Won't start - Technical Troubleshooting discussion in Forkliftaction's forums

Cat Lift Trucks (& Caterpillar) P5000:
Won't start

I have a P5000 that will not start, had a bad vaporizer so replaced with new one.

I'm able to get it to run out the propane in the system if I remove the injector.

If you continue to try and start it with the injector in and the tank open it will frost up the vaporizer, I had a symptom close to this a few years back on another P-5000 and it was a bad ECM but I got codes on it. Could this be a bad vaporizer?

Does anyone have any ideas, also does anyone know what the voltages should be at the injector?

Thanks,
Leigh

First thing i will ask is what was wrong with the last vaporizor? Codes??? E-38?? What is the fuel pressure coming out of the vaporizor now,is it around 4.5 PSI?? You say it frosts up,is there suffecient coolant in the system to get thru the vaporizor,good coolant flow thru it also???
I would take the injector and injector holder off and clean them out good(tar,debris),also clean the "last chance" screen this gets plugged with tar and debris especially after a vaporizor lets go.
