Car shuts off

[Marlinlane]

I am having a pretty serious issue and starting to see on the net that it seems to be an epidemic. I have a 2005 and it will, without any consistency, shut off. Whether parked, driving 60mph, cold, hot, it will just out of the blue turn off.

As you are driving, the car will simply drops rpms for 2 or 3 seconds at the most, then shut off. There are no noises, nothing visual, and it cannot be repeated with any routine.

Has anyone on these forums experienced this and if so, what was your fix. I live in the Florida Keys where our mechanic situation is less than optimal.

Check alt...make sure battery connections are tight

check the fuel pump drivers module although they just fail without warning it would be worth looking at for any signs of corrosion.

The fuel pump driver module (FPDM) is located on the top of the LH frame rail near the fuel tank filler pipe.

This also sounds like a recent thread about the engine shutting off. In order for that to happen you have to loose fuel or spark. Trouble now is that they are so complicated it could be just about anything with either system. You need to look at both systems to narrow down the culprit.

In the other post they changed both crank and cam sensors to fix the problem after looking at the fuel system. Along with the above suggestion hook up a decent scanner/code reader to see what values those sensors are feeding to the pcm.

Without diagnosing further it is just a crap shoot right now. Once we have more information we can steer you in the right direction.

Mine did the same thing hot.cold park or driving it would shout off ended up being the fuel pump

That is why I always check fuel pressure first when they die. It is one of the easiest tests to perform and usually will point you in the right direction.
