Awesome! Going to call around see if i can get a used pcm

 

If fuel pressure is good, 49 psi, then I wold suspect a faulty leaking injector, if it is indeed flooding. Any chance you messed with the fuel sync?


Edit: also when it is acting up are you making sure you haave spark? I had a similar issue and turned out that mt coil was firing intermittenly. Faulty wiring in the asd wiring.

 

inj have been pulled and tested(each one), and i replaced my coil. Today replaced all my relays and checked all my fuses... how would i have messed with my fuel sync? (is that done with the dist.? anyway i havent messed with the fuel sync as far as i know.

 

Yes fuel sync is changed by moving the distributor.

 

thanks. well pcm is fine(had it tested)... So now i am really stumped.. any chance an air bubble in my cooling system could cause this? sayyy if it was at the location of my ECT sensor? could a bad head gasket cause this?(not that i have one.. just curious), what about adding coolant stop leak to my coolant?(yes i did this as it was an emergency to get me home...).

 

Any chance you have a plugged catconverter?

 

I think his cat is gutted.

 

Air bubble? Maybe, but, don't hold your breath.... could loosen up the sensor while the engine was nice and toasty warm, and let a little coolant bleed out to make sure it isn't the problem though. (Be extremely careful.... just let it weep a bit, no need to pull it out, and in reality, that would be a bad idea. )

What would be nice is if you could do some data logging... and see what all was going on.

 

threw a known good pcm in and still a no go.. so now i am going to be testing sensors at the pcm via the wires going in(find warms for ect sensor at the pcm and test those..etc) figure next is pull my plenum and do it and do heads at the same time. i am totally out of options.. i am going to leave it in a heated shop tmrw night at about 85 degrees and see if it starts hard in the am(to see if its temp or time related..)

 

sure reminds me of high school auto shop when the teacher use to bug cars and we had to find the issue... i remember one car there was a safety switch in the trunk he bugged that caused a no start issue, that took 2 weeks of 2hrs a day 5 days a week to find... lol
