How can you check the to see if it is the line or return line from the injector pump?
I pulled the 2 screws from the filter mount. Could see a very small a amount or light trace of fuel under it. I wiped it out started it. It was wet or light trace again. How and where to look?
thank you

If check engine light comes on and stays on for a few days then goes off on its own will it still store code in the memory or would discard it

Reverse worked fine before I had to do some body work, so I'm fairly certain that the problem is electrical.

Truck is fine only when it rains it will not run

When wet. No fault codes either.

the truck run fine, but if I slow down to make a stop or turn it shuts down, but will start back up with no problem.
