what parts from a 97 to 95?

[ridiculously_necessary]

ok, ive about had it with this starting issue. i have a buddy with a 97 non-cali truck that has a dusted motor. so hes down for a while. hes willing to swap parts with me to diagnose my problem. what can i NOT swap over? can i swap in the ipr, icp, idm, pcm, etc?

Everything will swap. I know you've been posting but please give me a cliff notes version of the issue and what you've done so far.

[kanuck15]

Yeah only thing you cant swap is PCM if its a different trans, should be same year to year though

thats what i thought but someone posted something about non-cali slpit shows in a 97 a while back so i wanted to be sure.

cliffs notes version: its been running great for two weeks, thought it was fixed. once again as of this morning, completely random no start, started out as crank and no fire, but immediate second turn of the key it woudl fire. not that way anymore. its not batteries, glows, fuel fitler, starter, cps or gpr. im convinced its a sensor or electric related. seems when its warm (as in been running) it wont happen. mostly just happens at ambient temp, that is IF it happens. it could be 80* out and not start. i unplugged the icp no news. here is another thing that makes me think electric or sensor. when its cranking there is no attempt to run, little white smoke if any, actually not really any. on occasion, and rare one at that, it will sorta act like it tried to fire on one cylinder. and i mean sorta, and there will be a puff of white. so i feel the injectors arent firing.

here is where i am now
1. icp, ipr, pcm, idm or a relay.
2. fpr screen which ill check tonight (forgot all about this)
3. find someone with AE or have it towed, but who knows how it will act when it gets to the mechanic? it will most likely fire right up.

As long as his truck isn't a Cali model it will have single shots.
I would suspect the IDM, engine wiring harness, or a ground issue. There is NOTHING harder to figure out, or more frustrating, than intermittent electrical issues. NOTHING!

[ridiculously_necessary]

tell me about it. im in the IT field. random any problem sucks here too. but at least we have logs.

ok, so last night i get home and try to start, no go. before checkign the fpr screen i decide to crack the fuel filter. hardly any fuel in there. wtf? this is actually a first the other times there has been fuel. anyway, i fill the bowl and try to start, the batteries eventually run down. so i throw the passenger side on a charger for a few hours. when i get back home later i try to start it and it lights! at the bump of the key. this is what happeend last time too. when the problem starts the batteries are good the starter spins crazy fast. could there be a problem with the passenger battery? and the fuel bowl has me baffeled. why was it empty? no fuel on the ground or valley, last time it was driven was monday, no issues. plenty of power, and i drove it to work today, fired right up this morning.

[superduty4x4]

Have you had the batteries load tested? I'm wondering if while cranking they aren't putting out enough voltage to get the IDM to fire.

[ridiculously_necessary]

this is a good point. could just the passenger one cause this? ive never charged the drivers side battery. ill look at getting it tested, i guess next time it occurs...

When getting your batts tested, make sure you find some one that has at least a 500 amp tester. A regular small one used to test a car won't show a true reading on our batteries. I found that out the hard way.
