I have a problem w/ cold start on my 1987 16v. I put in a new motor, and the problem started. Above 50 no problems, but when its cold I have to crank for 10 minutes. Anyway, I have gone through the trouble tree, and I have 7000 ohms going in to the computer, but nothing coming out. Do I need a computer or is there some unknown secret? I will probably rig it up w/ a switch off the ignition crank signal if I need a computer. Suggestions?
