The above concerns can be caused by the distributor Hall Effect sensor. When the above concerns occur only at cold temperatures and the engine starts and runs satisfactorily when warm, use the first diagnostic procedure. If the concern is no start, use the second procedure.

If a T.F.I. is removed from the distributor and the stator connector is soft or mushy, replace the stator.
