Drivetrain swap! 97 - 99

[SunlitComet]

orings snap in a grove the injector body holes. Then fuel lines. Then that little plate with bent ends facing up. That pushes down on the lines ridges then washers and lockouts.

That doesn't show the o-rings, washers and bushings that are inside that plunum dictated as number 19.

I'll figure it out I guess.

Big day today!

Buttoning up odds and ends, hopefully she'll be running tonight!

Exhaust, fuel lines, oil lines.

 

[Shiftx450]

Which ecm should I use?

Any difference?

 

[SunlitComet]

the 99. there is a huge difference save yourself the head ache and use the 99 and it sorta does show it but it is an exploded view that includes the lines but now that you mention the plenum. you go fuel body bracket to lower intake, bracket will be loose, fuel body to bracket, then oval oring around the body above the horizontal lip that sticks out, lube with oil of some sort really well maybe even vasoline. then plenum down then the stuff i mentioned above for which i corrected the first word. once you put the plenum down you will notice you will be fighting against the big oval oring. press around the out side of it to get the plenum seated properly. afterwards you will need to carefully try to pull that body up a bit otherwise the wired connector will not sit and lock properly. hope that clarified it.

btw if you dont have the newly redesigned injector system now would probably be the best time to do it while it is still apart. http://www.amazon.com/Delphi-FJ10566-Fuel-Injector/dp/B000TYLIFS summit may have it cheaper at the moment. i personally refer this as a required part if not already installed. You must be one with the Vortec like me. and when you get this thing started there are some procedures that need to be done which are CAM_RETARD setting verification and a Case Relearn procedure for the crankshaft sensor since it is a different one. then was there before. will need a scanner with the right software to do them.

or maybe this what you wanted. parts are no longer identified as it typically does not come apart like you see in pic. http://www.genmotorinfo.com/Picture.../5.0M,L31/5.7R)+-+TX03-013&pid=951025TX03-013

Came in to grab a bite to eat, thanks for that last diagram - it helped, got some new o rings and got em in.

I should've payed closer attention when the oil pressure switch was mentioned.

They're different, found out the hard way. But it's good now.

---------- Post added at 09:40 PM ---------- Previous post was at 08:20 PM ----------

I remember taking this off, but cannot remember where it connects:

It comes from this Evap canister looking thingy

Also can't remember where this little vacuum hose comes from that's supposed to connect to this, same with the electrical connector. Can't find it.

 

[SunlitComet]

the evap hose should connect to the vapor canister purge solenoid. should be just forward of the ignition coil and icu bracket. just in front of that where your left thumb is should be a piece of open l shaped tubing. just point it down. it is a vent line.

 

[Shiftx450]

Still don't see it. Get these three things lined up, vacuum hose, vacuum port, and electrical port.

No clue how to place them.

Any more of them useful diagrams floating around?

Also, the other end of that little canister with the open port and unknown electrical connector

Power steering pump pulley installation has me scratching my head as well.

Supposedly there should be threads in the center of the shaft? Mine is just a hex, and I can't get anything from the puller kit to bite.

---------- Post added at 11:25 PM ---------- Previous post was at 11:24 PM ----------

Done for the night.

 

[SunlitComet]

Pump shaft has threaded hole. And very important pump shaft must be flush to 2mm to pulley hub grace. Looking up otherr stuff for you.

Point out the little csnister with plug in question. I may have missed something. Bandwith is not very strong here thru phone hotspot or I just may not have understood you.

 

[Shiftx450]

Awesome, THANK YOU.

Now what about the other breather and electrical stuff?
Here's the pic:

[SunlitComet]

will look again and when laundry is done will go snap a pic or two of my own for you to point out. i have 96 but identical except for vapor canister and oil pressure switch. no worries.

 

[Shiftx450]

I just took it off, doesn't appear to be present or necessary on the 97.

Had to swap that solenoid, they were slightly different where the vacuum hose connects, thats why I was struggling.

Need oil lines.

Can you provide GM part numbers for the following:

Oil cooler lines identified in them drawings as 12, 13, fittings 8, 9, 15

Trans cooler lines 12, 13, 16, fittings 6, 7, 8, 10, 14, 19, 20

 

[SunlitComet]

if you would not mine just to make sure now that application is more specific pick your parts using theses diagrams instead now.

i will likely get to them tomorrow and not tonight.

