First off, be sure your master cylinder is full of brake fluid. Now, starting at the driver wheel, behind or on top the caliper is a bleeder screw. Loosen this screw. The brake fluid may start running out on its own(gravity bleeding)if not then you will need someone to pump the brakes. Using a second person, close the bleeder screw and have them pump the brakes then hold the pedal down. While they have the pedal down, open the bleeder screw and then close it after brake fluid stops coming out. Repeat pumping and holding the brake pedal down then open the bleeder screw until you do not see any air bubbles coming out, should only take 2 or 3 times per wheel. Do the same for the rest of the wheels, starting at the drivers wheel then the passenger front wheel, then the driver rear wheel and ending up on the passenger rear wheel. Make sure your master cylinder does not run out of brake fluid or you will have to start over.

try getting a chilton's manual from the parts store might have to order it for this truck but the give very good schematics in them for the wiring and vacuum systems.
you are going to have to search junkyards for that, good luck. hard to find anything from the 90s, much less the 80s. Do a google search might be an Isuzu old part specialist out there.
you can only really see it from under the vehicle i had the same prob but i found it. its behind the bell housing and in front of the oil pan if your laying under the car with your feet out in front of the car, look to follow the same sort of wires that come off the battery to the starter. It is above part of the exhaust and is close to the driver side wheel well.
did you check for fuel and compression? Check for compression either with a compression tester or pull the plugs and one by one stick your finger on the top of the hole and have someone crank it. whether there is compression or not you will easily be able to figure out your answer. Also make sure you are getting Fuel if im not mistaken the 85 had a carb. again while someone is trying to crank it see if you can see gas squirting into it if not i'd go the route of either a clogged fuel filter or bad pump... the 3 things a vehicle needs to run is compression spark and air/fuel mixture
You don't need to bleed all of the brakes, just the one you installed. Hopefully you have someone handy to help you out. In case you aren't already aware: open bleeder, press brake all the way to floor, close bleeder, release brake and repeat. Don't run out of fluid. For future reference there is tool out that fills the lines from the bleeder to the master cylindar so you force air out of the lines from the caliper while also filling the lines. Good to have when you decide to replace everything. It's also a single person job so no more pumping the brakes, filling the resivor and keeping your fingers crossed that you got all the air out. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/matthew_d24b835e574ef6ca
HI, Ive just put a 2.6 4ze1 injected motor in a 95 rodeo in oz, the supply fuel pipe connects to the one sticking out at the front of the efi manifold next to the battery & air con hose! Make sure you have fuel in the tank, also you might have to prime the air out of the line by putting a rag around the hose & turning it over with your finger over it. Lightly releasing each time to let air escape until fuel comes out & being extremely careful for fire hazzard & to yourself!!! Then fit to manifold, the other pipe heading down under the manifold must be a vacum or tank breather hose? I hope this helps you GARYB in australia!!!
