Through your own admission, you need
to go to a repair shop, which one would
assume, you always go to

try locking your car with the key and unlocking it with the key, leave it for 30 second or so between the locking and unlocking , the car thinks some one has tampered with it

Has the check engine light come on at all ?

2 things come to mind, first check and clean all battery and starter connections. second, maybe you have something draining the battery. next time it rolls slow, put on a battery charger and see what happens. also, even though it is a new battery, it still could have a weak cell.

Turn the ign switch to run position and disconnect battery and reconnect

I had same issue. I thought it was a fuel delivery problem but I then noticed that while I had it on a battery charger it started up immediately. I noticed that the speed of the starter/flywheel was significantly quicker leading to the conclusion that the battery just needs to have more cranking amps. When I told this to a mechanic friend of mine he told me that it had something to do with the computer and that I just needed a better battery, more cranking amps. I just bought a battery today might even get a bigger one

i had the same problem, and it turned out the coil pack was moulding inside wich stopped the spark all together, i ended up changing my coil pack and putting on new wires because the ends connected to the coil were very corroded and that cures the not running part just fine


enjoy

when you turn the key you should hear an electric clik sound from under the steering column. If not your ignotion switch is bad, not the cylinder where the key goes but the switch. If you do hear a click, then check your starter soleniod. This happened to me 3 weeks ago and it was my starter.

test the alternator thi keeps the truck running
