how do you end up getting the truck running when its acting up ?

Customer: replied 7 months ago.
Last two times put jumper cable and it started today it just started one time I turned it off and would not start back didn't try jumper cables again had to leave to go back to work this morning b4 work it started rite up sit for about 5 hrs today then would not start back
Expert:  Gary replied 7 months ago.

right now its hard to say why adding a jumper cable made it start up

can you see if it will start with jumper cables now ?

usually when the theft/security light is blinking when it will not start the issue is the key OR the passlock sensor that reads the key to a BCM or an ECM issue

usually if you have the BCM and or ECM codes read and there is a code set for the passlock system then replacing the passlock sensor should correct this issue

if no codes set in either module then usually the issue will come down to a weak battery or bad battery cables or the ECM or the BCM being bad
