When i start my car, i must crank 5-7 times when it fires up. i thought that it is sth do to with fuel pressure. today i checked that. When i prime fuel pump (ignition only) the fuel pressure stays 0. when cranking few times it rises and start up. With running engine its 2.6 bars. when turned off its 2.6bars and after 10 minutes it rises to 3 bars. i think slow start is related to the 0 fuel pressure with ignition on. I can hear the fuel pump priming. I primed 5 times and nothing showed on the gauge. Can somebody help with that?
