Hi again. I am completely carb illeterate, and am in need of some advice.

The story with my friends 84 GS is that it had been sitting up for three years. I cleaned the gas tank out the other day, which was freaking horrible. I doubt I could even measure the amount of **** that came out of that tank.

I put on a new fuel filter, and about 3 gallons worth of gas in the tank.

The car will start, and run if I pour gas in the carb, or spray brake cleaner in the carb, but it won't run on its own.

What should I do next? I figure the problem is either clogged lines, the need for more gas, or carb problems. What can I do to figure things out? I am really smart when it comes to cars, but I've had no experience with carbureators yet. Thanks.

your float bowls and fuel inlets are probobley all clogged up. pull it apart and soak it in parts cleaner, and scrub the **** out of it all...



then if you get it running run a tank of supreme fuel through it and a good fuel system cleaner.



good luck

how about the fuel pump? I'd probably buy a kit a rebuild that carb too...

I forgot to put in the original post that the fuel pump could also be suspect.

How hard is it to take off/apart the carb?

I'd first try just pulling the top of the carb off and cleaning out the float bowls, and the needles and seats. There are also some little strainer looking deals where the fuel lines go into the carb, they could be clogged with ****.

Cool, I'll give that a shot. Thanks.

Is that Ren from "Ren and Stimpy"?

You eeediot!

you said you put a new filter on. was it the one under the hood or the one by the tank. if the tank was that bad id say that both need changing, and yeah check both needles under the floats.

I had this probelm when I first got my 7 ...the floats were sticking so instead of wasting my time with a stock carb...

i got a RB intake..Holley 600 double pumper.....Holley Blue fuel pump...and that was the end of that problem..



and I still can use them parts on my next upgrade...

That is Wren. Funny story: where I work, there is a small wiry guy, and a big STINKY guy working with us. We call them Wren and Stenchy.



Ok, I cleaned out the strainers on the fuel line banjo bolts, changed the fuel filter under the car, cleaned out the float bowls and everything else with the top of the carb off. The car still wouldn't fire up. It's got good compression. The battery was dying when I was trying to start it, so I didn't get that much time to try to start it. I'm going to check the fuel pump in the next couple of days.

What's the best/easiest way to find out if the fuel pump is any good? I figured, I would first, just turn on the key, and see if I could hear it running. Thanks again.

My car needs a good charge once my oil cooler gets here.I just bomb start it when the battery is dead.Fires up nicely.Just give it some good gas. https://www.nopistons.com/forums/pub...#>/biggrin.png

to check for operational fuel pump, pull off the fuel line going into carb (the large hose closest to windshield) put a small container under hose and turn key on, should see gas flowing from hose at this point,,,if u are getting gas, try pouring an ounce of fuel down carb throat and see if it will run,,,have u messed with the adjustment screws yet at base of carb,,,do u have a haynes or can u get one from the library....let us know how ur comming along,,we are here for ya....... :wave:

I haven't gotten a haynes manual yet, but I probably will. I haven't messed with any adjustment screws yet. And if I pour gas into the carb, or spray brake cleaner into the carb, the engine runs pretty good. I'm going to testr the fuel pump pretty soon.

the 84-85's have a fuel pump relay, they only pump gas when it gets an rpm signal. you have a plethora of options

1. the fuel pump plug is under the driver side bin, just jump it

2. pull the line off and crank engine

3. jump the relay, its in the dash by the drivers left knee

4. take distributor out, turn key on, spin it by hand

5. replace pump and recheck

hmmmmmm. That's interesting. The tach doesn't work on his car. I wonder if that is the reason for all of this crap.

The tach problem can be a bad ignotor..on the dizzy..

Could someone give me a better description of where the relay is? I was looking up under there a few minutes ago, and found the check lamp indicator relay. I found another relay above the brake pedal, under the steering column that was round and metal. And I found a harness plug dangling on the right side with nothing connected. Any help is always appreciated.

Any more description of the relay would be cool. Or maybe what color wires go to it.

the fuel pump relay, is under the dash. if you are sitting in the driver seat, its on the right hand side of the steering column. the relay itself is 4 pin and its round. it has a little tab with a 6mm bolt holding it to the dash



mike

Hmmm. Interesting. On the right side, underneath the dash, is a harness plug for a relay. I wonder if it is for the fuel pump relay. I didn't see any other relays on the right of the steering column. There was one, all the way up under the dash, really close to the column that was round, but held on by a 10mm nut. I took off the cover and pushed the plunger down, but didn't hear anything from the pump.

i think the next step is to take the drivers side bin out and jump the fuel pump.



mike

Thanks Mike. That's what I'll do next.

if that works the fuel pump is good and you need to look at the triggering part of the system.



mike

I took the bin out, but there are a whole lot of wires in there. Which ones should I jump?

its a 2 pin connector that goes down thru the floor, the fuel pump is right under that



mike

I connected the fuel pump directly to a battery, and nothing happened. So I'm guessing that would be the problem.

yessir!
