Help.... Fuel pump relay or CPS
Ok... car wouldn't start out of the blue. I get codes off durametric , but didn't have check engine light on at any time. My point is ... I'm not sure how old they are.
So ... initially I had Fuel pump relay, CPS bank 2 , and a few others. I clear all, turn over a few times and get Fuel pump relay. So jump the relay ...the car starts fine. I order the one that I can get the fastest....KAE.
Car doesn't start after install. I get the same code ... fuel pump relay. I jump it again... car runs perfect and zero code or noise.
Is it Another issue or possibly the new relay is bad??? Thoughts?
Is there a way to test for a signal to the relay??

Ok... I ran the engine and checked CP, and they are pretty solid with similar fluctuations when reeved. Cam position deviation -7.23 and -5.76
Ps... Porsche makes a great jumper relay.
