Archived Truck will not start

[msperos]

My 2002 3500 at work died on ran like junk on Friday and now will not start. Here are the Codes
P1693 Companion no biggie
P0370
P1690

I have seen others get these codes but no definitive answer on a fix. I had the VP44 go out about 10,000 miles ago while still under warranty. It also has the in tank lift pump now.

I will check the connections today. Any thoughts? is it just the CKP or another VP44?

sure the lift pump didn't take a crap? do you have a fuel pressure guage installed?

Lift Pump is good. It has the intank and has good pressure. Just got it on the lift to start checking connectors and grounds

Is the injection pump RPM signal is missing,The 1690 is ECM rpm does not agree with injection pump RPM. since the PO370 is before the P1690 it probably an injection pump problem. I'd first check power and ground at the injection pump first that could interfer with the RPM signal.
