I noticed you replace the crankshaft sensor, but not the CAMshaft sensor.
The Ignition module takes the input of both sensors to tell the coil when to energize.
This sensor should come up as an error code when you attach a obd reader.
Even if your light is not on - there may be a code. If it is not your vehicle originally, some people pull the bulb!

follow the spark plug wires to the coil packs...i believe now, you have to physically crawl under the vehicle and look at the back of the engine, to the coil packs....remove all three packs as an assembly and then remove the individual pack that you need to replace...or if you feel good enough, see if you can run your hands the back side of the engine, and remove the coil packs that way....good luck...if you need help....just call me....you in edmonton?

It sounds like you may have burned out your fusable link. It's a special wire that comes off the starter solennoid and is designed to burn off in the event of an overload. DO NOT REPLACE IT WITH REGULAR WIRE, THIS IS A LEADING CAUSE OF CAR FIRES.
You will want to check for what caused the overload condition that caused the fusable link to burn out in the first place.

Testimonial: "never thought of that great idea ill replace it and let u know thanks alot appreciate your time"

My 2000 Bonneville did the exact same thing. It's the mass flow air sensor I'm almost 100% sure this is what your problem is.
