Man, I hope your pump didn't crap itself. Sounds all too similar to how mine acted. I think your truck is getting back at you for wanting to pull it apart.

[Tacoclaw]

That's better, but I don't need you Debbie-downering my thread all up.

I'm gonna sthi if that compressor housing shows up right as my pump takes a dump. I won't be that surprised, just...disappointed.

[AHineman]

Perfect time to get a benched pump, a little bigger injectors and keep the twins.

I thought you had that pump gone through a few years ago though. Maybe that new fuel system is sucking air or something.

[Tacoclaw]

Meh, I'm not in the money-spending mood right now. I don't care how many benches my pump sits on, as long as it functions. It was resealed, but I don;t know exactly what he did to it. I assumed it was out of fuel or sucking air, but the miss(s) are just too repetitive to be something that random.

Dammit, "I'd like to solve the puzzle" is a Wheel of Fortune thing, isn't it?

Yes, but I don't watch enough of it to get your rebuttal Jeopardy and Wheel of Fortune, what's the difference

[ellis93]

the miss(s) are just too repetitive to be something that random.

What exactly is it doing.

Ever since I've installed my injectors I'm getting some screwy running every now and again. Cold idle is normal,hot is fine but turn on the a/c and you get a slight shake. AC off and it'll go away.

A week or so ago I went after a track hoe and had to make the truck bow up a few times to get up a hill with the load,came to a stop sign,had it chuggalug there. Sound similar?

[Tacoclaw]

It idled as perfect as ever when I first started it. I've had a slight wandering idle for a while now, but I've always blamed it on the fact that I use my cable as the idle stop and not the actual screw. It never seemed to return to the exact same idle every day.

Anyways, now it just seems to be hitting on one or two cylinders. It's very rhythmic and not random at all, and when I pull my shutoff cable while I'm cranking the hits go away and it goes to a normal no-fuel crank. Put the cable back in and it goes right back to what it was. I took it on an hour long road trip this weekend and it never gave me a hiccup. Park it in the yard for a couple days and all of a sudden it's all attitude.

I'll crack the injector lines and see what they're spraying like when I get around to it.

[Tacoclaw]

Well, it seems the old girl was just being bitchy. I cracked all 6 lines and cranked it over about 30 times. Got a usual jet out of 6, a medium jet out of 4, dribbles out of 1, 3, and 5, and a bone-dry #2.

I knew what that meant, so I tightened them all up and went to put my injector wrench back in the glovebox. I figured I'd just crank on it for a while longer, just so it knew how disappointed I was. After 3 rolls it started running on what sounded like 3 cylinders, so I held it at around 1/2 throttle and she cleared right up.

Huh.

I guess next year I won't forget our injector bleeding anniversary.

[AHineman]

Odd, it had to loose prime somehow. Oh well, glad she's back running.

[ellis93]

It knows what's coming

[Tacoclaw]

After being with me this long I would assume it knows that the stunt it just pulled would get it torn apart even faster. Shit, that makes me want to gut it even though the RC is nowhere near ready yet.

Oh well, maybe I'll take it to town and grab some food. You know, just dare it to leave me sitting somewhere besides my own driveway.

[Hansen01]

Sounds all to much like my truck, just does what it wants for a while

[ahale2772]

mine does that as well, after a while of sitting it seems to loose prime, starts, runs a bit rough, set the high idle and it clears up after about a minute.

allways ran 100% fine untill I put a rebuilt set of stock sticks in that have never seemd to run right

[Tacoclaw]

I still wasn't sure if the pump was alright or not, so I decided to put it to the test. Drove around all night last night and then went to work and picked up a couple tons of #4 gravel. This was exactly 2 tons, it grossed at 9640. Kinda sad that that's not that far from the factory weight on some Ford trucks I've been around recently.



I swear those springs are some kind of practical joke spring. There's no way it can ride as rough as it does and still squat like that the second it gets some weight on it.

[oldestof11]

Shorter spring lengths do that it seems.
