[V8] V8Q Still no start

[Tony and Lillie]

Eric,
There are a couple of things you need to check. First, did you make sure to 
plug the RPM and Reference sensors into the right connectors? Also, did you 
replace the RPM sensor, not the reference sensor? If you have no bouncing 
tach, and no spark, it has nothing to do with the fuel delivery. There is 
something wrong in the delivery of the signal. Next step is probably to 
check the connections at the ECU. Maybe do the resistance check there. If 
you need help with pin location or specs, let me know. I have the manual 
right next to me.
