2009 prowler 550 cranks but won't start.

Hi guys, just bought a 2009 prowler 550xt. It wasn't running. Pulled the head off and it had dropped an exhaust valve. I bought a new piston,gasket set and a used head. Got it all back together was missing 2 of the top valvecover bolts. I cranked it over and after a couple tries it fired up and sounded good. All the sudden oil started pumping out of one of the missing bolt holes so I shut it down. Got two new bolts and now it will just crank and won't fire up. I have spark. Fuel pump works every time you turn the Key on. All the fuses are good. Did both tests on the tilt sensor and sensor plug and both test good. Disconnected the battery and let it sit for 15 minutes re connected and still nothing. It will run on carb cleaner as long as I feed it. Fuel injection not working. Got Power to fuel injector when key is on. No ground. Any ideas?
Thanks

Does the fuel pump cycle? Need to see 43 psi on fuel. See if the pump is pushing fuel to the injector.
