Could be ignition switch, camshaft position sensor, poor connection at pump etc. You will have to troubleshoot it a bit more. When you say relay do you mean aftermarket pump relay? Have you tried unrelaying it again to see if it then works?

Camshaft position sensor is not old, connection on pump is good, it is the orginal fuel relay under dash is klikking, i have one relay i have soldering it(test only), then it is not klikking but engine is stopping(same problem), can drive for 14 days no problem And can drive for 2 Minut and run and stops, drive like 500meters and stop and start up again.. i cant see something wrong,
