The only test is to watch it on a live data scanner while the engine is cranked over, then compare it to the graphs in the factory service manual. Resistance testing doesn't work here.

The fill pipe is right back there. Check to see if a hose has been damaged. Check the spout area, is there a overflow pipe or a seam that could be leaking into the trunk?

How to test a crank angle sensor in 86 Nissan hardbody

Sensor detects engine rpm, and piston position. It is integral with the distributor, not replaced separately.
Testing the sensor requires complete testing of the ignition system. Use a spark tester to check for bright,. blue spark. This is called secondary spark test. If weak or no spark, test the ignition coil for proper specs of primary and secondary resistance. If coil is good but no spark, suspect the crank angle sensor. My manual gives no further information on testing the sensor. It contains a light emitting diode and a photo diode. The lights are used to show up the slots in the rotor disc that has 360 slits in it.
Good luck.

Replacedtiming belt and it wont start

run fault codes and check for crank angle position sensor problem as it is on the back of the crank pulley and is possible to damage it and rotor ( check air gap for the sensor to rotor) or not connect up the wires when finishing the job.

1991 civic crank angle sensor

The crank angle sensor use the flywheel teeth for timing at that vintage. I have had the teeth gotten chipped from years of use and cause misfire. The recommend procedure would be to change fly wheel. But that's not for the faint of heart.

Got in and started like normal, a tiny twist and it starst right up like always. Go 50 feet and start over a speed bump and it died with nonoise or warning. No spark anymore

do you still have power? if no check for loose battery cables or main fuse
If yes do you get spark ?if no check for pulse on crank angle sensor with a lab scoope ,but you can test both wires going to the coil check for a pulse while cranking
now check for all grounds on body
check for fuel relay maybe grounding

My 94 Mazda 626 quits running while I am driving, but starts right back up. i have replaced egr valve and fuel filter. fuel pump tested out at 40 PSI

Your "crank angle sensor" may be getting to the end of its life: the fault you have described is a common symptom of this failure. The sensor is easy to replace but not cheap to purchase.
