Re: engine no crank dash lights go crazy when key is on
It sounds like your alternator quit charging and then your battery died. do you have a battery charger? if so, charge the battery and try to start it. If it starts but the charging light is on, you likely need an alternator. Most auto parts stores can test it for you.

Anti-theft system can keep vehicle from starting , Alarm is for vehicle content theft , open door without key alarm sounds (horns) ! PATS - passive anti theft system PATS enables and disables the engine from starting ,it will not cause the engine to die ! You have some other kind of problem ! If the vehicle engine doesn't turn over an red light on top of dash flashes fast ,then you have anti-theft system problem !
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.
If the anti theft light is blinking and you say that everything else fine.. My first thought is that the key is not programmed to the vehicle. The key has a internal chip that must be programmed to vehicle in order to start. Now my other question is, Is the key your using for the vehicle the original key or have you just recently had a key made? Regardless, in order for the yur Tribute to start, the key. Or keys have to be program to vehicle by your neighbor dealership. Thats the reason for your anti theft light is blinking
The problem may not be with anti-theft but with a bad fuel pump,cam/crank sensor etc. Also, you may try unlocking the drivers door with the key. On most cars that is the standard method for disabling the security system.
If the security system is at fault, the security light should be flashing or staying on.
Do the warning lights come on the dash when you turn the key on ? Can you jumper the starter relay and make it crank ?
What makes you think this is a anti-theft system problem ? Is the security light lit on the insturment cluster ? When you turn the key to start does the starter spin the engine ? Crank no start ! Or when you turn the key to the start position the starter does nothing . No crank no start . A aftermarket remote start won't by pass anti-theft system . Your best bet would be to take to a qualified repair shop and have it checked for DTC'S - diagnostic trouble codes . Before you let someone start hacking up wiring circuits .
Do you know what DTC'S are , these would point to an area of trouble an to a fix .
this is one way to reset it :
first make sure the battery is fully charged , then do the following:
key in the ignition but do not crank the motor, just leave it at the
ignition mode for ten minutes ,then turn it off POSITION for 5 seconds then REPEAT again 2 more times. at the 3 rd time youre gonna notice the ANTI THEFT light on dash to blink. when doing the last step , remove key , inserted again and turn on motor , good luck , AJ
