Ok Ive been going through all sorts of post on here and found alot of very useful info on here, so for that thank you all. I bought my wife a 1990 Sidekick and after a few days I knew I would have to have one. I bought 3 more Sammys after that one is a 1986 4x4 the other is a 1990 2 wheel drive and a 1991 4x4 for parts. Ok enough with the introduction, my question is one, where is good place to find simple parts like a starter or other misc. parts other than autozone. The 86' runs great but the 1990 has no spark but does turn over. How can I test the P.C.M or the control module or the ignitor or the coil to tell where the faulty part is? I know this is kind of a duh type question but any info would be great.
