Question about Cars & Trucks
No crank , the horn blows when you turn the key to crank the engine. The drivers door latch has gone bad and has been replaced. The problem started when the old door latch malfunctioned and you couldn't open the door from the inside or outside.
The truck has a feature, where you turn the key in door lock , the alarm should stop going off. there is a small switch on back of the lock cylinder. it may have popped off and is in lock position, but you cant turn it back to on position, because it popped off from the back of the lock. remove the door panel and look inside of the door where the lock is. make sure, that the switch is attached firmly to the back of the lock cylinder. start there.

jimmy: it sounds like the drivers door unlock tamper switch or the other switch may have failed. One side can affect the other under certain circumstances. Your trunk lock also has a switch which arms and disarms the antitheft system. Try locking all the doors, make sure the hood and trunk lid are closed and then open the trunk. Leave it open open the drivers door and try to start the car.
If it's a no start. Disconnect the ground battery cable then put the ignition key in the run position in you ignition switch. Reconnect the battery and try to start the car. It should start. This usually will override the anti theft system. One issue with this will be, whether the antitheft system will remain disarmed.
Although I have never tried this before, I know that the system will not arm unless all the doors, trunk and the hood are closed.
I could suggest this to try if the car starts as I had told you pertaining to disconnecting the battery cable, I would take the switch and unbolt it from the passenger's side of the engine compartment just forward of the shock tower. Just let it sit somewhere so it doesn't get caught up in anything moving. If there is a light under the hood of your car, remove the bulb.
Let me know how you make out.

Start with fuel system. Listen for fuel pump humm at fuel tank No humm check wiring to pump for power. Then check for spark at plugs and wires. Remove wire from coil and hold near engine and see arch when you crank. No arch. Replace ignition Modular inside distributor cap or cap or rotor
