ASH3 - 25/3/15 at 06:26 AM

Hi guys I have a non start issue, fuel pump in the tank will not run it has 10.6volts at the
multiplug and an earth but wont run if I back pin the plug and put 12v to it the pump will run. Also scanner
showed crankshaft position sensor was down new one fitted it ran for a mile towed it home
only to find this no fuel pressure issue scanner says fuel pressure sensor but till I can sort
the tank pump out im lost...any ideas chaps

Id be checking the fuel pump relay. Maybe swap that first. Then check the feed for the relay, just trace it all back.

The pressure fault is probably because the pump isn't running and it's not seeing fuel pressure as it expects.

Ive swopped the relay but still only get 10.8volt at the pump surely it should run without me
Putting 12v to it...
