It won't run

My 94 D-90 has been sitting for nearly a year, and I started it maybe once or twice in all that time. Now, I need to get it going again while my primary car is in the shop.

It turns over, but dies. I sprayed starting fluid in the plenum, and it'll run just long enough for the fluid to run out. I've got to imagine that the old gas has gunked something up. I sprayed some carb cleaner in the plenum too, but no lasting effect.

Could use some suggestions on how to getter going again.

Thanks

Turns over? Ran at all prior to starting fluids? Do you hear your fuel pump? Any chance you have a fuel pressure test gauge? If it's getting fuel, did you store it with a stabilizer? If not, throw so iso in there ASAP.

One year old fuel isn't that old.
And you say you started it a couple times in that period?

Something else going on...

If it starts and dies, that means the fuel pump is working a little bit and you have spark momentarily. Try starting and giving a smidge of throttle ~2k rpm and see if it stays running. If so, remove and clean the stepper motor aka idle air control valve. If not, my guess is ignition module. I had the same issue with my yellow 95 and there were two things. Some pick up in the distributor was bad (apparently this kicks in only once started per my mechanic) and a short which killed the ignition module.

If I disconnect the fuel supply at the manifold rail, and turn on the key so the fuel pump runs, shouldn't I see a steady stream of fuel? It just sorta spurts lightly.

How do I jumper the fuel relay to jet the tank pump to run continuously? (Isn't that the only electrically powered pump?)

You;ll probably convince yourself to order replacement parts like coil, Dizzy cap, wires etc. :just in case: and thats ok. Check the wiring including grounds for mouse etc damage and good connections

It should spurt and then stop if the key is just turned on. Yes there is only one pump.

Obviously, you guys think that I must know my ass from a hole in the ground, and have an ounce of common sense. You're wrong.

After reading efilfij's post, I thought that I'd check further up-stream in the fuel flow. I could hear the tank pump whirring, so I knew that it's ok. I disconnected the fuel filter and couldn't get any fuel out of it either. Dammit. Spiders crawled inside the tube and clogged the damn thing up, I thought! I do NOT want to drop that damn tank again. Can I blow it out with compressed air? Hmm. I wonder how much fuel is in the tank. (My gauge has been broken for years.)

Earlier today, I snaked a line part way down the filler hose and saw some wetness, so I thought it was pretty full. This time, I put a straightened coat hanger all the way down, into the tank and it was .... BONE DRY.

So, I poured in a few gallons of fresh gas, then checked the fuel pump at the disconnected fuel rail, and it looked like Old Faithful. Reconnected the fuel line and... it started right up!

What a dumbass! Ha.

I thought you guys might get a kick out of my jackass troubleshooting today. The D runs great. Got the cobwebs off of it and taking it for inspection tomorrow. You'll see Big Red on the streets of NoVA for a few months. Thanks for indulging me

Props to Foreign Car Service in Alexandria.
