    Ok so here it goes
    my truck won't start.
    i drove it to work the other day, and parked it, after work i came out to start it and it would start, then die right away.
    I finally got it started, and it drove home just fine.

    now sometimes it will start, and die, after it sits for a while it will start and run, but now, it won't even start.

    i think my radio was shorting out before, it was flashing on and off, and that was making the injectors click like a solenoid.
    i think the radio was shorting out, and now it isn't any more, but it still won't start.
    any ideas?

    check for spark...

    if your by yourself, just squirt a little fuel in the TB and see if it wants to light that off...

    pull a plug tonite and leave the the plug wire on it and hold it with some insulated plyers if you dont want to get shocked and have someone crank it over and see if you got spark or if you have a timing lite start puttin it on each plug wire and see if it lites up to see if you have spark, prolly something in the dizzy

    seems like ryoken has some easier methods than i do lmao, mine will still work though, the timing lite will tell u which wires are working and which arent if you have any bad ones, im guessin its prolly ur cap, rotor, or coil though, all cheap things to replace

    Next time it does the no start, try the fuel trick.. That'll let you know if it's a fuel or an electrical issue..

    I'm betting you have some intermittent ignition issue...

    Do you have a noid light?

    What year is your truck again? My ignition module was shot and acted a lot like that.

    Mine would die after running for a few minutes. Sometime it would start right up, others it wouldnt start at all. I dont think the check engine light ever came on either.

    They are easy to replace and cost around $40. Someone else may have a better idea though.

    Mine did that same thing, as soon as it cranked it died. If you hit the gas as soon as it started it would run though just not start and idle, it also smelt like it was flooded. I replaced the IAC and it has worked fine for a week so I,m thinking that was it. Another guy told me to check the gasket under the throttlebody.
