Truck has sat for 5 months and now will not start. It has a new battery. First diagnosis was distributor cap & rotor, which was replaced. I was told by the shop that it then started, ran for a few seconds, sputtered and quit. They say the fuel pump is the problem but it's inside the gas tank. Another $575.
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, 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

My 97 pickup would not start. Replaced SFI = start but would not run properly. Replaced catalytic converter = all better.
