Question about 1990 GMC Sierra
All ready change cap/rotor,coil and now the igniton module. first changed cap and rotor ran fine next day ran good then just died wouldn't start changed igniton coil started right up tried it 3-4 times started every time went out later and it didn't start so changed ignition module. Have not changed pick up coil on ditributor as of yet. what else could be the problem
Did you use the dylectric grease that should have came with the ignition module?
the module can be ruined by excessive heat, the grease is to insulate the module from too much heat.
also check for lose connections.
