Put in new fuel pump and it still doesn't start, no power to pump. whats wrong?

If the pump continued to run after shutting off the car you fuel pump relay was probably staying latched. I would replace the relay as well based on your info. Along with the pump the fuel filter should be replaced too and fuel pressure should be checked. Make sure your ground is good also.

check your crankshaft position sensor. fuel+spark+compression+timing=ignition.

how are you determing there is no voltage? does the fuse have voltage? the gray wire is the power for the fuel pump. can you by-pass the relay and still no power? have you checked for voltage at the pump with relay by- passed? I suspect the pump is bad.

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.

1. does it turn over? if so, strong, or weak? 2. did you replace the fuel filter? 3. coil packs, or distributor (pack(s) can be tested) if distributed check cap and rotor, replace coil, but first check starter relay - 4. Check all ignition fuses, starter fuse - (along with relay{above}) 5. Check all connections from battery - positive, negative etc.
Please let me know if you need further assistance.

if you have no fuel when the and it just wont start it may be the crank position sensor if it's the 4.0l engine the crankshaft position sensor is on the top of the transmission bell housing on the driver's side and can be accessed from underneath the vehicle and is plugged in at the back of the intake manifold

most common problem with these civics are the rotor and ignitor. i would reccommend starting with a new dist cap, rotor, and ignitor.

What you need to do is drop the fuel tank and put a new fuel pump in it. I would drain the gas and put new gas in after you get the pump changed.

check in trunk for a fuel cut out switch, it shuts down fuel flow in case of an accident

It is most likely the fuel pump. pouring gas down the throttle body will not start it, it will just flood it. try spraying a carb cleaner in the throttle body in short 1 or 2 second bursts while some one else cranks it, it should start.
