Yep I have been around since last year but , not on the forum as I have been constantly fixing this LC5
The strange thing about love, is that you never see the pitfalls ....
To use your terms MD, I too bought a “pup” with my 80, but it was at a “pup” price.
It was sadly neglected, but at least the previous owner was openly honest about that. When you go in with your eyes open, the only way is up. But when you’re led to believe its in good shape, it must be very disappointing.
The love bit is something else. I love my truck and its been a bit like taking in a bedraggled stray animal, nurturing it and it pays back with rewards.
Over the 11 years of ownership, I’ve now got it into reasonable condition, there’s still stuff to do and always will be, but step-by-step we’ve got there, and its a beast!
Hang in there, but don't do it begrudgingly. Best to sell it and move on if that’s the mindset that develops. If you do “love” it then press on and get it ship-shape.
I don’t know the 100 so can’t comment on a weak fuel pump, on the 80 there’s a gauze strainer on the end of the scavenger tube in the tank, and that can fur up with dirt and slime which might cause your symptoms. It’s a simple fix on the 80, removing the “sender unit” from the top of the tank, giving you easy access to the fuel gauge sender and the strainer.
Best of luck and keep posting your problems, there’s usually someone to help.
If you put all your truck details into a “signature”, then everyone will know what truck you have, year, mileage, model, engine type etc, it makes it easier to comment.
Go to your profile (by clicking on your name in the top right of the screen) and create a suitable signature, it shows on every post then, and helps a lot.
