gday all just would like to know if there is a section on here on testing items when my calais won't start The problem I have is the car cranks but won't idle it starts for a second running rough then stalls?? Just would like to know if anyone's had this on here and found a simple fix on what the cause was.... ie injector plugs or loose plug somewhere I can start searching. Cheers guys

Could be a few things mate. I would start with your fuel pump, turn ignition on to see if its priming and check your airflow meter.

The three things needed to start a car are Fuel Spark Air Start by pulling fuel hose off to rail and see if you have fuel when cranking! 2nd pull out a plug, leave connected to lead and see if you have spark!

Did you end up getting your VLCT started CALTURB? I have exactly the same issue. Doesn't start. If it does runs for a few seconds then stalls. Its a manual. Have gotten the injectors cleaned, replaced CAS and bearing, have spark and fuel. No errors for CAS etc from the ECU codes. Abit stumped

I had a similar issue and it was the in tank fuel pump.

Hey Oliver, thanks. I have replaced the in tank fuel pump and have fuel to the rail. I also have spark on all cylinders and injector pulse on all injectors. If I spray fuel into the plenum, it starts for a second or two then stalls. It's unlikely all or most injectors are stuffed as they were tested 6 months ago and just put on recently. Plugs aren't wet, just have abit of soot on them. Have power to the coil and power transistor, unless power transistor is stuffed? Still seems like a fuel issue. Will try some more tests

I replaced the external fuel pump and the car started. Had no fuel pressure as the pump wasn't working
