Car won't shut off...

[res7bequ]

earlier this problem came up where my car doesn't shut off. i can take the key out and put the alarm and whatnot and the engine stays running until i unplug the power to the power pack thing. its like its got a built in turbo timer set to forever... anyone got any ideas? btw battery died too and had to get jumped thanks in advance

Seems like you have an ignition problem. Do the lights, radio etc. stay on?

 

[res7bequ]

no the radio turns off and I can even turn the factory alarm on

 

[res7bequ]

it idles normally and revs fine too... pretty trippy

You could try resetting your ECU. Don't know if it will help much. Are you throwing a CEL?

 

[res7bequ]

always am... I'm going to run the scanner tomorow just in case to see if any new codes came up

Give that a shot. I'm curious what it would be since most the ignition CELs seem to be misfires. But that's not the case here.

Good luck nonetheless.

Anyone?

Have you checked out your starter at all? Check starter wires, solenoid, and starter itself. Maybe that will help you. I did a little research and this might remedy your situation. Let me know if it helps.

its actually the factory alarm. and thanks I'm going to check the starter and wires tomorrow, hopefully this is it because i don't enjoy having to remove the engine fuse to shut it off...

Check for a short to hot between the ECU/MFI relay and the ignition switch.

Hmmm, well that rules out dieseling. I will have to do more research on the subject.

I think dieseling was ruled out when he purchased an electronically fuel injected vehicle.

It is possible for a EFI vehicle to diesel, dieseling can occur in any internal combustion engine powered by spark plugs. Not trying to turn this into an arguement.

I suppose you are right, but a less-than-likely combination of events would have to occur, and even then it would shut down quickly.

My money is on a short.

Could be stuck MFI relay, or short to ground on MFI relay pin 2 (blue/green wire), or bad ECU (which is constantly pulling MFI relay pin 2 low), or bad ignition key switch.

I'm pretty sure you pull the battery terminals when you need to turn the car off, what happens when you put them back on does the car start back up or do you have to use the key.

if i disconnect the battery it stays on. though for some reason if i leave the car alone for a few hours my battery dies as if its stuck in the on position. Also anyone know where that relay is at?

btw thanks guys for the posts y'all have giving me some good ideas.

I'll trade you, my car doesn't start and yours doesn't shut off!

MFI relay is behind center console to the right of radio. Two relays there, left is fuel pump, right is MFI.

I'd be willing to bet that whoever wired it didnt set the time limit for it to shut off. All you should have to do to make it shut off (once again if wired correctly) is when you turn the ignition off and it is still running, push the brake pedal all the way down. Let me know if it works.

update: turns out it was the rewired fuel fuel pump... the relay and wire had some problems so it kept supplying power even when the key was off so relieved and thanks guys some good suggestions. hope this thread comes in handy to someone with the same problem
