hey, needin some help, the cossie decided he wasn't going to start on thursday so had a quick look and put it down to the engine not gettin fuel. so i started to day by checking the fuel pump fuse its ok, i then checked the fuel pump relay and again its ok to, so i thought it was the pump i've dropped the tank and put a direct supply on the pump bt its fine as well. what i've found is the connector at the back bumper there is no supply to it. oh i've also checked the fuel cut off sw its ok to.

really need some help please
all ideas welcome.

cheers

ok looked at it a bit more its pin 28 on the ecu and thats whats stopping the fuel pump starting. anyone know why this would be?? could it be a faulty sensor??

cheers

 

the ecu starts the fuel pump when the engine is turned on,
so does the fuel pump prime when the ignition is turned on?,
check the cps,crank position sensor.front pully by the radiator.
and the sensor in the distributor.you can buy these cheap from matt lewis on here or ebay.

 

Hi no it's not priming when i turn the ignition on i'll have a look at them tonight cheers. A mate who has owned cossie's think's it could be the map sensor any chance it could be that. Prior to it not running at all every now and then it would play up would only boost to 0.3bar and when you hit 4k it would cough like a miss fire. He think's it was the map sensor giving up. Cheers for your help.

 

Crank position sensor i'd say.

 

as above, the cps should send a signal to ecu and when it picks up over 250rpm (iirc) it then sends a signal from ecu to switch fuel pump relay on.

 

Cheers dude's i'll try that there only 25 sheet's so i'll get one and see if that sort's it. This YB thing is new to me. Give me a Peugeot engine and i'm sorted. but cheers again for the help

 

Where are you located, are you in Keith or is that a different keith to what I'm thinking??? I have a spare CPS if you want to borrow it to give it a try.

 

hey yeah i'm in keith outside aberdeen. working in cults at the monent, would be ace to get a wee shot to see if that's the problem think it is cause i Took out my cps tonight one it was covered in oil and crap but the outer pvc had worn through so i think it's been grounding out on the block. hope that's the prob.

 

No worries I'll PM u my number.

 

Cool cheers dude.

 

Well thank's everyone for your help. Rog you the most for giving me a loan of the cps. Popped it in and the fuel pump relay pop back into life. Got a new one ordered so hopefully the escos will be back on the road next week. So cheers again everyone.
