stockgp Posted April 11, 2005 Report Share Posted April 11, 2005 93 3.1/4t60e. i'm trying to figure out why my car won't run for more thatn a minute the other day and while coding it, i hear a weird noise from the engine bay. i took the fan relays out so i didn't drain my battery and that's when i heard it. it's coming from under the plenum and it sounds like a mini air compressor. also i keer getting the code for the map sensor, but i can't find a vacuum leak anywhere. any ideas?

digitaloutsider Posted April 11, 2005 Report Share Posted April 11, 2005 My car actually has a mini air compressor under the hood.. But really, I have no idea. When you were trying to pull codes, you didn't have the engine on, did you? Quote Link to comment Share on other sites More sharing options...
rudefyet Posted April 11, 2005 Report Share Posted April 11, 2005 speaking of air compressors my grandma's Lincoln scared the shit out of me today. I was in the driveway prying on my rear brakes when i hear a buzzing sound come from her car and the damn thing levels out. Damn air supsension As for your problem...only thing only the plenum that i could see causing that would be the fuel rail/injectors, maybe that buzzing is the fuel pressure escaping when you turn the key to check codes Quote Link to comment Share on other sites More sharing options...
stockgp Posted April 11, 2005 Author Report Share Posted April 11, 2005 idk. this is getting frustrating, though. after i switched my new battery in, i couldn't get the car to start. then when i put the charger on i got the same thing. the charger clamps did get really hot, though. and for some reason i'm not getting any codes now. as for the weird sound, i was thinking maybe a fuel injector was constantly pulsing? if i put my hand on the plenum i can feel it, so i know it's directly under there or attached to it. i'm trying to get it to run long enough to do an idle relearn, but no luck so far. any other ideas? i'm desperate Quote Link to comment Share on other sites More sharing options...

RareGMFan Posted April 12, 2005 Report Share Posted April 12, 2005 Hmmm....when I try pulling the codes on my cars, the fan will usually come on. Don't know about anything other then that, though. Quote Link to comment Share on other sites More sharing options...
