Well I got the Bosch fuel pressure solenoid and installed it. No change to my symptoms. I will get the scanner on it and crank again soon. Based on the original codes, I am thinking maybe there must be air getting into the system and I just can’t find it. I should’ve replaced the fuel pressure sensor as well, that maybe the only one I’ve yet to replace on the engine.
I also did a quick look but didn’t notice anything behind the fuel filter mounting bracket. Starting to get frustrated with the whole thing.
When cranking, it does make an odd sound about every second as if maybe it wants to fire but won’t. Not sure if that means anything. Having to wait a week to get the next part to try is really getting old as well
I feel your pain.
I went as far as to replace the CP3 !
Got some great advice from ww , tested that the injectors were getting a signal, checked the pressure sensor output signal while cranking, it changed a little, but stayed at about the no crank value. Took the overflow hose off the fitting at the end of the rail & cranked, fuel came out the fitting even when the power connector was removed! So, after nearly a year of issues a problem was found. I am waiting for a new solenoid to arrive. Covering the end of the solenoid with foil & tried again, got good voltage output, up to 1.5v & no overflow. I stopped cranking as I did not want to have the signal go too high.
Hope to have the new solenoid next week.
Have you tested to see if the injectors are getting a signal when cranking? I used a simple small LED light to see this.
If you have good cranking fuel pressure signal & power to the injectors, it should start. It may need some starter fluid to help the first time.
You can put clear tube between the filter & the CP3 to see if you have air in the fuel.
Good Luck !!
