Title: fuel starvation
Post by: caveman on 06 May 2015, 18:54:49
i have recently had to call out the rac to my omega twice for fuel starvation problems
they got the car running and had no problems until i stopped and tried to restart at which point it ran for about 5 seconds and cut out
i had no problems with the car between break downs as it ran for about 30 mins
someone seems to have bypassed the fuel filter with a sealey hand primer
any ideas would be very welcome
cheers

Assuming the following:

1. It's petrol.
2. It's on level ground.
3. It has over 1/4 tank of petrol in it.
4. That the RAC bloke is a total moron.

... then my money is on it being the Crank Sensor.

Replace with a genuine brand new one, purchased from a genuine Vauxhall dealer that you genuinely have to walk into to pay for/collect.

Of course, if 2. and 3. don't apply, then put at least 4 GALLONS of fuel in and try again.

If neither of those work then you're looking at either the fuel pump relay or the fuel pump.

If my first two suggestions don't work, then ive the bottom of the fuel tank a whack whilst someone else cranks it. If it then fires, the fuel pump is donald, if it doesn't then the relay is... (it's one of the two purple relays in the engine bay fuse box) :y

i know this will sound daft but here goes
i found a leak from pipe off side of fuel pump upto injectors and have replaced but whilst down there asked about buying a fuel pump relay and was told they dont have them its an ecu that i need
have seen them being sold on ebay and im easily confused lol and if there is a fuel relay which one is it as been told pink/purple and i dont have any that colour
cheers again

cured by just checking problems mentioned to be honest...someone mentioned relays which are just above where i found the leak...gave them a good clean as spray had got inside box and when took off the relay box from the fuse box to get inside it i noticed a bolt sticking out further than others on pump just below it....having tightened it and then tested i could see a second leak from pipe under the relay box....replaced all pipes for a tenner and the relay was toast as well.....garages wanted 50 quid just to look then a small fortune to replace whole pump and ecu....car is not worth alot but is my only run around at the moment and without the input from members would have cost me a fortune
cheers again guys
