3.0d only priming intermittently

[Kshamm]

Hi Ausbmx. I’m sorry to say I never did. I ended up selling the beast to a guy that was pretty confident he would fix it straight away. He too has still
Not fixed it. My gut feeling in the end after all of my research and diagnostics was that the ecu had a gremlin and it was not worth the time
Or cost in repairing it hoping that it would work. Sorry I couldn’t share a more helpful response.

Ahhh damn! If you don't mind, can you remember all the things you changed/tried to resolve it? I get the feeling that it is likely electrical/ECU related too.

Next on my list are probably:
1: New fuel regulator on the back of the rail
2: Replace all relays, even if they test out okay.
3: Flow control valve on back of HPFP.
4: Go to the wreckers/junkyard and get another ECU and see what happens...

To summarize my issue first.

Car would not prime on turn the key to position 2, I would turn back and forth between position 1 and 2 until I could here the pump prime and then I knew it was going to start, this happen once or two a week in the beginning until eventually it would not prime at all.
It was throwing multiple codes but none that really helped


Tasks I tried to fix the beast ( If I think of anything else I did I will reply again)

New fuel rail sensor ( front of engine)
Checked/swapped every single related relay/fuse – visually and with a multimeter
New in tank fuel pump
New battery
New fuel filter
Removed/cleaned the injectors


Things that were next on my list before I decided to cut my loses



New fuel pump regulator ( the one that is fitted to the HP fuel pump)
A packet of matches ( to burn it to the ground)


Items that had been suggested to change/check but I never got to

New key


Like I said though, my gut feel was it was ECU related and I just was not going to keep throw money at it in the name of hope.
