Why does your 1993 Cavalier crank and have spark and fuel but not run?

your 93 cavalier may have a fuel line blockage which prevents the fuel from gettin to the engine. first i would take off the fuel line to the injectors then have somebody crank the engine for like 2 seconds and if the fuel doesnt spit out of the fuel line or barely comes out then you have a fuel line blockage!

check your fuel pressure with a gauge and make sure its within specks, if its low, could be your regulator,

another option is your crankshaft position sensor, if this little unit is done, you get what u got!

you can check your fuel pressure without a gauge,on the fuel rail there is a release valve, looks like a bike tire valve, pop the cap, with safety in mind depress the stem, to c if fuel comes out, member this should b under pressure and may spray, now turn the key to the on position, listen for your fuel pump to kick on , then depress the fuel rail valve again, careful you dont want a gas bath!!!find out from a garage how much the pressure should b and use common sense, lil pressure lil fizz, big pressure big squirt!!! !!!Plugz!!

Possibly the crank sensor or the coil pack is dead. But with a dead crank sensor you also get no spark, no crank. No crank equals no fuel delivery.

If you mean will crank, but no fire, then check for spark and fuel. If you mean will not crank, then check the wiring and the starter.
