I hate when I have an uphill battle on stupid simple things.
The Missing Linc:
I ordered the parking brake switch, it’ll be here in a few days
I replaced the brake lights switch on the brake pedal, but I’m still having intermittent illumination. There’s a little play in the pedal, I’m wondering if something is worn in the linkage. Nothing I ever felt was unsafe, the truck stops fine, but I’m thinking that little wiggle might defeat the spring loaded part of the switch. If anybody has any wisdom on this item, I would love to hear it. I’m thinking I’m going to start with bleeding the brakes.
The Road Ranger:
Fuel pressure checks out, new plugs, new wires, new fuel pump, new fuel filter, and some other things. It’s still breaks up under power or when you just rev it high with no load.
So I bought the cam position sensor. Not the whole thing that goes down in the engine, just the sensor cap. When I finally got it off, the old one looked pretty rough.
What an incredible design, huh? The diabolical Ford designer (the one who has the witche’s kettle in his office) who put the smallest screws possible on this unit that is in the most inaccessible part of the engine, well, he has become number three on my list. Number one is the guy who invented speed bumps. Number two is the marketing genius who figured out how to make a two pack for those little items that you need once every 10 years.. That one was well thought out, because of course you put the spare one away, but sometime between seven and eight years you lose it, so the next time you need it, you have to buy two more of them. And now there’s this malicious idiot who works in a dark cubicle who designed this thing with the smallest screws possible, and puts it in the hardest place to reach or you can find without removing the top of the engine. I think we should put all three of them in a dumpster that we get from behind a fish store and roll them down the hill on the seventh layer of hell for all time. But I digress…
I took the main wiring harness cable off the firewall and a couple little things and folded them over to the driver side tire. You can’t see the unit at all, so I used my ham hock hands to reach around upside down and backwards, and feel the thing out with my railroad tie fingers.
I started trying to unscrew the screws with a quarter inch ratchet with no extensions, and I could actually get it onto the screw, but there was no swing room in any direction because of all the big wiring harnesses, and whatever down there. I say whatever, cause you can’t see it unless you remove the body of the truck or something.
Then I drew on the sum of my mechanical knowledge and tools, and I came up with this:
View attachment 140082View attachment 140083
That’s a quarter inch ratchet with about 15 or 16 inches of quarter inch extensions. There’s the socket, then a universal, then a couple of wobble end extensions, and then a long extension to get it high enough in the air that you could twist the ratchet without hitting the back of the engine or the firewall. With all that I could get a little bit of an S carve so you could work it around the back of the upper intake manifold. I finally learned to put a little masking tape on such things to hold them together after losing about 10,000 sockets somewhere down inside the engine department.
I had to lay on my stomach on the fender, and reach my left hand all the way down and around, so with that trial and error torture, I could eventually slip the socket on the head of the bolt. While the ratchet was free in the air, I was in such an awkward position, that you could barely work it back-and-forth. But I only knocked it off the screw about 10 times. And no, I did not lose the skin from my knuckles, it’s all still down there behind the engine.
Of course, the best part of this kind of a story is when it all works out. Well screw that, it didn’t fix squat. The thing still breaks up when you read it high, and it breaks up under any kind of a load.
I’ll tackle the coil pack and the fuel rail relief valve today.
Correct me if I’m wrong, but if that doesn’t fix it, the only thing left are the injectors themselves, yes/no?
Is there any kind of a throttle positioning sensor that might cause the problem?
