1994 Lexus GS300 Q&A

1994 Lexus GS300 Question: My Lexus will not stay started. I replaced the fuel pump & fuel filter.

Tried changing the battery and still will not stay cranked. Its been siting for a month now. Do anyone have an idea on what the problem could be? Please help me! -
Answer 1
Was the battery dead at the first attempt to start? Can you force it to run by using gas pedal? -
Comment 1
Yes the battery was dead and yes once its jumped I keep giving it gas but cuts back off. Could it be the IAC valve, or a relay? -
Comment 2
Was thinking it may need to relearn idle straregy. Try to keep it running as long as you can to see if it will ever idle correctly. May take a few minutes! -
