First problem:
My sending unit in my midship fuel tank is constantly reading full, and on hard acceleration, reads really full. Any thoughts? I haven't ohm'ed it yet.

Second Problem: The truck is more and more often not shifting out of first. Used to, I could let off the throttle and then get back on it, and it would shift. Now, I have to take it out of gear and put it back into gear before it shifts. NOTE: I've only noticed this issue during longer accelerations when I'm shooting for fuel economy over horse power. Thoughts?

 

i dunno about the shifting, but my fuel guage is doing the same thing, Ive been told its a bad ground to the sending unit. waiting for warmer weather to work on it, all i have is a shade tree and no shop......
