Re: 91 Regency Elite died coming down the mountain
Well, as it stands right now, you have no spark, on any cylinder?
If you have a single coil, with 6 terminals, that is known as a Magnavox coil......they have a history of breaking down, but it is usually a "pair" that is the problem, not all 6......
So, if you have no spark at all, it comes down to the crank sensor, the ICM, or the coil pack, or the harness between the Crank sensor and ICM(you had a problem with the harness at the cam sensor), or the harness from the ICM to the ECM..........if this is the case, I would remove the ignition wires(make sure they are labelled, so they go back correctly)..... now remove the coil(torx screws).....when you flip it over, you will find one side of coils with a common wire(usually power), and the other side of coils each has an individual wire(control wire from the ICM to create spark)......disconnect the wires from the bottom of the coil pack(make a note of how they will go back on)....what you want to do, is attach your test light to the common wire.....attach the other end of the test light to one of the three individual wires....now crank the vehicle....the light should flash.....try another wire.....it should flash...now try the third wire.....it should flash......If all three flash, bad Magnavox coil......if only one or two flash.......bad ICM.......if none flash, then it's either a bad ICM or crank sensor.....
One more possibility, is a bad harness connection at the ICM........have seen techs go in there and not using the proper test leads, force the female connectors open a little .....over time, vibration takes it's course and you end up with a bad connection....only way to test these connections, is with the appropriate male connector, and you insert it into each female harness connector, and then pull it out....should "feel" the same "drag" from each female connector....if loose, the connector should be replaced....
