The fuel pump is giving me some grief.
It caused me to call out the RAC about 18 months ago when the pickup pipe detached itself from the (internal) outlet connector.. so fuel was being sucked up okay but not making it into the outlet pipes and so out of the tank.
A fortnight ago, the same pipe burst (3cm rip
) at the top..
Because of the previous incident (which I thought had repeated itself) I found it and replaced the tubing with some regular fuel injector hose... but again the RAC man came out to drag Tarquini's sorry a*** home...
Anyway... now I think the fuel pump is actually dying... It takes more cranking to get the engine to start when cold.. and I get poor pickup and acceleration off idle. It idles okay and once it's been started once (even if engine is still cold) it's easy to restart.
Theses symptoms were getting worse as the tank became more empty. Filling the tank from 1/4 full alleviated the symptoms quite a bit.. but as the tank started emptying, I could feel the same pattern repeating..
This weekend, the beast started (after a fair bit of cranking) but just wouldn't idle. It runs for about 2 seconds then dies.
I *suspect* the fuel pump.. and I have a new one to go in (waiting for a new level sender to arrive.. mine is "welded" to the pump and won't shift without cracking.. I can tell) but does anyone know how I can prove the pump is any good or not? Is there a test?
The car pulses a signal to it as the engine turns over.. but is is also supposed to do that when I turn the ignition on (mine doesn't.. which may explain why it doesn't catch straight away like it used to)..?
What about the fuel regulator? What does it do and could it be the cause (how can I test)? I'm fixated with the fuel pump because of its "previous" but I'd like to be sure before I hang it..
