hi, tested fuel flow at rail into bottle, all good. Tested resistance at TFI plug, all good. Tested voltage at TFI plug, no good. Tracing back wiring to find fault. Found crappy soldering at big round plug on firewall; black wire soldered to the large core red wire, feeding to LPG relay, may be split, got to trace the black and see where else it goes.

Thanks Dave

This XG has Smartlock and reading the T.I.Performance guide should only be an issue if BCM doesn't have Smartlock as per EA EB. If you are doing the XF I'm thinking you will need a Smartlock code generator (bypass gizmo Ebay $115) or use ECU, BCM and loom from donor car.

Thanks All, Hi Dave, yeah doing one thing at a time. I am looking at the replacement changeover fuel pump relay and connector: the new set has five wires on the connector where the old and loom had only four at a loss of what to do with that lot. The pinouts appear to be same with the exception of pin 32 which is 'recirc cabin air' on the XG and 'LPG cut out or OFF' on the EL ECU. Thanks

Hi all, after the ute sat idle for twelve months whilst I was studying, I started back working on it last month. I fitted the EL ECU 6TBA, keeping the log manifold for the time being, but reckon I've screwed up as it turns over, fuel pump primes but doesn't fire. I had reset base timing to 0 degrees btdc prior to taking out old ECU thinking this was correct to change to EL ECU. I looked at the fuel pump relay after checking it at the diagnostic white plug under the dash. The relay connector was heat distorted and found the LPG feed spliced into that circuit so cut that away, fitted new relay and connector plug. All fuses are good, as in engine bay five fuse block (black cover) behind battery and under dash fuse panel. Checked coil power plug and that read okay too. Battery has been fully charged numerous times for trouble shooting. Smartlock light blinks as normal when car is off, goes out when cranking and the interior light lights when door(s) opened. I checked the fuel to the rail and I had fitted them arse about so fixed that. The changeover relay and connector for the fuel pump has five pins and five wires on the connector plug, the original only had four and I don't know what to do with the fifth wire Connector plug is PAT Premium CPS-031 and relay is also PAT REL-001. There are only four wires on the loom for the original connector. I am planning to change dash/bcm/loom(EL) etc to XH to save splicing looms and then fit the BBM going without LPG keeping the 6TBA and auto box for the time being. Next days off I am going to check dizzy at number 1 tdc, just want to get it running again, it was running set up as XG prior: Log, XG GLi ECU and dual fuel. any input would be great, thanks.

Hi all, quiet year with no time to play with toy. I had fitted a secondhand I6 4.0 from an XH XR6 to my 94 auto XG keeping the log manifold and running XG timing. Now I have changed ECU to EL XR6 6TBA after setting base timing to suit. I have spark and fuel, the fuel pump starts running when ignition is turned on and smartlock light goes out. Interior light works too. Engine turns over well, but does not fire. Could it be dizzy or timing problem? I have checked wiringto the coil and zapped myself checking plug lead 1 both good so I figure coil ok too. I am yet to check injectors are pulsing as my youngest is finishing exams and my arms aren't long enough to reach them when turning over engine. Fuel line is connected correctly. I am not convinced it is a smartlock issue after reading the TI Performance diy guide. Just after some troubleshooting input from those who have done this before. Outback Jack mentioned in an older post that EL engine won't run without a MAF sensor, and XG has a MAP sensor, could this be an issue? Thanks for any help.
