98 truck - Starting problems

    I have had my 98 truck for alittle more than 2 years. Lately it's been giving me starting problems. If i drive the truck everyday I usually do not have any starting problems. If I let it sit for about a day it'll act up.

    When it acts up, the motor will turn over, but with breaks in between. If I hold the key down to start it'll crank then a short pause then crank then pause and so on. I usually wait a few minutes to try again. After waiting, it'll crank again, but this time it'll fire up then turn off quickly, as if the security is turning off the fuel pump. After about 15 minutes of trying she will finally fire up and run. Usually after that it'll turn on fine until the next episode.

    I have replaced the starter ( twice ), and my battery is fully charged, putting out 12+ on volts. I also had the security light come on a few times but turn off. Could this be the problem?

    I would really like to solve the problem myself versus taking it to a shop.

    Anybody out there encountered this problem before? Any ideas or suggestions?

    Sorry, I forgot the details of the truck.
    It's a 98 Chevy C1500, 5.7L Vortec motor.

    My first thought is that you might have a faulty ignition switch. You'll need to remove the cover from the steering column and probe the wire terminals while it's acting up to be sure.
    Good Luck and God Bless

    Here's a great video on removing the ignition switch. I didn't produce it, but I wish I had watched it before I took mine apart. Would have saved me a few hours.
