1994 Buick Lesabre 6 cyl Front Wheel Drive Automatic 175k miles
Spark plugs (new) show weak, arching, yellowish spark. Not a sharp, blue snap as normal.
Tested wires, ICM, coils, crank sensor etc.
Unplugged PCM connector & checked with test light from BAT+ to the PCM connector Pins # B11, B12, B13, &B14. The test light lit bright on each.
Checked with voltmeter from Pins #WC7, WC8, &WC9 to ground and have 11.5V
From whence does this failure come?
have the same problem?
