I got it running now. I checked relays even ran jumper from battery to fuel pump one to check ground for pump and to to run it. So I unplugged battery for thirty minutes then reconnected turned key to on for two minutes then turned off and then back to on with fingers on fuel pump relays they both click and car started. So I know with disconnecting battery I reset ECU what causes ECU to trip? And two door locks stopped working also. is this anyway connected or just poor timing?

Your description sounds like the immobilizer circuit is tripping and shutting off the fuel supply because it thinks you are stealing the vehicle. Does the security light or anti-theft lights come on? It could be that it doesn't recognize the key or there is a fault in the system, it could also explain why the locks stopped working. You would need to connect up an OEM level scan tool and see if the system is being triggered and by what. Then work from there.
