8v fuel advice needed please
« on: 03 March 2012, 14:37 »
ok so its a 1990 golf gti 8v digi. was running well then stopped running after what sounded like misfiring under load, I'm getting spark, air and fuel to the injector rail, but should the plugs be getting wet if I'm pumping the accelerator peddle? because mine is not so I'm thinking that the injectors are not working? anyway to check at all? it cranks over but does not even try to fire up both the fuel pumps are priming and like i said i have fuel to the injector rail. I've also looked at the timing and its spot on.

Any help as I really need the car for work

What happens when you unplug the connector to the air flow meter

I had an issue on mine where it had spark and fuel, would fire for half a second or so and then die. That was a dodgy cable to the meter

  • If I can't fix it at home, it ain't getting fixed.

If there was a serious wiring fault for the MAF there is a chance it would start with it unplugged.

Also, pumping a pedal does nothing fuel related when not running.  This only has an effect on carbed cars.
