I have replaced DME relay 3 times. Replaced distributor. Mechanic says the only other thing he can think of causing starting issues is the fly wheel sensors. Any other suggestions?

Does the car crank??

Yes I just came on to delete the post. I took it to the Porsche dealer since my regular mechanic was busy. It turned out to be the after market alarm. Whoever installed in spliced into wire to the starter or something. It was removed and some re wiring had to be done. 509.00 to fix.

Just went out to go to store. The car is completely dead. Something must have killed the battery. I can't win.

Man don't even stress it you didn't have it bad I went to get an alarm system put in with sensors everything and guess what happened 3 months latter all my exterior lights didn't work only my headlight went to the dealer to have it checked they pulled the fuse box out and told me the alarm fried my fuse box and also messed up a shyt load of relays so $5,372 latter new fuse box relays wiring harnesses and had to throw away a $600 dollar alarm system never again will I step foot into a car audio store

Here's the trick if the car cranks but doesn't start take off the plugs to the spark plugs take each spark plug off grab your compressor put it at 40psi with a blow gun and clean it out each one by one and spark plug too then put them back and it should start and if it's completely dead then give it booster it should turn on get it the car drive it around it happens when you leave the car standing around for some time they just need to be used that's all I've had this car for 6 years you learn a few tricks and repairs when things happen also the 924S is known for problems after problems the crap is parts are expensive man always keep spare around for use and check your dip stick and coolant Everytime you going to use the car also they can leak from the power steering container make sure hoses are nice and secure if you feel they loose tighten them up a bit but not too much and belts as well

Also for like 20 bucks you can get a battery tester that test the Alternator and battery and it tells you which is failing and needs replacement just be patient with these cars trust me keep money aside just incase

So after all the things described above $509.00 to have the alarm removed and the re wiring done. They tell me the alternator is shot so I get that replaced $762 The car is still not starting every time. I hear a clicking sound from the fuse box under the steering wheel.

Power is not reaching the starting so when they removed the alarm they must have accidentally released a wire from the box check if you see any wire loose

I might have to take it back andet them check it. It's a Porsche Dealer and they maybe able to find the problem since they were in there less than a week ago.

Donaldx3

Yeah take it but take $$$ as well cuz at times they act like assess

Mikes88924S

Yeah I know they did cut the first trip down 10 hrs in the shop at $125 an hour to find out the alarm was the culprit removed it and re wired it they charged me $509
Thanks for your help I will let you know what happens next visit with them.

Good luck man and post some pixz of the car

Mikes88924S

Well I took it back to Porsche Dealer. Mechanic said that I would have to leave it there for a week or so. They said it could possibly be the sensors, also said I need a new wiring harness. I brought it home and continued to drive it just making sure I had ample time incase it did not start. And now it cranks and cranks and sometimes starts and shuts off in less than 2 seconds. Other than that it just cranks and cranks. I just started a new job and now have to line up a ride to and from work. Good news is the job is only 4 miles from home.

Wow damn good luck on that man hope you don't give up hope on the 924S and also lucky it's only 4 miles away ain't that far

No update(s)? Hoping you got it all sorted.

While this always seems hard to believe, I decided to follow the oft posted advice to be sure to avoid no-name/generic relays. My 928 would start and die within a couple of seconds and after replacing the fuel injection relay with a non-OEM relay I was still out of luck and turned my efforts in different directions. Still not having any luck, I decided to get an OEM relay and varoom! Troubles were over. Who knew? Actually, lots of people with heaps of more experience than I have....
