Anyone got the part number for the vacuum hose coming off the FPR? I think I finally narrowed down the starting issue I've been chasing to a crack in the elbow of the vacuum hose that's connected to the fuel pump regulator. Of course with my luck, as I pulled off the vacuum hose it snapped at the elbow. Anyone got the diagram too?

I got it, didn't realize the elbow joints were removable, just grabbed some generic ones from the store. 

 

Next question though, what the hell is this sound: https://youtu.be/Q8NRTJY9ZKc

Is there a more thorough write up on it? What does taking the snout off entail?

take the bolts out then pry the snout off via that indent. might have to take the alt off, but i was able to leave mine in, i have a 98. 

 

you need two bottles of sc fluid, dealer has it, or ebay. couplers are on ebay or zzp, you dont want a dorman or another factory one. the green ones seem to last longer. 

 

open the fill hole on the snout, suck out the old fluid with a old spray bottle or large syringe, the old oil stinks like hell, have latex gloves handy and two cans of brake cleaner. after you suck out the old fluid theres will still be some left in that will leak all over, so i stuffed a rag over the timing cover and laid one flat under the snout to catch what leaks out. wipe that crap down, then spray it down with brake cleaner. 

 

clean the inside of the snout and the gears on the sc.  

 

replace coupler and use anabolic sealer  on the snout ( thin smear) then bolt it back up and fill the snout with new oil.

You guys rule, thanks.

I'm gonna keep hijacking my own thread with an electrical issue, possibly a dumb problem.

I changed the vacuum hose elbows coming off the FPR and then it seemed to start just fine. While I was at the junk yard I picked up a power window/mirror switch because the driver window didn't work, and put it on my car, but the new switch made no difference. Started the car, but it really dragged. Turned it off and tried starting it again but then it wouldn't start.

I thought there may be a short so I tested the battery, 12.5volts. Disconnected the negative terminal and tested for a negative draw, but it didn't show anything, unless I was doing something wrong.

Took the battery out and gonna have it tested tomorrow.

Pulled the snout and changed the coupler with the green one from ZZP, changed the SC oil too. Is there still a rattle or is that sound normal? Am I over thinking it?

Also changed 2 drive belts, replaced vacuum lines and swapped the fuel pressure sensor. I'm still chasing the starting issue where I have to pump the gas while turning the key. Any suggestions?

you might have bad bearings in the blower making that sound still.  be easier to just find a used gen 3 blower and swap it on there. 

 

you have a way to scan the car? torque app or something?  if you see the long term fuel trims pegged at +16 you got a large vac leak. 

 

a clogged car could also make starting a bit hard. as well as needing a tune up bad. 

 

or a bad fpr could cause a hard start when cold. pull the vac line off it and see if it smells of gas. if it smells of gas, replace it.

By clogged car do you mean clogged fuel lines? Had them redone as an attempt to fix the issue. Only thing I haven't done is swapped the fuel pump.

FPR was my next thing to throw money at. How involved is that? Do I have to drain fuel?

FPR is easy.  Relieve the pressure from the fuel rail by way of the Schrader valve.  I usually stuff a rag over the valve and depress the valve core until the pressure is gone.  Others will pull the fuel pump fuse and start the car until it runs out of gas.  Then you can simply remove the clip and the FPR.  Remember that rags soaked in gas or oil can self-ignite if you just throw them in the trash.  Observe all other precautions when working around gas and fumes.

 

I think the other question was an auto-correct failure.  Most likely referring to clogged catalytic  converter (cat).

damn typo. cat not car lol  

 

dont replace the fpr unless it smells of gas. you can also run the engine vac line off and watch the nipple to spit gas out it.

I'll try that out and hold off on replacing it. The vac line elbow is new, the last 2 I put on were ripped up after a few months. Does that indicate anything?

Can you elaborate on that? I always see those plastic Ts at the store but I don't get how they can replace the runner elbows

the small white t's they sell, put a inch long length of vac line on one end for the snout or the fpr. and you made a new T.
