Use the search function.

Way to many threads regarding this topic.

Mk1 doesn't fit mk2. Get the correct setup for your car from a fuel injected mk2.

MK2 FI has a surge tank coupled with an intank lift pump.

Plenty info available on the search function.

If you fit a mk1 pump then everytime the tank gets half the car will start dying or surging and the pump will not last very long. You are making it suck fuel up from the tank which it is not designed to do. it will sort of work but give you trouble in the long run.

You say, you got "everything" and converted to MP9. Well that does not tell us what is everything and whether it is from a 1.4 , 1.6 or even a 1.8 car. Please indicate from which car, sensors, manifold, distributor and etc. You will likely need to adapt the throttle body via set procedure and could or could not have missed a part or two for the full setup.

Yeah it makes a difference where the plugs go.

You may have 2 swapped around.

Also get the FI dizzy. Timing is important on MP9, it has to be set using a specific procedure in order to get the dynamic timing control to work.

On that note post a list of all you have fitted to the car and a few pics of the engine as it stands now. Maybe we see something that can help solve your issue.

Another common reason for fueling issues is the temp sensor, though I think in your case it's more related to getting it setup right first.

Hi Evin!
We just installed a 2.08v head and injection system on a 1.6 converted to 1.8L carburetor and it stalls . Did you advance the timing to make this problem go away? Thanks!

Hmm, my brother says it must be related to the crankshaft rotation sensor. He mounted the sprocket and sensor outside near the timing belt.
Yes, he runs the fuel injection now, although runs is too much said. He tested it a bit but runs improper and it also gets like a rev limiter at about 5500 rpm. Your problem seemed like ours but I am not sure it's the same.
Thanks for the info!

Yes, can be but not sure, I'm running it with short loom and open box, so I don't have the crank sensor, but check all sensors it is a real struggle, and don't use the carb dizzy that was my biggest problem. Good luck guys

He is using the distributor from the 2.0l, so that shouldn't be a problem. Many thanks!

There is your problem exactly.

The 2.0l distributor doesn't fit properly into a short block.

The long block has a larger diameter opening for the distributor vs the short block. This is super important as the distributor shaft drives the oil pump.

Mk3 distributor for the 1.6/8l will fit the motor right and be plug and play for the MP9 EFI.

Also check fuel pressure. If you buy a cheap mechanical oil pressure gauge kit and a 6mm "T" piece, join it into the feed to the fuel rail. Anything less that 3 Bar or 45psi is bad.
