Car Cutting Out

[GTI-R Nath]

I was driving my car today and it cut out, now when Im trying to start it, it fire up runs for about 5 second then cuts back out again. I done a fault code and got 55, because i thought it might of been the throttle position sensor. I have also cleaned the MAF sensor and made sure no hoses have came loose.

Has anyone else got any suggestions of things i could try to get it running again thanks.

check the fuel filter and pump

i can hear the fuel pump prime when i turn on the ignition, and the fuel filters only about 2 months old, when it cuts out when i was driving it didn't jolt like it was struggling to get fuel. it just cut straight out and rolled to a stop lol

Take the Fuel Pump out and check the filter is not blocked.
Or could it be a faulty Immobilizer?

Check the battery terminals; sounds a bit like a complete loss of electrical power?

the fuel pump is only a year old and i changed the Walbro tea bag for a better pick up filter 3 months ago when i changed fuel filter. The car dose have a Toad power key on it but i have no idea how to disable it, if that is the problem.

ill check the voltage on the battery an and alternator see if there all right.


it starts and i can rev it once and then the rev needle just drops to 0 then it cuts out, thats why i thought it was the MAF or split in boost pipe but they seem fine,

sounds like the fuel pump is losing power to me, or its fubar which is not unknown for a walbro.

do all electrics work with ignition on?? dous it struggle to turn over?? could be your aultonator! as there mite be enough in the battery to start it but when you rev it its draining the battery!

all the electrics work fine, and the car fires straight up, the alternator and battery are both under a year old but Im still gonna check them.

check the simplest things first for example earth straps, loose wires in engine bay. more than likely be somthing or nothin!

I got a lift up to my car tonight to see if i could get it started, or get it towed to my house, since it was in a car park 3 miles away from my house. When i got there i tried to start it and it started 1st time and drove fine all the way back to my house lol

Will have to have a good look at it tomorrow and see if i can find what caused it

been trying to fix this now for a few days but still got the problem, the car has a dodgy idle when it starts cold, and usually cuts out, then starts fine on 2nd attempt..

then after that the car will drive fine for about 10 minutes, then it just cut out with out any warning, when it cuts the light on the dash light up and the steering and brake goes stiff making it hard to pull over

after it cuts out it will start but idle drops and car dies straight away , and i usually have to wait 20 minutes before the car will start and drive again.

the car is defiantly getting getting fuel, i have also checked the ignition system, done a fault check, checked the battery and alternator, and cleaned the MAF sensor

was wondering if the ideal control valve could cause this, I also noticed that my turbo timer had been acting strange, but not sure if a turbo timer could cause this problem..

Hmmm definatly sounds like somthing electrical. im not to clued up on R's as im quite new to them myself.

Have you checked wires from altonator arnt loose or have a crack in them or a bad connection?

Mine has only cut out on me once when a boost pipe came the intercooler which will stop it from running. but as yours runs for 10mins or so have you checked your intercooler itself for splits or holes as this may strech after hitting boost?

Is the fuel pump always noisy?

Could it be the imobiliser?

Fuel filter may be blocked?

dont realy know what else to tell you mate? hope you get to the problem soon!

If the alternator was at fault the battery would not be able to keep starting the car for very long at all. If once the engine cuts out, there is enough power in the battery to crank it over again then there would have been enough power to keep the car going in the first place. The starter saps loads of current from the battery when cranking, loads more than when the engine is just ticking over.
If you had a leak on the boost hoses somewhere, I doubt this would affect the car starting and ticking over as your not in boost and it would have to be a massive leak to stall the car (too much un-metered air going in).
As others have said, it does sound electrical though. In my experience; when it was fuel related, the car would slowly die. It must be the ignition or sensor side of things to make it just cut out like that.
Does it cut out whilst your foot is on the gas, or when you take it off and it goes to idle?... reason i ask is i think I'd rule out the idle control valve it happend whilst foot on accelerator?

Coolant temp sensor for the ecu maybe?

I had the engine running tonight, and i unplugged the MAF sensor, and nothing happened, but when i plugged it back in the RPM dropped to about 300, and the engine idle stayed very low like it was struggling for about 10 seconds before it returned to 1000 RPM, so now thinking this might be the problem.

Im not getting a code for a MAF fault, and the 2 wires on the sensor looked ok when i cleaned it, but i've heard the Plugs on them have dodgy connections sometimes, and also that they need re-earthed sometimes.
