finished BD but 4.3 won't fire?!?!?!!! please help!

like the subject said... i've removed everything from under the hood except the motor, cruise, and brake booster/master cylinder... my motor turns over but it's not gettin any fire... does anyone have any ideas on what it could be.

what year is it?

we had a problem with the passlock setup on 1 of our trucks.... since we swapped a non tilt to a tilt.... just sumnthing stupid and it worked... check grounds

do you have all the grounds grounded?

Check and make sure that all your grounds got hooked back up as well as all the wiring. Pull a plug and make sure that your getting spark and chck to see if you are getting fuel. You can start to narrow it down if all the wiring is correctly installed. Good luck!

the passlock system can always be a pain in the ass on the 98 and newer GMs.....just check all you grounds really good and possibly unhook the battery for a few hours...then go back and try it again...usually once you get past the passlock the first time you wont have anymore problems out of it again....also make sure your coil pack is in ok shape and all of your plugs wires are pushed all the way in....good luck

Yeah , Check the grounds , even the ones at the back of frame .

is the dash in the truck? my truck wount start with out the dash wires connected.

SOUNDS LIKE A GROUND PROB LOOKS LIKE NO ONE HAS SUGGESTED THAT YET THOUGH

check the ground on the back left of the frame... it's the fuel pump ground i believe... i always used to forget to hook that bitch up after takin a bed off and would cuss the fuck out of it
