Ford 7.3L Power Stroke (1999-2003) :: No Start After HPOP Reseal
Pulled the HPOP reseal an oring that was leaking oil. Feel confident that I made sure the check ball stayed in place. Torqued the bolt to 96 ft lbs. Have fuel in the bowl.
We have cycled the starter about 20 times for 15 to 20 seconds. Batteries are charged.
Here is what the AE scan tool is saying after a few seconds of cranking:
ICP -160
IPR - 0.43
Duty - 63.67
Do I need to get a different reading/test.
I have read about stuck open IPR valve giving the low pressure problem, but the truck was running prior to pulling the HPOP.
Lets say I left out the check ball. Would the scan tool show 0 pressure? (Trying to rule out the check ball)
How about if I didn't get the spring seated in the high pressure oil fitting and instead it is hung on the threads and is compressed inside the HPOP. Could that be the case?
Not for sure it makes a difference, but the truck did fire off once on Ether for second.
Ford 7.3L Power Stroke (1999-2003) :: Replaced HPOP Now No Start
This started out as a turbo pedestal O-ring change (leak down the back of the engine). Since I was going to take everything out to do that I figured I'd reseal the fuel bowl and hpop. Wound up replacing the up-pipes as well. Went ahead and changed the ICP and CPS. The truck started rather easy as I've heard its hard to get the air out. I drove it about ten minutes and then noticed it was leaking oil so I went back to check it. I found that it was leaking from one of the output fittings on the hpop as I guess when I tightened it back up after putting on new orings I damaged the pump by over tightening.
The oring and fitting were fine it was on the pump threads I guess. Anyway trucks got 280k miles so I just bought a new hpop from the stealership. Went home and installed it and the truck won't start. Pulled ICP out and cranked no oil coming out. The only other thing would be ipr (I cleaned with brake cleaner and air tip before putting in the new pump) so just to know for sure I bought a new IPR from the stealership and still NO Start. I didn't fool with anything else don't know what it could be. I checked the bolt in the front cover (tight), got to be a BAD (new) pump right.
Ford 7.3L Power Stroke (1999-2003) :: Hard Start When Hot - Can't Find HPOP Leak
I'm having Hard start when Hot problems, starts fine when cold. It takes a couple of minutes of cranking for ICP numbers to hit 500.
So far I've replaced:
ICP sensor
IPR
Injector O-rings.
Still didn't fix the problem.
I also washed out the engine, and put uv dye in the oil, let it run, to find any external leaks, but I found nothing. I don't thing it's the HPOP, because it's able to sustain high ICP numbers when I hold down the throttle.
My next step was to remove the HPOP and replace all it's o-rings, but I assume since I don't see any leaks, the o-rings aren't the problem. Is there anything else to check, that could be causing low crank ICP numbers when hot?
Ford 7.3L Power Stroke (1999-2003) :: HPOP ORings Replaced - Injectors Loud After Start Up At Idle
Just replaced all hpop orings. Injectors loud after start up at idle. Guessing air in lines. How long do I need to drive before all air out of lines and everything back to normal?

Ive got a 99 7.3 with 250,000 miles on it. It has run fine all day but just jumped in and won't start. It cranks over but won't fire. Check engine light doesn't come on. About two weeks ago it cut off twice at idle but haven't had that problem since.

I have a '99 7.3 that I am working on for a friend. He was moving out west and got to the next state. He stopped to use the washroom, when he came out, the truck would crank but not start. He had it towed back to my house. I have some diagnostic information. Fuel pressure measured at the fuel rail in the head is 60 PSI for the passenger side head. I pulled the plug on the drivers side, it was under pressure and sprayed fuel.. I did not measure it there.
WTS light comes on and then goes off in a normal time frame. Tach shows around 500 RPM while cranking. Engine oil pressure on dash gauge builds up and Low Press Light goes off. Pulled the plug on the High Pressure Oil Res., oil is present at the top. Are there any other checks that I can do until I can get a scanner. My friend has a Snap-On, but he's almost 100 miles away.
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Cranks But Won't Start?
I have a 2003 f250 with the 5.4 in it. When I bought the truck the odometer and fuel gauge weren't working. So I tried disconnecting the battery and when I hooked it back up the odometer started working again and the fuel gauge went from below empty up to full then just dropped back down to below empty and won't move at all. I haven't tried disconnecting the battery again. And I know more than likely I will have to replace sending unit but trying not to if I don't have to.

