1984 ranger. about a month after replacing fuel pump 2nd time and having carb overhauled, truck suddenly stopped during a right turn and would not restart. mechanic that did previous work got truck to his garage and next day truck started and we couldn't make it not start. set up at home several weeks and then will not start. disconnected fuel line at carb, turned over starter several times and did not get fuel.
Sometimes there is a plastic strainer in the gas tank and when they break down they will clog the fuel pick up. After the suction stops the pieces settle until the next time.
Ever replace the fuel filter or check for fuel getting through the filter?
Besides the inertia sensor which needs to be manually reset, some of these motors had an inline fuel pressure regulator. Another area can be a crankshaft sensor which adjusts fuel pressure to RPM.
Believe the inline pressure regulator works off vacuum so the "check engine light" would not diagnose. On the other hand, the crankshaft sensor should generate a trouble code. Curious as to what you find.

You mention no check engine light, and all the work you've done leave one solution; Your catalytic converter is clogged.
When you replace you catalytic converter your issues will cease. This is a very common problem, and a simple fix.
I hope this information helps and I wish you luck with your repair.

Loose connection is the problem. It takes petience to find where it is at. Do some wiggling on wires to see where it is.
SOURCE: 2001 Ford Ranger cranks but doesn't start periodically
If it has a distributor it is possible that the reluctor / stator has a broken wire. preventing the computer from firing the engine. This can be intermitant and would require the removal of the distributor. If the engine has a crank shaft sensor then this may be a possible place for a broken wire or bad connection. Location for these can be on the harmonic damper at the from=nt of the engine or located at or near the flywheel......

GO TO AUTO PARTS STORE BUY A FUEL PRESSURE GAUGE THAT CAN CHECK FUEL PRESSURE UP TO 100 PSI. LOCATE YOUR FUEL PRESSURE TEST PORT.LOOK FOR SCHRADER VALVE ON FUEL LINE NEXT TO EGR VALVE.PLACE A RAG NEAR THE SCHRADER VALVE AS YOU INSTALL FUEL PRESSURE GAUGE TO CATCH GAS SPILL AS YOU SCREW IN FUEL PRESSURE GAUGE HOSE FUEL PRESSURE 30 - 45 PSI WITH ENGINE RUNNING. THE ENGINE MUST BE OFF HOOK UP THE FUEL PRESSURE GAUGE.IF YOU HAVE TROUBLE THE FUEL PRESSURE GAUGE WILL HAVE INSTRUCTION HOW TO HOOK UP FUEL PRESURE GAUGE.BE CAREFUL CHECKING FUEL PRESSURE IS DANGEROUS JOB.DONT ALLOW NO MASSIVE FUEL SPRAYING WHEN HOOKING UP FUEL PRESSURE GAUGE YOU WILL GET CAR FIRE.
