still no fire help needed

[F1atlander]

well my car lost fire again. ive replaced the ignition module, PIP, and coil. car runs great then just drops ignition fire. after an hour of sitting in the cold it fires up great again. the car wont even reach normal temp then die. anything else i can replace?

Maybe the ect is going bad? I don't think it would cut fire to the car tho.

TFI module? located on the fenderwell by the intake tube unless you've moved it. Try cleaning that off and putting some new dielectric grease on it or maybe just replacing it?

check your engine and ECM grounds. Also, if your car is chipped... make sure it isnt wiggling loose on you.

 

[F1atlander]

dont have a chip and already replaced the TFI module with a motorcraft part.

where is the ECM ground? im guessing in the passenger kickpanel with the ECM?
i did notice while doing my head swap that the head wasnt grounded to the body like on most cars.

thanks for the suggestions so far.

 

[Addermk2]

the ECM ground is up near the battery, on the radiator support.

make sure you have a ground strap running to the block from the negative battery terminal

 

[F1atlander]

checked all grounds and im getting great continuity.

gonna replace the whole distributor today with a motorcraft part since i got the last PIP from o'riellys

 

[F1atlander]

well the distributor didnt help. ive never heard of an ECM going bad on a 94-95 car or even on a fox, but im running out of things to replace lol

Shot outta the dark, have you checked any fuses? Don't know if this could do anything but it seems like it could be overlooked pretty easy

no not yet. this 13* weather in GA and sleating rain kinda slowing me down on it.
worst part is the car is at the quiktrip across the street from my shop. ive already spent over $150 this week on tow bills alone. but might have to do it one more time now that the car is not magically fixing it self so i can finally start testing for the problem.

I'm stumped too.

:laughing4:


waiting on a car trailer now. just hope getting it on the trailer doesnt make it start firing again like last time. :angry4:
gonna hook up the lab scope to the ignition and trace down the problem tomorrow.

how about if we close our eyes when we read your reply

 

[sn95gtvert]

i wish my car was the same color as these guys!

my car did this sort of thing but totally at random, ended up being my battery terminals they looked fine but when i took them off the ground sheered in half.
just my .02

good luck!!

i had the same thing with my fox...wasnt the ignition at all..bad fuel pump..the stock pump got hot and shut down...after resting for a while it would fire up and run for a few minutes...then shut down..couldnt figure it out..one day it happened as i was passing a gas station and i need fuel so i put fuel in which cooled the pump and it fired right up...so i knew it was that after that.i put a 255 in after that and it never happened again.

 

[Insayne]

+1 ive heard of that before.

 

[F1atlander]

no its getting fuel, just no fire.

i hooked up the modis and tested the the new PIP and new TFI and they are both testing good. car has fire with the spout connector out so im waiting on an ECM to get here. never had to replace one in any year mustang tho.

 

[Addermk2]

you have spark with the SPOUT out?

what the vuck?!

 

[F1atlander]

yeah its was new to me too. my Snapon MODIS used it as a test of the EEC. after doing a little research and its a common test for ignition diagnostics. got the ecu out today but was to busy to put it back in. should know something monday.
