long crank when cold

Hey, I've noticed that my truck when cold or has been sitting for about 7 hours or so it takes a while to start. Would this be a sign of my ignition coil wearing out?

It was with my 3 month old MSD coil. Put the stock coil on, fired right up. Good trick is to warm the coil up with a hairdryer and see if that clears it up before throwing parts @ it. I'm glad I keep my stock/spare OEM parts around in case of failure.

If that isn't it, it could be something from the TFI, dizzy. Let us know what you find.

Ford Fuel Injection » Engine Coolant Temperature Sensor (ECT) Here is a link on how to test the ECT sensor, I would be inclined to check it out.
