Is there any reset proceedure after replacing ecm? I have the same issue , Startes but seems way to fat on lp. If no reset is the only option to replace vaporizor unit ? code also e 38 Thx

the time you spend rebuilding this vaporizer and trying to get it setup correctly could have been minimized if you had just gotten a reman vaporizer(comes preset to correct setting already).

Good luck and fyi, you just assumed the liability yourself instead of the mfg.
doh!

Thanks for all the replies and sorry for my late response. I finally got to this project again recently and decided to rebuild nikki Vapouriser. Rebuild went great but as someone had mentioned the injector body has a relief valve that remained stuck open. I have removed the plug that covers the adjustment screw to remove the needle valve to clean and reinstall. I am not sure as for adjustment procedure for the set screw but i believe the injector inlet pressure while running should be about 5 psi? Is that correct and do i use this screw to adjust this pressure. The truck is now running good but im not sure how to plug the set screw opening as it had a welch plug that i had to destroy to remove it. Any Input would be greatly appreciated
Thanks

ralphspa;
I would suggest to you, that you review, read and understand the disassembly, clean, rebuild, adjustment and reassembly instructions for the tamper resistant vaprizer - regulator. If you have not been certified to perform this work you would be advised to give this task to someone who is. You need not accept some serious Canadian legal issues by not doing so.

Could also be a relief valve in the injector holder stuck open,if the regualtor fails,sometimes one of the two relief valves will stick open and stay open even after the regulator is repaired,remove the injector holder and the injector and assistant injector and give it a cleaning,sometimes can just tap on the injector holder with a small plastic faced hammer and will be enough to free the relief.

cat has remans available for less money
save yourself about 300 bucks and get a reman

one other thing to consider also is if the vaporizer over-pressured the main injector housing it could have damaged that main injector as well. If you hear lpgas rushing into the injector body,... this has occurred and the main injector will need to be replaced as well.

Does this have the NIKKI Regulator in it?
Need to rebuild the whole vaporizor,is a couple other diaphrams and a "flapper valve" as i call it that should be replaced also,then will have to set the pressure to 4.5 PSI.
Have an email to post in your profile?? Have to post as mine is as site strips out readable address's.

hi,

This failure relates to a propane gas leak just change the parts of the vaporizer and ready packaging or check if any of the hoses to be leaking water and not reaching the vaporizer
