Omega General Help / Re: Car not starting. Fuel pump only getting 9.5v on crank nover

« on: 25 June 2017, 18:50:34 »

When the ignition was first turned on I had 12v briefly which then reduced to zero. When I was cranking over voltage went back up to 9.5v and remained there whilst cranking. I wondered if this was due to the demand on the battery. Would 9.5v be enough to get some pumping of fuel?
I think I'll remove pump and see if a 12v supply runs it.

Omega General Help / Car not starting. Fuel pump only getting 9.5v on crank nover

Last chance for the old girl.

I have been having problems starting the car on petrol but can hard start on gas. I have tested the purple relays which both seem to be working fine. Ie. continuity across the small spades and good closure on supplying 12v to create continuity across the large spades.
I have fitted a new fuel pump as RAC told me that was the issue. However, the car still refuses to start.
I have disconnected at fuel feed manifold, I am assuming the right hand larger pipe is the feed? On crank over no petrol is coming out. The voltage at the pump is about 9.5v on crank over. Is this correct? If so then i guess the new pump is faulty?

Nah. More welding needed. That's that then. On egay she goes, I will miss her. Thanks everyone for all your help but this car is trying to tell me something.

Car starting on gas again. But wont run on petrol.
Is it possible that this might be a crank sensor issue even though it will run on gas? I'm thinking not as surely all the crank sensor gives is a pulse?
MOT tomorrow. I'd better not run out of gas
Not sure where to go after that. I suppose that she might be worth something with a years ticket.

Put more fuel in. 1/2 full. Still no joy. Damn! Car not starting on gas now. Had enough for today. Battery on charge. Hope to get it started tomorrow but think this car is trying to tell me something.

Both behaving the same 12v down to zero.

Will swap them over and report back.

So is it right that you get 12v on turning on the ignition which then reduces almost immediately?

Do you mean the purple 80a fuses on top of the battery? I have checked these for continuity and they are fine. Petrol tank is 3/8 full and car is on the flat. Will the extra fuel help?

New pump hasn't solved this. When I turn ignition on there is briefly 12v at external connector for the pump which then dies away. Pump is not pumping at all. I can hard start on gas but when I try to turn back to petrol the stag system will not allow it.
Presumably, the fact that the car starts on gas rules out crank sensor?
The pump fuse is fine.

Wet and dry and then a plastic polish. Meigars rings a bell.

Nope! Car wouldn't start today. Fuel pump not working. Car fired up with easy start after the air filter and then conked out. Put 12v to the pump from the battery, no noise. Am ordering one

My car was having no start issues. I put a new fuel filter on and the improvement is remarkable. Just a thought.
