Car won't start when cold, it is flooded, I have cleaned the injectors checked compression and codes and all are good. As soon as the car is warm/running it is easy to start. However when cold i have to floor it to cut the injectors. I did a search on this and only found things with hot starts, not many problems like mine. Any help ideas maybe a dirty sensor in the intake manifold I don't think the injector is leaking i just think something is telling the ecu to dump in more fuel on cold starts. I have a 90 gtu w/130k the car is totally stock except for a gtus diff and bonez cat replacement. I bought is off an old man who was the first owner and took good care of the car.

As a good course of action, I would replace the battery cables. Old cables can rotate the engine slower than normal and the car will flood before it starts. Same issue with the starter. Also, check the FSM or Haynes and troubleshoot the Thermowax sensor on the back of the throttle body.

Sure sounds like leaking injectors or poor compression.

How did you clean the injectors??? Did you remove them and have them ultrasonicly and solvent cleaned?

What is the compression???

compression was around 100, and i cleaned the injectors with lucas injector clean. What is the proper coarse of action to cure a leaky injector? I have a feeling that is what it might be.

Injector cleaner can only clean so much. And i been noticing that alot of older cars has cracked injector tips. I don't know if this would cause flooding or not. But you can replace the seconary injectors with some used primary injectors from the junkyard.

Nothing poured into the tank will ever clean a really dirty injector.

The injectors need to be removed and professionally cleaned.
