Fuel Pump failed
« on: 14 July 2010, 10:47:11 »
Hi Gents

My miggie has just given up the ghost.

Its a 2.2 LPG 2003 118k.   Runs ok on LPG but now nothing on petrol.

AA says the fuel pump is not working ?

Thoughts ?

Is it difficult to change  as I cannot find a how to ?

Thanks in advance.

The fuse was physically checked or did he just whack a meter on the pump connector

Got a pump and filter and a willing mate.

Took cover off tank and checked again and we can definitely hear the pump so abandoned the job.  Runs on gas but not petrol .. it just dies as if no fuel..

messing about and it started to run ok on petrol just left it idling on petrol nice and smooth and then it just switched back to really lumpy and stalled.

Help me !!!!!!!!!!!!!!! beginning to hate the miggie ( Love her really)

If it runs on LPG, why are you worried about Petrol?  ::)

When was the fuel filter last changed - might be blocked ??

Are all the fuel lines ok - its not sucking in air at all ??

Have you tried disconnecting a fuel pipe and using the pump to pump through .. that would check the the pump is picking up fuel OK.

Check the Fuel Pressure Regulator .. it might be sticking shut.

about all I can think of right now ....

UPDATE

replaced fuel pump and filter now ticking over but sometimes dying and when trying to drive it feels like i am towing a elephant !!!

LPG still ok. 

Could it be too much REDEX as I popped some in thinking it would help ??

Thanks anyone who can help

Sorry, good point, sounds like the pump was fine then. Is it worth giving all the fuel lines a blast of compressed air to make sure they are clear?
