horze Member 35 Member For: 12y 9m 18d Posted 14/07/14 03:55 AM Share Posted 14/07/14 03:55 AM Hey guys, havin a bit of issues with car.... feel like loosing alot of power at times. Ive done quite a few things and issue is still there.. After abit of googling.. it seems like fuel reg's are a bit of a common one.. Just wondering if anyone knows how to test? Willing to test fuel pump (as it might be that aswell) and then if possible to test after reg aswell. Borrowed a fuel pressure guage of a mate.Sorry if this has been asked before.. I did search before hand.Any info and figures would be greatly apreciatedThankyouCharlie Link to comment Share on other sites More sharing options...

Quite often to split the hose going from the pump to the swirl pot lid in the tank though. Link to comment Share on other sites More sharing options...

Fuel reg is a 32.5sec job to remove. If you think it's suspect pop it out and have a look at it. Link to comment Share on other sites More sharing options...

If that's ok then you need to watch the fuel pressure at wide open throttle, right through the rev range. If the pressure drops away during the run then you have an issue.Benny.

horze Member 35 Member For: 12y 9m 18d Posted 14/07/14 09:06 AM Author Share Posted 14/07/14 09:06 AM does have a rough idle.. and it seems on start up is where the problem is at mostwhat I have done is.New plugs..coils I have tested with a meter (sparky by trade so that was easy) however one did have a hair line crack but meter showed up as fine.new inlet manifold gasket as did have a leak. new throttle body gasketcleaned inlet manifold and throttle body with carby cleaner as I was doing the inlet manifold and throttle body gasketchucked some fuel system cleaner aswell in tankhavnt done the oxy sensor yet.. but im leaning more towards fuel issue Also once tank is half full it gets worse.. towards a quarter tank left, gets bad so basically if I was to give it entering freeway, she would bog down. The issue with the fuel tank hose breaking is that also with utes or just sedans?thing is its very inconsistent when im over half a tank full. sometimes id give it and the car jumps for joy and then other times it keeps reving (no boggin down) but feels like the revs take forever to move up.. (like when u would highway gears in your diff) Link to comment Share on other sites More sharing options...

(vn's used to have a connection where the fuel rail is to hook up a pressure guage? ba's have anything like that? Link to comment Share on other sites More sharing options...
