fueling

[Craigwilson]

what can cause an 8v digifant to over fuel, and before you say blue temp sender or ecu both have been replaced. it over fuels and won't start as it's flooded and when I force it to start it reeks of petrol and runs horrible

sticky plunger in metering unit?

sticky plunger in metering unit?

digifant not the K-jet. 

First common question: Does the fuel pump prime for 3 seconds with ignition on or run continuously?

[Craigwilson]

it's primes normally, I don't see anything abnormal with the car but it just won't fire unless I unplug the injectors to clear the fuel from it, and the plugs are soaking wet with petrol. I replaced the plugs and it started perfectly for a while (still running crap tho) and now it's back to not starting. whole ignition systems been replaced

Only thing I can think off is that the fuel pump relay is sticking.

I would check the fuel pressure regulator and the return pipe coming off it for blockage. would also check fuel pressure.

1) get plastic coke bottles and stick the injectors into start car
2) check each injector of spray pattern and speed at which they all should fill up.
3) check injector loom they get brittle due to being near the manifold.
4) either faulty injectors are stuck open or loom is earthing out.
5) Fuel relay check it

[gazareth]

if you can get the car to run at all take a long flat screwdriver and put the tip of it on each injector and your ear against the handle. you should be able to hear the injectors ticking quite clearly. if not check the wiring back to the ecu. if the wiring is fine then it looks like an ecu fault.

apologies I should probably let you know what I've done already, I've replaced my blue sender my ecu my injector loom( got a good one off ebay as mine had been repaired) the loom came with injectors and rail and regulator and I checked them before putting them in by plugging in an old dizzy and turning it with my hand when the ignition is on, my hall sender and cap are new my leads are new I've swapped the relay with my other 8v and done a continuity test of all my plugs and switches going to the ecu.

still nothing, it's been over a week now
