    Seems like I get no signal on the yellow wire fromt he MAF and my MAF reads 0. I tried a new MAF and same thing. I'm guessing it must be the wire so I wanted to bypass it to test. What pins on the PCM are for the MAF

    IGN 1 fuse is probably blown, it is in the under hood fuse block.

    hey thanks. I wiill check and report back...I also managed to find what pin the MAF is on the PCM...so if the fuse fails I'll go after a direct connection

    I re-wired the MAF and replaced IGn 1 + UH fuse (15A) which was blown...works like its supposed to. Hope it doesn't blow again as that might suggest an underlying problem...Thank You!

    Mine was blown, I replaced the maf and it has not blown again. I thought it was a maf issue, untill I looked in the repair manual.
