Hard start on 89' chevy 6.2l
Sorry Red, I meant to say the throttle position sensor, not valve. I have found that mine performs best all around if the timing is set where it is at 0- +1. I moved the position of the throttle to be more open at start, and it made it a little easier on the valves, but still hard to start so I may move it back. I have to assume that the TPS is working properly because of the way it runs once started.

The throttle position sensor is not used for fueling on your engine, since it has a mechanical injection pump. It would be used to determine shift points for the transmission. However the different openings of the throttle affect starting and idle. I found on my truck when it was cold it liked just a little more throttle than idle for cold starts. My truck started pretty good when I had the timing advanced, but when I put the turbo on I moved it down to 1-2* and it had a harder time starting after that. Do you have the cold start solenoid on your throttle bracket? You could try adjusting that.
