No prming of Fuel pump

[drakon]

Had a problem last night were I pulled up to my mates house to check out some work he had done. Turned car off and went to go start again. All crank but no start. After fiddling with the Cam and crank sensors and having no luck ended giving up and was going to stay at his house the night and deal with in the morning.

By chance I went down and check if it would start 2 hours later and it did. So i quickly got my girls in the car and got car home.

Now the car wont start at all. I have pulled of the lines to the fuel filter and cranked engine. No fuel comes out (there is half a tank left in car).

Also my brother has a WRX which i checked what his fuel priming sounds like and it is noticable whereas mine does nothing all i can hear is the solenoids at the front of the car.

Checked to see if power is gettting to Fuel pump (drivers side behind rear seat????) and power is there when ignition is set to on

Does this sound like a fuel pump to all you knowledgeable people out there?

yup

check wiring under the rear seats

Well if power is getting to the pump and it's not going still then yup I'd say the pump is toasted.

Also check the main eaarth wire for the pup (its in the same plug as the power feed) both are the heavier gauge wires

If thats ok then YES - pump fail

just checked for the earth feed and its working.

Did notice that you said the two fat wires. One of the (has yellow on it) gets power when cranking. Then one of the smaller wires has power when ignition is set to "on" is this the way it should be?

If so then looks like ill be purchasing a pump tomorrow and doing it after work.

YEs, fuel pump power is primed then only continues to run when ecu gets crank rpm signal (saftey feature, so fuel pump stops when eng stops rotating , ie accidents / roll overs even tho the ign may still be on)

The other feed (is the gauge "earth") which runs all the time when ign on

got a s/h pump for a turb'd forrie, $40 plus postage.... just throwing it out there...

Thanks for all the help it was the pump.

Got one from sub euro 160 :'( but thats the price for needing car up and running now.

Thanks for the offers I would have taken the cheaper ones but it would have meant car would be out of action for longer.

The 160 was a full kits so basically

- unbolted old one from tank

- removed

- placed new one

- bolted up

- car starts (a part from flat battery)

plus they threw in a free ash tray i needed
