fuel pressure regulator how hard to change

[mynameisearl]

just wondering how hard the fuel pressure regulator is to remove from a 99 vt, i've gone through everything else trying to work out why my car struggles to start and it's about all thats left

is your fuel pump priming before start sounds a lot like when they dont prime and you have to get the oil pressure up so the oil pressure switch fuel pump backup turns on

yeah mate its priming its brand new, so is the fuel filter, the battery, reco'd engine has only been in for about 2 months has new rings, lifters & bearings. everytime i take it to a mech they tell me its something different, one did a fuel pressure test and said the fuel pressure dropped off to nothing as soon as the car was turned off, he reckoned that was my fuel pump but i put a new one in and it still doesn't start any better. I was thinking the fuel pressure regulator might have been why the fuel pressure dropped off so quick?

yeah probably mine sits at 40psi for ages when i turn it off.easy to replace its held in with 1 allen key i think.easiest way would be to remove the fuel rail to replace it but should be able to reach it in place

just picked up a new fuel pressure regulator from Holden today for $90. I have the same symptoms as you and have done the same things to try and fix it, so fingers crossed that this will fix it.
Easiest to partially remove the fuel rail (don't have to disconnect fuel lines), might as well do the inlet manifold gasket while you are at it, which is what i'm doing.
It is held in by a circlip, so circlip pliers will be very handy.

how did you go, did it help at all? I'll be changing mine this week. I had to order one in through repco for $64, looks like its in a pain in the arse spot to get at too. OH anfd for anyone wondering its held in with one of those clip ring things

Mines a 98 i hafta replace the whole rail

Any updates on weather changing the fuel pressure regulator fixes starting problems?

[jazza15]

it didn't fix mine If your car also coughs and splutters when you boot it (accelerate hard), then it could be your problem. It's back to the drawing board for me.
As for Vt's having to replace the whole rail?? I thought all of them are removable?
