hello guys, mazda noob here. got a 2003 B3000 from a family member a few months ago. It had rough idle when I got it and a check engine light. changed plugs, wires and a new coil and since then its been running decent with no check engine. We were out running around yesterday and come back from a walk and the truck wouldn't start. Not a battery issue, battery is turning it strong. it was more like a no spark thing. a passer-by stopped to lend a hand and he was able to tell there was spark from the coil when I tried to start it. after about 20 minutes of chatting and talking though things, we decided that I would have it towed to a friends shop this morning. The nice couple brought us home and after about 30 minutes we went back to where we left the truck and it started 1st start. upon startup, I noticed a distinct knock...but after about 10 seconds, the knock stopped. the truck has plenty of oil because I keep a good check on that type of stuff. I do remember during the several times I tried the ignition during the no start period, that there was no movement of the oil pressure needle. I drove the truck to work this morning and home with no issues. started first try and no more knocking. suggestions??? thanks

update. after a few months of no starting issues, it left me stranded at work, of all places. anyways, I hopped a ride home and 5 hours later it started fine. after all said and done, it got to where it wouldn't start at all. picked up an Airtek fuel pump from rockauto and it started right up. removing the bed was a very easy job and made it so much easier. I am too old to be rolling around on the ground dropping the tank.
