Wait a minute. I've found that people's use of the word "crank" is all over the map. "It won't crank" means it turns over but doesn't fire, or it could mean it doesn't turn over at all. Two different animals. IF Chris's car will turn over but not fire, it's probably the DME relay. The DME Relay is actually two relays in one. One powers the DME (engine computer itself) and the other (controlled by the DME) runs the fuel pump. People and mechanics who are not familiar with 944's will automatically think it's an expensive fuel pump failure if engine is not getting fuel.

Of all the times I've had this issue on my 87 944, it has been the DME relay (Twice). The 88 944S I got back in the spring did have a fuel pump issue. I determined that by using my 3-way jumper (like the one in the Clarks Garage link above) wire to force power to the DME and Fuel pump. Bought a used pump for $90 and she fired right up. Discovered it had bad oil-cooler seals and a seized water pump about 30 seconds into it thought. Fortunately I had the timing belt covers off inspecting the belts and saw the belt start to smoke. Shewwwww...

Anyway, try the jumper and see if it will run. Don't leave it plugged in though, terminal 30 is hot all the time and you will run down the battery if you're not driving the car.
