This is happening on my server too. Tried everything mentioned in here, and the new version, still not producing anything, but still runs and uses fuel.

Having the same issue.. Works fine at first then nothing at all.. 

ok so this was what ended up being the issue I was having, check the pm number in the bpj config file. if its zero, change it to like, 5 min and 5 max or something.

same issue for me and pm number are not set to 0...

Same here, tried the refill command. Has the farming update broked it maybe?

I have the same problem but backpumpjack.refill helps. Though I need to run it after every server restart.

same issue here

backpumpjack.refill will say it has refreshed 1 quarry source but nothing happens

Merged post

Did some more testing and reloading, put the pM to min 5.0 and max 5.0, reloaded the plugin loads of times, reloaded my other plugins like GatherManager alot of times then threw some more survey charges then ran the backpumpjack.refill command and now it only works on new placed pump jacks. The old pump jacks dont work.

1.4.8 - not producing crude oil.
