Ford 7.3L Power Stroke (1999-2003) :: Little White Smoke After Good Warm Up - No Start
So I was on my way to work on a semi-chilly morning here in Colorado. Every day as usual, a little upset in the morning, a little white smoke and after a good warm up i'm on my way. About 10 minutes up the road while accelerating on the freeway, I hit I guess the perfect RPM range (2000-2500) when all of a sudden my CEL came on. Right as the CEL showed up, the engine introduce to me a new skip and lost a bit of power. About 5 more minutes up the road, the CEL went off and the skip went away, unless in idle. I made it to work a few minutes later and the skip in idle was apparent for sure. I turned her off and just couldn't get her to turn back on. The injectors are just not firing, no smoke at all, they don't even sound like they're trying to fire almost like no signal to the whole engine.
I replaced the CPS, the IPR and unplugged the ICP to test if she'd go. I opened the fuel bowl and watched it fill up. I checked the HPOP level, it was almost full, maybe a quarter (between half) inch from the top. No codes.
She ran great until this, outside of needing glow plugs. When I was trying to get her started it was 60ish outside so I don't think glow plugs is the issue. It sounds like the Injectors are not firing at all, whatsoever.
I will note that I had a few fuses blow out of no where that I replaced, a trail light, OBD fuse and one other in the under-dash box. I had her dyno'd a few weeks back and the tech said she made great power but sounded like she had a little issue recovering from the high RPMs but I figured my injectors are tired.
Ford 7.3L Power Stroke (1999-2003) :: 2000 E450 - Low Voltage On Gauge With Good Battery - No Start Condition
2000 Ford 7.3 E450 120,000 miles...
I have changed the CPS twice
I have checked the resistance of the injectors at the IDM connector with a volt meter and the harness reports back good.
The truck will run with ether for a few seconds
I have changed the fuel filter.
The fuel bowl fills quickly
I have unplugged the ICP.
The truck is showing low voltage on the gauge with a good battery. Around 10v
I have connected my 200amp car starter and I never see over 10v. I plan to check the grounds, but I am at a loss.
Everything is difficult because this is a van body so space is limited. I have also plugged in the block heater for an hour and that hasn't made any difference. Where can I get the best price on an AE scanner.
Ford 7.3L Power Stroke (1999-2003) :: A/C Won't Blow Through Front Vents?
After some diag I got the A/C to blow out the front vents. There are million threads on this issue half of them are never figured out. This is the second time I have come across this problem so will make this really informative for those who have this problem. If you A/C blows to defrost, yes most of the time its going to be a vacuum leak issue.
Step 1) turnkey on engine off, stand by passenger fender and listen.. can you hear the pump running? If it is your pump isn’t dead.
Step 2) does the pump run for 30 seconds then shut off? You may not have a vacuum leak. If keep’s running for ever you have a leak. Inspect all lines, especially those going down to the hubs for cracks. Also inspect vacuum lines under passenger glovebox.
Step 3) can’t find a leak? Disconnect the line going to the ESOF solenoid and plug it, if you pump stops running then your ESOF solenoid has an internal leak. That was my problem 6 months ago, replaced ESOF, A/C blows normally.
Try This Second! So my AC isn't blowing through my front vents again.... (more diag)
AC not blowing through vents and can’t find a vacuum leak? Take off glove box door, turn AC control switch to floor/defrost/front vents, watch the metal arm connected to the side of the big black box move up and down into various positions. I noticed on mine the arm will go down in positions (floor or defrost) But it will not move up! Which needs to happen to switch to front vents. If I push the rod up by hand manually, the ac will blow through front vents, and stay blowing through front vents even after I let go. PIC of metal arm thing connected to diaphragm, which changes air flow by moving flap inside the big black box
I am guessing the Diaphragm is the issue? The truck will continue to blow from the front vents even when the truck is shut off and restarted, it will stop when I switch the ac to a different position, it will not return back to front vents.
Ford 7.3L Power Stroke (1999-2003) :: Bad Injector O Rings Cause Blow By And Oil Consumption?
I have a 2002 F350 7.3L w/superchips programmer, k+n cold air intake. Does NOT smoke a lot from tailpipe
Not running rough since I changed my oil to rotella 5w-40w synthetic.
Appears to have good amount of blow by coming from the oil fill when engine is warm.
Can Bad Injector O Ring(s) cause blow by and oil consumption?
Ford 7.3L Power Stroke (1999-2003) :: Loud Pop / Boot Blow Off And Smoke Entering The Cab And Under The Hood
I was heading back into town the other day after fueling I accelerated to pass a vehicle then a pop not as loud as a boot blow off followed by smoke entering the cab and under the hood. After going into neutral and keeping the engine on to maintain brake power I came to a rest in a safe area. I was reading online some people rebuild these but I'm a bit hesitant given the tight tolerances of this part and currently leaning towards replacing the cartridge they sell at riff raff (500 plus new hardware) instead of the whole turbo (850). Now it's time to start cleaning the engine/undercarriage after the 255 mile tow home.

When I fire her up, the AC will blow cold for 10ish minutes until everything is up to normal operating temperature. Then it tends to blow warm, and that last for about 20 minutes, before finally settling back down and being cold AC again. I initially thought it was an issue with my compressor disengaging, but it doesn't seem to be...

