Alright here is some back ground on the problem...
As I mentioned in an earlier post. My '85 244 started having some fuel problems. it started acting like it was starving for fuel a bit, mostly a slight loss of power. Last week I was driving over a mountain with a half tank of gas, and it started cutting out. I was afraid it was going to stall on me on this mountain road with no place to pull off, so I turned it around and headed back down the mountain. I thought I would top off the tank to see if that would help.
At the bottom of the mountain it stalled out completely on me. After cranking on it a while, I got it cranked back up, made it to the station, fueled up, and made it back over the mountain without a hitch. When I got back home I was back down to a 1/2 tank. The next morning I got up and drove it about 20 miles, and it didn't miss a lick. But when I went to crank it up it was missing so bad it wouldn't drive.
My first thought was the fuel filter. I pulled the fiter/high pressure pump assembly off and was able to blow through the filter. I poured 5 gallons of gas in it and brought it up to a little over 3/4's of a tank.
After putting it back together, I noticed that I had pretty good pressure at the regulator, as it would let go pretty good when I pulled the fuel line off. However, when disconnecting the regulator from the fuel rail and giving it a whirl, nothing. There was nothing passing through the fuel pressure regulator.
Well, I wasn't aware of a regulator doing that. I figured if anything it would be passing too much fuel pressure, not blocking all fuel. Nevertheless, I decided to go ahead and get a regulator, and since I am in Mexico and had to have the parts shipped up, I didn't want to take any chances. I also ordered an in-tank pump, a high pressure pump, and a fuel filter.
The parts came in, and I stuck the new regulator on there. Nothing. I dropped the assembly and put the new high pressure pump and filter on. Nothing.
I pulled the hose off the regulator, and it had substantially more pressure than it did before. I took a gasoline bath. I turned it over and gas was pumping through.
I put the fuel line back on the regulator and disconnected the regulator from the fuel rail. I turned it over, and again, nothing coming out of the fuel pressure regulator.
Can anyone give me any idea of what is going on? why isn't my fuel pressure regulator passing any fuel through it. How could the new one be bad? How could a brand new regulator be bad? How could it be bad in such a way that it would completely cut off the fuel flow?
Any input would be greatly appreciated.
