did you try backing out the two screws in the middle of the PCM? they are known to short out the pcm because they are too long.

i was thinking that, but the more i searched the more i kept hearing symptoms such as stalling while cruising at a constant speed. mine hasnt done that at all. it stalls when stopped at a light.

i just realized that. the reason why i did not suspect that at first is because i forgot i had my horn removed (for installing a new rad and reinstalling my kor radiator support) so i couldnt hear it going off lol.

and yeah my battery was low cuz i was playing music all day on it while working on it. once i jump it and drive it around/let it idle its fine.

do you have a factory alarm?
If it is set armed it will disable the running of the engine. It will fire up and die.
The lights will flash weirdly even after the battery is disconnected.
The key interlock on the drivers door deactivates the alarm, if the switch is bad it wont disarm when you open the door with the key. But then the lights and horn should also sound.

I think you can deactivate the alarm by wiring the key wires to ground or together like the key would do when you put it in the lock.

I would be surprised if the computer had failed.

yeah its factory.
that is what the lights were. and most likely what wouldnt let it start.

yeah iv seen the ol' yellow purple wire trick

and from what iv heard its not all TOO uncommon for the comp to go bad.

so have you gotten it to run after you disabled the alarm? if so is it still stalling? Usually when the PCM starts to go bad it screws with all the sensors and that's why it stalls. Mine would run great if I disconnected the battery and as soon as it warmed up it would stall.

That's definitely got to be something with the PCM/Crank sensor working together throwing off the timing enough to cause it to die.

Have you tried unplugging the negative cable on the battery overnight and trying it again? I believe after about 15 min. your PCM gets reset, so you really don't have to leave it unplugged overnight, but its worth a try. That will also reset any alarms or anything that is being triggered. Might run a little rough till the PCM relearns the operating conditions again.. if the engine starts normally.

Then, I'd look towards the Crank sensor that controls timing.

turned off the alarm, and it started right up no prob.
nash will be sending me a pcm here soon, an im thinking about picking up a crank sensor at advanced autos (theyr like $50). plus i know a manager there, he also drives a black 96 limited 5.2
so maybe ill be able to but it and if thats not the problem he could prolly let me return it for a full refund.
im starting to think its the CPS more than anything now.

i didnt get a chance to drive it tonight tho..

it won't be long till I give you mine....geez...you ain't my son and I sure am going broke due to you...I hope College pays off...n/m you went to Ohio State and not THE U of TEXAS.
seriously the ecu will get sent out this week (probably tomorrow) so hopefully that works for you. The only problem I have is when I get my stroker motor in...I will have to have my ecu reflashed all over again.
