Hello all,
As I’m sure you can guess I’m new to the site and have been reading the forums for years. Figured it’s about time I join up and get in the mix.
I have owned multiple squarebodies in the past (83 K20, 350/465, 55k miles)(79 k5, 350/465, tons) but I currently have a 1991 v3500 454 4l80e that I bought from my brother. I went with him to get the truck about 7 years ago and always wanted a crew cab. He finally decided to sell to me (lucky I knew what he paid for it) so I brought it home.
Been an adventure up to this part. Fuel pumps weren’t coming on so swapped the FP relay, oil pressure sensor, tank switch and finally the tank selector valve and success!… sort of.. truck will run for about 6 seconds and dies.
I am currently in the process of removing both tanks to replace tanks and pumps, as the aux tank has a rust hole. I am looking at the other posts about the tank straps and attaching to original bracket.
The only other thing I recall about the truck when my brother bought it was that the truck moved when cold but when the trans warmed up it started acting like the trans was slipping badly. I haven’t been able figure out what that’s all about but I figure if I get the truck to run for more than a handful of seconds, I’ll try to flush the trans with a new filter and see what happens.
Anyways, if anyone has any page links to help point me in the right direction I’d be grateful.
Looking forward to working with yall, thank you and God bless
Rhett
