I have a 97 Chevy 1500 z71 with a 5.7. I was driving home and it just died on me. I have fuel and fire. I re did my timing and changed out the crank shaft sensor. Has a new starter battery and pretty new distributor. I'm out of ideas. Remand motor with 5,000 miles on it. I really need some help on this one and thank you in advance.
