1994 Chevy Beretta car trouble

Could be a couple of things, but mostlikely the crank position sensor is your culprit, you could have a problem with gas or spark, your crank sensor has to do with spark. You should verify that you have good fuel pressure that will tell you if your fuel pump, fuel filter, and pressure regulator are working, and the spark will tell you if your wires. Plugs coilpack etc are working. I will send you some video on how to check these things
