Where to start here...

So the car is a 92 camaro with the 3.1 everything is stock and most of it is original.
I recently replaced the fuel pump and filter, plugs cap rotor ignition module and coil. I was driving down the freeway and it just dies and wouldn't fire up for about an hour (was cranking great the hole time) so i got it started drove home and now it again wont start. I plan on Pulling the codes here soon, other than that where should i be looking

Since it is a '92 and has the VATS system I would start there.

Re: Where to start here...

most likely a fusible link. does it/ did it cut off over a bump? mine would stall and would restart fine a whole bunch of times. needlessly bypassed vats.

Re: Where to start here...

If the engine still has the original Multec injectors they are likely bad. The coils short out preventing the ECM from firing any of them. Gets worse with a hot engine.
