I've got an ECM that no longer powers the lift pump on an 02 24v Cummins HO.
I replaced the VP44 and hotwired the aftermarket lift pump (airdog raptor) to test. Manually supplying power to the lift pump and bleeding injectors did the trick, so now I need to wire it in properly.
I read the article on RF noise with aftermarket lift pumps, so I'll modify the harness with a .1 Mfd Orange drop capacitor and modify the pump when I have it out again.
Given that my ECM lift pump circuit is DOA, where should I grab a trigger voltage to engage the lift pump relay?
I am looking at the light green and black wire carrying ignition power at F18 in the first diagram in the engine wiring diagrams post.
Is that the best circuit?
