1977 Porsche 924 New fuel pump and filter no gas just air.

I have a 1977 Porsche 924,I just put a new fuel pump on and a new fuel filter, all I seem to be getting is air and a tiny bit of gas, this is right after the fuel filter before it even touches the engine, The car wont start, could something be clogged, maybe the fuel accumulator's or the fuel silencer? Or could it be the fuel sending unit? Anyone else have this issue? By the way I just bought the car and I was told its been sitting for over a year, I replaced the fuel pump right away and drove it 3 miles, It sat, a few days later it stalled, so I put another new fuel pump in, it has 1/2 tank of fresh gas in it, and yes most all I am getting is air now instead of gas.

    The gas sensor has a rod in the middle, It was rusted so the Fuel gauge was reading 1/2 tank, turned out I had no gas.

I would check the fuel lines where they attach to the sending unit. The rubber inside of the nylon weave is probably rotten and sucking air instead of pulling the fuel up and out of the tank.

    Yes my next task is replacing all the fuel lines. My tank is full of black particles car dies all the time. I cleaned the tank one time and it ran like a dream till it filled up with the same black crud.

To save you all the hassle check your spark plugs & distributor first if you are getting a spark. To do that first take out the number one spark plug wire it will be the one closest to the distributor. Second take out the spark plug, then put the spark plug in the spark plug wire. Turn on the engine u should see a spark at the spark plug if your distributor is ok and spark plug. If not replace your distributor.

These is because of the improper combustion, so you better check the air filter and the exhaust along with that you replace all the spark plugs

84 porsche 944 replaced new spark plugs and wires,cap,rotor,coil,emc,DME relay,fuel pump, reference speed sensors, new battery, and still no start. Any suggestions is what to do next?

Not much left unchanged is there and no doubt you have done compression testing on all 4 cylinders as well. (If not you need to). I assume it is cranking over normally with the starter motor but not firing.

I would try one of the Porsche Owners Forums for this as one of the other 944 owners there should be able to help..... Like this one..................

My 2001 Chevy Cavalier acts like it is not getting gas, a new fuel pump and fuel filter and line was put on and it quit again on me, another fuel pump, spark plugs or points was put on and still will

Check your lines, specifically where your filter housing goes into the fuel tank. I had the same issue and I just had to replace that filter along with a hose. It seems the line somehow got clogged. I hope you find this helpful.

Okay, you need to make sure the fuel pump is getting power and that you have the lines hooked up correctly. Also, when you replace fuel pumps you need to remove the air cleaner and use starter fluid to get the engine started.

Replaced failed starter with new one on my 1977 porche 924, turn key and nothing. I have a fully charged battery.

check power and ground cables for fit and corrosion. If ok check starter switch wire(the little one) for voltage when key is turned,if none is ignition fuse/switch problem.

Hi Nick. you need a 12 volt battery of this size:
  • Length: 11.5625 in
  • Width: 6.875 in
  • Height: 6.875 in
  • to fit into your space. bring the old one to your parts store if possible. clean the terminals with wire wool or scotch bright and apply Vaseline petroleum jelly to them after fitting. Cover the top with a plastic sheet or something, corrugated plastic is good, if it does not already have a cover. For your fuel pump any model 924 pump that has the same pipe connection will work, the wiring is simple and the same on them all. You also need to check your fuel pump relay and check that the fuel pump has 12volts supply and a good earth
