I'm having issues after putting engine in I can't get the engine to run for more than a few seconds. Its a 06 5.3l ported heads and 226/228 cam(or something close don't have sheet on me). It won't start up for while turning it over for a couple seconds. While turning over it sometimes shoots flames out exhaust and makes a popping sound then fires up for a second or two and quits. I did get it to run last night but it seemed to struggle to idle which I assume is normal because of cam swap but then it just slowly increased the rpms. This happened a couple times. I tested fuel pressure and it was at a constant 58 psi at all times.
