Hi All,
New to the forum and somewhat "new" to FJ ownership (I will explain). I need help from the experts here to get my rig all square.
"New" FJ explanation: Long story short - I bought a FJ60 years ago from a guy who had several FJs. I didn't know anything about FJs or mechanics in general and unfortunately he completely screwed me over, intentionally. He hid the fact that the FJ had been rolled over, had tons of mechanical issues, etc. I lived in a garage apartment at the time with no space to work on it (or knowledge of how to do so) so I sold it (and ended up always regretting it). Years later, I found a low mileage, 3 owner western desert rig and bought it and had it shipped across the country. Haven't had much time with work or a new baby to work on the rig but am starting to tackle it.
So here's where I need help:
1. Engine runs rough, when it runs - I can see it's got new distributor and wires, looks like maybe the PO threw some parts at it. While driving one day it started to idle rough - revving high and low then a few days later when driving it died. It would start and idle but stall out as soon as I tried to give it gas and drive. I was cutting through a neighborhood coming home so was able to idle the rest of the way back. As I started digging into this - I found that the FRAM inline fuel filter on the supply line to the fuel pump was dry - zero fuel flowing through it. I put some fuel directly into the carb through the vent tubes and it started immediately and ran until that fuel burned off. This confirmed my suspicion that the fuel pump was bad. I put fuel directly into the carb again but this time the FRAM filter started to have a small amount of fuel run through it. I went ahead and changed the pump because I thought that in-line filter should be FULL of gas. With the new pump on, I have the same result and same trickle through the FRAM filter. This FRAM filter is in-line AFTER the factory in-line filter. I'm waiting for delivery on a new OEM filter. After I replace this, I will remove the FRAM (I am hoping the OEM may just be original or old enough that it's clogged and is what is restricting the fuel flow - this would be best-case since it's a simple fix).
1A - should I replace the fuel pump or not? Given I have no improvement in fuel flow - I am inclined to put the old pump back on (looks like it was already replaced) because another factor is that the hard lines coming off the top of the fuel pump are not exactly in the same spot as previous pump and one of the lines hits the oil filter now.
1B - Fuel pump spacer - I cannot tell if my engine has a spacer or not - the pump I pulled off has a rubber gasket and what looks like another (very thin) rubber gasket on the block - NOT a spacer. But if I DO have a spacer and it's now compressed over time - I read that this can position the pump too far into the block - would this affect fuel flow? I have spacer on order also in case I need this or this is what's causing my low fuel flow
2 - Exhaust Leak - I have a MAJOR exhaust leak under the hood - I assume it's just the manifold gasket. Anyone have a link for a tutorial on the easiest way to change this - I looked last night in the dark and the hardest part looks like taking everything off that's above/around the exhaust manifold.
Rig is a 1985, 148K original miles, 3 owners on OME lift. Would also appreciate suggestions on new tires that will fit OEM wheels.
Thanks in advance!
