    it seems if you disconnect ground wire from battery and leave it off for about 5 min. it will then start right up. must be restarting the computer . Does that mean it needs a new computer ? Or is it one of the sensors ?

Sounds like a fuel filter problem, or fuel pump. Also have you ever had the injectors checked? I had the problem you've described and found both the fuel filter needed replaced, and the injectors cleaned and adjusted.

Testimonial: "Maybe. Still driving it.Only breaks down when the daughter drives it. i have driven it for two weeks now and it starts every time. Figured i would drive it till it quits so i can fix it."

    Hi Again. Did you know that some older vechiles with fuel injection systems will "Flood Out" if you press the gas while trying to start? My Porsche (and Ford Ranger) will do the same. I believe the Owners Manual states: "Put the gear shift into neutral, depress the clutch (especially in cold weather), and start! It doesn't include pressing the gas pedal! There is a memory circuit in the ECU that "remembers" the correct fuel to air ratio for running/starting. Depressing the gas pedal causes the memory to be erased, and the car will flood. DO NOT pump the gas pedal... it will make matters worse. I personelly went through this problem with my Porsche, and my Ford Ranger!

Hi, You need to get your timing belt checked. Dont attempt to start the engine until your timing pullys are reset because if your cam is set wrong it WILL cause valve damage.If it is allready correctly set then i suggest you test the compresion in case damage was caused when belt was fitted. Hope all works out ok 4 you.All the best.Phil

SOURCE: 1983 Porsche 944 coil goes bad, just replace coil

What do you mean by bad? Does it measure a different resistance.

Here is the thing on coils, I do not understand why they are not made differently, but

coils are to be run at a lower voltage, often. some like older cars, no more than 8 volts....Think about it...That is a LOT of resistance to scrub down to 8 volts, hello? the system is 13.8 to 14.9 volts NORMAL.....

But I digress.

These resistors fail and the amount that they should do, they cannot do.
One thing that I do as a diagnostic test is to buy a coil, any coil with an INTERNAL resistor. So, I can put full sysytem voltage to it....If it lasts, investigate the viotage available at the coil.

1984 Porsche 944 no turbo automatic. Will not crank over, I have power out of the ignition, but not to the starter.


Hello there
Most likely it is your electric part of the igniton switch.It is not hard to replace.
That is what you should try first.
