I had bought a.fiat punto that would not rev. Found the head gasket had gone between 2 cylinders. Replaced the gasket and it fixed the problem. So going to try that route first.

A simple gasket check test will save you the bother of replacing it.

If you carry out a leak down test on each cylinder it will reveal if the gasket is ok or not, or a basic compression test will show a shared compression between two cylinders.

I tried that but i got a reading of 0 compression on all cylinders which can not be true. With oil and water mixed in the radiator and on the oil filler cap it's a good sign i have an issue.

Latest thought. Although the replacement ecu got the car running it still cuts out after a short lenght of time.
I know the fuel pump still holds pressure until after it stalls so it might be due to it being the incorrect ecu. Have ordered a spark tester to see if the spark plugs are still trying to spark when it cuts out.

Will need to sort out your compression & HG issue before spark is an issue. You must be chasing several problems or have an extremely bad run of luck.

The car was only £200 and not been on the road for over 17 years. If it had been on the road recently or was a couple of grand i would be disappointed, as it is I expected problems so just need to deal with one at a time. My old mgf known for head gasket issues would still tick over and rev when the hg went. I've owned over 80 cars in the last 30 odd years but not come across this issue before.

As above, have a basic compression test done to eliminate a shared compression issue, then carry out a leakdown test to reveal a HG issue, then and only then can you move on to other things further down the diagnostic tree.

Also, i have a pretty mint low mileage 4a-ge sat here if you find you'd rather just replace it all for something that 100% works without further hassle.
