Hey there. So my problem is that I left the talon in the garage for a month and when i went to start it again it wouldnt run. She turns over and fires but wont stay running.

Spark is fine, i replaced the fuel filter a few months ago, fuel pump relay is working. I heard it could be the Cam angle sensor or crank sensor. My Datalogger shows that the TDC is moving so would that rule out the CAS? Any thoughts would be appreciated. Thanks
 
So i replaced the CAS with a known working one. Nothing changed. Since i recalled that it was raining really hard one of the last days that i drove the car i thought maybe my GM MAF was damaged by water because my intake is so low to the ground so I replaced that, and still the same. Thought id make sure the timing belt was in good shape. It is.

Because of my work schedule I dont get more then a few mins a day to work on this before i go to work again 7 days a week. I would love to get this thing back on the road before winter hits again.
 
Now long has it been sitting and how old is the gas in it? Might be your only problem, bad gas. Drain the old refill and try again.
thanks for the reply. Its only been sitting for about a month and a half.[DOUBLEPOST=1410039278][/DOUBLEPOST]... replaced the coil packs even though the cars not throwing out any errors because when it fires up and dies it act similar to a burnt out coil pack. No dice.

replaced the ECU with a spare, no dice. On a side note one of my spare ECU's makes some cruppy clicking and whining noises when its plugged in. Doesnt smell bad and doesnt look any worse inside then the rest of them. Anyone have an opinion on that?

Ive never had an issue with getting bad fuel before, nor have I drained a tank. But I noticed the tank is 90% full so I must have had filled it up just before it happened. Would adding additives like water treatment and stuff work just aswell?

Im about to stab myself in the eyeball with a spoon... soooooo some input would be great.
