I replaced the Distributor about 2500 mile ago, the vehicle ran great until the other day when it totally lost power and showed a code of Multiple misfire. I have checked the plug wires and cap and rotor and now the vehicle wont start. Any suggestions?

If its cranking over and refuses to start do below might lead you somewhere

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 camshaft and crankshaft sensors- Note: If it doesn't apply disregard it
