[V8] RPM/Ignition sensor issues!

[jpb3]

Thanks tony & Kneale for your input.  I did think that if they were hooked
up backwards the car wouldn't start or run to begin with so I have ruled
that out.  I think I am just going to buy another good sensor so when I go
back in that dark crapmped hole it will be for the last time.  It must be my
large hands but I swear this job was a real PITA, I can barely get my hand
through the hole between the AC compressor and the subframe and then turning
a bolt once I am on it is one millimeter at a time.

Thanks,

John
