87 S10 Will Not Start

I been doing the cab mounts on my 87 s10 4x4 and well i had to jack up the cab a bit to get them on so when i had it jacked up i tried to start it.....nothing wouldnt even turn over, rocked the cab.....came to life now the cab mounts are on and it will not start i think i might of hauled a wire off somewhere is there any place i should look and check for or any suggestions on how to find it. Oh everything else in the truck seems to work all lights horn etc..

Chect the groung wire from the battery. You may have pulled it when you lifted the truck body. Check both ends. Positive and negitive.

Could it be that? everything in the truck will work just the thing wont wind over

check connections on the firewall to make sure they are all connected. there is a ground strap from block to firewall make sure it is still bolted down and not broke. check fuses to make sure you didnt short anything out.
check ignition switch and basically all connections that would of been stretched and pulled apart during lifting cab.
