    Fuel pump pressure f7p

    Just finished putting my car together after the head killed itself

    went to fire it up and it started straight up but sounded funny when to restart it for a inspection it would not fire, the fuel pump primes then drops off, it primes upto about 4 bar not 3? then drops off to 0 meaning no pressure what could the prob be as ive not changed anything after i took it apart and rebuilt it mmmmmmmm ?

    If it's adaptronic then the fuel pump signal is only set to 10sec's I think the max you can have it on prime is 30secs.

    Once the car is running it will run constantly.

    Found the main problem ! The crankshaft sensor had somehow rubbed on the flywheel and broke/cracked the sensor but i had a old spare

    It starts now! Just need to fix the fuel pump bit as i wired it straight into the mains to get it to run.
