the IPR and cleaned it really good and bench tested it with 12 volts and could here it clicking so I put it back in. I can get under the drivers door with the key on and hear the fuel pump running. I gain oil pressure on my dash gauge when cranking. I check all my fuses. my WTS light comes on . I just don't have any fancy scan tools to make this easier. Also just cause I was feeling lucky I just went out and bought 2 new batteries for it yesterday so we are good there.
I have a 1997 F350 7.3 with standard xmission. Have not messed with it since Oct of last year. Then it would crank but no start. Now when I turn the key there is no wts or nothing the gauges move, and tach moves when cranking, but nothing else.
The cam and crank pos sensors have been changed. The high pressure sensors changed. Now when I hook it to the AE it says cannot connect to truck. Where I need to start? Have checked all fuses that I know about.
Friend's 2000 7.3 wont start, just crank and crank tried to fire but nothing in the cold leave it plugged in and it starts leave it in a shop over night and it starts with a shot of either, he is a truck driver and the truck will sometimes sits for 6 weeks at a time this time 2 weeks before I touched it. He wanted me to install a fuel pump so I did and started the following:
Cracked fuel lines to see if I had fuel psi at both heads
I tested glowplugs they all read at 0.3 on all 8
I have power to harness as the same at both sides of the relay
RPM tach jumps
Oil psi gauge rises
Using my phone I can read hpop and 2000 at cranking (how accurate that is im not 100% sure)
All fuses good
So I got all 8 injectors upgraded and excited when I get them back I put them all in in kind of a rush. And in that rush I left the cylinders full of excess oil. So obviously when I tried to start it hydro locked. Angry at myself. I kept trying to crank hoping it would fire and just shoot that oil out. Nope, so I went back to taking all the glow plugs out and firing it all back out. Put it all back together then tried to fire her up. Took a minute but she started and I let it run for a while. Hit the gas a few times and then it died. Couldn't get it started again. It would just crank, I checked the icp and ipr and the icp did not build above 35 psi and the ipr was at 98.04% so I just figured the o rings blew out when it hydro locked.
So I took it all back apart put new o rings on, took my time and put it back together right double checking everything. Got it all back together and went to start it, it would just crank around 160-170 rpms, battery voltage at 10.6 icp built up to 140 but now it won't build past 40. Ipr still goes to 98.04. The engine ran just fine prior to injector change, I put a new upgraded hpop prior to injector change, new ipr, icp, cps. Everything checks out, but it will not build oil pressure while crank I've killed a set of batteries then went all out and spent 350 at napa for some optima red tops. I did notice the cylinder 7 injector is the AE injector. It suppose to be in cylinder 8, idk if that's affect the oil pressure building up?
But as far as I know, I'm not building oil pressure. So idk if the hydro lock could have ruined something to keep it from building oil pressure?
So back ground is as such. Truck started fine before I replaced the hpop with t500 and did the driven diesel regulated return. I have double checked everything is plugged in. Now when I try to start it cold it will just crank. Yes I get smoke and oil pressure both places. If I give it a shot of ether it will start right up and run fine all day. What am I missing? Yes I know ether bad.
View 14 Repliesi have a 99 f450 7.3 that cranks but will not start. I did an injector buzz test but it sais no communication between the computers. it has a new rebuilt engine, new ipr, icp, hpop, water pump, and both computers.
View 4 RepliesFound icp sensor with oil in plug and codes p1211 and p1212. Icp sensor reading 0 pressure. Changed out icp sensor. Still cranks no start check oil level in hpop resverior, check with brake clean spray nozzle and no oil on it. Filled resverior with oil. She tried to start. Had to put the charger on her and she finally lite off and came to life. Questions, how would that resverior empty out? Was it because I pulled that sensor? Is there s check valve in that resverior hanging up?
View 2 RepliesNew to the forums, not new to fords. 1999 F350 7.3L Diesel. This has been a work truck and has seen multiple devices in and out over the years. I removed the last crap for GPS tracking etc from the last owners. The truck has worked well for a long time since until...
I'm moving slowly to a different state and so the truck got parked for 2 months. went to start it and nothing. the dash comes on and all the lights come on but when you turn the key to start the power drops and nothing.
Testing so far:
replaced the fender Solenoid
tested the starter motor and solenoid -passed
replaced the ignition switch
tested continuity of the hot and ground wires to the fender and starter and everything passed
When I shorted across the fender solenoid the starter works and tries to start the truck (unsuccessfully so far)
So the wire that goes to the fender solenoid is not working and where to trace it to and what needs to be fixed. Is there a relay or fuse besides number 30 that is in the way? where does the magical wire go so i can check its continuity?
I am stuck 800 miles from where i need to be and I am stuck here. I don't have the cash to get a mechanic and my mechanic friends are stumped. I do have a Snapon modus tester, what to do with it.
FYI the batteries are new and fully charged.
I have a 2001 E-350 w/7.3. When I start the truck first thing or when engine is cooled down it starts fine. I checked the high pressure pump pressure and it is 500 - 600 psi start up great. But when engine warms and try to start it it has long crank before starting. I checked pressure and it is between 425 to0 450 and takes awhile for it to get to 500 or better. Is this a cause of the high pressure oil pump ? I changed the oil and still does same thing. Also I noticed that after engine is hot and I try to start it, while cranking the engine the oil gauge does not move. I don't know if it supposed to when you crank it or not. I thought on other 7.3's I've worked on that the gauge builds up pressure....
View 14 RepliesAnyway, I went out to start my truck just now and I'm getting a weird symptom.
The truck gets partial revolution and then to me it seems like the starter bendix pulls back in prematurely and this nasty clank and then a slight "zing". all within a second.
If I try a few more times, it seems to fire. But all the attempts before it fires sound pretty nasty to me.
Does this sound like a symptom of a bad starter/bendix?
A little further history, my excursion was broken into several years ago and they stole my pioneer head unit, in doing so, they forced the shifter down and since then it has been a little "loose". I'm wondering if it could be a neutral safety switch on the transmission?
Anyway, I'm getting ready to order a new neutral safety switch but wondering if I should go ahead a purchase a new starter as well?
I have a 99 F3 50 with the 7.3 L I am done a lot of work to replace the HPOP pump and the ICP sensor as well as the IPR it cranks but does not start it will sputter and smokes but doesn't run SOS. Also there are no dtc in computer....
View 8 RepliesI 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.
I have an electrical problem on my 2003 f250 7.3 diesel. Sometimes it starts and sometimes it doesn't (mostly doesn't). I have two new batteries in it and have cleaned the grounds at the batteries and at the engine. When I go to start the truck all the lights in the dashboard work and it dings at me but when i crank the key nothing. I wanted to see if i was getting power to the starter and when I put my multi-meter down on the ignition wire on the starter and put my ground lead on the chassis bolt it starts every time.....I'm thinking this should not happen?? Is that a bad ground or a short or something else?
