Im hesitant to ask but have you tried a new maf?

nm i think it says u tried a few.

 

[BoostJunki3]

yup tried 2 diff new lq4s

 

[BoostJunki3]

aeroforce doesnt even read a maf to be hooked up tho and all wiring is in tact.....

 

[SleeperLS]

Have you checked to make sure none of the wires have fallen/gotten pulled out of the connectors?

 

[BoostJunki3]

yeahp they are all in tact i even circuit and continuity tested them still nothing....one wire has a small crack in the insulation but wire intact and taped been like that forever.

 

[SleeperLS]

I know you stated above, but did the continuity tests come out ok? I remember this problem on my car, ended up being a loose wire at a connector. Also did you check fuses, power, ground?

 

[BoostJunki3]

yeah continuity only checked on the black n pink wires on the maf....the yellow i got nothing but i checked it and its in tact.

make sure you have power/ground at that pink/black wire (check across both KOEO)
TG had an LQ4 fail cause a squirrel farted on it and it took out the fuse that fed it and the AFC
he replaced the fuse and it was allll good
yellow is the signal wire, if it has power you should be able to flip the multimeter over to a Hz measure and see the maf signal.

 

[BoostJunki3]

ok ill check that out tonight.....if i remember right multimeter reads nothing for the yellow wire is there a fuse for this shyt anywhere or not? the aero reads hz for the maf but it hasnt been and the yellow wire is fine i checked it almost all the way through the harness.....ive also noticed the IAC makes a relay sounding clickish noise with ign on....if i unplug the map it stops or up plug the IAC.....it constantly clicks and something else sounds like its energizing......your james right? i should just get the car towed to you so you can work the magic on it lol

 

[BoostJunki3]

ok so the pink n black wires have contunuity but show no voltage.....black and yellow only show 5v and when i test the leads seperately.....yellow to the read lead and black to batt ground i only get 5v.....but if i hook up 12v batt to the red lead and black wire to the black lead i get 14.5v......is the yellow wire bad then? i traced it and cant find anything wrong with it.

 

[Turbocharged400sbc]

check your fuses, pink should have voltage. im too tired to look up which fuse but look for ENG or PCM in the labeling or just run through em all with a test light/voltmeter or pull and inspect...your old maf prob blew it

 

[BoostJunki3]

yep found it.....fuse 33 i think it was ign sen or something wow 1 new maf and oxygen sensor later i find a blown fuse haha oh well thanks man.

 

[Turbocharged400sbc]

[BoostJunki3]

James, i give you a lot of shit, but you are probably the #1 person for diagnosing problems. Sometimes you think just a tad big outside the box, but i knew you would be able to help him out on this. I am right now. I give you a
