So I'm having an issue with my truck fuel injected. I was driving it to work and it just randomly shut off on me. Just shut off. No symptoms before other than had issues starting it would crank then pop off and run like a champ. Now that it has been shut off. I have ran test after tests. Swapping parts. I've changed the ICM, crank sensor, both coils, and all wires. And I tested with new spark plug still no spark as I had my girlfriend crank over the motor. So as far as I can go I've done all ignition systems other than the main brain, the ECM. Check engine lights on and cranks like a champ just no spark. So I'm thinking not the ECM because I'm sending and receiving signal to it. I'm about all out of options. And yes all fuses are good. Need some help please!

Hello, I'm Danny.

Have you checked to see what code is showing since check engine light is on? If you don't have access to code reader/scanner your local auto part stores have tool loaner programs and will rent you one. Here is a tutorial showing how to check codes:

After you check get back to us with code(s) number and we can help properly diagnose.Hope this helps and thanks for using 2CarPros.
