Did a bit of investigating as to why fuel not getting through and car would not start. Unscrewed the fuel banjo on the FIP. No fuel when cranking.
Checked fuse 39 OK, relay RL12 tested OK. Ran a lead from battery +ve to pin 87? under RL12, I think it was. The in tank pump would still not run.
Opened the "hatch" in the boot to get at the pump. Unplugged the connector and plugged in my spare pump just lying on the carpet to test it. The new unconnected pump ran immediately the ignition was turned on. Surprised, I thought it only ran when engine was turning over? Earlier cars pump just when glow plugs come on.
Anyway the problem now confirmed as a duff intank pump (Britpart). Been in less than 5 years. Original factory one was in for 15 years.
Unscrewed fuel unions and loosed the ring holding the sender unit in. Lifted the sender unit out and found the rubber tank seal had slipped down inside the tank and was caught around the base of the sender. It had swelled up to twice its normal size in the diesel. Explains why my fuel gauge sticks sometimes. Ordered new tank seal.
