I just bought a 94 s10 blazer for a donor engine swap for my 4runner. The engine is a jasper reman and was running perfect about a month ago the fuel spider has been replaced recently also . I went to pick it up and it will not fire just cranks .
I tried starting fluid in the throttle body and still nothing . It has only been driven in and out of the garage for about a year and normally starts right up . I have no experience with the 4.3 so any ideas ? I was thinking rotor and cap ? It has some spark when i cranked it with plug wire off to ground. I need to get this home and start tuning it up before pulling it so any ideas where to start?
