Verify you ave good grounds available at pins 4 and 5 where you verified power to pin 16.

 

thanks hanky for the quick reply i only wish i could check 4 & 5 ground as quick as you answered. i took the truck to the mechanic they can't figure it out but i will pass that on to them this next week sometime.i will post if it works or not to everyone on this forum

 

Would you recall just what the anti-theft light did when you attempted to crank it over?

My first thought as I read your description was , are all the grounds connected and clean?
I hope you didn't spend $$ for a PCM when you really don't need one.

Also does the vehicle have a std trans or automatic?
All these things come into the pix and somehow I feel it is something simple that is being overlooked.

 

it is auto trans i don't recall seeing a anti-theft light on it at all i didn't think it has that capability for that year it dose have some kind of reset swicht under the passenger kick pannel i did try to reset but nothing happened i don't know if it has a neutral start swicht if it does let me know what you know oa thinking i have seen on some post that the anti-theft needed rseting but those were not the same year as mine and i am sad to say i have bought a new one thank you so much Hanky you are doing alot for me i hope it turns out that it's something simple becase i really like this truck
