Hi,
Great forums here, hope to get some help as well.
I have a `95 Camaro with a 5.7L stick that will not start. It was backfiring after starting for a while, if you`d rev`d it slow it would seem to run
fine, but stab the throttle and it stumbled and backfired, but now it will not start at all with the starter. It has good spark on all plugs, weak to no injector pulse on all injectors while cranking, but will not fire, pop, or anything while cranking (even if you add fuel to through the intake). Here`s the really strange part, about 80% of the time when you release the key from crank to the 'on' position, the motor tries to run backwards!! It`ll crank the correct direction but will pop off and roll over real slow 2 or three times trying to run backwards after the key is let go from crank, if you release the clutch in gear while it`s doing it, it`ll move backwards in a forward gear. We`ve done a complete tune-up, cap rotor, wires, plugs, changed the optical eye in the distributor, changed the ignition module, changed the coded tumbler and key, removed the aftermarket security system (which didn`t appear to be tied into any ignition wires), replaced the opti, replace the jump cord between the opti and main harness, replaced the ignition switch, replaced the computer all with the same results. A diagnostic scan with the latest Snap-on SOLUS scan tool says nothing is wrong. Get behind the car with the 4-wheeler and shove it down the alley and pop the clutch it fires right up and runs fine. Trying the starter while it`s rolling down the alley and the same results as it sits still, pops off backwards when the key is let go from crank. When it did that I figured it was the load from the starter that was doing it, so I isolated the starter load from the rest of the car with another battery so the cars electrics didn`t know the starter was cranking, and the same thing, no start and tries to pop off backwards. It seems like a security thing but was told `95 doesn`t have the ability to change the timing and keep it from starting, but it sure seems to be. Any ideas and or responses would be greatly appreciated.
Thanks."
