so i purchased my 2003 series 3 gu zd30 patrol 3years ago now and have some good motoring out of it , when purchased it had been fitted with a D_GAS gas injection system .On purchase of the gu the previous owner told me he had it fitted in 2008. he used gu to go from perth to darwin and the kimberly trips
and when back in perth the fuel pump shit its self so he had that rebuilt . From the time after the fuel pump rebuild the d-gas system then started to play up (were his exact words). so i stopped using it and being the installer D GAS DIESEL ENHANCEMENTS in malaga perth has gone out of busisness had no other option to stop using it . he told me that he took it to a nuther gas mob and they told him the fuel pump rebuild was the issue and it all needed re calibrating
So i have never used the system apart from a quick flick of the switch to see what would happen?
What happend was it ran extreamly rough and pinged its head off and shook the hell out of the car .
SO the question is what to do its been on the car for 3 years and hasent been used still with 20L odd of gas in tank still im wanting to get more room back in engine bay so i can fit catch can and nads stuff in there and have new redback 3inch exhaust to fit as well (exhaust has been modified to fit gas tank)
so do i remove and try to sell? (what would it be worth ? have recipts from previous owner of $3795 when fitted)
or do i try to get it looked at and keep ?
I anyone out there has any experiance or ideas feel free to comment
