I just purchased a 93 S10 with 81K. Got it home to pamper it a little with some TLC. After sitting for about 4 hours, it would not start. Cranked fine but no spark or fuel at the injectors. Later next day, first try it started normal. Moved it, started it a couple more times all was normal. An hour later wouldn't start, again no spark no fuel. Anyone have a similiar experience? Any suggestions?
