But when i put current to the relay points the pump works and she still only stars but dies. Glowplugs not working off key but it could be a relay.
As above, it's not an immobiliser issue as that would prevent it firing at all.I'd start with what doesn't work, like the in-tank punp.
The immobiliser should stop all fuel getting past the FIP so I wouldn't expect it to fire at all. If it does, even for a short time, then fuel must have got through somehow. Typically the diesel turns over but doesn't fire when it loses sync.
Fuel pump on the diesel only runs under certain conditions which vary according to year.I get that. I have 12 v at feed to relay but not out. What would cause this
What year is your car? On early cars the pump only runs whist cranking or when the engine is running.Fuel pump relay yes. one contact has power but not the other. if i bridge the 2 i get fuel but she still dies after starting. So why no power out to pump, Could it be the inertia switch which i have pressed but could it be faulty
The glow plug relay?I get that. I have 12 v at feed to relay but not out. What would cause this
I think he was talking about the fuel pump relay?The glow plug relay?
One side will be powered when needed and the other maybe a live feed to the plugs that is connected from within the relay. You can check a relay with a 12v battery and a DVM. Power the relay to switch and check continuity on the other two connectors.
A relay can work but the connecting surface that makes the circuit can burn inside of it. Everytime the contacts inside the relay open a small particle of the surface is pulled away and eventually leaves a damaged contact surface.
Do you have another relay you can try?
Have you checked to see if there is current at a glow plug?
Thanks Keith, I'm confusedI think he was talking about the fuel pump relay?

Sorrry it is the relay for the electric fuel pump. I also have a glow plug issue which has been wired direct to battery for test purpose but will be removing the inlet on the weekend to access fip and glowplugs. I believe the relay for that is in the box behind the battery. not sure which one or if there is only 1 cant remember but will be checking. My real question has been that why do i only have power into pump relay and not out. I will be checking the inertia switch as well. Beyond that i am puzzledThe glow plug relay?

Don't apologise matey, have you tried another relay in it is place to rule it out?Sorrry it is the relay for the electric fuel pump.

The is no "kick in kick out" there are either 2 or 3 circuits that can energise the pump.Yeah it kicks in until pressure to fip then turns off until start then kicks on again when running i believe
