Asked by viper1701dAnswer
Is it cranking over and refuses to start or won't crank at all/nothing.
If its cranking and will not start-d below
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
If its not cranking over at all/nothing l-could be fuse no. 10 20amp and fuse no.19 10amp, starter relay, transmission range switch and ignition switch.
