C-12 No Start

Thanks for the info. Crazy he gets the same thing I get when I try and pull the engine codes. It says ecm not present or malfunctioned on the TIM. So I need to look behind the return line for the port to check pressure, is that correct?

So I don't have a J1939 scanner, nor do I have a cruise control button. Is it possible to put power/ground to a ecm pin as if it was a cruise control button to get the ecm to flash the CEL?

Here's my checklist for this Sunday...
- check fuel pressure
- see if anything shows on the rpm gauge while running on ether
- unplug a sensor CEL come on
- check crank/cam sensor
- see if injectors are getting signal

Any other suggestions?

 

Measured the resistance on the primary and secondary timing sensors.

Primary: 114.5
Secondary: 663

I don't have the right fitting to check the fuel pressure at the correct port. I'll get the correct one during the week and try again. Since I had the fitting off of one of the top ports I checked the pressure at that port. It would go to 60 the bounce back to 45.

 

I was able to check the pressure at the correct port, video shows it all. I unplugged random sensors on the engine and the CEL didn't illuminate. Nothing registers on the rpm when cranking or running on ether. Pulled the valve cover and put a tester on the injector to see if there was any pulse. Found a video online of someone doing it, so I figured I'd give it a try. Now what?

 

Any idea why the front cover is dirty compared to the others, just curious.

 

It has 1100 hours and about 7500 miles.
