Car Wiring Schematics

1994 chevy beretta 2.3 liter quad 4. I am losing spark at times. Anyone know where to get Wiring Schematics?

when there is no spark you can turn the key multiple times and regain spark. I tried changing out modules, crank sensor, coils, computer and fuel pump. the car may shut down while driving and without warning or it may run fine and the next time I try to start the problem occurs again
