Some times my car does not start. I will put the key in the ignition dash board lights up and cranks. And some times I will put the key in and nothing happen it is like the car is dead not power, no lights no horn completely dead. I wait a few minutes and the it works light nothing ever happen. Is there a switch that turns on/off the power when you step on the clutch to turn the car on?
Make sure that the connections at the battery is clean and free of acid built up. Take the terminals of and clean them propperly
It could also be the ignition switch at the wiring end not making proper contact anymore, try and wiggle the ignition wiring if possible and see if there is any change in the status when the ignition is switch on

battery good 11 v min
battery conecctions cables, all clean
if automatic trans, in park or neutral selector
if standar trans, press the clutch pedal full down, check switch in pedal
the dash lights all on in switch on, check for antiefth extra
and doors closed, seat belts
or crank start but engine no start need a full diagnosis for qualificated personal.
I think you were on the right track with the key lock and ignition switch. It sounds like the lock is not turning the switch far enough.
There are gears between the lock cylinder and switch that may not be aligned up right.
The anti-theft system would prevent the engine from cranking, but the security light should be flashing if the system thinks the truck is being stolen.
Are you certain the security has not immobilized the car? If it isn't a security issue, there is probably a problem in the start circuit.
If you check for power on the small starter solenoid wire, with the key held in crank, and no power is on that wire-the start circuit from the ignition switch to the starter solenoid has a problem. If the wire does have power with key in cranking position, probably a bad connection from battery to starter, since you have a new starter.
To be certain the engine is not locked up, put a socket and wrench on the crankshaft pulley center bolt and turn the engine over by hand a revolution or so.
well if you have a dvom/voltmeter check the power at the starter terminals. the main terminal should have power all the time the key wire should have power only when the key is turned to crank engine. if you have power at both then i would start looking at grounds
ANY TIME SECURITY LIGHT COME ON YOU HAVE FAULT IN THE IGNITION KEY OR KEYS THEY COULD BE WORN OUT WHERE TO A POINT WHERE THE BCM AND PCM DONT RECOGNIZE THE CAR KEYS CAUSING NO START CONDITIONS.ALSO WORN KEY SWITCH AND BCM WILL CAUSE NO START CONDITIONS.TRY THESE TWO THINGS TRY ANOTHER CAR KEY IF STILL DONT CRANK.PUT KEY IN IGNITION TURN KEY TO ON POSITION WITH ENGINE OFF LEAVE KEY ON POSITION IN IGNITION FOR 10 MINUTES WATCH DASH SECURITY LIGHT WHEN IT TURNS OFF IN 10 MINUTES.TURN OFF IGNITION FOR 5 SECONDS THEN TRY STARTING CAR IF CRANKS OR DONT STILL THE PROBLEM IS IN THE THEFT SECURITY SYSTEM NEED TO GET DEALERSHIP TO FIX THEY HAVE DIAGNOSTIC EQUIPMENT TO FIX AND REPROGRAM THEFT SECURITY. SYSTEM.
when the car ignition is turn on all accessory lights should lite up telling the computer everything is in good contact. If none of the dash lights is not lighting up you don't have a good ignition contact and computer is not getting any power. your stater will crank and turn the engine over only but the fuel pump and ignition module and other accessary is not turn on, the car will not start. What turn everything on is your computer, computer; control all items like fuel pump, sparks etc. You have to get all dash light working again in order for computer to turn on. Check all the fuses and relay under the hood, next your ignition switch in your steering wheel may be faulty allowing only starter to work and not others. this unit wear out and common problems to all cars, parts is 35 buck to replace and you going to have to take the steering columns apart to get to it. Not easy but it will take time. Get all the dash light working and you will be back in the game. good luck and hope that help some
check and recheck all conections on battery and starter and grounds on battery and the ground on engine bblock and body ground or grounds,if not sure make another one ,check connections at battery ,it does sound like a bad ground to body and eng just make ur owne and see what happens
Electrical problems are difficult to diagnose in person without testing ...however, it seems that you may be loosing the body ground, causing power loss to the clock and likely the computer as well. As the starter is able to turn the engine, likely there is no problem with engine grounding. While cranking, the accessory side of the ignition switch should remain "hot" otherwise you would loose the clock every time you started it up. If it's not a ground problem, I'd look at the ignition switch itself to make sure it's not dropping power to ignition system while starter is engaged. on some vehicles this can also happen at the starter relay if an ignition bypass is used to provide hotter starting spark.
