Rebuilt 318 install problem

10-4, but has it ran normal since the rebuild?
No, not been able to get it to run properly since build. Strongly suspicious of several things. It just occurred to me that he desperately needs to go ahead, pull the plugs, and run a proper compression check before proceeding any farther. I have been helping garage today that’s been working on my folks 06 Tacoma that had the frame changed in ‘16 by the dealer and came backbone without four wheel drive. Two new actuators and a new four wheel drive module and and goes into four high or four low but will not come back out of either. Can take a power probe to actuators once unplug them and put back in two wheel. Data site had 12 page book with three pages of schematics on how four wheel drive system operates. Almost brain fried. Anyone out there a Tieyotur certified mechanic?
