405TD Starting problem Jul 2, 2008 9:35:59 GMT

In May i left my 405 1.9 TD sat for a week while i was away. When i came back it would not start, the engine turned over fine but it wasn't even trying to fire up. I primed the fuel system using the squidgy rubber pump and it fired up no problem. The car hasn't been left more than a couple of days since and has been fine with no starting or running problems until last night. The car has just been sat for 4 days and when i came to use it last night i had the same problem, i primed the fuel system and it started fine and it started fine this morning. I am thinking that air is getting in somewhere under the bonnet and allowing the diesel to run back into the tank, but i don't know where and i can't see any leaks. Has anyone else had this problem on the peugeot 1.9 TD engine?

Cheers
Jon

Yes, common problem. You need to methodically check every hose and connection from the injection pump to the tank. A temporary transparent fuel hose is useful to see any air bubbles going into the pump. Note there is a fuel heater on the water pump manifold low down at the back of the engine. It can get covered in engine oil, damaging the fuel hoses. You don't see fuel leaks because the fuel is normally under vacuum. The air gets sucked into the leaks.

Hello there, how did you get on with this out of interest as my car (1994 405 TD) has exactly the same problem. I already replaced all the injector leakoff hoses, no difference. Even tried pressurising the fuel tank with air to check for fuel leaking out anywhere.
