no PCM, its an old 1983 Ford mustang 2.3 pinto, with a carb & conventional ignition system My apologies. :oops: You did say that at the start. The GM module sent me off. ie. How is it possible for the coil current to still be 6A after the PCM has removed ground path. I assume this from what is bein...
The module is a GM hei unit with built in current limiter Is this a DFI with EST and bypass control? What was the original fault? Have you looked at the IC from the PCM. And for interest. Here's a similar capture from a Mazda, new coil and module also. As far as I got was it appeared to be caused b...
Oh crap, sorry I didn't read your post before posting my response. I agree with you completely. :lol: :lol: :lol: Voltage spikes indicate current flow Would this only apply where an inductive circuit is operating correctly? In other words the lack of a spike could indicate poor current flow or a sh...
Have you considered making your own resistive load using Nichrome wire? http://en.wikipedia.org/wiki/Nichrome
Same as your heater element but customised to your needs.
Just had an IAC on a wrangler (TJ) (short on to fuel rail inside conduit, rail had pushed through split). 4 wire. Each pair was always switching so two high and two low. As a thought looking at yours I would thinking Brown/Green channels OK. Blue/Red open circuit somewhere after the IAC. But as Robs...
Works out @ cyl #1 to me going by +1 rule....... I'm not sure what you're asking with the cranking compression capture ? Did you have the throttle wide open as you would with a gauge ? Rats! You beat me to it. To busy making pretty pictures. FF http://i232.photobucket.com/albums/ee88/Nobbyclrk/Miss...
