Welcome to ZDriver!

An engine needs 3 things to start (if mechanically sound):
-Proper air
-Proper fuel
-Proper spark.

So... if you have verified spark at the plugs, it's a safe assumption that it's either not getting any fuel, or it's flooded.

Can you hear the fuel pump kick on? Have you checked the fuel pressure? Have you pulled the spark plugs to read the tips?

If you haven't done so yet, I suggest downloading the FSM from www.xenonz31.com/reference

 

im pretty sure it is the plugs then its got air and fuel the pump and the filter are brand new all hose's were replaced i checked all the spark but the plugs cause at the time i didn't have the tools on me to check just got 6 new plugs and i am most likely installing them later today or tomorrow if i have time
