    I was driving my car at work delivering pizzas when I had stopped to get gas. I left the car running, and dropped $5 bucks of premium into it. I hopped in the car, got to about 50mph and the engine completely cut out. I still had power and my dash lit up, as well as my head lights staying on. I thought "wtf" so I threw it in neutral while I was still rolling down the road and tried to fire the engine back up. Nothing happened at all. All of the power went out immediately once I turned the key in neutral. My headlights, dash lights, and every bit of power went completely black. Once I let go of the key the power came back on. I pulled over in a parking lot and had a friend come hook jumper cables to the car. When we try to start it, it will act like its trying to start normally, but never fires up. It makes all of the noises (not sure about fuel pump engaging noise) that its supposed to make when you're trying to start the car. The car just never fires.

    Can anyone give me some ideas on where to start diagnosing this problem at? I replaced the alternator the same day and I had recently had the intake manifold off (maybe one of the hoses came loose?). If anyone has any ideas I'd be grateful. Thanks in advance.

    UPDATE: Just hooked the car up to jumper cables and I dont hear the fuel pump engage on forward accessory mode or ignition mode. Bad pump? Is there possibly a fuse for this problem? And is there any fuel pump replacement guides w/ pics that anyone is aware of?

    Check fuel pump cutoff switch first. If it's not that, then you might wanna check if the switch and the fuel pump are getting power with multimeter.

    Where is the fuel pump cutoff switch?

    edit: Also isnt there some sort of reset access in the trunk? If so, where?

    It's located in trunk. Pull the carpet down a little bit on driver side wall, and you will see the switch.

    I think you are talking about fuel pump cutoff switch.

    Let me look for a picture for you. I might be able to find it somewhere.

    in addition to the things already mentioned, the ccrm could be bad - that powers the fuel pump, and of course the crank sensor could cause those symptoms too.

    Check the 10amp mini fuse in the under hood fuse box marked " IGN. FEED" If it is blown unplug the sensor from your coolant overflow bottle and leave it disconnected. Then replace the fuse.

    Mine did this also, When it blows the codes will not display and the fuel pump won't work.

    I have no clue what a ccrm is but the crank sensor would make the fuel pump not work? I can understand the engine not running from a bad crank sensor but it doesnt make sense that it would make the fuel pump not turn on upon accessory or ignition.

    well the fuel pump wouldn't have caused the weird power problems you described.

    Right. Well how can I test the ccrm? And does anyone have a picture of where the rest thing in the trunk is? I found a box on the driver side inner fender but didnt feel a button on the outside of it.

    Ok so even if the ccrm is bad does that mean if I install the fuel pump then it is likely to go out again? My cars electrical seems fine now. I'm assuming something was shorted, maybe some fuses are still blown or something but either way. I dont have time to keep this car immobile, I need it for work. I'm to the point where I'm about to replace the fuel pump for lack of any further knowledge regarding why my car wont work, and if it blows again, get a new fuel pump, and maybe ccrm. After that, check the CPS. After that, I'm going to blow up my car for the 4th of July.

    haha :rofl:

    I'm having the same problem with my car. don't know which it is yet but leaning towards the crank sensor. If you feel like it, search "car stalls around low idle". I can't change the title but if i could it would read car stalls intermittently

    a bad ccrm is unlikely to kill the fuel pump, but the fuel pump will not work if the ccrm is bad, so changing the fuel pump will just be a waste of time/money if the ccrm is bad.

    the crank sensor being bad can cause the no-start symptoms you have, but will not hurt the fuel pump - sorry if I was not clear in the earlier post.

    Would a bad ccrm disable the fuel pump prime? I dont hear the fuel pump prime anymore and I could clearly always hear it ever since before this happened. How do I check if my ccrm is bad ?

    And also, if the ccrm is fine, is there any other possibilities of the cause of this? I still havent found the fuel pump relay in the trunk. I found a small box inside the driver side trunk body that has 2 red caps on the outside that cover bolts. I cant see the actual device but this is all ive found so far. If this isnt it can someone guide me in the right direction of finding that reset switch?
