Thanks everyone, for your input!!
I'll test the relay tomorrow (car is not at my home). I didn't think about the fuel pump itself going
ugh.
Umm well the car had a new radiator put in, and to clarify, it's the cooling fan for the radiator not working, not the one for the A/C. We looked for a toggle switch for the fan but couldn't find one.
Okay: so I'll update tomorrow. Thanks again ^^ I'll post pics when the car is safely in my garage.

Cars that have been sitting for a long time often suffer from fuel-related problems. CIS cars (like yours) need to be driven regularly to keep the fuel system internals from drying out and cracking. Unfortunately, dried-out and cracked o-rings and seals in the fuel system don't heal themselves once fresh fuel is re-introduced. Small bits of the o-rings flake off and plug little rusted screens, wedge in the bores of the pistons in the airflow meter/fuel distributor/metering unit. Stuff like that. If it were my car, I'd have all that stuff out for disassembly and thorough cleaning, and replacement of all the soft parts. The tank would get flushed, suction strainer on the pump would get replaced along with the fuel filter. System would get pressurized and control pressures would be checked. Then.... Then I might try to start it for the first time.
Then again, I'm just deathly afraid of getting stranded by the car, out someplace bad, with the lions and tigers and bears (oh my!) and tow truch drivers lurking and trolling for stranded exotics. I'd rather get stranded in my own garage, closer to the fridge and the tool collection, apparently.
Welcome to the asylum, by the way!

The fan behind the radiator should run when ever the engine is running. If there is not a fan belt on the fan then it has been converted to electric fans and anything goes!
But in any case, welcome.
I would say that if you are A)not knowledgeable about cars C) not flush with CASH, this may not be the car for you.
Having said that if you are willing to learn and this is a second car (or at least you have backup transportation) and not afraid of getting a little dirty, it can be a hella great ride.

HI CAT!
welcome to the family, so to speak......
you car will have CIS injection, which means you can do great things with it without having the electrical headaches of L-Jet.
if you don't have a copy of the Factory Workshop Manuals---get them on CD from Jim Morehouse----this is a must have.
CIS injection is prone to very bad things if you don't keep the fuel very clean-(change the fuel filter regularly-use fuel injector treatment regularly).
your electric fan (in front of the radiator) is for the A/C, not cooling the engine per se.
Don't be afraid to ask any questions here---lots of people more knowledgeable than me for most any issues.
Get in touch with other local 928 owners--they can help, and are usually most willing to do so.
Good luck!!

Hi,
Before targeting the fuel pump, you should change the fuel filter. Do you know any more about how often or how recently the car was driven? As others indicated CIS injected cars hate to sit. THey have a number of screens in the fuel system. When they do their job of trapping debris before it ruins the big dollar components like the fuel distributor, they also get occluded and block flow. Adding stom Stabil to the gas may be a good initial measure if its been parked for a long time. I'd hold off on injector cleaner 'til you get it squared away, because it can dislodge more sediment and debris and cause more problems.
Also, for the intermittent running problems-- check the green trigger wire. There is a wire that runs from the ignition box on the passenger fender, across the front of the engine, and plugs into the distributor. It has a thin coating that gets degraded over time and can expose the wire, and repeated work can cause the internal windings to fray. Just give it a visual inspection and see whether moving it around changes the car's behavior.
Its great that you got a car that had the timing belt and water pump serviced. Do you know whether your car is US or EUro spec? Pictures would help us identify that for you, or just check the VIN number. IF it has a series of three 'Z's, then its a Euro and an even better score. But you could then have a higher compression interference motor which would make the timing belt even more critical than otherwise. Just factors to consider, you may want to find out who/where did the service, and if there is anything questionable about the installer's proficiency, get the belt tension checked. Should be rechecked after install anyway.
Other questions, always willing to field emails.
Regards from the 'right' coast

Since you were messing with the fuses before the car refused to start, I would start by looking at the fusebox...
However, 928s in the rain frequently turn out to need new spark plug wires, distributor cap and rotor. Wet wires can lead to a no spark issue. Use a hair dryer on the cap and the coil to see if this will restore spark. It often will, if this is your problem. LOL
As has been said, the basic question is, No fuel ? Or No spark ?

Hello Catherine welcome, something you will need is a copy of the service manual on CD for a detailed reference when the good folks here are trying to help you.
Don't feel bad it took me 7 months ( of on and off working on it )to get mine running with my last electrical problem but the guys here got me back on the road.
Regards
Matt
