We recently bought a truck and a while after we bought it was shake for a second and die Like we were running out of gas, Today we were driving and out of no where our truck started jerking and then died, We pulled over on the side of the road and tryed to get it to start back up and it just wouldnt, My husband checked the Fuel filter and it was Fine, We know that it was on Empty cause we had just put 30.00 In the tank befor we left to our Desitnation.

Lets do below and get back with some results

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
