Problem with the ignition of Caterpillar P5000 Engine Nissan K25l

Hello Guys

I have some problems with a caterpillar forklift model p5000 with motor nissan k25l that use GLP

I was make a maintance of the vaporizer, throttle body and reductor, too calibrate the valves.

When i try starting the engine, this won't start, i revised the vaporizer and the modular ignition coils but this appear to well.

The GLP arrives to the regulator, because if retired the injector, when the key is the on position, the gas out for here, but i have a doubt, the injector is a proportional valve or a two states valve (open-close), because i measured the voltage in the wires of this injector and i found 3 volts more less when the key is in the ON position, this is rigth?

I was making a test, i disconnected the wires of the injector and gave starter to the motor, at the same time plug in the wires to battery and the motor try run, but appear that if connect more the the injector to the battery the motor is drowning and the otherwise dont try run.

I think that the problem is of the injector, or the some part of the reductor, but i have doubt with the ECU and Throttlet body

What do you think about this? Some of yours have a service manual of this motor? for me is very important

Thanks for your time, and sorry for my bad english, i am learning

PD: The reductor is very similar at this http://a248.e.akamai.net/origin-cdn.volusion.com/kxtj9.rx7yg/v/vspfiles/photos/A6610-GX11A-2.jpg

What i used to do all day now takes me all day to do.
First of all check all wiring on engine for shorts or breaks. Special attention to wire breaks at connectors. Turn on keyswitch and listen for a click meaning the LPG lockoff is working. If not then check for broken wire on the LPG pressure sensor then relay ( second going inboard) next to fuse block. Then listen for LPG being dumped into throttle chamber with KOEO. If fuel is being dumped then an injector holder is probably needed if the main injector isn't stuck open or stuck assist injector. Cut switch off and listen for a high pitched sound with a little clicking coming from throttle chamber for appoximately 3 seconds. If throttle chamber is not making a sound then check fuses for ETC and relay for ETC. Also check fuse thats located on injector pigtail. If all else fails then contact your local Cat dealer who should have the software to get readings from different sensors and have you up and running in no time.

No pongas corriente directa al inyector de gas, ya que lo puedes quemar.Mejor si dudas de que el inyector este funcionando correctamente,ponle spray para limpieza de carburadores y dale marcha, si con esto arranca entonces ya sabras que tu inyector esta fallando.
