i have a my99 uk turbo and was driving it home tonight and stopped at some lights.pulled away changed to second gear and accelerated gently and the engine died very slowly until it stalled lukily i had pulled into a lay by,it wont restart it turns over as normal and seems to want to start and sometimes it does but only idles at 2-300rpm then dies after 5 seconds or so and if you accelerate when it is idling it dies straight away and it wont start again its late know any ideas what to look for or test in the morning thanks in advance guys

 

can you hear the fuel pump priming? sounds to me to be a lack of fuel.

Check the pump connector under the rear seat hasnt burnt out.

 

done the cel check its two fast flashes followed by 3 quick one i presume this is 23 to which is the maf sensor.i have also checked the fuel pump doesnt seem to be running disconnected the pipe after the filter and no petrol is coming out is this a pump problem then or maf

 

reset the ecu and the fault code has gone,still not getting any fuel through to the filter so presuming its pump or relay related any ideas how i check both i have the back seat out.

 

fuel pump is under an inspection panel driverside of boot floor. Its easier to get to from inside the car with the rear seat removed(back of seat as well as base) Then check for a 12 volt feed when ignition is turned on which will dissapear. then should return when cranking. As ive already said check the connection under the rear seat? its common they burn out.

 

right then
i have identified that there is no feed to the pump its only 4v and doesnt change when cranking.found the green fuel pump relay and it has 12v over two of its terminals with the ignition on(relay not connected) and with the relay connected we get 12v over 3 of the terminals but still only 4v at the pump connection under the seat does this now sound like its an immobiliser fault cos my head is fried and i feel like throwing a match in the tank

 

sounds like a wire broken between the relay and the pump,Unless the ecu alters the votage at pump to slow it down. that i cant answer.


Try connecting the pump direct to a 12v feed to see if it runs. Maybe the pump is u/s. I'd still expect it to do something even with 4volts

 

turbotits
thanks for your help
the pump runs fine with its own 12v supply and the car starts and runs just doesnt do anything with the 4v supply better get an auto electrician in i think
