Yes, but are you using the magna ones?svo347 said:Sounds like you have computer controlling issues with the cold start rather than fuel pressure..
I have 24's & no dramas at all come freezing morning cold starts..
My cold start problems went away after the fuel pressure went up too.
Found some stuff of the net, on a CAMS tech regulations bullatin...
"Original equipment fuel injectors may be replaced with Bosch #0280150775.Fuel pressure must notexceed320 kpa"
This may be what they need to be set at to work efficiently, or it could just be a rule...
The information I posted up earlier also suggests that they were ment to run at an 'operating pressure of 3.3bar'.
If anything it will stuff my pump I would think.
The info I got was second hand though, and I am looking for more data on these injectors to confirm the information.
