Default 1996 mustang GT 4.6 won't Start

Need help. Was driving and hit a bump. Engine shut down and now car won't start. Doesn't appaer to be getting power to the fuel pum/ignition. Theft light is now blinking real fast even with the proper key inserted. My OSBII will power up when connected, but it will not communicate with the PCM. Any ideas?

Ummm whats that thing called... My friend's 1999 Ford Taurus had some kind of sensor and automatic killswitch in it that prevented the engine from starting after an accident or serious bump, had to do with fire prevention I think.

I can't remember the name of it, but she had to get it replaced to get the car to start and run.

It would start and sputter out.

Dunno, just thought of it with the 'ran over a bump' thing.

Good luck!

This happened to me once... I was told it was a safety feature... I bumped into a parking post at about 2 mph... the engine shut down and wouldn't start. It was a '89 or '90 5.0 I think... It was a rental - so Hertz picked it up - never learned anymore about it... Except were some sensors in the bumper to protect from fuel tank igniting...

Hope this helps...

Not sure about a sensor that disables the ignition system....I had an accident ($5,000 worth of front end damage) and my mustang started right up afterwards. Granted it wasn't a '97 it's an '01! If the early mustangs have this, then it is certainly something to look into though!

Sound like a wire came loose to me!

I would check all wiring in the engine compartment. I would also disconnect battery (if not already done) and disconnect your engine wiring harness. Then hook it back up and reconnect the battery!
Next I would check your connector to the pcm and make sure it didn't jar loose.

You could be in for quiet a troubleshooting experience here. It could be a number of things if it is a wire that either shorted or came loose!

Sure others on here will chime in with things to check......sorry I couldn't be more helpful but it really could be anything, certainly sounds like a short somewhere or a wire came off.

Does it attempt to crank over? Do some or all electrical assors. work (lights, stereo, ect...). Does your check engine light flash or come on at all when key is turned to the on position????

Just trying to narrow things down!!

Thanks for the replys. I checked the fuel pump shutoff and it is OK. Even jumpered past that. I checked the PCM plug as well and everything this is OK as well. I did find some wires underneath the car broken and somewhat fixed that to see if that worked. NO LUCK. The Theft light on the dash is blinking real fast now, didn't before even turning the key on doesn't stop it. Use to come on then turn off after key was turned on? I guess I can disconnect the battery and see if that resets anything. Lost!!!!!!!!!!!!

If you found some broken wires under the car I would focus my attention on them first! Even if I quick repair was done, I would try to track these down. It may point to your problem area!

What do these wires goto (any idea)???
Did the car bottom-out and hit the ground???
