Could be security. Does the light stay on and/or flashing? Turn the key to run, let sit for ten minutes, turn off for 30 seconds, try to start.This is reset. If you need relearn, do the 10 minutes and 30 seconds 3 times then try to start. Throw a charger on it because if the lights come on it will drain the battery. Any interruption, ad you have to start over. It could be a starter, wiring, or a bad neutral safety switch.
Sounds like dirty corroded battery post connections...remove from battery clean and/or replace the post push in terminals...these can be purchased through your local parts store for under $5. They are push out...push new in also clean inside the battery connections...be sure new posts are tight...all systems will need to reset after the dis-connect...Hope this helps.
Try replacing the cold starting valve. Also, it would save the battery and starter by cranking a couple of turns then stop. Wait a few seconds giving the fuel time to run into the engine and crank again. It should fire right up. Count to ten.
could have a battery ground , check cables for corrosion. could also be the starter or the solenoid. you could also have a dead short in the battery itself, it will be ok if it sits but will give you fits for repeated starts
When you turn on the key the fuel pump relay causes the pump to run for one second to bring the fuel manifold presure up. If the vehicle has 'sat' for a long time, this one second is not long enough and so the engine is struggling to get enough fuel to fire. Try turning the key on and off every couple of seconds for about a minute, then turn the key to the start position. The engine should now start. Do not touch any controls such as the throttle, the computer will take care of all this.
ok here you go
make sure the battery is fully charged befor starting
turn ignition to run
attempt to start once then release the key in the run position

turn key to run position
let vehicle sit for 10 minutes
turn key off
wait 5 seconds
turn key to run position

My 98 Jimmy runs on synthetic oil and starts well after sitting in cold weather. If the weather is the problem, try checking that. If it is warm... sorry no ideas.
