I have just purchased a 1984 Spider that has no fire. Have checked and cleaned all ground straps and all fuses. Is there any way to test the flywheel sensors or do I just have to replace them. Was wondering if I could just remove them and connect the 2 wires together and bypass them just to check?? Any other ideas or suggestions would be appreciated. Thanks for your help

No, you cannot bypass the flywheel sensors.
You can test them with a multimeter though.
Click the 'L-jet diagnostic page' link in my sig block for more info than you'll prolly know what to do with at one time.

But first, do you have more than 10.5 volts at the battery during cranking?
(don't care how fast it sounds like its turning over, what is the actual tested voltage)

Too low a voltage and the ECU won't wake up.
No ECU, no joy.

Thank you for the reply! I put a new "EverStart Maxx" battery, cold cranking amps 750. Will read through all the info from your links. Hoping to find it helpful.
