ignition module prob.
 

ignition module moumted to coil keeps going bad. third one in three months, lasting a month at a time and throwing a P1351 code. can clear code and will start but only if i clear it. works a couple of times then have to replace module. think brain may have something to do with it?

Had this issue on a older truck. Ended up being one of the wires going to the coil was frayed and grounding
