i'm actually having the same problem, 86 1 ton 22re, and have questions regarding that, on things I tried, hopefully it will help ya troubleshoot your problem. I tried the fuel pump jumper trick to bypass the MAF sensor & others, and it didnt help starting, the only other switch between the fuel pump and engine(when ya do the jumper wire) I believe is the fuel pump relay behind the glove box, which actually turns the fuel pump on when the engine is cranking. I'm thinking I narrowed it down to that relay or the fuel pump. because the way I understand it, that is the purpose of the jumper trick, (to bypass everthing except for that relay & the fuel pump) unless the cold start injector has something to do with it ??? hope that all makes some sense !!
