Hey guys, first of all thanks for all of your help in diagnosing and suggesting and in many cases being spot-on! I'm writing in this thread because what seems to have baffled me for a good number of weeks is finally getting to the point where I have no idea what else it could be. To be concise, I'll lay out what I've tried thus far, and what else can be done:
Truck is a 1981 FJ60, PO had it desmogged, and it has a trollhole carb on it (one wire, 12v direct to the FCS wiring harness). Problem is same as what is described above in this thread, and through troubleshooting with what has been suggested, I have managed to get it to mostly idle, but will only do it very reluctantly if without the choke. I'll drive it out, and as soon as we get out on the road, I'll go for maybe a half mile, and it will drop all power and stall- enough time to get it up to 4th gear.
I have tried the green wire 12v direct from battery to FCS wire, checked the fuse on the 10A engine fuse in the dash, pulled it out and started it with the 12v to FCS, the vacuum hose from distributor was incorrectly on the outer nipple (high altitude one) which I moved down closer to the distributor, which is where I'm pretty sure it's supposed to be, grounded the igniter with a separate strap that goes directly to the body as a ground, changed the fuel filter, looked in the glass in the carb to make sure that there is gas in the carb bowl. Lastly, yes- I have taken the gas cap off and tried that, all to no avail...
About the only other thing I can think of is that the fuel pump has gone bad, but from the looks of it, it looks itself almost brand new. I plan to change that on Friday or Saturday- whenever the parts get here.
Is there anything else I am just blatantly missing here?
One thing that comes to mind is this carb doesn't have a ground wire- only one wire coming off the FCS. Any thoughts on that, because I feel like I've literally tried everything...
Thanks in advance guys
