More than likely because of a short. its probably a shorted ignition switch
coil wires are crossed, you are sending juice to the negative lead when you hit your key
Check to see if you are getting fuel.
Determine the problem and see if you can fix it or not. If you cannot determine what's wrong then find someone that can. A trick to starting a vehicle is to pump the gas while you turn the key in the ignition. There are a million different reasons as to why a truck won't start.
Wires connected to the starter incorrectly or defective ignition switch.
turn steering wheel to left tight while turning key
you shorted something. is there a wire grounding out somewhere?
Dead short between ignition switch and starter solenoid trigger wire?
By turning the ignition key...
With a key, by turning on ignition
For Ignition. Your car will not start if this fuse blows, generally if there is a short.
may be a bad starter..... or if the engine is cranking with no start it could be the ignition wires
more than likely is the ignition module. What year?
after truck warms up will be hard to start,module may even start turning white colored make sure you are getting 12 volts to the module from the ignition also good luck
fuel pump relay
Well somethings i need to know? Is the truck engine turning over and just not starting? If the truck is turning over i would first off guess either gas or elelctrical problems. If the starter is not turning the engine over, then i would point at the starter relay (you should hear that click when you turn the key). Also if you find that the relay is fine and it is just not clicking then i would look at the ignition switch on the steerin column. . ) Also, it may be the ignition control module. If the engine turns, but no spark, this could be the ptoblem also. Good Luck!
Your ignition switch crapped on you
No, if it starts on its own without you turning the ignition switch then the ignition switch is defective.
