Stagea Not Starting First Time

[Atik]

Had the car serviced on the weekend which included changing over engine oil, filter, plugs, ATF, diff oil, transfer box oil, fuel filter, fuel pump and even the front suspension!

Since then, I took the car home, parked up and decided I'd take off the AAC to inspect the condition, as I'd previously had the infamous stalling problem! I found that the idle screw was FULLY screwed in, which didnt seem right to me, so i turned it back out. The valve itself looked reasonably clean and I simply undid the screw a little to around 50% open and refitted. The car is now off the the road while I wait for track rod ends and the front propshaft, but when I try to start the car now, it takes a lot of cranking for it to turn over.

When I had the initial stalling problem, it would take maybe two or three extra turns of the engine to actually fire up. Now its around 8-10 turns before it fires up. Could my messing with the idle screw have caused that? Once the car starts, it seems to idle ok, initially around 1200rpm and then settling to around 800rpm. Its just the starting issue thats got me worried. Making so many changes all at the same time, I'm not sure which of the changes caused this problem. Once its started, if I turn the engine off and restart, it fires up first time and settles to a steady idle. So I figure its got to be either the AAC or the fuel pump not priming properly?

Any suggestions?

Did you replace the fuel filter in the engine bay? A fuel pressure test would indicate if your pump was at fault (on the way out).

Have you had a look at this thread?:

The fuel filter was changed and the mechanic commented when he took it off, there was a load of black sooty fuel that came out of it.

Back to the problem, and I think I have it worked out. I let the ignition sit at ACC for a couple of seconds last night which let the fuel pump prime up and then started the car which worked first time. There must have been no fuel in the lines to start up which is why I was initially getting startup issues when cold.
