I think the fresh oil will be OK its not like your dumping 1 quart of dirty oil into the crankcase, but in the future you may consider changing the oil if it smells like old fuel or if it gets dirty in a relativly few short miles. Usually its best if a techron fuel system cleaner is added a few hundred miles before an oil change

Alright. Here is where I'm at.
Initially, the car started and ran like crap. I thought that was normal for a car sitting for so long but it died and won't start and remain running for any length of time.
I took my inductance tester and found that I'm getting good spark on all plugs.
Using a 60ml syringe, I shot a bit of fuel in the intake and it ran. As a matter of fact it ran and idled good, but died soon after. I did it again and kept it running, squirting a little fuel until the 60ml were gone.
I'm reading 35 psi at the fuel rail so that leaves the injectors, right?
I know a couple of injectors are working because if I wait between start, it'll roughly run for approx 4-5 sec. Unless it's the cold start valve that helping it along.
I'm thinking of getting a Noid light to isolate the injectors or signal to said injectors.

I really don't want to take the freaking injectors out, they are such a pain in the ****.

Cue the gallery....

I know you have good fuel pressure, but for fun, you might try doing the test where you redirect the fuel into the measuring cup as outlined in the WSM. Probably not it, but I'm just trying to think of things you can do without screwing with the injectors.

I assume if your inductance tester shows good, your system voltage is good? (I don't know, I'm not a real mechanic... just a "owner of broken down old cars" mechanic.)

GET A NOID LAMP at Auto Zone they rent them: Is this a 32 V; if so use the rear passanger inj you can get at to test it. Lamp should flash if it's getting a proper signal.
A short in "any" of the injectors wiring will shut the whole thing down.
Relay/Relay/Relay ?
Good luck

Angel. You could have some sediment / sludge at the inlet port of the injector. Some injectors have a very fine screen at the injector inlet as a last resort filter. I'm not sure about the injectors for the 84 but it's worth pulling one to check. Also, having the proper pressure doesn't mean you have adequate flow. Have you replaced the filter since it sat for so long? Did you treat the fuel with Stabil before it sat? If so, did you let the car run for awhile after dumping it into the tank? There are lots of possibilities as to what problem you have, but the good news is that it doesn't sound serious or expensive.

I am out of town at the moment. If you don't get it straightened out by this weekend, give me a call and I will swing by and give you a hand.

Not a 32V but gonna get a Noid, they don't look that expensive. ~$10

I checked #1 using WSM pg 24-116 Test Point 6.
The resistance I'm getting is ~3 ohms. Not good. Unless I'm doing it wrong but I doubt it. I had and extra one on the shelf and it measured the same. I'm too tired and frustrated right now so I'll check some others tomorrow.
I am getting BATT voltage at the injector harness plug.

Haven't replaced the filter. When I first started the car the Rail Endcap nut was loose and it was spraying like a MF. I think I'm getting good flow especially since the Fuel Pressure never drops.

When I did the Fuel Injector hose R&R I soaked the injectors in Carb Cleaner over night then rinsed them in Alcohol per my buddy's recommendation. I have a feeling the injectors are really, really stuck or AFU.

No Stabil. I siphoned all the gas out of the tank and used it in the mower. I did put some Seafoam in and 5 gal of New Premium gas in the car before I started.

I'd really like that. If I don't get it fix, at least I'll have someone to drink beer with.

I'm convinced that this is a fuel delivery issue. My guess, as I stated before, is that the injectors are stuck hard or gone bad, but all at once? Stranger things have happened.

If all my injectors are bad, I'm screwed. I'll have to find creative ways to earn the money and I'm not a handsome man.

tailpipe

if u think the injectors r bad u can do a redneck ultrasonic clean by dumping them all in a juice can of water and boiling them on the stove for 30 mins just don't let the wife catch u if there is old gas in them it will stink like crazy in the kitchen lol

I did a little research and found this site Manuals.type4.org/. It says that the injector impeadance should be "2-3 ohms between terminals on each injector". I may have been looking at the LH-Jetronic last night. Could the injectors actually be o.k.? I pray to the Almighty 928 Shrine that they are. *genuflect*
On my way home I will get a Noid light. Isn't that a cool word? I like saying it. "Noid", "noid". Heh, heh. "Noid".

Anyway, after I using the Search function I also found this thread started by Tom Rathjen that sounds a lot like my issue:
Fuel Injectors Not Firing.
While doing the interior, I did R&R some boxes. Would it be great if I only have to reseat the box.
Fingers Crossed!!

Avoid the noid.

Got the Niod and its blinking. Harness & computer working.

I pulled the entire Driver's side rail with injectors attached, removed Fuel Pump relay and had my neighbor turn it over while I listened. I could hear clicking. I would prefer to actually see spray but I'm not sure how to make that happen. I could try to rig something up but I'd probably blow myself up.

I'm thinking maybe large vacuum leak causing a lean condition.

Is there something I've missed? Am I assuming too much?

Can I get some suggestions of how to chase it down?

Fabio421

If you're worried about spraying fuel. Put the fuel pump relay back in, zip tie condoms over each injector tip and test to see if they are spraying. There is a measurement for how much fuel should be sprayed in a fixed amount of time but I'm not sure what it is. Do you have the WSM's? Heres a troubleshooting chart from the WSM. It may help you check off a few possible causes.

okay, seriously? CIS injectors, right?

I got a piece of 1 1/2" stiff foam and made a plug for the hole in the Air Guide Housing (Pet 107-15 Item 1) where the Air Flow Sensor (Pet 107-15 Item 7) goes in. I hooked up the air hose to the line that comes off the intake as shown in the WSM pg 24-119. While I shot some air, I could hear a big leak and my neighbor digging around found the leak around injector #3. I pulled the rail and found that the small O-ring missing on said injector. I know I put it on there before I started but that side is a PITA due to all the extra plumbing. Anyway, it either fell off or got sucked into the combustion chamber, never to be heard from again.

I called Roger and as always he answers his phone, despite it being me, and is going to overnight two of those little bastages. One for good luck.

Do you guys think that missing one small injector O-ring could pull enough un-metered air and not allow the car to run or should I look for more?

Angel84-928

Well my Peeps!

This time this Beeyotch is purring. After doing lots of troubleshooting it boiled down to stuck injectors. You can follow my madness in the "Can an AFM be adjusted or repaired?" thread.

I want to give a great BIG "Shout Out" to my Florida Posse because without their encouragement and assistance this Shark would have ended up as a mysterious insurance claim. Thank you Rennlist for your inputs and you're worth every penny.

You should see how this thing purrs. The motor mounts are doing their job. I can see the engine oscillate rhythmically as all 8 cylinders generate that beautiful rumbling that emits from exhaust.

I got the brakes bled thanks to my Man Fabio. He hooked me up with a Power Bleeder. It brakes nicely and runs sweet. The weird thing was that the fuel pressure would drop off when I turned off the car but after driving it around the hood it stays steady at 30 psi for about 20 min. Just like the WSM says.

I'd like to thank Roger for the parts and unsurpassed customer service.
