I have a 01 integra b18b:
Recently the valves went on the intake and I just replace (yes I did lapping) I threw the head back into the car and did the timing and everything on tdc.
Once I went to start it it sounded like it wasn't going to start like it was just cranking. But than it started but didn't idle at all so I gently pushed the gas down until it was idling on its own.... Shortly after 3 mins or so I turned it off and tried again shortly after but no start just cranking, than all the power went out in the car came back 2 mins later.

Any advice to why the car didn't want to start nor idle will help
