Today I wired in a new 044 fuel pump plus new wiring loom. Can started and ran spot on. Next thing I was out just driving to my mates. At the time I was doing 50mph went to put my foot down it came on boost and bang big cloud of white smoke running on 3 cyilders and then cut out... Got the car tow home first thing cheaked compression all 4 cyilders are the same around 150 psi.. Used a bore scope and found number 3 was full of fuel!!.? Checked injectors and changed with my standed ones still the same turn over and not fire bore still has fuel in. Checked spark all ok.. Changed my stage 3 chip back to stage 1 still the same turns over and fills number 3 with fuel only thing I can thing of is the ECU gone up the shit!?. Any help would be great as I am lost and don't no wot to try next.

using the bore scope, does the piston look in good shape? are the valves in the correct place?

Rs sid

All the pistons look ok just number 3 is full of petrol. As for valves I haven't looked but it has compression?.

it cant be many things then can it

could be the ecu telling the injector to stay open, someone got a spare you can try?

Rs sid

That's wot I am think if I have done something to short the ECU out when i was tryibg ti work out how to wire up the group A coil I don't want buy one if its not that plus my mates all have 2wd ones so not much help.

Just have to cheak over all the sensors in the morning and go for there

It could be a dodgy wire to the No. 3 injector. They are fed with 12 V from ignition feed, the ground is switched by the ECU. If the ground wire to the injector is shorting to earth, the injector will fire continuously.

So today I have spent time checking all the wiring to the injectors etc. all seem ok. I have took the injectors out and turned the engine over to see how they are working and all spaying right. Cylinder 2/3 full of fuel.. I have sucked all the fuel out and wot I can't work out is why there still fuel some how getting in there when there no fuel lines/injectors on the enigne!?. I no the engine oil I the sump has fuel in so need to drain but trying to work out if the map señor or fuel pressure reg has failed to do this doesn't make sence as all I have fitted was a 044 fuel pump and five miles down the the road its now broken

jb 3 door

Fuel pressure reg failed sucking fuel up vacuum pipe and into inlet manifold,disconnect vacuum pipe and it will stop filling inlet

Think u could be right 👍 as just been outside checked the fuel pressure reg vac pipe and is full of petrol so I have to order a new one. Plus give it a oil change as well now just hope it hasn't f@@ked my bottom end up

jb 3 door

it will be ok ,had a 3 door towed to me years ago that had been everywhere and had everyone baffled but i got on to the fault after removing the injector rail with injectors and engine was still filling up with fuel,that turned out to be the fuelpump,when i checked fuel pressure the pump was putting out 8bar,check the pump,hope that helps,if pump faultly it will burst new reg

Recently happened to me but mine managed to still run albeit badly.Took an hour or so to figure it out. Fuel came out of the vac pipe like a tap . Ordered new plugs new oil and filter , the new reg and changed the coolant sensor at the same time .

happened to me, engine starting coughing, i popped the bonnet to see liquid coming out of the turbo, then it was on fire

Rs sid

Well this all happened after fitting a brand new 044 pump how do I check to see if its ok or will it just be that the 23 year old reg had just gave up as one thing I will say since I had it stage 3 before I change the pump at high revs it was trying to cut out like lack of fuel.?? That why I change the pump or was it the reg giving up on me

I have had the same problem and it turned out that the return pipe to the fuel tank was blocked, resulting in the regulator to split.....

when you put the new reg on, check what pressure you have

I was sent the wrong chip once and this sort of thing happened and I had fuel mist coming out of the air filter!!

Rs sid

Well I took the inlet off tonite and its full right up with fuel. So everything going be taken off and cleaned. Going order a new fuel pressure reg and work out how to check the fuel pressure in case the new pump running to much pressure
