2000 Boxster Base- Manual 8/10 body Non runner - “Engine just stopped” So, a few weeks ago, I decided I needed another $700 project. Owner had no idea why it stopped running. Sat for several years. When I got it home and after completely detailing it, I decided to check and see what was in the oil sump. Nothing, but some very fine plastic bits. Nothing big and nothing metallic. Nothing suspicious in the oil filter. There is hope!!!! Next stop, check the timing. Here is what I found on bank 1..... It does appear that the engine jumped timing. I checked that “three letter” thing that everyone is paranoid about. All looked great! I next pulled the scavenger pump cover off, to take a look at the chain/sprocket. Ah.....this could be a clue.... i think I found out why the timing is off. My guess is that someone was in there before to replace the chain rails and guides, but neglected to do a thorough check and left some bits in there. A piece got caught in the sprockets. This is is the result of that little bit of plastic: Here is is what the valves looked like: Now I gotta figure out what I’m going to do next. For those that have experience with this kind of stuff, what advice would ya give?
A few things to help you figure out your problem. Make sure your gears in the spoiler mechanism are good. They are known to wear and not allow the spoiler to retract properly. Also, check the relays in the trunk for proper operation. Physically pull them out and test with a battery and voltmeter. You should hear a click. Read the wiring diagram to determine how to jump the pins on the motor, to make the spoiler go up and down. Not real difficult, and will confirm that mechanically all is good. Next, check the switch on the kickpanel. Same as the relay. Make sure it is working properly. Last, realize it is the dash cluster that controls the spoiler extending and retracting at speed. I’ve had to replace a bad cluster before, that prevented the spoiler from operating properly at speed and the dash light was on. Good luck. Oh...you’ll be taking the trunk apart.....sorry.
His videos are like potato chips......ya can’t watch just one!!!! Thoroughly enjoy all his videos, because he does a top notch job and always willing to share his information.
This is indeed a common problem, and an easy one to troubleshoot. Not overly expensive.
I agree about the cluster, although I have an extra one I can put in there. That is why I was trying to figure out whether the switch by the fuses is switching the ground or the power. From what the schematic looks like, it must be switching the ground. If that is the case, then the instrument cluster must be sending out voltage to activate the control side of the relays. I have pretty much everything figured out from there. Anybody's input would help.
Hi Loren, thanks for responding. I figured out how to apply current to the motor leads to retract and extend, by swapping power/ground on the Yellow/Green and Blue/Green wires. Motor works fine. Also tested the relays and the switch by the fuse panel, all good. I can trace power from the fuse on D7 to the relays and to the spoiler motor. I see the switch is wired through the instrument cluster. is the switch and instrument panel switching the ground? I think it might be a bad insturment cluster.
Spoiler doesn’t extend at speed, nor does it work with the switch. The spoiler light comes on in the dash at speed. Swapped in another spoiler mechanism, thinking it might be a bad mechanism, and no luck there. All fuses and relays have been replaced. HOWEVER, with the manual switch (by fuse box) unplugged, and I connect the rear wiring harness to the spoiler unit, I can hear the relay clock, and it will raise the spoiler about 1/2” and stop. If I unplug and plug back in, it will go up another 1/2”. I kept doing this (duh!!!) Now I have a fully extended spoiler, with no way to retract. I have the wiring diagram from Bentley manual. Any troublemshooting advice? What wires should I apply 12v power to, to retract? Any and all advice is helpful. Also, I tried to make heads or tails of the wiring diagram. I’m more mechanical oriented than automotive electronics. I just got a headache!!
TNT79Bronco replied to johnmh's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Thanks for letting us know how it turned out! Did you figure it out, or the desler？？
TNT79Bronco replied to Lyman Peterson's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Just a thought. Check the Parking break and see if that allows it to continue. I am trying to think of things that would cause it to stop, while in operation. Fob has nothing to do with it, IMHO....
I need some help reconnecting the vacuum hoses on my '03. Had to remove tiptronic to repair it, and either have a broken vacuum hose, and/or am as lost as I can be. I can't figure it out. Here is the vacuum diagram from the trunk. Part of the problem is, that I can't identify all the parts. The "white" connector goes into the intake. Off of that is a "Y". The "Yellow" line (vacuum hose) goes nowhere that I can tell. I am sure it connects somewhere, I just can't tell where. It is long. The "Pink" end of the "Y" is open. I am sure something sticks in there, just not too sure what. The "Green" line (vacuum hose) connects to what I believe is the Resonance Flap Valve. However, it is either broken (and connects with the "Blue" line (vacuum hose)), or inserts into the "Pink" end of the "Y". Not too sure which. The other end of the "Blue" line (vacuum hose) connects to a 4 way "Cross fitting", that connects to the vacuum reservoir. Shown as connection #1 below. I guess the upper end of the "Blue line" (vacuum hose) could connect to the "Pink" arm of the "Y". Again, not too sure. It is entirely possible, that the "Blue" and "Green" line is a broken line. If this is the case, not too sure what would plug into the "Pink" on the "Y". #2 "White" line (vacuum line) attaches to a switch, that I believe is associated with the tiptronic transmission. The lower end of the hose connects to the "Cross" fitting that is by the vacuum reservoir. The "Purple" line (vacuum line) is attached to a valve that controls coolant that goes to the tiptronic. #3 Line disappears somewhere deep into the engine somewhere. Can anyone help? Thanks!
I think I found my issue....... When I reinstalled the valve body, I neglected to make sure the selector tab was inserted into the piston. I hate removing things and reinstalling because I was stupid!
Had to remove the tiptronic to replace the trans oil pump and torque converter. Naturally, this involved removing a lot of the guts of the transmission. All seemed to go back into place with ease. The transmission is back in the car and electronic connectors back in place. However, when I tried to put the cable back on the shift knob ON THE TRANSMISSION, with the gear selector in PARK, the end of the cable was off, because the transmission shift selector would not move into the PARK position. The furthest back it would go is REVERSE. The position of the transmission was verified by the indicator on the dash readout. In Reverse, the two ends lines up perfectly and they did in neutral. If I connect the cable to the transmission mounting point, the gear selector will not go into park, because the shifting mechanism on the transmission is preventing it. I did did not remove the shifting mechanism on the transmission, nor did I mess with the shift cable or gear shift in the car. What would prevent the gear shifting mechanism (on the transmission) from being manually into the park position?
