Engine Running Funny, Cuts off with low RPM Options

[Jaws4God]

Hey guys.. need advice please!

I was repainting some of the engine parts last night for a show today, Repainted the valve cover, and a few of the fuse box covers.. well when I get back in the car the next morning.. it won't start. No click or anything.

We thought it might be a dead battery, so we try jumping it but still nothing. Headlights come on and look bright so I think battery is fine.

We then figure its the starter, so we pull it out and go to Advance Auto and they check it, say its bad. So I replace it. But still.. nothing.

Then I noticed my Viper alarm isn't working at all.. looks like it has no power. So I find the wires that run to the ignition and find one for Starter Output, unplug that and still .. nothing..

so now i'm at a loss.

If anyone knows what it could be or a way to help find the problem. PLEASE let me know!

Thank you all!

check the fuses maybe one of them loose from you opening the cover; or the wires coming out of the fuse box , that happens to me on my 1987 GT.

Update..

checked some fuses, found the 30amp AM2 fuse is blown (under the hood in right side panel) Stuck another in and it blew. Not sure what all that powers but at least its a start... any ideas or clues, let me know!

Thanks!

did the new fuse blow when the ignition was in the off positon? if so then there is a short to ground somewhere between the fuse and ignition switch

i was thinking the ignition was off, but I can try testing that.

Thank you all!! Please keep suggestions coming!!

If your AM2 is blowing, which would definitely keep your car from starting, check the distributor and coil.

the fuse does not blow when the ignition is off. but when i turn it to on, it blows.

does anyone have any diagrams of the distributer and coil for what wires are what and were to start looking?

ok, so it does blow when the ignition is turned to the on position, thats where the short is. here is the start/ign wire diagram http://www.celicatech.com/imagearchive/bgb...ewd/circuit.htm check the wiring and componants that come from the B-O wire, pay special attention to anything you removed etc. since it sounds like you might have accidentally caused the problem.

Well my friends dad just came over and helped me do some more tests.. we found that the short is somewhere after the ignition switch but is not in the distributor or the ignitor. All thats left on the circuit is a "noise filter" but we couldn't find that to test it. If its not that, then we are assuming its an actual short in the wire somewhere..



does anyone know where the noise filter is located? have a pic of it?

Thanks!

the injectors and efi main relay run off that fuse as well look under engine control for the first link i gave you

ahh so its back there by the ignitor.. ahhh.. thank you. i will check that out Monday and I will keep you all updated.

if you have any other hints or tips for finding shorts, feel free to let me know, and I love pics!

[Jaws4God]

well i see on the diagram the noise filter.. but when i was out by the car, i looked under the ignitor and I didn't see the filter... anyone got a pic of where its located??

Thanks!

I believe it's a small box bolted to the dr strut tower.
It's tiny. Like 1" x 1". Has 2 wires going into it. It's grounded to the chassis.

It might not be there, I'm not as familiar with the th gens.

Do you have a picture of it? I am trying to find it because its one of the devices thats on the circuit that has short. .i'm hoping thats where the problem is.. cuz if not. i gotta go following wires for a short

Thanks!

[Jaws4God]

Well i found the problem..

when i put my valve cover on, I accidently pinched one of the injector wires.. and when the engine tried to crank, the cam gear exposed the wire and grounded it...

so now its starts up fine.

thank you all for your help!

[Jaws4God]

Well I drove it today for the first time since the starter problem.. but now it wants to stall when I put the clutch it. And I noticed when I shift gears the tach drops quickly.... Any ideas?

When I got to work, I did move the CAI and noticed a change in the Idle RPM's.. so not sure if thats related or not...

Thanks!

did you repair the harness well? with solder etc. does it feel like a misfire? vibrates alot and takes a while to rev up? also check for vacum leaks, maybe pop your stock airbox back in to test.

[Jaws4God]

well my dad and I descovered its the clutch neutral switch.. when that is plugged in and the clutch is depressed.. it almost dies..

so for right now we rigged it up so I can push the button by hand to start.. and then it won't be pressed by the clutch when driving..

just wish i knew why it does that..

[celicast3sgte]

maybe something to do with your cruise control being funky? might be something to look into because the clutch neutral effects the cruise control and a few other functions when depressed.
