All,
Compliments of chasing an intermittent no-start for months (only lasted a minute or 2 then started right up) I have new (not used): FP Relay, CPS, power stage, coil, and some spotless grounds. It had been running for several weeks with no problem after the last component replacement (power stage) so I had my finger crossed that it was solved. Now the intermittent came to stay and it won't start permanent. Lucky for me it happened right in front of the house.
I have +12 both sides coil with key on but no spark in the coil wire during crank as verified by timing light and my nifty spark gauge I built around plug wire 1 which lights a neon light on the dash. I ran out of light today but according to the very good 740/940 no start guide I need to verify the inputs to the power stage next. I can't believe the 3 week old power stage is bad so let's say I verify the inputs and they are not good. What does that tell me? The no start guide kind of ends there. All I can think of is the ECU not providing signal to power stage or the ignition switch is not providing voltage. Am I missing something else?
Thanks,
Robb
