I'm hoping someone can help me. I was driving my truck, all was going good. Then it jerked and tried to stall. I engaged the clutch , gave it some gas and it cleared up....for about 20 seconds. It then stalled and won't start. I now has new plugs, wires, cap, rotor and coil. I even replaced the computer. No go. Won't start. Cranks but won't fire. Any ideas on what I'm missing? Thanks in advance

 

Have you verified that you don't have spark? Do you have fuel pressure?

 

Thank you for getting back with me. Yes to both. It was suggested that it might be the spark modulator. Getting one first thing in the morning. I was told that they go bad often.

 

It was the spark modulator. She's running good again. Thanks everyone for your help!
