84 Porsche944

[tracfuel]

If anyone can help me out with this one I would greatly apreciate your help.
I have a 84 944 that I drove 9 miles from my house I sold to my new house im at now I parked it in my garage 4 years ago.Today I was out tinkering around in the garage and thought I would play around with the 944.I went and bought a new battery put it in and put the key in the ignition the stereo came on and the bell was dinging when I turned the key to start it up all I could get it to do is turn over but no start.I checked the fuel gauge and it shows a half a tank of gas in it.I did notice that the tach stays at 0 no movement at all. I don't understand why it will not start since it was running when I parked it? Please help!!!!

Thanx in advance

Is the gas that is in the car 4 yrs old? If so the gas is bad. It looses it's ability to ignite after time. I have let gas go for a year and it was still ok. After 2 years, no fire. I do not know if your car is fuel injected or carb. If it is a carb, It will probably have to be cleaned from the varnish the old gas has left. Either way you need to get the old gas out and put some new stuff in. See if it will run on the new gas. The tach will not work untill the car is running.

Well I was able to remove all the old gas from the tank and I put fresh gas in it. I recharged the battery and it still will not start I pulled a plug and I have no spark. I allso noticed when I turn the ignition key to the on position not cranking it just to the on I can not here the gas pump come on I took the cap off the end of the fuel raile when I turn the key on no fuel but when I crank it fuel comes out.

I am new to the porsche scene but let me try to help. Sounds like you have fuel injection if you have a fuel rail. A couple of things come to mind. First you need roughly 40 to 60 psi of fuel pressure to the rail if the injectors are going to work properly. I do not know but it is possible there is a pressure switch that goes to the computer. If there is not enough pressure, the computer might be shutting down the ignition system. I would go to the fuse box and look for the fuel pump fuse. The fuse might be good but i would try to measure the voltage at the fuse to make sure the ignition key turns it on. The other thing i was wondering about is if a little critter decided that your car was lunch. Knowing that the car ran before it went into storage and now it does not, what changed. I had that happen to my road runner once. I do not know where the fuel pump is on your car, possibly on top of the fuel tank? Can you measure the voltage at the fuel pump? Maybe the pump froze up over the 4 years. When the car was cranking, did the fuel come out in dribbles or at a steady stream? Again bear with me but i am just throwing ideas out.

Ive had to take my fuel rail off many times to braze a leak...got another fuel rail off ebay and had to keep on switching them cuz they would both start leaking...but anyways when you open up the fuel rail it should be spraying out gas...i would check the fuses and those modules that are in the fuse block...if your not getting spark and the fuel only runs when the keys at start then it definetly sounds like electrical/loose wires maybe...good luck
