Why there is no spark ,car wont start

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 car has 2 crank sensors , did you replace both? One is at the front crank pulley and the other is behind and low on the engine block, above oil pan. Be sure the ICM (ign control module has a good ground, (black wire) it grounds at a bracket where the trans bolts to the engine approx at the 2 o'clock position.

Testimonial: "the check the ground was a good suggestion, i will do that at my first opportunity"
