Mike, Since your car is cranking slowly but can run, I would think you have a power delivery issue either due to too small cables or weak ground. Does the car always crank slowly? This can be an issue since the starter is consuming all the electrical power the resulting voltage drop is insufficient to supply the DME to fire users like the fuel injectors, fuel pump and plug coils.
My suggestion would be to temporarily run direct cables from ground post to the engine block and one to the body near the DME. If still no go then a positive jumper directly to the starter then test.
