Engine stopped running and will not start up?

It sounds like you got water in the fuel. When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?

Please run down this guide and report back.

Yep, I dropped the tank and installed a new pump while at the same time I flushed the tank out you could see water in the tank btw, she runs great again! thank you so much

car starts and immediately stalls. suspect a problem with security system. (factory passlock) won't run on ether and has fuel pressure when it stalls. went so far as to bypass fuel pump controls. checked all pcm hots and grounds.i have power to ign. module and coil. information i have on passlock seems to indicate that it disables engine by interrupting fuel pump circuit. (not energizing relay). i bypassed relay, still nothing. does the passlock disable ignition? thought about crank sensor but am not aware of these being an issue. it is difficult for me to get a reading on sensor with my scan tool. i have limited data reading capabilities. i am starting to suspect pcm.

try resetting security system see pic

tried the relearn procedure to no avail. after start attempt, the security light does not remain 'on'. waited the 10 minutes anyway and repeated the procedure as per instructions. no good. any further ideas?

then go to the old standby and scan for codes and check fuelpressure with agauge autoparts rent it. also check fuses underhood

tried all this before i submitted the question initially. thanks for trying. how do i get a refund?

I turned it in so you should have it soon.

We are sorry we were not able to help you. Your refund is complete.

the engine just died, it turns over no spark? fuel pressure is good and lines good

no spark? none of the cylinders are getting spark? use a spark tester to find out if its putting out little or none.

check the crank shaft sensor for resistance and voltage when cranking.

getting +12v to the coil wiht key on?

i am having this same problem, i do have 12v at coil plug in, also ground in connector , but the center wire which is blue gets nothing during spinn over.trying to find a ignition diagram but no success yet will not give up. i will let u know what all i had to do to fixxx
