kenclarke Posted August 2, 2009 Author Report Posted August 2, 2009 PD engines have a low pressure electric fuel pump located in the fuel tank. So advice for these engines to check fuse,relay applies. have found the connection to the solenoid 12v comes on briefly when ignition is switched on then goes off there is no 12v feed when engine is being cranked THis sounds like immobiliser problem - 1st check, check for PATS chip in key, this often drop out when the key is opened to change battery etc.chip is in key, if i put a live feed from battery to stop solenoid and crank engine should i start to get fuel at top of injectors Quote
seatkid Posted August 2, 2009 Report Posted August 2, 2009 Maybe. :rolleyes: I think the fuel distributor pump is capable of cutting fuel delivery to zero as well. Try it and see. IIRC imobilser blocking usually means you can start the engine and it cuts out 2 seconds later..... Quote

IIRC imobilser blocking usually means you can start the engine and it cuts out 2 seconds later.....i am getting fuel to the pump from the filter but nothing coming out of lines at injector, i have put a +12v feed to stop solenoid, how long should i need to crank before i see any fuel?

cyborg Posted August 2, 2009 Report Posted August 2, 2009 If youve check your fuel pressure pre jets thenI think its got to the fuel pressure regulator rare one if iit though Quote
sepulchrave Posted August 2, 2009 Report Posted August 2, 2009 have found the connection to the solenoid 12v comes on briefly when ignition is switched on then goes off there is no 12v feed when engine is being cranked You definitely have an immobiliser issue, if you put a temporary 12v feed to the solenoid and crank the engine you should get fuel after a while and it should definitely run, suggest you take it for a drag rather than flatten the battery to do this.
