Discussion:
No fuel after battery lead replace.

Good day,
I have a Toyota 42-5FG25 (S/N: 405FGU25-78696) with a 4Y engine under the hood. It's running LPG.
Due to corrosion, I had to run a new positive cable from the battery to the starter. After doing so the relay that controls the fuel lock-off (The odd little cylindrical one behind the battery) is no longer getting powered when the ignition is activated. If I power the lock-off directly, the truck starts and runs without issue.

I will mention that there are two additional leads coming off the positive terminal; one of which goes to the loom behind the battery but is energized as far as I can check. The other lead goes to the instrument cluster on the steering wheel column.

I, unfortunately, do not have an electrical wiring diagram for this machine, I wanted to see if anyone had any ideas as to what might have happened.

Thanks in advance!

Might have a fuse able wire one of the 2 little wires or check connection on plug by battery. Had a issue like that several years ago

Brothers Adolf ("Adi") and Rudolf ("Rudi") Dassler split their shoe company after WWII due to a bitter feud, and established the rival companies of Adidas and Puma. Their personal animosity and business rivalry divided their German hometown Herzogenaurach. The town became known as "the town of bent necks" due to the intense loyalty to each brand.
