My boyfriend tried to start the car, it wouldn't turn completely over and after the fifth time trying to start, it popped and then puff of blueish smoke came from under where the air filter is located

I have a 95 roadmaster i've replaced fuel pump, filter, IAC valve. I drive the car for 30 minutes its good. Turn it off and come back it cranks up but when I pull of it acts like its out of gas. It won't crank up until after 30 minutes. What could it be?

Egr valve replaced, spark plugs replaced, Spark plug wires replaced. fuel system cleaned. I noticed the tin round piece on the bottom of the old cap was missing. Could this be caught up in the system ?

their is a ping. And the transmission little rough when it does not run around 190. What would be causing not heating up to normal running temp ?

Could this be electrical? How do I investigate the cause?

I completely have no brakes.

I have a 1996 Buick Roadmaster 350 LT1 5.7, I am having some issues with the vehicle idling rough and seems to be missing. When I turn on the AC the car runs a little better and sometimes after shutting the AC OFF THE CAR SHUTS OFF.I went to AutoZone and had my car put on the computer and I got a EGR code P0400, Mass Air Flow code P0100, and a Catalyst code P0430. I replace the EGR, and mass air flow sensor, and my car is still doing the same thing. I was also told I may have a leaky water pump. I just recently installed new AC DELCO plugs and wires and a new air filter. Any ideas on what to try next or what could be my problem?
