Car Got spark and got fuel but wont start :(

[Bigdunc]

Ok i got a mk2 8v digi, 2 weeks ago the car starte then died on me with in seconds, ever since that the car has not started again for me

so i have changed plugs and changed the dizzy cap no difference, i checked my coil and cleaned up the terminals on it, so i take plug out of the head and you can see a spark from the plug so i know i got a spark, i took out all the plugs and cranked engine over and you could see mist pumping out of the engine.

so it seams i have a spark and i have fuel but for some reason the engine wont fire

ive changed my ecu and no difference and replaced some earth straps

whats next to try??

Set it up using the guide in the maintenance section.

Timing has probably fallen out. Either that or plugs are on wrong terminals on dizzy.

i cant set the timeing withoug the engine running as it needs to be set at 2-2.5k at 6degrees, i can set the dizzy to tdc with the dead engine and twiddle it abit but i really dont think its timing, the dizzy haddnt mooved and if it did move it hadnt moved enough to stop the car running. the plugs are in correct terminals on the cap,

i really dont see this being a timing issue though

My valver suddenly lost it's timing set point. Parked up one night, wouldn't start the next. Took me and a mate just sitting there turning it over and jiggling the dizzy around to get it to fire up. Then it ran like a bag of nails before I took it to a rolling road for a full set up.

I'll try that later but when my mate finishes work, cant remember if already tryed that or not though, I was thinking maybe the air flow unit Poss has got a fault??

[Bigdunc]

I've twisted dizzy while cranking and no joy I fitted a new coil to give me a stronger spark aswell, still not working

Are the crank, cam and dizzy aligned with each other? If so and you have fuel and spark, have you checked all electrical connections, and vacuum hoses? My next guess would be to swap blue temp sender with a known good one.

All is ligned up, almost had it fire earlyer by playing with the needle in the maf unit so I think it's the contact in the unit if I moved the needle up manually it would light the fuel but not enough to start car but seams like its probably the maf

[herr schimdt]

do you have compression as head gasket mat have gone you nead fuel spark compresion and air to run an engine do you have all of these if so it should run

[Bigdunc]

Head gasket was done about 1k ago, I'm sure it's maf after my recent test I took the plastic cap off the maf and manually moved the needle while cranking and it fired for a second, that's the most life I've had out the car for 3 weeks now so going to change the maf and see of it works
