97 F250.... so 24 year old a/c bearing finally quit.
original a/c components....nothing has ever failed....amazing.
Does a new clutch assembly include the bearing ?
unfamiliar with a 92 f250, but it's low pressure being transmission fluid. Not seeing it in person, is there a way to cut the line where it broke, flare the ends and splice a piece of rubber hose with clamps in it's place?
completely different transmission, sensors, dash, etc. Won't work.
What is the 4 digit box code on your existing PCM. There may be substitutes that will work besides an identical box code. The main differences being cali emissions, cold weather, etc.
coolant tank increasing capacity isn't good. Let it settle and see if it's diesel. If so, you've got bad o-rings or injector cups
what was the code? Fuel pressure isn't monitored by the PCM so it's probably oil related.
This. I've never used the fuel bowl drain since I replaced all the o-rings on both trucks due to leaks. The old filter absorbs enough fuel so that the new filter goes in without spillage.
I would order a fuel pressure regulator rebuild kit

some shim the regulator spring to increase pressure to 70psi or so
on the OBS you can check the fuel pressure at the schrader valve at...
Do you still have the EBPV intact?
If so your best bet is to gut the valve and plug the actuator. Leave the EBPV connected electrically but open to atmosphere.
What codes are you seeing for the EBPV ?
What year truck?
fuel regulator ever been rebuilt?
screen cleaned at fuel bowl (OBS) or in tank screens (SD) ?
oil contaminated ICP sensor ?
IPR nut tight against solenoid?
transmission range sensor (OBS) ?
no WTS light would indicate the PCM isn't getting power during the restart.
I'd look at bad grounds, ignition switch, even the fuel bowl heater shorting intermittently but not completely blowing the fuse?
stock @ idle can be as low as 500ish
stock @ full throttle should be around 2800ish
as stated IPR duty cycle would indicate how hard the hpop is working to make that pressure (or lack of)
What's the actual voltage at the batteries with the engine running ?
Sounds like it's definately the chip causing the issue.... whether it's the chip itself or the PCM port the chip attaches to.
sounds normal
did the truck run fine after removing the chip? No issues without the chip installed?
could be something related to the tuning and how much it "works" the engine compared to stock. I'd be thinking IPR solenoid, etc.
unplug injectors one at at right at the injector. no change in idle indicates the injector isn't working. change in idle means you've disconnected an injector that is firing.
Any codes?
as mentioned, try buzz testing the injectors to check the electrical side. if not the uvch it could be worn...
fuel bowl was full. Not sure if there are check valves besides at the heads, and I believe those are only screens.
No fuel came out of the lines going to the heads when disconnected from the fuel bowl. No fuel came out of the fuel bowl either.
I suppose I could disconect those lines on the 97...
something odd today
went to replace the o-rings on the two lines going from the fuel bowl to the heads. When i took them off at the fuel bowl ZERO fuel leaked out. How could this be? I was expecting fuel to be sitting in the lines.
This is on my 99 which is always louder than my 97. Now it...
best bet is to find a shop where the mechanics still smoke cigs and have pictures of scantly clad ladies on the walls... chance are they are actual mechanics and not 'techs' that just swap parts
