So next-next weekend i'll be taking a look at a 924 down in Austin. Talked to owner and here's the sit rep-

'82 5 speed

Owned by a mechanic before this guy got it. Sat for 11 years, but was somewhat taken care of during it's stint in the garage. Body, electrical, engine and trans in good nick, starts but does not run. So far he has cleaned the tank, cleaned injectors, replaced fuel pumps, replaced starter, cleaned up the brakes, replaced some sound deader and a few other little things. Has stated the vauccum lines are old and thinks this may be the primary cause of the car dying when it's given gas. (From what I know about CIS this is a major aspect of a car responding like he is describing it.)

Seller bought it as a project, wanted to swap a V8 but decided it was too nice to do that. Says he's a bike mechanic, and perhaps could resolve the not running issue but he is very limited on time. He's moving to houston very soon but will be back and forth, but is pretty motivated since it's sitting at a friend's house.

So thoughts on the initial run down of the car?

I'm no CIS wizard, and will be picking up copies of the Haynes 924 and the Bosch book, before I head down- shipping permitting.

Am I close in thinking the vauccum lines are the primary culprit? What else could it be or what else in addition to the lines?

I could probably borrow a friend's driveway for a bit, but somepoint soon after it would need to make the trip back to dallas, under it's own power would be a helluva lot easier.

Thanks guys! Let's see if try #2 works out a little better...

Also anyone in Austin that might be able to lend a hand at some point in the process?

11 years is a long time! My guess is that the CSV is starting the engine, but the CIS distributor might be varnished to the point of not transfering fuel to the injectors. Have the dude (we're in Texas of course!) pull an injector and turn the engine over. If no fuel, then, start there. Spendy cleanup job on the distributor if sent away.

Maybe it has a bad fuel pump relay. The fuel pump relay needs the distributor signal to latch closed and keep the car running. If there is no signal it will start and not run.

CSV, cold start correct?

I read through the FAQ again but still don't fully grasp the system. I'm ordering the books today and should have at least a good couple hours on the way down to read them

I could pick it up in a couple minutes if I could see it, but scanning through various posts picking up bits here and there isn't helping me get a complete picture.

I'll see if I can get the owner to run through a few things, otherwise I'll make a list for when I'm down there.

Although I could probably get a friend to tow, and the owner has expressed the possibility of towing it for me, between gas and renting a trailer I'd probably be out a couple hundred bucks that could be better spent on the actual car...

It will all just depend on the car when I see it. It sounds/looks like it will be a good base for a project. Now I just have to wait for more than a week... better order those books now...

Hmm Fuel pump relay sounds like something that might be good to order and have with me to swap out and try, unless there's a free way to jump the connections or something and find out if that's it?

I'll see if he can pull an injector before I get ahead of myself though.

Suspect the WUR as well. This controls fuel enrichment according to engine temperature and time since start. It is almost certainly gummed up and will need cleaning/replacement. Do a search on WUR - there's a lot about them on here. Get or borrow a CIS fuel pressure tester as well; you will be glad that you did. If you don't then you are working in the dark.
