Changed fuel tank - Now cutting out
« on: August 31, 2010, 06:11:35 pm »
Hi guys, i changed the fuel tank as it was leaking, i have put the new one in today connected all lines back.

Then i come to start it , it starts fine, but after that it cuts out after 30 seconds or so.
like it cant get anymore fuel
i havent taken it for a drive yet, but was wondering if anybody can help?

yeah it sounds like something is not attached somewhere, does it always run for 30 seconds, or just once then dead?

the 2 pipes off the lift pump may be the wrong way around?

Ive checked all the hoses i took off and everything is back on, is it possible i might have trapped some lines inbetween the tank and the floor restricting flow? or could the fuel filter be the probelm.

It cut out 6 times this morning in less then a mile distance.

When i come to start it it takes a few mins to settle, its like i have to keep pumping fuel in, when you turn the ignition on?

Could it be the power output from the car? I know the pumps prime when you turn the key but when the engine is running, they might run off the power produced from the alternator. If the alternator is old it could be that. If its not spinning fast enough at low revs the power output will beless, when you accelerate it spins faster producing a higher output. I have herd of people saying that when you have your headlights on then accelerate a little you can see them get brighter, usually due to alternator.

Just a thought?

If you wanna try another pump to see if your pumps arent gone i have both pumps that i removed a few months ago. Could send them to you to try them out?

It sounds something like my other car did! A renault 19. It would start some times and work just fine and next time it would give me hell and worked like shit! It was the pump at its final moments! But some other weird though just hit me! Well we all know that when you consume fuel air must go in the tank to replace the vacuum! Some tanks have a little hole on the cap witch when clogged gives you similar effects to what you describe, don't know how it's working with the g40 tank but just try running the car without the cap and see how it goes! ( have an extinguisher at hand as well  ;D)

it only primes once! if its already primed it won't do it twice! check the connections to the pump or else it's just dead!
