1992 ZR-1 VATS(?) problem - ZR-1 Net Registry Forums

dorri732 · 06-24-2012

I have a 92 ZR-1 with 122,000 miles on it. I've owned it for about 6 months. During this time it has periodically refused to start (no crank) and when this happens, the security light is on. I'd say somewhere around 1 in 30 starts this would happen. Irritating, but not a huge deal, as waiting 5 minutes would see it start just fine.

Recently, however it has gotten much worse. Now it's probably 1 in 4 starts that this happens, and it sometimes takes 30 minutes of trying to start every 5 minutes before it will start.

The pellet reader in the ignition key has been previously bypassed by soldering a resistor into the leads. This was done by a previous owner. I looked at it and it seems to be well done, no loose connections, resistance is 7.5 ohms.

I replaced the battery, as I had read that this sometimes helps, and I didn't know how old the battery was.

Also, when this happens, push starting the car doesn't work. I assume that rules out the possibility that it's the clutch switch or the starter itself.

I'm kinda at a loss here and am looking for any suggestions.

Thanks in advance.
