Huge boxster problem...
 
So the car recently just won't start it cranks but doesn't start and the top doesn't work it doesn't go up Or down the lights on so i cant get to the engine to fix it and I don't know how to fix this.

Click on the link the the below that says, "so your top is stuck in the closed position?"

No start:
The short answer is to ask here for a competent ,honest Indie in your area.
The diagnosis list is long and complex to act on. But let's try one simple thing- when the engine cranks, does the tachometer needle move slightly?

No it doesnt move at all

Sounds like it may be the crank position sensor.

CPS, Crank Position Sensor, not working!

That indicates the CPS is defective.

Timco had an issue a while back that looked like a CPS and it turned out to be the fuel pump. Although the rpm not moving sure sounds like CPS, not to be confused with a camshaft sensor.

What ohms did the sensor read when you did the test before replacing it? Is the new one reading different or could it be a faulty one out of the box?

Sounds like your muffler bearings need to be re-packed. I recommend using 30 weight grease. Let me know if you need a DIY.

Here is the definitive test from JFP:
"Remove the CPS sensor connector, connect your multimeter to pin #1 and pin#2, at 68F it should read 0.8-1.0K ohms; then connect the multimeter to pin #1 and pin #3 and it should read infinite ohms; if it does not read correctly in either range, can the sensor and replace it."

What does "at 68F" mean? Are you referring to temperature? I am standing by for ridicule, but I am also suffering from starting issues. Unfortunately I posted the CPS failure post before I saw this one.

I asked but still don't see the answer, what did you get for ohm values when you tested it? Replacing a part with a new part is usually a way to eliminate something but it can also get you into a whole world of problems when you assume the new part functions as it should without testing it because you will chase other problems when the real problem can still be that part.

Anker 03-06-2017 05:55 AM

68 degrees Fahrenheit!

Start a new thread. Glad to help. Back to basics. Does the tach move when you crank?

Check fuel rail pressure next.

Tach just sits there and does nothing, not even a quiver. However, the tach does the same thing when it starts.
New thread started under the heading CSP FAILURE???

Thanks for everyones help and im sorry for being rude if i was , but idk what im doing and im just gonna have to spend $1000+ to get it fixed

Timco 03-06-2017 02:42 PM

Not screwed yet by far. It's all good man.

CPS is pretty cheap. If you can't test it, I'd still start there. Not super easy to get to. If you want to do more testing first, verify fuel pressure is present.

These are not cars to own if you can't scrounge up $2k if needed unless you can do your own testing and wrenching to make it more affordable. You may have got a great deal, but to fix anything on it it's still a Porsche all the way around.

Jamesp 03-06-2017 03:03 PM

Apology accepted.

Things that make the car not start.

Fuel pump

You can pull the fuel pump relay and jumper it to run the pump. Search the forum for fuel pump and you'll run into it. If the pump runs scratch that off the list.

CPS - but usually fails hot and it seems you replaced it already.

Immobilizer under the drivers seat. Is it wet under the drivers seat? This is a whole new adventure if it is.

Top not working -I'm assuming the top motor is not running. Make sure the parking brake is on ( I made this mistake once). If the parking brake is pulled cycle it a couple of times to see if the top micro switch is failing.

Latch and unlatch the top a few times as well (another micro switch)

I don't understand what you mean by "the lights on so i cant get to the engine to fix it"

If it were me, I'd jumper the fuel pump next. Very common failure and easy test to run.

Ok so one day i was closing the top and it didnt go all the way to closing but i could snap it into the latch and the light stayed on, now when i try to open it sounds like it died and wont open , just to get to anything in this car is ridicoulus

I was wrong. :(

There's a micro switch in the latch receiver on the windshield that needs to show top closed and light will go off. Stick your finger in there and make it click and see if it broke.

My code reader say evaporation emission control and oxygen sensor woul any of these make it not start??

No, those would not stop the car from starting.

To better inform folks trying to help you, you should give the year of the car, S or Base, and manual transmission or Tiptronic.

Then a complete description of what is going on when you try to start the car. For example, when I turn the key the dash lights go on, but it does not turn over when I try to start it. Or, it turns over slowly, or turns over normally.

Let the forum know everything you did, and if you are asked to double check something you should, that means someone has screwed that up before and you might have.

Everything you tell the forum is a clue that will help the forum (and you) solve the problem. for instance, I have no idea if the car stopped running on the side of the road, if it acted up but ran then stopped, or if everything was fine and then is just would not start. Those details are very important.

Additionally - if you have not checked the fuel pump relay above the fuse box, that is a very common cause for not starting. Some folks carry a spare. Search the forum on how to check it, the information is here. Checking the fuel rail pressure as suggested below will clear both the fuel pump and the relay, or point to one or the other.

I'm fairly confident if you take some time searching / reading this forum you will be able to get it started.
