CDFP Help

[DarkPasseng3r]

Removing the pump and installing the internals was no issue. My issues it trying to get the pump back into place.

Whatever the piece in my attachment is called, it is not low enough for me to get the pump back into place so I can screw it back in. Has anyone encountered this issue and if so, how was it resolved?

Compared to the picture from this install walkthough, mine is way too high for any progress to occur.

You might have to bump the motor(to rotate the cam lobe) make sure the f.p. relay is pulled!

So far, the way I understand that is make sure fp relay is pulled. Put key in ignition at attempt to start the vehicle. Correct me if I'm wrong; I need it explained a bit more.

[SLOWHATCH]

Thats all there is to it. Pull fp relay. You can also disconnect main harness to coils and bump start the car.

[kritz]

That's it, screw in each of the screws a little bit a time till the pump is seated and make sure the o-ring seal doesn't get pinched while it is going in. Let us know how you make out!

[atvfreek]

Yes just turn the key to the start position quickly and let off, this should move the crank a quarter turn or so.

[DarkPasseng3r]

Ok guys. Thanks. I bumped the starter earlier today but I guess not long enough to get anything to move. The only thing that happened was gasoline spillage. I'll try this again tomorrow and let yall know how it goes.

[kritz]

Well like I said keep us posted. But at least you don't have to deal with the cold like us up north, keep at it!

[DarkPasseng3r]

@kritz alright just went outside and hooked up battery and pulled the FP relay. Set up a gas catching container too for the open lines. I bumped the starter, nothing moved. Bumped it a few more times and still nothing.

Am I missing something? Am I supposed to be in gear?
Other thoughts that came to mind is to put car in first gear, find friction point on my clutch, and push the car a bit.

Bare in mind (although I'm on a gen2 ms3 forum), I am working on an MS6. I wouldn't think that there is a difference though.

why haven't you consulted nator houston??

I have, but everyone lives a bit far from me. I originally got the suggestion to bump the starter from them. But I gave up the first time because it didn't move what I wanted, and at the time, I didn't have a way to contain to fuel spill. But if it's the only solution, then I'll keep trying.

You could put the car in gear and push it until the cam lobe is in the correct position

I had mentioned this earlier, but can you explain this a bit further for this noob?

Do I just put it in gear and push, or do I have to hold the clutch at friction point and have someone else push?

Basically, I'm on my own, and until I get a hand, I'm trying to figure out ways to do this that doesn't require another person.

[kritz]

Sorry DP3 I hit the rack last night couldn't keep my eyes open.
heading to work now will check in when I get there,did you get
pump back together correctly and when you removed it did it spring
out ?

[DarkPasseng3r]

I feel confident I put the pump back in together correctly. When the pump was first removed, the spring and piston did come out after a little tug. Should the rebuilt fuel pump do the same?

you dont need to do anything with the cluch, with the motor off put the car in gear, release the parking brake and let the car roll foward or back a few feet, stop, put on the parking brake and check to see if the cam lobe is positioned correctly. Repeat if necessary.

When i reinstalled my upgraded pump, i thought the cam lobe was too high because the pump would not go in. I also had to give the pump a little tug to get it out. It turned out that the metal fuel line was just a hair too high and was blocking the pump at the bottom nipple to keep it from going in. So i gave the metal line a couple of love taps to move it down a hair.

I thought this too when it was first suggested to me, but I made sure it was way out of the way before trying to reinstall the pump.

I tried putting the car in gear and pushing but the car won't budge. So if you guys suggested that as a joke to make me look like an idiot But seriously though, I can't get the car to move. MS6s are heavy!

I'm open to all other suggestions.

[kritz]

Try 2nd or 3rd gear. Make sure that you have some oil on the o-ring and that it is not getting pinched. I'm posting in your local Nator for you!

WTF????? Manual cars don't move while turned off and in gear. Unless your shits fucked up. Hope you where not being serious.

Guess again, they will, you just have to push hard enough to overcome the compression and friction in the motor.

Hmmm. Or you can just hook it up to another car and tow it while in gear huh?

@DarkPasseng3r

Not trying to be a smart ass or anything but You do realize you have to compress the spring when you put the pump in correct? To an extent at least. But the screws should be long enough to at least catch, then screw them in evenly. Definitely make sure you oil that outer O ring so it doesn't get pinched like Kritz already mentioned.

[kritz]

Send me a round trip flight and I'll put it in for ya! Kidding aside how far does the pump body slide in before you feel spring tension?

Yes, I worked on this all day yesterday and my lats and shoulders are definitely feeling it. I had to push the FP in and hold it, as I try to let the screws catch thread. Since I have to compress pretty hard, my concern was that the tip of the piston would move around and scratch where it makes contact. I thought maybe there is another way because maybe the Cam lobe was just too high and not where it's supposed to be for a proper FP reinstall. Compared to the pic in the link in my OP, mine is way too high.

Have any of you installed the FP with that part as high as it is?

Quoting myself. (in the case you missed it).

Hold the gas and clutch pedal to the floor. Holding the gas pedal to the floor will keep the injectors from firing.

Turn the motor over briefly.

[SLOWHATCH]

I never looked at the how mine was sitting honestly. It went in pretty easy each time I've removed and re installed a pump.

[DarkPasseng3r]

@kritz, I have to compress the pump maybe a half a inch down just so the tip of the screws will reach the tread, then I have to push even further to try to get the screw to catch.

@rfinkle2 ...just tried it. Gonna try it one more time. I'm spilling fuel like crazy!

[kritz]

Can you catch a thread?

You'll get it. We have faith!

[DarkPasseng3r]

Alright guys, pulled the FP relay, even pulled harness for the coil pack, pushed in clutch and gas, turned the key to start (1 second at a time).... NOTHING! I dunno what the F is up!

@kritz, when I try to screw it in, I can get two screws to catch at a time. By the time I get to the third and have to reposition the pump to get the correct angle, one or both of the other screws pop out. I don't want to ruin the threads.

[rfinkle2]

Silly q, but your battery is still connected, correct?

[DarkPasseng3r]

Yes hahaha.

Houston Nator Forces have been activated

I've not done the HPFP but I'm certain someone else in town has. I've posted to the Nator Houston Facebook account which instantly sends the Bat-signal to all Nator Forces in the Houston area. I'm certain someone can help you out.

BTW, what part of town are you in?

[DarkPasseng3r]

Any one know what the socket size for the crank pulley is? May have to try that if I can find a ratchet long enough.

*Update* I actually can't even get to it so NVM that idea for now.

@chimmike would know.

[atvfreek]

Can you pull that follower/bucket out by hand? That might be wedged slighly, therefore you are not seeing the cam move.

[Chimmike]

crank pulley socket is like 32mm, IIRC.
