This is probably a really dumb question, but should everything have around 12 volts if there is power going through it, or will the voltage vary depending on what component I'm testing?
(Well after a late night of prowling around the house the cat is up again and ready for more hunting.)
A very good question actually and from what I have seen before the signal wires will not be 12 volts but more like around 5 to 7 volts I believe.
You are correct about pin 52 and after looking over things again I see I wasn't looking at that pins function correctly in the past.
Along with making sure the power connections are as they should be I think it would be wise to make sure the wiring between the ECU and the disty crank sensor is intact as well. This brings up a question, have you checked the ECU for error codes yet?
