Bigt's Big MK 2 project temperature problems.

does it restarts once it dies? is the engining turning and firing?

Keep researching... Bentley Manual: VW GTi, Golf, Jetta 1985-1992

Hey yea once it dies, I can turn it back over. Once I turn it back over it splutters and idles for a little bit then dies again.

Thanks for the manual link, but I already have been using it at nauseum....

Will try the relays and the main pump inside the tank to see whether its fueling properly.

Thanks again

When it dies, what does the tacho do/show?
Just falls to zero or does it bounce around wildly?

[bigt]

Starts losing revs initially then dies.. And if you try and accelerate it does not have any "go".......

[robiom]

Just in case, are the plug leads and dissy cap & rotor good?
Check the connections are not corroded....could be breaking down when hot...

Are all the vacume lines new too?

Good luck.
Rob

[bigt]

Dizzy cap and rotor are new, connections are spot on cleaned out and all.....

Vacuum lines are all old, but connectors and hosing are in tip top shape. Air bubble tested on the last run so can rule that out too.

Latest drama is that my outer fuel pump is leaking from the hose ontop of the housing and my pump is noisy(not tip top).
Will replace that and see were we get to. Also my fuse box is getting re-done with all new relays and fuses, because it appears I have an iffy connection in the "ecu relay" plug.

But we shall see tomorrow what the day brings otherwise ill sell the car ($7k with engine, $10K without) haha jokes.....

Could be the Air flow Sensor.... The airflow sensor contains an intake air temperature sensor.... could explain that as soon as the car warms up, you might have hot air flowing through

[bigt]

Airflow sensor and box have been checked, all clear.

[OEM G60]

Did you actually replace the temp sensors, or just test them?

[bigt]

Replced the blue one. THe black one is just the switch to the gauge and is working. The airflow meter was checked and given the all clear

[OEM G60]

Bugger! I used to go through a lot of those blue temp senders...

[OEM G60]

Try replacing the coil, doesn't have to be a new one, just try another! I've had a problem with an original one, that i replaced with a new one, and had the same issue. Put a used one in and it was fine. Mine would cut out after about half an hour of driving, once it got up to certain temp, didn't like it when i sat at traffic lights! This was on an 8V G60. Took ages to suss what the problem was!

[bigt]

Yea I'll need to source one from the uk I believe(cheap like $5).

Can you use a MK3 coil or a SEAT coil of a similar year?

Mine cuts out as soon as it reaches operating temperature(5mins of idle) and cuts out when I plug in the "blue temp sensor".
Does unplugging the blue temp sensor bypass the coil? Thus running always on cold and destroying my fuel pump(metal shavings in housing!!!) ?

Need a definate before i go chasing one up. There is a local wreckers that has a 91 SEAT and a MK3 GL, will i need to steal the coils?

[OEM G60]

I'd ask someone like Volkspower in Burwood for one, or even someone on here.