My truck runs very rough and lacks power when cold, even during the Texas summer. Once it warms-up, everything is fine. It's almost like turning on a light switch. If it's plugged in for a couple/few hours, it's smooth as soon as it starts. I'm assuming it likes the oil once it reaches a specific temperature. What my problem is?

View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: AC Stopped Blowing Cold
My 02 F350 7.3 new to me trucks ac stopped blowing cold. Not air gap issue (shims have been removed prior to my ownership-I pulled hub and checked), the charge is good (according to the shop I went to for evac and refill), and the compressor's cycling quickly. I'm no HVAC guy by any stretch. I have a cheapie gauge from days long ago that I connected to my low side port (which I know isn't definitive) and it reads from 25 to about 40/45 depending on the cycle.
Additional info that may not be anything:
1) Where the line goes from accumulator to evaporator the foam seal is slightly messed up and I feel ice cold air coming out of the housing.
2) The line is warm before the orifice and cold after it.
3) The lines going to the accumulator are both hot (after taking it to shop, before were lukewarm).
4) The condenser doesn't seem to have excessive plugging and I have rinsed it with garden hose sprayer with no difference.
5) The air from the vents blows good, just warm.
6) I've replaced the actuator for the blend door already.
Ford 7.3L Power Stroke (1999-2003) :: Cold Crank No Start
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.

Ford 7.3L Power Stroke (1999-2003) :: F350 - A/C Is Not Blowing Cold As It Should
99 f-350 crew cab. The A/C is not blowing cold as it should. Have already replaced the compressor and clutch, orifice tube and accumulator, also cleaned evaporator coil and put a new blower motor on, also a new blend door actuator. Also put a valve in to block coolant from the heater core. System has had vacuum pulled and charged correctly by my mechanic, he says he doesn't know of anything else to do, that it was as good as its going to get. Ive been in 2 more trucks identical to mine and the A/C will freeze you out, as to where mine will not come close. Temp coming out of the vents barely gets down to 60 degrees

I just started having a cold start problem with my '02 Excursion this fall and I'm at my wit's end trying to fix it. Truck starts fine above about 45 degrees and when it's warm. If I plug in the block heater it also starts fine in the cold. If it's not too cold I can eventually get it started by continuing to crank it. It blows white smoke while cranking and for a few seconds after it finally turns over. Smells like fuel. Runs rough for 30 sec after starting when it finally turns over. Definitely seems like glow plugs aren't working. This truck started no problem on GPs alone without plugging in down to -20 deg F before this year.
I started by cleaning all battery connections, including the two ground posts on the engine block, I replaced one bad battery (diagnosed by Autozone; other one was OK), I checked the resistance of the glow plugs (only a few years old with about 30k miles on them) through the connectors on the GP control module (all were about 1 ohm), and confirmed 12V at the power pins in the GP control module connectors. I then replaced the GP control module and the problem is still present. Battery voltage drops from about 12.6 V before I start the GP cycle to about 12V when I turn the key to "ON" and the GP light comes on. How much should the voltage drop when the GPs are on? What the heck else could be wrong??
Ford 7.3L Power Stroke (1999-2003) :: 1995 - Oil Leak When Cold
I have a 95 powerstroke as a daily so I realize the common oil leak issues and where to start. Today at work I came in to our 2002 7.3 with a puddle of oil underneath of it. It's a service truck I'm the mechanic and I honestly after filling it could not get it to leak I tried everything. A guy had come in and started it after sitting for the holiday and it sat and idled and leaked probably 2-3 quarts. They shut it down and I came in I added probably 1 1/2 gallons to get it full again. Has almost 300k after I had gotten there they had already warmed the truck up and it had cooled back down. It's coming from the driver side (axle frame rail and leaf spring) are all covered in oil but no obvious signs when shut off idling under load anything of an oil leak. I tried everything to get it to leak and not a drop.

Ok truck would not start when cold outside. So I put a gpr on truck. Truck alt would only put out 11.5 ... After I put it on. So I put 4 new alts on all read the same 11.5 and the battery's would drain over night. Turns out they gave me a starter relay. So I have the proper one now. Now when u turn the key the everything is flashing the dash dome light buzzer. But take one of the small wired off the gpr, it stops but I have no power to the starter. It's been 2 months of hell trying to figure it out.

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 RepliesFord 7.3L Power Stroke (1999-2003) :: Truck Not Starting When Cold / Would Not Crank Up
I had issues with my F250 cranking last winter when the temperature dropped, so I changed out the glow plugs in the spring. I hadn't been able to truly test them yet, since it hasn't been cold, but the other morning my truck wouldn't crank up. It was 40 degrees out the night before, and it had been almost 24 hours since I cranked the truck, but it seems to me like the truck shouldn't have an issue in that mild weather.
I'm not sure what I need to do next to try and fix this problem, it's been driving me crazy and risks stranding me if I park for a while in an area where I am unable to plug by block heater in. The truck cranks fine when I have had it plugged in for a while, so I'm fairly certain it's a heating issue. I haven't done any tests since last year, but I know that the GPR was working properly last winter, which is why I changed out the glow plugs.
