Low pressure light - Technical Troubleshooting discussion in Forkliftaction's forums

Unicarriers (& Nissan) MAP1F2A25LV:
Low pressure light

Had a no start this morning vaporizer was frosty so I rebuilt it. I got it to start but couldn't give it any throttle without the low pressure light coming on so I rebuilt it again and got 3/4 throttle at idle but couldn't give it any in gear without the light coming on. So now I have swapped the vaporizer out with a used but working one and now at idle I have full range of the throttle if I press it slowly and in gear I have 3/4 throttle but once it hits the floor the low pressure light comes back any ideas what could cause this thank you

Not sure if this is fixed but i would check for
-double oring on the lpg tank
-electric lock off filter
-last chance screen

Of you had a scan tool or was able to get into the dash to see the lpg pressure sensor read out it would be easier to determine the issue.

The lpg light is also know to come on if the lpg temperature sensor reads to cold or is defective.
