hey all. can somebody explain the install procedure and what tools are required?

 

Let me think...hmm..I think you will need 10mm socket, a 13mm socket, reg. screwdriver, and a torx driver, but I cant remember the size...I'm sure someone else will. 10 mm for the bolts on the intake, about 6 of 'em,(also remove the bolt holding the dipstick tube), loosen the black rubber hose coming from the intercooler,swivel the intake (with grid heater below) up around, and out of the way. There is a black box on top of the injection pump with 3 13mm bolts holding it down. Remove these. There is also a wire connection on the bottom of this black box, unplug it. (do not turn ignition on with this unplugged...bad things can happen.) Lift the black box out of the way, and viola! there is the orig. pump cover. About 6 torx bolts held mine in place. Remove this. Place new and improved cover on. In regards to the little allen screw that makes the actual contact inside the pump cover, CAREFULLY thread this in untill you feel slight resistance, then go 1/4 turn and stop. Attach the comp pump wire, (you DONT use the ground that came with the cover...thats for a different product) Plug the wires back into the black box, then turn the ignition key on, and check for 12 volts. If so, you're golden. If not, try CAREFULLY threading the allen screw a little more. Should'nt have any problems. Re-assemble . And HANG ON WOOHOOO!!! ;D I hope I have'nt missed anything, and if I have someone PLEASE chime in as I dont want to steer anyone in the wrong direction. Sorry it took me so long to explain a fairly simple procedure, but I was going through it in my head as I went along. BTW I have since traded my '01 ETH/DEE for a '03 ETH/DEE so...I have a comp and a pump cover for sale. If anyone's interested, just pm me, I'll get back with ya. (also have service manuals too) I bought the Comp here off this great site, and only used it 3 weeks before weakening and buying a '03.

 

Thanks! just trying to get a good feel for the nature of the install. sounds pretty simply. question--when you check for 12V, I assume that you put the voltmeter probe on the pump wire itself, and that:<br><br>1. this 12V source comes from the pump itself<br>2. the comp box does not source 12V on the pump wire<br>3. when you measure 12V on the pump wire, you are verifying the connection under the cover.<br><br>just trying to understand what you are measuring, and how things work. sounds like the connection is normally at 12V and that when the comp box fires, it must drive the wire down to ground potential. that is, 12V = do nothing and 0V = fire the fuel solenoid. <br><br>one question though. I'm puzzled by the fact that this cover thing works so well -- there must be some circuit board eyelet, or connection receptical inside the cover for this to work. Which raises the question regarding what Bosch had in mind (why did they manufacture it this way and why is this so easy?). <br><br>Also, where does the comp gnd wire go? I assume any convenient screw you can find in the vicinity?

 

Yes, you are checking for a good contact inside the pump cover when checking for 12 v. I grounded my comp on the same bolt that the grid heater was grounded to. Seemed to work fine. All I did was turn the keyswitch to &quot;on&quot; position, and checked for 12 volts on the allen screw in the pump cover. Just be carefull not to crack the circuit board with the allen screw.<br><br> Cat Cracker.