My '99 f350 lost a lot of power the other day, turned out the the injector harness got unplugged. So I swapped those out for oem ones, ohm tested the uvch and injector harness, put a brand new GPR, and still nothing. Cranks over but won't start, what else could it be?

This past weekend I noticed I was loosing boost pressure on my 2003 7.3l F250 so I pulled my turbo out found the problem fixed it then put the turbo back in. After it was all said and done I went to start the truck up and it just cranked and cranked a cranked but no start. Worried I didn't hook something up right I checked and rechecked everything to do with the turbo, all good nothing out of the ordinary.
I tried to start again, nothing. Spent all day yesterday trying to figure this out. Replaced the cps still nothing. No movement in tach but I don't remember any on startup anyway. Drained the fuel filter had adequate pressure and such but replaced the filter anyway. Still nothing. Checker all my fuses, one by on and non were blown but I still tried disconnecting my fuel bowl heater and still got nothing. I tried disconnecting the Icp still nothing. There was no oil around the icp either.
I'm getting frustrated that the truck wont start, the truck ran perfectly fine before the turbo removal but now wont even give a sign of kicking up. Just cranks and cranks. Also checked Hpop to see if that's the cause and it's filled like to the brim. But when I'm cranking the truck about 10 sec into the oil pressure gauge kicks up and reads good but only when cranking.

Ford 7.3L Power Stroke (1999-2003) :: E350 Cranks But Won't Start
I have a 99 Ford e350 7.3 Powerstroke with about 150000KMS on the clock. However I am having a really hard time starting it in the Cold Canadian Winter (-30). Last week I changed all 8 glowplugs, the batteries, the oil, fuel, fuel filter and yes i always keep it plugged in.
It cranks really well, but it just wont fire not even with a shot of start fluid. I don't know anything about these trucks much less a diesel engine. A guy took a look at it and said my engine needs to b replaced. (I think he is wrong)....
Ford 7.3L Power Stroke (1999-2003) :: 1999 - Cranks But Won't Start - Water In Fuel Light On?
My 99 F350 cranks, but won't start, and the "water in fuel" light on the dash stays on while cranking. I have never paid close attention to it in the past. Is it supposed to be on while cranking?
I drained the water from the yellow lever located on top of the engine, and tried to start it. The light went off for the first few cranks, but again the truck still will not start.
I just came from a 10 hours round trip to NC. I filled the truck up two times from gas stations on the way. Is it possible that the fuel is bad? I drove on the same fuel almost 3/4 of this tank and now at the last 1/4 I am having this issue.
A little update:
I took the top of the fuel bowl off to see what the filter looks like, and it is nasty and completely black. I could not tell if the fuel in the bowl contained any water, but it looks greenish and uniform, no the obvious separation that happens when you mix water and oil.
Could the fuel filter be the problem?
A little history about the truck. It's always hard to start if cold and not plugged in overnight. I know it's the glow plugs relay, so I just keep it plugged in all the time until I get a chance to fix it.
IDM was acting up shutting off half of my engine, but I took it off, cleaned it, plugged it back in and it has been working fine for over 2 months.
Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 - Cranks But Won't Start

