I have a 2009 saab 9-7x that cranks but wont start. I swapped around relays for fuel pump and ecm. and it worked for a few times maybe, then wouldnt start. I bought a relay and replaced and started then wouldnt start next time. Then bought two relays and put in fuel pum and ecm spots and worked than next time no start. With the pump out but connected doesnt run but my meter says there is 12v at fuel pump supply power for 2 seconds when key is turned to acc.
