vehicle originaly come into me for customers complaint of only being able to start on easy start and whilst driving cutting out.we have put a new intank fuel pump and new fuel filter and the green marked fuel hose as it had rubbed through.then i spoke to a very helpful person who suggested new injector copper washers and seals which i replaced.once i had gone through the self bleed cycle the engine started and ran ok.i switch the ignition off and imediatly tried to restart and it will not.i have fuel upto the fuel pressure regulator and with the cam cover off the injectors solonoids seem to be firing.

can anyone help

when you switch ign. on a pump primes without starting it do you hear it gurgling like its getting rid of air , even though you have done the copper washer the symptom is like compession blow by into the fuel gallery.

yes when ignition switched on pump makes gurgling noise.i had it running today for half an hour without it cutting out i switched the engine off and tried to start it straight away and it would not start.left it for 10 minutes held accelerator to floor and it restarted straight away there has never been any smoke from exhaust.when i took the original copper washers off of injectors there was no black particles on washers indicating compression leak past.
when oil was checked at start of diagnosis there was no oil in engine.topped oil and the oil has not gone past where i originally topped upto.

Hi

Gurgling noise would still suggest air ingress / combustion leak issue to me.

One of the filter ports ( outer rear from memory)has a bleed valve in it ( to vent off air trapped in filter housing) it will only cope with small amounts of air, but may be worth changing to eliminate.

The in tank pump is two stage on these & pipe work quite complicated are you familiar with the layout ?

Cheers Aidan

When you have run car then try to re start and it wont fire .......
leave ignition on fully deprss accelerator 3 times (it may be 5 times) pump in tank should purge again .

Do this a few times if needed and listen if gurgeling stops, then try to start,the gurgeling stopping is when the air is purged out of the system ..

If the gurgeling doesnt stop without you cranking the engine the air ingress could be getting in elsewhere and not compression being blown into fuel gallery.

Have seen faults on the fuel filter housing also like someone else said.

have you checked the wiring loom to the injectors as this can cause this problem check the plug at the front of the rocker box drivers side up under disconnect and look at connections if oily also check the loom to the ecu as it is a known fault with this engine that oil will back along the wiring to the ecu causing misfiring and poor starting clean the plugs, i use brake cleaner,and replace the loom inside the engine .you may have to have the ecu cleaned \checked.
bleeding the system ,switch the ignition on fully depress the throttle pedal five times, the eml will light up and the system will purge leave until the light goes out.hope this helps.
