No chance the parts came here and no one was here to sign. I was here all day and besides, I specifically told Roger to make sure no signature was necessary just for that reason.

I'm going to replace the filter now.

And I agree, a reliable daily driver is my next step.

Anyone want a beautiful S4?

tie rags around you wrists so gas wont flow down your arms, wear gloves

Guess what it ISN'T...the fuel filter.

I suspected that the filter was fine when it was full of gas and flowing freely out of the exit tube.

Since I have no other parts, that's it for this week.

I'm suspect that it isn't fuel delivery. I don't know why I feel that way, I just have a hunch (that coming from a complete idiot when it comes to 928's, so take it from wence it came).

Is there a possibility that it's electrical not fuel?

The fuses and relays check out, but when Mike removed the front of the injector tube, no fuel was present.

My question is, is there any other reason that fuel won't be in the injector tubes besides fuel filter and pump???

UGH

And thanks Peter, I actually bought my 944 Turbo from Body Motion, they are good guys but expensive.

I'm trying to keep the cost down so I guess the fuel pump is next in this series...well as soon as the frikin parts decide to show up!

Mrmerlin

the other thing you can try is to remove the fuel pump/ filter assembly from the tank ,
plug the outflow line from the tank,
then work on the pump N filter on the bench.
remove the fuel pump from the frame and run it backwards,cycle Marvel Mystery oil through it.
You will be looking for debris coming out of the pump if you find any then dont let them get cycled back through ,

and please verify that you dont have an internal pump in the tank.

you will need a 16 oz cup to do this and a power supply.
dont work on the pump with it attached to the car as a spark could send it up in flames.
be very careful screwing the nuts onto the pump leads they have aluminum threads and will shear off if overtightened

If the tank is full of gasoline its possible to leave the rubber line in place, squeezing it closed with vicegrips with rubber hoses on jaws, or similar arrangement. That way you can remove the pump and leave gas in the tank. But be careful.

There are probably zoning restrictions in your area prohibiting outside burning without a permit.

I'm also not convinced you don't have a double pumper.

Also, fuel filter is low, so gravity will fill it. Fuel rail is high. Must have pump working to get gasoline up there.

I'd put serious money on the pump being the problem. (Ask me how I know).
The bench and reverse might work, but if you're going to that much work, just replace the damn thing and be done with it for another twenty years.....

If you measured pressure at the rail and there was none, and the filter flows fuel, then your pump is definitely the issue, unless you jacked the car up with a pad pushing directly on the hard line under the car and pinched it shut?

Following Stan's advice to bench test may get you some more mileage out of your old pump..

But be warned, the two people I know who've done this both suffered fuel pump failure a second time within a few months, and ordered new pumps to replace. One of them had poor running symptoms (CIS car) after unjamming the pump, before the second failure - we haven't had time to determine the poor-running was a direct result of fuel pump crapping out again, as the new pump only arrived a few days ago, but it does seem highly likely that low fuel pressure caused the symptoms.

In my opinion, bench testing the old pump to try unjamming it is only worth it as a diagnostic exercise - if it un-jams and the car runs ok, I'd still replace the pump with a new one for peace of mind.

Trusting a 25 year old fuel pump to keep running indefinitely isn't a good idea, especially if its one that already failed once. I'd only consider it if I carried a spare new fuel pump in the car, and was prepared to swap fuel pumps at the road side.

I truely hope you're right. The pump and other parts will be here hopefully tomorrow. Next weekend I'll replace everything and it will be good for another 25.

By the way, and I've said this before, once you get a couple of bugs worked out, these are reliable cars. I'm doing 10 - 12 thou a year, daily driver as long as the salt's off the road, and I've had one real issue (other than the maintenance) that caught me off guard. (The bloody fuel pump).
Bought mine on a flier with only a cursory self done PPI, and I couldn't be happier. My personal opinion, given the work that's already gone into the car, if you give up now, you're the big loser in the transaction. (Just my opinion though).

What a bummer... I was expecting to see a post about how things were fixed and all was good. Hang in there, Steve. If the fuel is flowing out of the filter, but not out at the engine, it's got to be a pump or pump-related issue.

You'll have it licked in no time... promise.

norcoastal

Well it's fixed and running strong!

It WAS the pump.

I changed the pump and the filter, it starts right up and idles fine.

I couldn't have done it without Mike Frye. He spent two of his weekend days helping me determine what the problem was and helped me fix it.

Thank you very much Mike, I owe you!!!

Here's the bad news...I'm nervous about the car. I need a reliable car to get me to the train, and sadly, this ain't it.

The past two weeks taking cabs and waking my daughter up at 5:45am to take me to the train has opened my eyes up that I need something newer, somethig that I don't have to worry about.

I feel now that I'm just driving it until the next problem occurs. That's not good. And that's not enjoyable.

Andrew sold it to me for $11,000. Any Rennlister can have it for the same, I've only had it for 2 1/2 months and it still has just 95,000 miles.

It's worth much more. If you know the car, Andrew put a TON of work into it and I just replaced the fuel filter and fuel pump.

This should be fine for a long time.

It's going on eBay today.

If anyone is interested, let me know.

Thanks again Mike. You're an outstanding guy!!!

Mrmerlin

Steve, ah , I think you ought to give this a chance,
if this is a car you really like,
driving it should make it run better,
from the info provided it sounds like most of the deferred things have been fixed and you will have a reliable DD.
You have to make the call however

dcrasta

wow... Might not be the car for you, if you're throwing in the towel after only one round. Did you discover something else ?

Hilton

Congratulations on getting it running.

After all that - it should now be reliable. Assuming you've put new relays in as well as a new pump, there's not much else left to fail on there

Can't you buy a cheapo $2k honda civic for reliable station transport? and keep the 928?
