1991 Porsche C2 Targa
 

Edit: Moved out of the 996 buyers guide to it's own post--PorscheDoc

I just recently purchased a 1991 Porsche Carrera 2 Targa. I have some warning lights that are on and have no idea what to do. The fuel gauge glass is also blurred. I will try to attach some pictures so I might be able to get some direction on this. Thanks

Well you have an airbag light on, a seatbelt light on, and the rear deck lid light is on. The rear deck lid light should go off after you reach about 5mph (if it is indeed closed). The seatbelt light should go off when you put on your seatbelt. If not, then the buckle is probably shorted out, which will also throw the airbag light. The exclamation point will come on when those other lights are on.

The fogged glass needs to be pulled and sent out for a new glass to be installed. Common problem. Contact North Hollywood Speedometer.

Awesome, I really appreciate it. Any suggestions where to get the seat belt buckle? The car has only 19K miles on it so I doubt it is the airbag. Here are more prictures:

Ideally you should get the code read down from the abs module so you aren't just guessing. You can pull the seat and make sure everything is plugged in, and if everything is good there, then try a new buckle (from dealer, ebay, etc).

I wonder why this car is so hard to start in the mornings. No snow on guam, it's a tropical island so i do not know. Any ideas?

fuel pressure could be leaking down, bad accumulator, bad check valve, etc.

Check the accumulator.

Fuel Accumulator? It takes 10 to 20 cranks for it to start. Any suggestions where to buy the seatbelt buckle? I need a place that would ship via USPS Priority Mail. It cost a lot of money to send things to Guam via another method.

I am also wondering if this is a CIS or EFI fuel system.

Somebody told me that this model does not have a fuel accumulator? I also need to buy the rubber or plastic gasket that goes in between the fender and body and also the one in between the rocker panel and the body.

Thanks,

Oops, brain fart, was thinking turbo. yea the NA does not have the accumulator and is EFI, so I would start with checking the fuel leakdown with a gauge after you shut the car off. This will tell you if you have a bad check valve or not. If it holds pressure for 20 minutes, then my next guess would be to start looking at the DME relay (you should have a spare on hand anyway), and reference sensor.

What do you mean by saying I should have a spare of the DME relay?

They tend to go bad now and again, and will leave you stranded. If you keep a spare one in the glovebox you can pop it in and go. It will cause a no start issue (car will crank, but will not fire up and run), worse when hot. They are about 25 bucks.

This happened to me the other day I turned off the car a few minutes later it would not start. I left it for about 2 hours and when I came back it started. It is crazy.

Thanks a lot for all the help.

Thanks guys worked on the Porsche this weekend. I have a couple of questions.

1. Where is the DME relay located (fuel pump relay)? Under the drivers seat?

2. Are the front fenders on the 1991 C2 removable? I need to get to the rust.

3. Is the windshield hard to remove?

4. The radio does not work it just displays 4 zeros. I have the code but when I try to input nothing happens.

Thanks,

Jay

1. Should be in your front fuse panel, passenger side rear part of the front trunk under the carpet.

2. Yes

3. Yes

4. Maybe the radio has been swapped and uses a different code? pull it out and get the serial number off the side and call your porsche dealer and they should be able to tell you the proper code.

How hard is it to get the fenders out? on a scale of 1 to 10. 10 being the most difficult.

Strange I have the original code and the radio is a Stuggart series Blaupunkt.

Thanks

Uh, maybe a 3-4. I can't judge your wrenching skills, and I have worked long on Porsche's professionally, so what might seem like a simple job to me probably seems like a mountain to others.

I agree I have never worked on Porsches but I have restored quite a few Morris/Austin Mini Cooper S'es from engine rebuilds to complete tear downs.

Doc, the car used to start but it was hard now the car does not even start at all. Is this also caused by a bad DME relay?

Thanks,

jay

Replaced the DME relay and the car runs and starts like the way it should. Awesome! Thanks Doc
