If you believe its the injectors try a can/bottle of injector cleaner and use a can of carby cleaner to lightly spray around the injector seals to confirm no vacuum leak as the age of the vehicle would suggest they may be.Valves is also a good idea to reset as over time they do tend to sink into the valve seats and the valve clearances become too tight,this is a common problem with a lot of engines.

Power on but my 2000 ford ranger will not start


Replace battery terminals and/or clean battery posts. Horn and radio don't use as much juice as starting. Sounds like a lack of amperage or electrical pressure to push the starter motor. Also check battery. Needs 12 or more volts and about 600 or more cranking amps.

Ford ranger 1988 pistons are stuck


Why are they stuck? Is it from setting and there rusted up? or are they sezed up from lack of oil? If its rust just take some trans oil and pour some into each spark plug hole and let it set over night, and then put a socket on the harmonic and turn back and forth until it frees up. If its lack of oil its my best guess you better look for another engine.
