1992 Mazda Other

Engine Mechanical problem

I have replaced the ditributor, coil, ignition module, and fuel pump and the truck still will not start. What do you suggest I check now?

Dunno if your problem is spark or fuel that's causing it

Do below and comeback with some results we start here.

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, 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, cap and rotor /distributor pick-up coil, ignition control module, ECM, Ignitor cam and crank sensors- Note: If it doesn't apply disregard it
