The b series 86-93 do not have a obd plug in for code reading.The ecm on the carburated and fuel injected trucks is designed to run the emissions and fuel controls soley.If your b2600 is fuel injected and running poorly it may likely be the ECM has some damage internally where the capacitors leak down and damage solder points on the electrical board and make the truck run very bad.
Look under vehicle follow fuel line from tank
Mazda truck b3000 where is the fuel pump reset switch located
In the fuel Tank
Fuel Injected? In the fuel tank
where i look only year 1994 mazda b4000 truck -fuel sending that find hard time
I need a diagram of the fuel tank on a 1994 Mazda B-2300 Truck
Check fuses, relays switches etc. Probably best to get a wiring diagram and follow the circuit.
On my 1989 Mazda B2600 the fuel filter is located on the firewall near the top of the engine compartment on the left hand side looking in. ***************************************************************** From RonSh: I have two 1989 Mazda B2200 trucks, probably from two different manf. facilities. On one truck, the fuel filter is as above but closer to the carburetor and takes 10 minutes to change out. On the other truck, to my suprise and angst, it is located behjind the fuel tank. Both are identical lookng. Be sure you know which line is coming from the tank and which is going to the front toward the carburetor. I had to physically feel and follow the lines because both go to an area hard to see without the vehicle being on a lift and I had poor lighting.
