If your running the K-Jet system I would be suspecting a possible air leak between the intake valves and the air flow sensor. Although this type of FI system is easy to work on and less of a hassle (IMHO) a leak causes havoc at cold starts because the air is cheating the air flow sensor thus the sensor plate does not move up far enough resulting in a lean mixture when you really need a rick mixture to start. Another thing to check (if you do have the K-Jet) is the control pressure regulator. When this plugs up it keeps the control pressure above the fuel distributors plunger to high thus the plunger can not muve down as much as it needs to and it can not give you the rich mixture needed. Anyways if you have the K-Jet and need more help feel free to e-mail me. Good Luck!

Sincerely,
