Engine problems-- Please help! - Toyota Nation Forum : Toyota Car and Truck Forums

My brother owns a 95 Celica GT and is having some weird engine problems.
He was driving along one day normally and the engine just cut out on him, no sputtering or stalling, just completely died out but it cranked right back up with no hesitation.

He brought it to a mechanic shop and they ran a diagnostics on it but it didnt spit out any trouble codes. The mechanic recommended that he changed his distributor so he bought a distributor.
After getting back and installing the new distributor it ran fine for about 35-40miles and it started doing the same exact thing again. Dies out, but cranks right back up!

About 3-4 months ago he changed his sparkplugs, sparkplug wires, distributor cap, rotor, and installed a cold-air intake and K&N air filter.

We checked the fuel filter thats under the hood and it was clean.

One odd thing is that if we take off the cold-air intake the engine seems to run fine and doesnt die out. It would normally die within 3-5 minutes. Putting the intake back on and it would die within a few minutes.

We're running out of things to check before we're forced to bring it in to the dealership

Any suggestions and information would be greatly appreciated, thanks!

Errrrr dont wanna state the obvious, but if it runs OK without the cold air kit....dont put it back on

. or check if you havnt disturbed any wires/sensors fitting it.

The intake is fine, the wires are all good.

I been messing around with it and a few times after it dying out, i couldnt crank the car. I turn the key and nothing happens. It would crank back up after waiting a few minutes.

sounds like AFM problems :P

wlel not really

but AFM not liking the new intake.

elwood2 · 09-02-2005, 05:22 PM

Just tried it with the intake off. It's still doing it.

alltracman78 · 09-02-2005, 08:02 PM

The US spec GT doesn't have afm.

Does the cold air intake have a place for the intake temp sensor?
How's engine vaccum?

elwood2 · 09-02-2005, 08:20 PM

Yes, there is a sensor that is "plugged" into the intake pipe. But as i said before, it's doing the same thing with the intake off now.

Go to the wrecking yard & "cheaply" buy a s/h air intake sensor....might fix it

Had brainstorm... Igniter Module !

ignitors not going to shut your car off. usualy the ecu shuts the car off when it gets a bunk signal from the AFM/MAF/MAP sensor, im not sure what your engine uses ive never messed with a 5s. If thats what you have. If the ecu doesnt know whats going on with the air it doesnt know how much fuel to shoot. creating a dangerous condition so it just shuts down. and having removed the intake you probely either unhooked it, didint put the clip in far enough. may have pulled some wires on the clip, didint reinstall it or its just plane broken. check it out

elwood2 · 09-07-2005, 01:47 PM

We've figured it out! The black/red wire that supplies the ignition with fire from the fuseblock is loose. It is loose where it goes right into the fuseblock where the fuse plugs into the prongs. Now we just have to figure out how to repair it

elwood2 · 09-07-2005, 03:52 PM

It turned out that there was a very loose prong for the ignition fuse on the metal strip that supplies the power to the fuses on one side. We just took all the fuses out, pulled the strip out and closed the little tabs on that one prong so the fuse contact would be better and voila!

toyboyracer · 09-07-2005, 04:32 PM

Well how 'bout that....
Nothing at all 2do with the Air Intake after all!
(pull something off n something else craps out)

Now that's NEVER HAPPENED to acar owner b4 has it ?!

RAOTFLMFAO
