My 1996 Dodge grand caravan is not starting up but will turn over. I have installed a new crankshaft sensor, new fuel pump and still nothing. Coil pack is good. No spark from harness connecting to the coil pack. What can it be?

Hello fellow auto mechanic. Let's take one step at a time .Your engine turns over because your starter is connected directly to your battery.It's possible that the crankshaft sensor was the the problem, but NO. Also new fuel pump well maybe but not yet. There may be more to this story and as always not what you may have done but what you don't know you have done.
First when you put your key into your ignition and turn to on you should here a noise at the back of your cars fuel tank. The sound will be a whiiiirrrrr sound indicating that your fuel pump is doing it's job and pushing fuel to the engine. It will be a very significant sound and you will know it when you here it. If this doesn't happen go to your power control center under your hood on LEFT side open it and you will find a relay for your fuel pump. This is an easy check because you can pull the relay for your horn LABELED the same, and use in place of your fuel pump relay to see if you can start your car. If this doesn't do it ,one more test look at the relays and find the ASD relay this is the main shut off to your vehicle. Now if this doesn't work it is very possible that you or whoever replaced your fuel pump may have crimped some wires or even forgot to hook up the the plug to the pump. This kind of stuff happens all the time, that's why people are always asking questions.Check the simple stuff first, and I believe you will find your problem. It's probably something very simple , don't get discouraged.
One more thing , why are there so many 96 Caravan problems? Please get back to me on the above and let me know if I have helped you. Don't forget to vote and GOOD LUCK.
