I have a 2001 dodge durango and we just replaced evrything on the engine but we can't seem to get it started. How do I know that the timing is right?

Hello and welcome to JustAnswer!
Sorry for the delay, I hadn't gotten notification of your request.
When you turn the key on do the fuel gauge and voltmeter work or do they stay down?
They are working
When you first turn the key on do you hear the fuel pump run?
Have you checked for spark?
Have you checked for fault codes?
Yes brand new spark plugs work just fine and no codes
Yes fuel pump is running
What all was replaced?
Did this start after any work was done, accident, etc?
Did it start after getting fuel?
How did you check for fault codes?
This started after we took the engine apart and replaced all the gaskets, spark plugs, seals, timing guides, tensoner, harmonic balancer. Cleaned the block. Already had gas in it. Yes checked for codes and there was none.
How did you check for codes?
Where did the replacement parts come from?
Exactly what happens when you crank the engine? Does it crank but has no sign of life?
With a code reader under the dash. It just keeps trying to crank but no sign of life. It had signs of hope once but now it just keeps trying to crank. Got the parts from auto zone
Do you have a test light or voltmeter?
I have a test light
Great. Attach the alligator clip of the test light to battery ground and unplug one of the fuel injectors or coils. Probe the dark green/orange wire and turn the key on, see if the light lights up for 1-2 seconds. Then crank the engine and see if it lights up while cranking.
Yes it does
Now move the test light alligator clip to battery positive and probe the other wire in whatever coil you are in, crank the engine and see if the light flashes while cranking.
yes it does
Now let's do the same thing at any one of the fuel injectors and see if it flashes or not.
It flashes there as well
Do you have some carb cleaner or starting fluid? If you do I'd like to spray some in the throttle body while cranking and see if it will fire off of that.
okay I did that and all it does is crank
It does sound like cam timing is most suspect then. We have spark and fuel but for some reason it's not starting.
How did you set the cam timing? Did you have a manual?
We set it by what was in the manual
At this point you're either going to need to go back in and check cam timing again, or another option may be to check compression and see if you can see something there. If you can verify compression is low then you know you need to go back in and check the chains. You have spark, fuel pressure and injector pulse, and the problem started after the timing chains were off so the problem is almost surely cam timing.
You're welcome! Let me know how it goes!
