i have replaced the 2-4 band in my 03 yukon today. re-installed everything and now the truck will not start. i have all lights and chimes, the indicator lights work as i move the shifter through the range, we've tapped the starter while turning the key - nothing. When the key is put to start position all i get is silence.

any thoughts - this is on a 2003 yukon 5.3 4wd

oh and i also have "service 4wd" and "check brake booster" on in my display

thanks everybody

 

Do you have 12 volts goin to your starter when they key is in start position?

 

re check ur wiring.. did u disconnect the battery when u dropped the tranny? if u didnt check ur fuses may b when u were taking off the starter u made a short and blew a fuse.. other then that idk man.. check ur p to N safety connector..

 

Check all your wires and your P/N switch.

 

alright guys, which is the p/n switch? anybody have a pic?

 

oh and country boy, thats a nice pic there! sharp color on the truck and whoever the lady is, very nice too!

 

You didnt pinch the crank position sensor wire on back of engine did ya??

 

never mind on that question. its the block on the side of the case.
i had to tap the top connector into this for it to sit. after tryign to start the truck with no luck, i unplugged both connectors to make sure none of the pins were bent. none were, tried to put the connectors back in and they wouldnt go, so i pulled the weather connector out and tried, i got them back in without tapping. think i messed this thing up? anyway i can check this, make sure the adjustment is right? when i put the truck in park, it does unlock the doors and stops the truck from rolling more than a few inches, so i believe its in park.

 

timz, i dont believe so. i didnt see any wires hanging off the back of the engine anywhere. plus wouldnt it still crank just not start

 

Check the ground on the back of the block by the top trans bolt , also check the curcit fuses under the hood the should be green 25 with A clear lens ! I didnt disconect the power and blew them
