Car Forum / Porsche / Porshe 944 / March 2004944 help please
A few days ago my 1984 944 after running for a while just died and then would start and die start and die after about 6 times it was fine. Then just this evening my daughters and I were coming home from the theatre and it died while driving down the road then the same thing start and die for about 7 minutes or so. But fine right now. Fuel Pump????? Anyone have any idea or have experienced this I would appreciate your input thank you very much!!!!!!!!!!! DME Relay. Always carry a spare. It should be easy to find online with a Google search. f> A few days ago my 1984 944 after running for a while just died and f> then would start and die start and die after about 6 times it was f> fine.

Fuel Pump????? Anyone have any idea or have experienced this I would appreciate your input thank you very much!!!!!!!!!!! It definitely sounds like a fuel system problem - either the injectors or the system is losing pressure for some reason. Emanuel Signature1983 Porsche 911 1983 Porsche 944 If the relay doesn't work--- go to the fuel pressure regulator--- I was having a similar problem--- started with the fuel filter, opened up the gas tank to see if there was a blockage in there, bought a relay, even thought at one time that it was a temp sensor--- was the pressure regulator. Check out Clark's Garage (if you can't find it direct go to Pelican Parts) great source of information. Good luck-- 87 944 na > >A few days ago my 1984 944 after running for a while just died and then would start and die start and die after about 6 times it was fine.

It takes 3 thing for an engine to run , FUEL, AIR, SPARK, i WOULD CHECK 1ST LIKE YOU SAID FUEL, BAD OR COLLASPED HOSE, sometimes the hose comes apart from the inside and makes like a check valve of some sorts. Also check fuel pressure. If ok there check SPARK, AIR FLOW METER, ECT.. Hope this helps you some. Later Jack. definately fuel regulator...............exact same symptoms as a friends of mine. If fuel pressure is not regulated and becomes too high, injectors draw more current. DME recoginzes this increase and shuts the injectors down. Check fuel rail pressure. good luck Mark > It takes 3 thing for an engine to run , FUEL, AIR, SPARK, i WOULD CHECK 1ST LIKE YOU SAID FUEL, BAD OR COLLASPED HOSE, sometimes the hose comes apart from the inside and makes like a check valve of some sorts. Also check fuel pressure. If ok there check SPARK, AIR FLOW METER, ECT.. Hope this helps you some. Later Jack. Really an easy way to check the fuel regulator w/o any special meters or equipment. Pull the electrical plug off of one of the injectors. If the car then runs, it's the regulator. M> definately fuel regulator...............exact same symptoms as a M> friends of mine.

SignatureJack I just finished working on an intermittent problem on my 944. I checked the connection between the negative of the battery and the engine. There was more resistance there than to chassis ground. What I finally found was that the connection to the engine had become corroded. After cleaning it has been fine. The connection is near the position sensors on the bell housing. However it is on the engine. > A few days ago my 1984 944 after running for a while just died and then would start and die start and die after about 6 times it was fine.
