AE compatibility and other questions.
I bought a 1995 F-superduty PSD. 210,000 miles. On AE's website it says the f450-550 etc are not light duty and will have no support. Also, 1995 is not listed in the ford package. I'd like to be able to run tests instead of throwing parts or paying a shop for diagnostics.
I bought it non running because PO had taken the CPS out and didn't have money for a new one. It had sat for a few months. It supposedly needed the CPS replaced. No CEL is on. It does turn on for about 1 second when I turn the key on so I know the bulb works. The EBPV is open, and moves freely. I can hear the turbo "whistle" when it gets over about 800 rpms. I put a new CPS in (purple oring), new fuel filter (there was fuzzy crap all over the old fuel filter even though it was changed a year ago), changed oil and filter, filled coolant and checked the ICP sensor. The exhaust is currently just dumped under the bed. They were gonna put stacks on it. WTS comes on, it starts and it runs. Tachometer works. First 5 seconds idle is rough and loping and then smooths out. With the pedal to the floor at first it won't rev past 1000rpm. It's like the injectors fuel supply just cut out. The longer I run it and mess with the throttle pedal the higher it goes. Yesterday it went up to 2200 rpm. When it gets to the cut out point, whether it is 1000, 1500, or 2200 rpms, lots of white smoke. It does the same thing in all gears, and accelerates very slowly. Every once in a while I feel a spurt of power. I'm gonna fill the front tank and try different tanks. Any one got any pointers? I'm going to check fuel pressure at scrader valve, and the "intake boots" for leaks. (if that's what they are called). I'm going to check HPOP oil level, but my understanding is it wouldn't run if it was low. I'm also going to check the TPS on the pedal. I have checked the idle validation switch and it appears to work the way it should. If I push it while the throttle is depressed it returns to idle. Thanks for reading and any advice!
