Having trouble with my fuel shut off solenoid. Cat 216b. was blowing fuses so replaced solenoid. All was good.....for awhile. (3/4 months) Now it starts....Now It doesn't start. never know. Both (old and new) solenoids work at times. Doesn't matter hot or cold,start no start. Never know. any ideas? Thanks Jack [email protected] PS Love my Cat just need to fix it
