Car was misriring parts store said it was the plugs,wires, and showed crankshaft sensor was going bad. Changed all, now my car want start.sounds like the firing order is hooked up wrong, but i have checked it 10 x and its right. any answers for me. oh ya fuel pump is working and battery has full charge
If the store pulled the codes and it had a code for the crank sensor, the real problem could be a bad cam sensor or a problem with the crankshaft. The crank sensor "sees" a mark or magnet on the crank and sends a signal to the computer. The computer takes that signal and compares it to the cam sensor to start the engine then runs off of one or the other. It sounds like the computer is not seeing the two signals match up.

have you gotten your fuel injectors checked? fuel injectors seem to go bad on later model v6
SOURCE: 2000 chevy venture doesnt start
Not the IAC, or MAF, or 02
Does the Van Crank over?
Have you checked the IGN Relays? 1,2,and 3?
How did the Battery test out?
Anything below 11.9v battery is dead.
So I suggest that you do not throw any more parts and check the battery again.

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.
