1992 camaro 3.1 80000 miles died .upon inspection i found that the coil wire going to the distrubator was rusted and the dis. post came off with the coil wire. replaced with new cover ,rotor and coil wire,still no spark to plugs also tried a new coil. engine cranks over fine,fuel pump runs. rusty under dis. cover. all gauges seem to work,but when cranking over the temp gauge pegs all the way to highest temp

The pick up coil under the rotor buttton is probably out. Check the voltage on the red wire connected to the coil. If it has 12v then it is the pick up coil. I am pretty sure it is the red wire. It was on my truck, but it is the wire that isnt hooked up to the distributor.
You have to pull the distributor to replace the pick up coil. If comes off of the bottom. I changed everything on mine. Then ended up having to get another distibutor because it was rusted and seized up. wouldn't come apart. Got rebuilt one at autozone for 100 with trade in.
