Do below to determine if its a fuel or spark problem
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem,Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

As noted above we tryed all that. No noid light to the injectors. 38 pounds of fuel pressure. No spark. Crank Position sensor ohm'ed out the same as a new one. There is no power to the ignition coil with the key on. Engin spins over fine but it does not run. All fuses are good. Recently it had an intermittant problem with bogging and bucking under acceleration conditions. It made it home we changed the sparkplug wires because they were cracked. When it first started this problem it said two codes which were P0351 (coil) and P0300 (random misfire). The battery voltage checks out to 12.8 volts.

Computer time. Used one from the junkyard about $30. In back of the radio (console specifically). Clean the crank position sensor? Okay.................... New ones are cheap. Do this first.
