how do you turn injectors off on EL 4.0L for LPG install

I cut red/sliver wire at fuel rail square plug - this i believe supplies 12v + to injectors and ISC

I also spliced new feed for ISC but now car wont start when on LPG

I THINK THERE IS NO SPARK - does this wire also feed the coil and /or anything else

i thought of isolating the injectors at the ECU - CUTTING THE TWO GROUND FEEDS at pins 58/59 and wiring in relays

whatcha reckon??

ummmm...disconnect battery maybe ????

From memory, the 12V at the plug branches off to the injectors, ISC, TFI, and coil (maybe not all, wiring diagram is to far away).

I guess u can either cut the 12V closer to the injector run and patch as needed or cut the switched earths. You could also unplug the injectors.

Im sure someone who has done it will post soon enough though.

oh,.....u mean switch the injectors off when gas mode is turned on....sorry...please disregard my previous post.....

its gonna be DUAL FUEL so unpluging injectors is not an option - i want to isolate when LPG selected

i reckon it also feeds the TFI module - this would account for the "no spark"

i think im gonna reinstate original wiring and switch them thru 2 relays at the ECU
