Over last 2 months my 1983 944 Spec car is getting harder and harder to start when cold. Had to crank it a couple of times, then 3 or 4, now 8-10 before it finally fires enough to stay running. Once started it runs fine. Anybody know where to start checking? Seems like a fuel delivery problem, but I am not yet very familiar with the 944 injection system.
Thanks.
