I have a 110 td5 that turns over but doesn't start. Ran great previously but not today. Cannot hear the fuel pump priming, but it was replaced 2 years ago because it was antisocially noisy. Pulled off the return fuel pipe off the cooler and got no fuel. Sprayed engine start up the intake and it fired up briefly. Removed the pump relay and it metered ok. Bypassed the relay with wire and fuel flowed but still wouldn't start. Any ideas?
Hi, have checked all the fuses and my pump relay on my 1999 is green and under the dash. opened up the relay and tested its operation. I bypassed the contacts and fuel seemed to flow out of the disconnected pipe. But I cannot hear the pump running or get the car started.

Tested all the relays all seemed OK, replaced then and touch wood no issues since.

Hi Mcclegend, you say tested all relays and then replaced them, Did you replace all the relays or just the fuel pump relay?
Does this mean it's been stood two years? How long ago did it run properly?
I'm thinking of simple stuff like congealed fuel blocking pipes, fuel filter, blocked air filter, etc

All of them, 2 of them were £4 each and the other smaller one was £11 or something like that.
I was gone test them with a variable power supply to see if the voltage drop from the battery when the start motor kicks in is enough for the relay contact to drop but I can't find my power supply.

I did a static test with a multimeter and not with any load etc. will order new ones anyway.
The car is used most days and ran fine apart from being a bit kanagroo ish at slow speeds.The car had done over 220,000 miles without many issues.
I have taken the cover off the relay and it clicks in when the ignition is turned on. Should you hear the fuel pump priming? The old pump changed 2 years and 20k miles ago was very noisy. Haven't really heard or noticed the new pump since. When the pump was changed there was some oil in the tank. I bought some injector seals and washers but haven't got around to changing them. Could this cause premature pump wear etc.
