My 96 stalled on the highway. I thought I ran out of gas. I added more Gas and it did not start. I waited a few days still no start. Please help.

 

Start with basics.

Unplug a plug wire, connect to a spare plug, lay on manifold, crank - any spark? If no spark suspect crank shaft position sensor if you have a model that does not have a distributor at front of engine (thing with 8 plug wires coming out of it).

If you have a distributor and no spark - suspect ignition amplifier.

If you have sparks check for fuel pump running (should run for a second or two when key switched on). Fuel pressure test point on injector rail (right side of engine) - looks like a tire valve. 32-34 PSI would be expected. No or low pressure consider fuel pump (or electrical to same) and fuel filter. Also press reset button on top of inertia switch on firewall. It turns off fuel pump in a crash.
