The shops around here didn't say that there was a relay, but knowing F/I there's got to be one somewhere. Another friend said that the ECU controls the pump.
Any answers.. Let me know.

sounds like an ecm problem.i am working on a 93 2600i,i have been all over this truck.it started with a cold no start and got worse.i got a ecm out of my bosses wrecked truck plugged it in truck runs like a sewing machine again.

Go to this web site Mazda B2600i ECM-ECU Lifetime Warranty $190 and read about our trucks. They cured mine. I highly recommend them.

I bought a 93 B2600 extended cab running poorly last year (2014). It has 150 # compression, all cylinders. I changed it to a carb (I made the intake) and equivalent of '89 carbed engine distributor (altered 2200 distributor), runs great, will spin a tire on take off (automatic).
Now all I have to do is rewire the a/c as vehicles in the seventies were, no more bot worries.
