Lifter Pump C2250

[Rawze]

Register your engine ser# on quickserv.com and you can get all diagrams and drawings. Its free.

That intake manifold looks like a CM871, not a CM2250 by the way. Your engine is a CM871.

The pic on the right you circled is the engine brake harness going into the cylinder head.

The lift pump relay and fuse is in the wiring harness just to the right of the ecm.

If the fuel water separator is running dry then it is sucking air somewhere. maybe bad gasket after last filter change?. maybe cracked pick up tube in fuel tank?.. could be a lot of things.



while you are at it...

More than 90% of all de-mandate programs and methods that people come up with are very harmful to the engine over time. Assume yours is bad and eating away at the engine until you get it properly checked out.


Copy the program out of the ecm and e-mail it to me for a review of what someone did. Then you can go from there.
