any ideas? cold start problems

my 92 YJ has issues with starting while it's cold, and my tech can't seem to pinpoint the problem- car has been in the shop for a week, and i just bought the damn thing july 1.

what it's doing: when cold, the engine takes *forever* to turn over. we're talking 10-15 mins of constant cranking. when it's good and warm, no problem, it starts right up.

what the tech said: says it's definitely not the fuel pump or the pressure regulator, but it's an issue with a sensor array (?). he mentioned something about a cam shaft sensor, but i was unfortunately in a hurry and didn't catch exactly what he said. Forrest (the tech) is just about as frustrated as i am, since this issue is only an issue when the truck is cold- so the shop has about a 15 minute window twice a day to do whatever diagnostic testing they do.

any one have any ideas as to what this could possibly be?
