1990 Talon Tsi Sputtering problem

[90ttsiawd]

My talon has been hesitant to start the past few weeks but in the end always ended up starting. Up until this week.....Now sometimes i have to push start it because it wont start at all. What could cause this problem? And when it does run it spits and sputters and barely wants to go anywhere when i press the gas, and the exhaust smells like raw gas....What could this be from?! My first thought was fuel pump....but then why would it run rich? I checked to see if i had spark from the wires and i do.....Any ideas would help alot.....

Well it sounds like a boost leak.You have bigger injectors or anything?Because I'm running ~77% duty cycle on my injectors and I'm on the 14b at 15 psi.

No they are stock injectors......It shouldnt be a boost leak because i just checked that and there is no leak.....Any other ideas?

hey man a total shot in the dark but i had similar problems, ended up being me ecu. i took it out and took a good look over it and could see components melting haha. Anyways your not throwing and check engine lights?

this may be out of your reach but maybe your timing is wacked out?, if you have the extra money or know someone with a timing light check the timing, that could also make it run really crappy. it sure as hell is making my car run really screwed up.

heres some links on how to's