No matter what it won't start good batteries cranks good but no start ...
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Cranks But Won't Start - Relays Clicking?
So I have recently did a body swap on my 7.3 I rolled. Put a body from another one this one. Before I took the old body off the engine ran fine. Nothing wrong at all.
Now that I have the new body on, I am stuck with a fuel shutoff switch. I read that it is suppose to be pressed down, but when it is pressed down, I turn the key and 4 relays under the hood click rapidly, 2 under the dash, and the drive side blinker blinks? Anyway, when I push it up, and turn the key, all the lights come on normally, wait to start light comes on. It'll crank good, the battery's are good, had them tested and fully charged. Checked ando triple check all battery connections and grounds. Anyway, it'll crank and want to start it fire up for a second and die. The low pressure oil gauge on the dash doesn't go up, but I think I broke the sensor connector for that. The fuel pump doesn't make any noise, the fuel bowl has fuel in it, but does fill up with fuel. So I'm thinking the fuel pump is somehow shorted out, so when I depress the fuel shutoff switch it makes everything go crazy. But even then the fuel pump doesn't make any noise?
Ford 7.3L Power Stroke (1999-2003) :: F250 Cranks Great But Would Not Start
I have a '99 F250, 7.3, CCSB with just over 127K on the clock. I went out of town for 10 days and was ready to get out of the grocery getter and into my truck. I hop in and it cranks great but would not start. I pop the hood and start with the easy stuff. Made sure all plugs/connections were good, check. Relays and fuses are still in good order (under hood and dash), check. Fuel pump was replaced less than a month ago (works great) with fuel in fuel bowl (new filter), check. Try to start a few more times with no luck, so I tinkered around for few more minutes and it starts right up and drives perfect.
Drive around, truck is on and off as usual throughout the day and go back to work next day around 10:30. Truck starts as normal. Get to work and have to run out but truck doesn't start again. After key is in on position for 15-20 minutes while checking fuses and such it starts up and runs perfect. I drive around for 20 minutes and return. I got off about 5 hours later and it doesn't start. Leave key in on position while I'm explaining issues to a buddy again 15-20 while key is on it starts right up. I drive home and park and I haven't been able to start it since.
From reading forums and watching you tube I'm leaning towards IPV or CPS but no one has described the problem as I've had. I do not have monitors, tuner, or anything aftermarket but I'm a mechanic and have a descent set of tools at home.
Ford 7.3L Power Stroke (1999-2003) :: Cranks / No Start Sometimes Stalls At Idle
1999 7.3l 6spd standard 4x4. Just bought the truck 4 months ago knowing it had a problem that once warm occasionally would t start. Happened a few times every week or two. But wait 15 minutes and the truck would fire back up. Then it started happening more often throughout a day. And I would have to wait longer for it to cool to start it up.
Icp has been changed
Cam sensor
Pulled valve covers to check to see if there were any injector o rings failing. They were all good. Put it all back together.
Pulled the IPR and tore it apart cleaned it all out
Started driving it ran great for a week. Then today sitting at a light the truck died just as if I had turned the key off. Wouldn't start for 3 hours. The. Fired up. Took it to buddies show and started checking things out again. Both batteries load test great and fully charged. Alternator pumping out 13.5 and up.
Codes i have pulled are waste gate to high /low
I forget the number for that one. The second was P1211. Cps has been changed and ipr cleaned. Think that I should replace the ipr of this happens again?
I did get w code a few weeks ago about low voltage at module. this code doesn't appear anymore. Since I checked the plug ins all looks good. But the PCM wasn't mounted properly. So I fixed that up and checked battery connections. They were very good so I re did all of that.
Anyway. Back to the problem. After ipr clean. Drove as she should until sitting at a light a week later. Truck just quit. Would t start back up until cold. Any thoughts. New IPR? Oil in hpop within half inch from top. And I don't seem to have any oil leaks. Did oil change fuel and air filter. Not low on any fluids. I had a 1997 too and threw a bunch of cash at it like this one trying to find the issues.
Ford 7.3L Power Stroke (1999-2003) :: Service Engine Soon Light Comes On For A Couple Minutes At Cold Start
On my 7.3 super cab, I changed the fuel filter last Friday and now on cold start the service engine soon light comes on for a couple minutes (approximately) on a cold start. No other issues. Tried scanning with my scan gauge 2 and no codes. (of coarse I think that thing is a joke for scanning). Not sure if this means anything, but last week before I changed the filter I thought I smelled diesel fuel on a couple different occasions. If I actually did it may not even be related.

I have an issue with my 2001 f350 7.3 PSD. Intermittently it will not start. It will crank really quick, but will not even try to start. I think it is not getting fuel. There are no CEL codes and I have a WTS light and the tach is moving while cranking. I hear a clicking/buzzing sound coming from under te center opf the dash. When I hear that sound it will not start. checked fuses and relays and it started before. not sure if removing the fue made whatever reset. this has happened a couple times. Now it will not reset. When I remove the number #24 fuse under the hood, the clicking stops. when i crank it, but still doesn't start. When it starts in runs perfect. Drained the batteries trying to trouble shoot, but have them charger now.
