my 1990 mazda b2600i 4x4

Then stick a hose in the fill hole on the side of the transmission and pump oil in.

You'll need to drain and fill the transmission and transfer case independently of each other. On the transmission, there are two drains and one filler port. You can see the filler port in the top left of the picture below.





Here are the steps for the transfer case...



You'll probably want to pick up a pump like this at your local auto-parts store if you don't have one already.

Hey man just saw your post i am 17 these mazdas are getting younger owners with new ideas XD and I also recently traded my car for a mazda great trucks these things are!!!

Well I need some advise my truck was running fine till a few weeks ago and it drove fine to school then after school it would just turn over and not fire.. well I got it to fire twice and it idled really really funny idk. I got a new fuel pump, distributer coil, and ignition module.. still nothing?? Any ideas?

Nevermind the new parts... First you need to verify that you have spark and fuel pressure.

My dad said I have neither. He thinks the computer is bad? Does anyone know if you can get the computer tested?

sounds like an ecu failure to me, pull it out, take the cover off and check inside for corrosion/leaking capacitors. if you know anyone with the same truck that you could test a good ecu in your truck just to make sure. now do you get fuel pressure when cranking the engine, or for the first 3 seconds when you turn the key to run?
