I have a 1991 TT that is hard to start after it sits for 4/5 hours. It starts just fine in the morning or if it sit for a few minutes. After it sits for 4/5 hours it will start but you have to turns it over and over a few times. Plug/air filter/ have been changed. Thanks Marvin

 

Any ecu codes?

 

Any more details? By hard to start to you mean that it will turn over, yet not fire? Or does it fire but not start. I would check that you have ingnition spark (have you checked the recalled transistor unit?) and your fuel pressure (could have a fuel pressure reg that is sticking.)

Once running any difficulties at any speed?

 

I need to check for codes .

It fires but won't start I believe. I will need to check the transistor unit and reg.

Thanks for the help.

 

It could be one of many things, try being a little more specific on the side effects, such as sounds, feelings you get, etc.
