ok I need someone to point me in the right direction to see what I am missing or overlooking on this.

this is a 1982 Porsche 924 non turbo model. it was running about two years ago then wouldn't get fuel to start when I was moving so I towed it over here and haven't used it since then ........ but now I need it.....the car will start for just a second then die or not start at all. I know it has to be a fuel problem . I drained the tank and put in 2-3 gallons new fuel , replaced the internal fuel pump thinking that's what it was , nope. next I replaced the external pump with a good used one off my 944 the old 924 pump seemed to be clogged with trash and now I get fuel up to the fuel distributor block (which is leaking fuel out of the screws that hold it together) ANY IDEAS????

I haven't been in a big rush before now to get this car running as I didn't need the extra vehicle but now I need to get it running asap so I can pull it out side to sand blast and paint and use for a daily driver for a few weeks the reason is I have to take the 944 off the road and pull the transsaxle, mufflers and stuff just to get the old fuel tank out which has a huge hole streaming gas out of it and I need it out to weld it or replace it and I am not sure how long it will take to do that . I need it fixed before I send my son off to college in august with it but still need a daily driver while I work on the 944 so I have to get this 924 running quick (I know last minute things suck but it is what it is)

Is it for sure leaking out of the screw holes that hold it together, or is it leaking out of the banjo bolt holes? If it's leaking out of the screws that hold it together, it needs to come apart and be resealed for sure. If it's only leaking out of the banjo bolts, then you either have loose banjo bolts and/or bad sealing washers that need replaced.

With things being clogged/bad, you most likely have a clogged Warm Up Regulator (WUR) too. Those can be cleaned and reused as long as they test good electrically for resistance. Here's my WUR tear apart thread with pics here. You will want to pay attention to the inlet filter (pop it out from the backside and either clean or throw it away) and make sure the thin metal round disc is clean before reassembly.

Trying to fix fuel issues on these mechanical injection cars without a fuel system tester is futile. Get one from Dan (ideola is his user name here, or visit http://garage.ideola.com/ if you want to buy one). Ask/search how to use them here, there have been some pretty good write ups on them.

it is defiantly leaking form around the treads of the bolts that come form the bottom half to the top and hold the dizzy together. The seam between the two half's and the injector line bolts (I think is what your calling banjo bolts) are fine and not leaking. I mite have to take it apart again and put some type of sealer in the threads but I'll wait and see if 924guy has one for me to try to see it that is my issue or not


I looked at your other thread on the WUR but can't find that in my haynes manual or locate anything that looks like that on my car. My ability and knowledge of these cars is limited

The WUR is also called a Control Pressure Regulater (yay for consistent naming). It is mounted on the back of the intake manifold almost underneath the distributor.

I replaced the fuel distributor block (dizzy) today on the 924 and it stopped the leak but doesn't make any difference in the problem , the car still start for just a few seconds some times and others it just turns over, I tried cleaning the disturber cap contacts but that didn't help either , any ideas what to try next?

I did find the fuel control pressure regulator in the manual and located what appears to be it on the car but it is not the rectangular shape one like pictured in the other post it looks like a small round cylinder with the return fuel lines connected and also connected to the base area of the air butterfly valve right under the rubber air boot. this cylinder unit does not look like it can be taken apart to clean at all

The WUR is underneath the coil bolted to the side of the far manifold runner. Get right in there with a torch and you'll see it. It's a pig to get to and you WILL drop one of the bolts or washers into the abyss so get a cloth or something down there to catch it. Take the coil off as well for access and count your scratches afterwards.

I recommend that you push out or pick out the fine mesh filters on the fuel inlet to the WUR. There are about 5 layers of increasingly fine mesh which are very difficult to clean between properly. Either spend a lot of time making sure each individual layer is completely clean or run without it. I suggest that the first thing you do is pick out the filters and see how it goes before you open the thing up. If you do that you will need to reset the cold/hot control pressures which is time consuming though not impossible.

Have you got yourself a CIS pressure tester yet? You cannot do this job properly and know that you have done it correctly without one so please don't try. It will reward you many times over because a correctly adjusted CIS system in good condition is a damned fine injection system for a stock engine. Don't let anyone persuade you to bodge the symptoms to mask the problem.

I think some guys here have had some luck just soaking the WUR in carb cleaner but I have tried this in the past on a number of units and never got close to cleaning the mesh properly that way.

Good luck.

Is there fuel comming out of the injectors of your Porsche? If that's the case, you fuel distributor seems good to me. But in that case I guess you have an other problem.

If it is, but it is only running for a few seconds I suspect it is running on the cold start valve, and when that stops, there isn't fuel from another source to keep the engine turning.

So before you're going to replace a lot of parts it is nesscary to know what is working and what isn't.
