Can't start warm engine, only when forceing to 20 degrees cooling water

Hello guys.

I have some problems with my engine. It is fully overhault and convertet from auto to manual. I'am using the auto ECU. Pin number 44 is grounded.

If engine is cold i get start on it at once. It warms up as normal. But when i stop the engine on round about 70degrees i can't start it anymore. If i force the coolant temperatur down to round about 20 degrees in Conzult it will start again but runs very lumpy. Have testet to raise the temperature degree by degree. The engine stalls right after raising to degrees.

TPS is on .44volt. Fireing is on 15degree. Idle control is already changed from another running engine. On conzult its showing the right coolant temperatur.

 

Hopefully someone can help me.

Thx a lot.

Sounds like you have a flooding issue likely caused by a bad connection at the water sensor, this will cause the cold start ( enrichment ) to occur and flood the plugs, is the electric fan running by any chance ?

Thx Jeff

I think the water sensor is working correctly because the temperature showing in Conzult is very stable. Or is it the little second sensor?

Don't have any electrical fan because dismantled air con.

The wiring harness is also new.
