well well WELL!!!
it only runs !
i inserted my new kit into the reducer , noticing in passing that the small spring looked a bit rough on the end as if it may have at one time been a larger spring..
then put in on the car ,fired up the xp laptop ,which WILL talk to the ms2 ,and tried to start it , fuel pressure was 15 psi.
bit of a stutter ,then nothing much ,so increased inj time to 2.8s .still nothing ,so started increasing req fule in steps ,got to 20 ,and off she went ,finally got it to run quite responsively on req fuel 17 .
at this point the header tank started to blow off .... odd i thought not hot ...oh oh ,blown head gasket ? bit of investigation later ,lpg in water circuit ,gasket on reducer not sealing .
also noticed fuel pressure had crept up to 25 then 40 psi ,so thats not working either .
so 2 steps forward and 1 step back .
took the rducer apart ,noticed the orange gasket on the water side is slightly textured ,whereas the original is smooth , so either they used some sealant on the original , or this new gasket is poor.
ref the gas pressure ,the small spring that sits behind the gas valve , on my one is terminated by a simple break in the large coiled end ,this creates a tilt on the spring when it has the backplate on it ,is this normal ,or has the end of the spring broken off ? this may explain the creeping pressure rise and there would not be enough force on the pintle to seal the gas .
on the good side , at least i know for sure my injectors work with my resistor pack .
