3406e 5ek no start

I had a driver sit beside the road for several hours on Friday because the ECM wire came loose from the battery and shut the truck down. It was just a sudden engine light flashing and it shut him down. This sounds like a similar scenario.

 

Check your 12v pin for ignition on to ecm? Those go bad...

Though with ecm power im assuming thats good

 

Hey. We’re you able to get it figured out?

 

I have the same exact problem. To the T. Did you figure it out?

 

Anyone tried to replaced the timing sensor ?

 

Yes, wish it was as simple as that. Change sensor twice, reman ecm, overlayed wiring, watched waves with oscilloscope, had butt-load of mechanics/techs/engineers call and advise me and remoted in just to tell me what i already knew or already done. Bro im having dreams of this truck no joke. Im waiting on some components (stupid radioshack had to shut down) to build a signal generator and see what happens with that. Anything use lful would be IMMENSELY appreciated.

 

Take a noid light and hook it to an injector solenoid with jumper wires then crank it. That will verify if it’s electrical or a mechanical issue.

I get that you found all those issues with around the ECM. However it seems you’ve fixed all that and it still has a no start condition so it’s possible that all those issues were not your problem and you need to look elsewhere
