New to the 4BT conversion world.
Just purchased a "90 GMC Sub 2500 4X4 with a "NEW" 4BT , and a (Redline rebuilt) auto(not sure which model) out of a 1 Ton dodge, thinking probably a 46RH since it has a shift lever coming up through the floor, coupled to a NP 205 professionally built by some performance place out in Cali, and has 4.10 gears with 285/65/18 tires.
Looks as though the engine label is missing (thinking it"s not really "NEW", but new reman), and not sure yet what fuel pump, or turbo it has. I'm hoping that maybe some can ID them by the attached Pic's
I purchased this as a non running vehicle, as the owner couldn't keep the batteries from going dead overnight.
In my complete optimism, I'm flying out to pick it up this coming weekend, and planning on driving it halfway across the country to get it home. Wish me luck......, I figure it was running when it was parked, so how hard can it be.(10-12 volts to the fuel solenoid, and fuel, and it should run, right?)
It looks to have a Larry B's fuel solenoid in it, and am thinking that it might be wired incorrectly(possibly not killing both hot leads), as they use the original GM ignition to start it, and push a button to shut it off. (anyone with any helpful hints in diagnosing?) I'm fairly mechanical, but pretty short in the electrical department.
The person that I'm buying it from told me that he had been driving it for a couple weeks no problem, went to get in it one day, and had just clicking. Replaced both batteries with 2 new Die Hard batteries, it fired right up and everything was good, until the next morning when he went out and it would not start. no clicking or anything.
He also tells me that he then being discouraged, and over his mechanical ability just decide to park it. he went out the other day after I committed to purchasing it, opened the door and the dome light came on, and he tried to start it. Apparently it acted like it wanted to turn over, but would not start.( it's been sitting now for a year since he last tried to start it).
Many thanks in advance for any helpful suggestions, I do appreciate it.
I plan on trying to make it a reliable rig with adequate power, and exceptional fuel mileage. The second item of business after I get it to run, is to install some kind of air cleaner before driving it any distance.
I am just short of overwhelmed by the amount of info on this site, so any pointers would be appreciated.
I'm thinking a intercooler(anyone have an idea of what intercooler would fit?),and maybe fuel spring and timing adjustment would be in order for starters, just unsure at this point what fuel pump and turbo are in it.(maybe someone can identify by the pics?)
