heath robinson Posted March 6, 2014 Share Posted March 6, 2014 Basically, I ran the truck for a few miles with the earth to the rear of the truck, including the in-tank pump, disconnected. For "disconnected" read "severed by flailing propshaft". The truck ran fine all the way home, but (obviously) wouldn't start the next time I tried it. After reconnecting the earths, it made a noise halfway between a toddler humming through a straw into Ribena, and someone slowly killing a pig. I did a bit of reading, and came to the conclusion that this was it's priming noise, so followed the advise and turned the key to pos II, pushed the accelerator down 5 times within 15 secs (which tells the pump to run for longer to purge air), cranked for about 10-15 secs, and it ran. However, the squealing toddler-pig was still living in the tank, whether or not the engine is running, and it won't restart after being left over night. Have I mullered the pump somehow, by pulling fuel past it when it was unpowered? Any suggestions of a cheap place to get a new one if so?

V8 Freak Posted March 6, 2014 Share Posted March 6, 2014 Mr Robinson Sir.... My pump was quite loud some time ago and I took advice and changed my fuel filter. Certainly quitened the pump down and it then ran normal... Also... The prime sequence.... I assume you are letting the sequence run until complete before trying to start the car engine....

Tanuki Posted March 7, 2014 Share Posted March 7, 2014 Change the fuel-filter - something nasty and slimy may have been shaken loose from the inside of the tank during your prop-flailing incident, and found its way through into the filter. The TD5 in-tank pump is actually a 2-stage thing - the low-pressure side lifts fuel from the tank and feeds it forward to the filter for filtering/de-aeration - then it goes back for a second time through the pump which boosts the pressure feeds it at high pressure forwards to the engine. When I changed my filter I needed to run the purge-cycle several times to expel the trapped wind before the whining-and-bubbling finally quietened down.

carlosbeldia Posted March 7, 2014 Share Posted March 7, 2014 I had same problem with my car and did 2 things I found in Argentina's forum: took out the air bleed valve (in fuel filter housing) and put a hose between air bleed lead in the fuel pump and the fuel.... never have made another sound and never have failed again in the morning...

heath robinson Posted March 10, 2014 Author Share Posted March 10, 2014 Cheers guys. It turns out that the filter was so blocked that the priming cycle only lasted two or three goes. New filter, and about 20 priming cycles = working truck, and quiet pump. Cheers guys! Quote Link to comment Share on other sites More sharing options...
steve200TDi Posted March 10, 2014 Share Posted March 10, 2014 Yes, I got my truck fired up again last weekend after taking the cylinder head off and it took forever to prime and start! I don't know why they take so long! Steve Quote Link to comment Share on other sites More sharing options...
