engine not starting

Do below

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 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,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

i hooked the fuel pump up direct from the battery to an inline fuse to a switch and another fuse to the fuel pump i have alot of fuel going to the fuel rail just doesnt wanna stay cranked i had lost all power to everything that was wired to the fuel pump, relay, inertia switch thats why i hooked it up direct for now i think my regulator might have went out even though i dont see any signs of fuel in the vacumm lines