 

[Shiftx450]

This most recent trans diagram is inaccurate (for my application) for 2 reasons.

-my oil lines come into the trans on a slight angle
-I am attempting to use the external trans cooler as well, as depicted in the first diagram you provided a few days ago

 

[SunlitComet]

Okay I will use that on then for the granny. How about the engine oil cooler pic?

 

[Shiftx450]

Engine cooler pic is good.

Called the dealer and ordered the trans lines, gotta go pick them up in the morning. Oil lines - napa had them in stock. Got em on the truck.

Trans cooler lines - dealer told me they dont make the line that goes from the lower radiator port to the trans, said I had to make it myself. I'm going to wire wheel the one I have and shoot some rust inhibitive paint on it to prolong it's life and reuse it. Got all new fittings and clips coming.

Just repaired a broken power steering wire, new fuel filter, got all my fluids and stuff today. Oil filter in. Buttoning up some of the smaller things.

Heading back out now to pull the grill off and to mount the Aux Oil Cooler and get the radiator in. Gonna get the oil lines hooked up and fluid in. Get the rad hoses and heater hoses in, Dexcool in. Fan shrouds, fan. All going to go in hopefully tonight. I'll get some pics up when I'm done for the night.

Hopefully she'll start tomorrow!

I heard you mention needing a tune.. ? Please explain.

---------- Post added at 05:50 PM ---------- Previous post was at 05:50 PM ----------

I thought the computer will reset itself after power has been disconnected for awhile.

All the leftovers are for sale! First reasonable offer gets it. http://southjersey.craigslist.org/cto/3529655924.html

 

[SunlitComet]

no tune needed but wouldnt not hurt either. you need to verify that the alignment between crank and cam sensor is correct. also need to perform a case relearn procedure because the crankshaft sensor is not the original one. and once running performance may suffer a tiny bit while pcm goes thru its learning phase but should be normal in a few miles or so.

 

[Shiftx450]

Please elaborate in this 'case relearn procedure'

 

[SunlitComet]

Crankshaft Position (CKP) - Variation Learn Procedure CRANKSHAFT POSITION (CKP) SYSTEM VARIATION LEARN PROCEDURE

1. Install the scan tool.
2. Apply the vehicle's parking brake.
3. Block the drive wheels.
4. Close the hood.
5. Place the vehicle's transmission in Park (AT) or Neutral (MT).
6. Idle the engine until the coolant temperature reaches 65°C (150°F).
7. Turn OFF all the accessories.

IMPORTANT: If the Crankshaft Position (CKP) System Variation Learn Procedure cannot be completed successfully, refer to DTC P1336 CKP System Variation Not Learned for additional diagnostic information.

1. Enable the Crankshaft Position System Variation Learn Procedure with the scan tool.

IMPORTANT: After the ignition switch is turned to the CRANK position, the Vehicle Control Module (VCM) must see a change in the state of brake switch (Released to Applied) to run the learn procedure. Also, the service brakes and the parking brake must be held throughout the duration of the learn procedure.

1. Apply and hold the service brakes.

IMPORTANT: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is returned to the operator and the engine will respond to throttle position after the learn procedure is complete.

1. Slowly raise the engine speed to 4,000 RPM.
2. Immediately release the throttle when the engine speed decreases.
3. Turn OFF the ignition for 15 seconds after the learn procedure is completed successfully.

K. Everything hooked up as it should be (I hope), all fluids in, just tried to hit it.

Tried to cycle the fuel pump, it's not cycling until the key is turned off?

Usual cycles when the key is turned to the on position.

Why would it be backwards?

Also something wrong with the starter.. Dad did that part, lets see what's wrong. Gonna detach, inspect, and reset.

Acts like its not lined up or something, it spins but grinds and doesn't engage properly to turn motor over.

---------- Post added at 01:56 PM ---------- Previous post was at 01:22 PM ----------

Think the starters are slightly different.

Going to swap them and see what happens.

Any input on the fuel pump concern?

 

[SunlitComet]

pcm powers fuel pump relay and when switch is moved to on pump should prime for two seconds. exactly what positions does it tun on and off if applicable.
