    Hey everyone, I'm having some problems with my truck not firing. It used to run fine but would have intermittent hiccups (kind of brief bucking like it lost fuel for a second). After a year of driving and slowly looking for the problem it kept getting worse. It would run fine when cold, but once warm it would buck and jerk with any amount of acceleration. Finally it just died and won't fire at all.

    Before it died I had changed the plugs, wires, cap, rotor, fuel filter, fuel pump, ignition coil, and MAF sensor over time.

    Now when I take out the spark plugs and turn it over, they all spray a seemingly large amount of fuel out of the cylinder hole. If I look down into the cylinder there's a significant amount of standing fuel too. I'm thinking it now will not fire at all because it is just drowning out the spark.

    Here's a video of the fuel coming out when I turn it over. I assume this is an abnormal amount right?

    I've used a test light on the injector plugs and they seem to be pulsing normally when turning over. The resistance at the injector plug is around 14 ohms each.

    I do not have a fuel pressure gauge, so that is on my to-do list.

    Any thoughts or similar experiences?

    Thanks!

    One of the signs of a bad ignition switch is it will start when cold....

    but dies out when you try to give it gas after its hot.....

    Cost me $20 for aftermarket one to find out....
