injector malfunction (non 3800)
I bought a 1997 sunfire gt with the 2.4 twin cam engine for 200 bucks from a friend who got hit by a deer. It ran fine when he parked it about 4 months ago, but when I try to start it now it just turns over and starts up for about 1.5 seconds then immediately suts down everytime. Its getting fuel and spark. There are no blown fuses and there IS gas in it. If you bypass the injectors and pour fuel directly in the TB itll stay running till the fuel burns off. I am suspecting that the engine starts but then get a signal that shuts down the injectors. I couldnt do a proper code scan because the engine wouldnt stay running, but I got a code 200 which corresponds to an 'injector manfunction'. What can cause this? Im trying to get it running so I can sell it for the engine and tranny. From what I can tell this motor is very similar to the 3.4 Grand prix engine, but I dont know if that would make a differance. Its not a 3800 but Im hoping that someone can point me int he right direction.

Not sure what direction to point you in...
The Quads can be a PITA when it comes to those issues...
It seems as if the ICM is doing its job...
But the question is are there any Manufacturer specific codes... Some scan tools will not show these codes...
Being that I am not deep into Quads, its hard for me to point you in any real direction.. They are good engines, but the systems used to operate them was lack luster at best

Thats another thing, did the 97 2.4 use a MAF or was it still speed density?
Can you feather the throttle at all and get it to run?

Um, did these cars come with VATS? IIRC, the keys themselves were the "chip" that we know. My sisters car did the same thing you are describing...and was using a cut key. She went to the factory key, and it started right up.

Ahhh grasshopper...
Not sure about the VATS, but these cars did have a lot of issues with the ignition switch

Theres no VATS, its got the PASSlock system. The gas pedal makes no differance at all. Like I said before, if you pour gas directly into the TB then itll stay running. (maybe a bad idea though lol)
