I've spent hours reading all the posts. I see people post in threads with my same symptoms but no solution. Fuel pump will prime but not get power when cranking.
I have to crank the car over until the oil pressure back up powers the pump. I changed the fuel pump relay, no difference. The fuel pump will prime and I get pressure in the rail the first time I turn the key, subsequent key cycles will not prime unless I wait for maybe 20 seconds. When cranking the pump does not get power/zero fuel pressure until the oil pressure backup kicks in. Once I get oil pressure it fires right up, I can shut it off and it will crank and fire easily. Until I let it sit and lose oil pressure.
I know the cam sensor is working, runs poorly and engine light comes on if I unplug it while engine is running. I was going to check the cam sensor and timing next, would this cause my problem?
Or bad ecm?
