yesterday i noticed my cars idle realy and always in lean, then when i was going into my drive way the car stalled then i got it boosted by anopther car then later at night i went to go get my battery charged at crappy tirr, thne i drove it and it was still running lean and now i went to drive it and its even worse im guessing its a bad alternator thats causing a realy low voltage, which menas the current going to my injectors and fuel pump is low causing my car to run lean?i know ive put up a thousand posts already on my car running lean. sorry if i put this in the worng section i just need the help right now guys.if anyone can give me a call that can help me out th enumber is 416 721 6426 thanks again guys

i think it's possible. break out the multimeter and check fuel pump voltage, alt, and injector volts. based on these reading(if the within spec)you will know if you have a problem or not.
for example,if the injectors are supposed to be 2 volts, and they are getting 1.3v, get concerned.
of course, this is just my opinion.

happy troubleshooting!

I would say yes. When mine crapped out on me, I noticed on the logger, my trims shot up - the ecu was trying to compensate for less fuel coming in cause the pump wasn't getting enough power.
