Re: 96 7.3L no WTS light, no start, just turns over
If one of the sensors that use the 5V reference signal short, it will have the same symptoms. Not saying that's your problem however, just something else to check. The sensors that use it are the EBP
, and MAP
. You can try disconnecting each of those, one at a time, and see if the WTS light comes on when the key is in the WTS position. The EBP
is one of the more common ones that short internally. If that doesn't work, there could still be a short in the 5V circuit in the harness (Brown wire with White stripe for all those sensors, going to PCM
connector pin 90). I've also attached the tests for that circuit. Cheers!
