Hi guys,

After some extensive preliminary mantenance, I've had my 1989 IROC-Z on the road for a few months now and we've started to hit our first few 'cold' days in las vegas (between 30-45 degrees F).

I've noticed two unrelated problems:

1) Car hesitates to start while cold. The starter must be cranked for 3 second intervals 2-4 times prior to catching. When it does catch, it bogs, stutters then picks up.

2) The steering power assist seems to cut out when cold. When backing out of my parking spot, it tends to 'sieze' while moving though out the lock. Once it is warm, it functions as normal. When cold only a slight trilling sound can be heard, like a very quiet pigeon. Other than that, it makes no unusual sounds; no characteristic belt/pump squel.

My guess for the issues sources are as follows:

1) I installed a new fuel pump/tank. One of my Co-workers mentioned I could have 'twisted a fuel line'. I assume they ment I could have somehow put to much pressure on the line restricing fuel flow. I doubt it as the tank has hard lines from the pump. Could is just be the MAF system being less efficient than the mass density system on my old 1990. This is my fist winter with this car and I have nothing to compare it to. My 1990 would start on the first crank every time.

2) I did adjust the sector shaft. There is a chance that I moved it beyond centerpoint. However, it works fine once warm; perfect in fact. So I find it strange that it only seizes while cold. Could it be the Power steering pully? Or perhaps the belt?
