They don't exist. Some have posted up on the 924 board (924board.org) with some degree of success... others, myself included, have failed to rebuild them successfully.

Mainly it seems to be a matter of finding gas-resistant replacement o-rings, and getting it to seal back up properly without leaking.

Wheeler Dealers.... my PO had the same bright idea. He lost his shirt doing that!!! He had $7000 invested in the car and when I bought it, it still needed AC, brakes, suspension, timing belt, wapter pump, front crank seal, power steering lines, new fuel injectors and host of other things. He lost 4 grand on that bright idea.

These cars are not good cars to try to flip.

Have you had any luck getting it to run yet?

Yeah it was a bright idea, I think.. unlike your friend I just have a few hundred in it... anyway, it still wont start and I dont feel like making a new account at 924board.org so maybe some video might help someone explain it?

It's getting fuel, its getting spark (sounds like), I checked the vacuum lines that I can see... someone looped one of the vacuum lines and pluggged one of the holes in the throttle body so I dont know what goes there...

Part 1 - Porsche 924 wont run - YouTube
Part 2 - CIMG0317 - YouTube


In the video, Im pressing the gas as soon as it fires and I can actually rev it a bit but then it dies... does this sound like a vacuum leak? Thanks!

Are you sure that isn't your ignition switch? Does the car only run/rev while in the "start" position and then dies when you release the key?

These switches are notorious for failing and causing that type of problem.

On another note, if your Control pressure is the same as your Fuel pressure, your WUR is bad. Take the intake manifold off and remove the WUR and clean it out.

Good luck,
Keith

I have no way of measuring fuel pressure but I already disassembled and cleaned the WUR... in the process of hotwiring the car now.

http://www.924.org/techsection/12body.htm#2%20-%20Ignition%20Lock%20Removal/Replacement
924.org says - "The pin numbers are marked on the connector; jump 30 (battery) to 15 (ignition on) to turn on the ignition, and touch 30 to 50 (starter) to trigger the starter."

I cant figure out which wires in the ignition connector are 30, 15 and 50 because theyre NOT marked on the connector like the instructions say.... or maybe they're talking about the colors and stripes as markings? in which case I dont know what means what.....

CIS relies on fuel pressure for 100% of its function. You will never get the car running correctly without a proper tester.

So the car runs fine while the starter is engaged, looks like. Your ignition lights remain on (Oil/Alt) even while the car dies, so it seems like the ignition switch is probably OK. What usually happens there is that the when the key returns to the ON position the ignition cuts out (You lose those lights).

This to me sounds like more of a fuel pump relay issue. You need to get a Haynes manual and look at how the circuitry is wired for the fuel pump etc. off that relay. Power to the coil is also supplied directly off the battery while the starter is engaged, which goes away when the starter is released.

Not sure what work has been done on your car, so those are some obvious places to start. Check power to your coil, replace the relay.

Good luck, Keith

just kidding, it was the coil... the car will stay running if the coil is hooked directly to the battery

mice have been chewing on the wires, i had the same problem with the cold start injector

just needs a good tune up now... thanks for all the help
