The truck will no longer start. Turns over fine but wont fire. So I replaced the camshaft sensor also changed the cap and rotor still wont start. It has about 58lbs of fuel pressure and it has spark. Im going to check the crankshaft sensor tomorrow but other than that im not real sure where to go with it. Can you please help

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, 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

I have pulled the number one wire off and have spark but it seems live it only sparks about every other revolution. Some one said maybe a bad coil
