Does anyone know if EM relay controls all engine functions including power to plugs..I assume not as when I remove this relay it still sparks when cranked but fuel will not pump down fuel line ..this produces same fault I had that so spanner wouldn't flash just stayed on and wouldn't do pedal test.

I am going to change both relays ..I looked in EM relay and there's a resistor or diode in base which I think is switch to operate coil in relay ..it looks uncooked but would imagine it all gets hot in there near engine for 15 years!!

Success ..the car seemed to fix itself before I checked the fuel pump power.

I thought I would look at pink relays for injector and pump.
They get warm quickly ..I removed the one nearest battery and it gives me exact same fault and EML will not flash on peddle test.

So it would seem it's a dodgy relay.

Where's the best place to get correct spares .

I hope that's it fixed now ..also with relay removed TC light stays on!!

I am also looking for camcorder gasket fir 2.2 facelift petrol.

CAN I SAY THANK YOU TO ALL WHO HAVE HELPED ME!!
Jimbob is a true gent on every respect

Ok just done a bit more.
No fuel present in either fuel line to injectors .
Plugs bone dry but correct colour.
Can't here fuel pump running when I turn ignition on.
So if I am correct its pump or relays for pump .

Where would I find relay for pump.
Sorry just seen previous post car is level and quarter of a tank of petrol .

Thanks for all the info..QuickStart is 50 percent do methyl either and whilst it promotes ignition on a petrol engine the compression ratio isn't high enough for it to ignite..the only reason I know this is the research a friend of mine did and it's ignition promoting qualities on compression engines !!

When I have a mo and some daylight I will take potentiometer off encase it's stuck or there's something obvious but other than that I'll need to substitute it..

It would be nice to get to the bottom of this!!

Hi yes I don't like QuickStart but it proved one think no fuel .

As I can read codes i am
Thinking potentiometer ..is there any way to test ..I will check fuel first dispite what guage says.

Good news got it to fire up for a few seconds by using QuickStart straight in to throttle body so it seems to be fuel ..I will put some more fuel in but what else could be preventing fuel getting in to engine with code issues not reading could it be throttle potentiometer

Just to say thanks to Jimbob disputed the horrific weather kept trying to get the old girl going ..thanks

There's quarter tank of petrol even though jimbob a computer said less..again power??

I am wondering if there's a cell out on battery ..this would give under voltage dispite jump leads?

I  am charging battery ..have had all electrics on a lot and maybe it's just not enough to run all engine electrics and crank ..will advise

Hi I know spanner light is needed and I have used it this many times but it will not flash just stays on..the last time this happened eventually engine started after being left for a while then EML light worked normally again for fault reading

Hi

I am doing pedal test as I have done in past brake pedal and accelerator pressed and turning ignition on but not starting ..just stays on no flashing .

When I crank engine tacho needle moves so new crank sensor seems ok..I had same problem before I cleaned gear selector switch and put new Vauxhall gem crank sensor on ..ran fine for a few days then same fault with TC light on !!
