got a 1988 2wd 2dr 4.0 5 speed, I bought for the cheap, it set for 2 yrs, get it home cranks great but not firing so I put a new crank sensor on still no fire, put a coil on still no fire, change the ecm boom starts right up, idles a little rough but I would to if I set for 2 years, so I put a gallon of racing fuel and a gall of 93 octaine in her, let her idle for about 45 min then drove her around the yard. Acually running real good, shut it down for about 20 min try to start it back up and nothing cranks but no spark out of the coil what should I do next guys ?
