My 89 si's been sitting since thanksgiving break because of an incident on the highway where it sounded as a gunshot lefty exhaust and all of my lights came on in my gauge cluster. Haven't driven it since. Back when it happened, I checked everything internally; head gaskets good, cam and belt is in time, no bent valves etc.

The car fires but does not want to turn over. As I would hold the key forward, it would try ... Giving a little backfire every 3/4 rotations, but wouldn't turn over. I'm boggled by this, my dizzy, spark plugs/wires are all pretty new.

Anyone have any ideas? Possible sensor? Stumped ... SOS

So no cam slipped?

jdavis94teg

Surprisingly, no. Not from what I could see. Belt still had tension, was maybe a snip of a tooth off but that's it .

jdavis94teg

Anyone?

all cylinders hold compression???

jdavis94teg

Didn't show signs of blown cylinders. Oil wasn't milky so didn't think anything of head gasket etc.

did you throw a rod?

jdavis94teg

does it turn over or not???

jdavis94teg

It does NOT. It seems like it wants too, but doesnt

I'd check that the rotor button screw did not back out. Put a good charge on the battery also.

Screw was actually broken inside the rotor button, Head of the screw was doin whatever throughout the dizzy cap. Going to get a new diz, hopefully this is the fix.
