Hi Guys,
Just recently did a plug/wire/cap and roter change and it did not help my problem.
When the car is dead cold, it's start with no problem - I'm talking barely a half second of cranking and it fires up..

After driving around - even for 5 minutes and shutting in off, the car is hard to start. It will start but it takes a while. A while being like 2 to 5 seconds of cranking but it always starts. The starter is cranking perfectly and the ignition coil was replaced with a stock unit 8,000km's ago.

How often do you guys replace the ignition coil?
Smoke shoots out the back when this happens. When I changed the plugs, I noticed that there was some oil on them.
Is this my problem? Are my valve seals gone allowing engine oil to seep into the combustion chamber when warm screwing with the mixture?
Any help is appreciated..

 

Steve,

Presuming that you have a "normal" 1989 GTA, you have a TPI engine. I would suggest testing fuel pressure, and monitoring fuel pressure after the engine is shut off. Pressure should maintain for at least 15 minutes. If pressure drops off significantly in that time, you may have a leaking injector(s) and/or leaking fuel pressure regulator. Either of these can flood the engine while warm, making restart difficult as you describe. If you allow the engine to cool, the excess fuel has a chance to evaporate, making starting more normal. The smoke on hot restart is also a symptom of the excess fuel.

 

That may be it Lord vader.
This motor has approx 190,000km's on it so it's getting up there.
As long as it's harmless, i don't think i'll touch it till it's time for a new motor.
I got a feeling its one or more of the fuel injectors leaking in. Don't have a pressure guage though. Does anyone know of a company that makes a unit for a tpi that screw in on the schrader valve? (ones that stay on their permanently)
