Cranking but not firing 1991
hey everyone
new guy with first vette and it's a project car! I posted an intro thread as well.
So the column is kind of trashed and the ignition switch is sloppy so I think the wiring for the key pellet is damaged.
I get cranking/starter running but not firing. From what I've read that isn't a typical failure mode for a VATS problem.
If it is I want to bypass it just to get it running now so figure out what I have. I will rebuild the column after though.
Is chasing the key pellet reader wiring the right way to go?

Did the car ever run or did you buy it with the column all messed up? How do you know that the column is your problem or are you guessing?
If it were me, I'd start by rebuilding the column the right way then do the diagnostic on the engine. The column need to be assembled correctly as there are bunches of connection and grounds that effect your start/run procedure.
Do you have your Field Service Manual yet? (FSM)

I need to order a FSM and the column and the switch are super sloppy. The PO believed that was the problem so I probably need to diagnose it further before going all in.
The keys measured in range #7

Thanks! I bought the car non-running like this for $1,800. Probably over paid! lol

You need to go to the base of the column and check the wiring from the key pellet contacts. You should measure the resistance of the pellet when you do this. Look for two white wires in orange sleeving. Unplug the connector and measure the resistance between the white wires. If the resistance shows open, the wires are probably broken at the ignition key cylinder.

.very helpful! thanks!
