If you would disconnect the fuelline at the injectorrail and check for flow, you could immediately rule out: electrics, relay, fuelpump, in-tank pump (if present) filter, check valve and fuellines. This is if there is a good flow of course. Just remove the right black fuel-rail cover and disconnect the line on the front of the rail. Carefull you don't drop the small ball which is inside, which acts as a check valve. Have plenty of rags (and fire extinguicher just in case) ready and have someone start the car shortly. You should have a good clean flow of about 10-15cm. Extra CAREFULL though. Do NOT spill fuell on the engine!

It doesn't sound like your pump is acting up though. I had a broken fuelpump twice. First time it just cut out on me. End of story. No start or anything. Second time almost simular. The car almost started after several tries. But as I had been there before I had it diagnosed on the roadside in 5 mins.
You did however say you changed the fuel filter. Did you put it on the right way (sorry, have to ask). The pump is a delicate thing, as I discovered the hard way. A miniscule part of debris (like from changing a filter) can jam it. Either it works or it doesn't. When it would work only a little, as it would fit your symptoms, it would not pump enough fuel. This way it wouldn't cool by the fuelflow as it is designed to be and blow the fuse. It did when the problem occured with me the second time. It overheats fast!

Do the check I opted. It'll only take 5 mins. Good luck.

I rebuild LH ECUs, but I don't think this is the problem in this instance.

You don't mention any work on the ignition system. It sounds as though this may be the problem....

Check out the igntion leads, especially where they plug into the coils (driver's side is often a problem)

Le tus know how you get on. Start her up in the dark, and see if there are any fireworks in the engine bay.

I agree with John Speake.....If you have a problem like a bad distributor cap or plug wires, moisture settles in quite quickly. I would try starting it in the dark and look for under hood lightning, arcs from the ignition system. It also makes a difference as to where you are storing your 928...ie ..outside in the elements or inside where the conditions are somewhat controlled............goodluck

Bad _new_ gas maybe?

Storing it will cost as much as fixing it...maybe the fill jarred some jelled gas loose in the tank? Hope you figure it out and it is cheap to fix. We have all been there at one time or another.

you anywhere near Poughkeepsie?

I actually live 10 minutes from Poughkeepsie.

I checked under the hood (read the updated post about what happened)..no fireworks.. but she started up amazingly

Thanks for the tip.

the white smoke in the exhaust could be just residual water in the exhaust, however if you are saying it has a sulfur like smell then it is more likely a blown head gasket with water leaking into the cylinders.

time to pull the plugs and inspect them, as well as checking the oil for water and visa versa.

good luck and wish you the best.
