Could be a couple of things, have you run low, or run out of fuel lately, if so there is a good chance that you picked up trash from the bottom of the tank and clogged your injectors, or your fuel pressure regulator, if you are getting the correct amount of fuel pressers at the fuel rail then i would recommend popping an injector out and have someone turn the key on, if you aren't getting a good healthy mist out of the injector, then chances are they are clogged, and depending on how clogged they are you may need to replace them, i worked as a chevy mechanic for many years, and saw problems like this all the time, the placement of the pumps in the tank was not the best design, so when the tank gets below the 1/4 mark the pump is more likely to pick up trash from the tank, also the pump is liquid cooled and needs to be submerged, and below a 1/4 it is out of the fuel, this makes the pump run hotter and causes premature failure.

Check for the solenoid from the truck's starter.

It cranks, but why doesn't it always start?

What is year--make--model and engine size? The basics, if it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs, gasoline engine. If spark everywhere, use a gage and check proper fuel pressure, also check for fuel injector pulse. Check cylinder compression.

Can you check for applicable trouble codes?

I have a 1987 ford ranger the engine turns over but it wont start

Spark at plugs? Fuel filter? Pressure on injector delivery line? Pressure relief valve? You may be able to measure fuel pressure at the pressure relief valve location. and return line. If you have spark, I'd say it's a fuel supply problem

99 bravada 4.3 cylinder 4 misfire/ cap,rotor,plugs,wires all good

If you are sure your spark is good, you need to verify compression at that cylinder, and fuel (fuel pressure from the pump as well as an injector pulse, if these are good, swap injector with another cylinder to verify the injector, if you have multi-port)

Good fuel pressure, already replaced ignition module, distributor cap & rotor, plugs and wires

So you have fuel pressure and spark ? if so, what about injector pulse (noid light)

Engine turns over but will not start

Check the distributor and timing order to make sure it has not jumped at all from a timing malfunction.

1997 Chevy K2500 will not start wet wet under hood.

Sorry in the delay getting back to you.......on....Check for injector pulse.
Look into the throttle body......where the air goes into the the top,middle of the engine will have to remove the air filter......and look for fuel spray from the injectors...."when the truck stops running on you"....If no have fuel problem which may lead to the ignition module or dist pick up.
No RPM spray.
If spray is present......check for lack of spark which again may lead to the ignition module or dist pick up.
Just carry a spark plug with you and pull a wire...insert plug,,,ground plug and look for spark.
Let me know what you have found.
