Put motor in after rebuilding it
Ran fine no issues no CEL till 550miles (problems listed below)

Okay so I have been having some starting issues, turn key to on position engine light goes off and then go to crank it don't do nothing but when I let the key go back to the on position.
The main relay starts clicking, the spedo goes crazy up and down and then after that goes on for a couple seconds it re primes the fuel pump ready to crank again.

I have tried replacing main relay with new one, took starter off had it tested came back good, tested all fuses with test light, checked all engine grounds like thermo housing, and I have spark, correct fuel pressure "when the pump primes."
I can still pop start my can and it run fine, but the only issue is when I do that is that the temp gauge with move in sync with the rpm gauge from normal operating temp being idle to about 3000 it reaches the top hot mark. I know it's not over heating because at idle the temp is normal and it will stay normal no matter how long it sits idling.
I have no idea what to check Next
Please any direction will help any feedback. I have never had a issue like this with a honda. I have done multiple swaps in the past. First time having to search out help on forms. Thanks for your time.

 

Check battery?

 

Check battery with load tester? I assumed the battery would be ok considering it pop starts. But I will get a load tester on the battery shortly.
Thanks for the reply.

 

Battery tests good. Noticed I filled my tank from quarter to full, I didn't have to pop start it after refueling. Could a fuel pump cause the symptoms I'm experiencing?
