Ive just bought my first rs turbo so im new to this and with in ten minutes of having it it started to misfire i havnt even driven it yet! or messed with it. it went from running well to a bag of s**t ive check ive got spark and fuel and its had a new dizzy on i took the dizzy cap off and noticed the spring loaded thing in the centre of the cap was missing so i fitted a new cap on and still got the same misfire but now it won't start at all also its got a toad alarm on and the pump won't come on unless i put a feed off the battery so the alarm must be cuttinf it out ive checked the relays and there all fine can anyone help me please??

 

Have you put the plug leads on the right way round when you swapped the cap, thats where i would start fella then get back on here after checking and will talk you threw it

 

yeah mate checked that loads of times the firing order?? . i was going get a new coil this week just to see if its that worth replacing anyway spose.
because it ran really well then one morning came to start it up ran but misfired

 

Sorry i read it again, right you have spark, you have air so it must be a fuel issue, right are you on a MFI or EFI engine

 

mfi with dizzy

 

Do you hear the fuel pump prime up when you turn the key

 

mfi mate yeah the pump primes and when its turning over it just pops and bangs really loud like its just burning the fuel then just stinks of petrol afterwards

 

ok not a band thing then your on the boarder of a start, dont unplug the cold start like a lot do as that just masks other faults. On the metering unit there is a small hole behind the air intake flap, turn it a 1/8-14 of a turn anti clockwise, then try start it, if you have a jump pack use this to to help, keep doing it till it fires, if it doesnt fire after you have turned it/done this about 5 time get someone to press the flap down about 1mm-3mm while trying to start it and get back to me

 

will do tmra after work mate thanks for your help

 

Do i need a allen key to adjust it?? never seen the adjuster??

 

Yea little hexagon bit will do. It sits on the metering unit when you look down on it. It's small and may be covered in dirt n grime

 

still no go mate tried and tried what you said

 

fireing order defo right?? 1 3 4 2
have u tried removeing plugs & giving them a good wireing brush/clean?
do u have fuel pressure at the metering unit? remove airbox/filer & see if there is any resistance on the flap when u push it down?

once the above are done ide look at fuel maybe:
bridge out relay to eliminate that
again unplug cold start valve

was the car running ok before u removed cap etc?

 

Toad alarms (depending on which model) have 2 immobilizers. One is for a fuel pump the other is to do with the coil pack.

 

What did you do to it from it running (shit) to not at all just messed with alarm etc or battery went dead etc etc

 

 

yeah getting good resistance from the unit i nevet touched a thing till it started missfire a cleaned plugs ive had 3 mechanics come up and still they can't get it run the fuel pump fine now took the imob off

 

Not trying to be funny here but do you have fuel or are you running on an empty tank?

 

yeah put 20quid init

 

Change the pump for a known good one? Is there power to the pump? Sounds electrical to me

 

the pump works u can hear it and the engine just stinks of petrol everytime you try start it ive turned the fuel down and still no joy

 

Could be a sensor issue..... Unplug the wiring to the metering head this will make your car run with no electronic enrichment..... DO NOT DRIVE THE CAR WOTH THINGS LIKE THIS AS IT WILL BE LEAN AND COULD MELT YOUR ENGINE.... But hopefully it should improve the situation on idle and will at least point us in a direction to repair it.

If this makes things better its most likely your coolant sensor or throttle position sensor or the wiring to it...

 

check earths. i had an issue recently were the car would just die, then not spark, all of a sudden it would start and all was well. turned out to be a earth (battery end) were the solder had fatigued at the ring terminal.
