Well, heres the basics. 82 stock 350 Crossfire.

Yesterday I was out driving around and was heading back to the house. Ended up behind a few at a light and it started to quit. Pumping the throttle, I got it inot parking lot just down the street from the house.

Got it started long enough to continuously pump the throttle to get it back to the house without quiting. if I let it idle-it wouldn't. Left it until this monring and will start on the basics. Got new air filters and tried starting. It will start up and run for maybe 5 seconds and quit.

So next is the fuel filter and O2 sensor. Could be a fuel pump but hoping to avoid that. I'm going to get the basics out of the way before I get serious. Any ideas? Thanks

 

I'd check fuel pressure before and after fuel filter change. Since it starts and runs, sounds like fuel starvation to me.

 

THats kind of what I think. If I pump the throttle, I can pump the rpms way up and nearly sound like a normal over rev if you know what I mean. Thanks.

 

Well here is where I'm at. I changed the filter-nothing but at least I have a new filter so no big deal. Now here is where i caught on to something. Tried starting it and the same thing, start it up and would run and sound good for about 3-5 seconds and stop. I did this ten times.

Now I don't know what possesed me to do what I did next but just as aprocess of elimination. I took the fuel cap off and stuck a screw driver in it to hold the metal flap open. Started it up and stayed running. Was running very rough but running asuming the engine was drawing the fuel instead of by pressure. So from this "barnyard" side of it, Sounds like i need a fuel pump.

What do you all think?

 

I think it is blockage in the injection system.
If you have some buildup in there it will not idle but will run rough if you press on the gas.
I would first spray carb cleaner etc and also add a couple of injection cleaners to the tank and see if it helps.
Usually fuel pumps just quit without any warning.

One other thing, if this only happens when the enginge has been running for awhile check to see if your fuel line is touching the block.
This can cause problems all by itself.

Don't replace the pump 'til you check the pressure.

 

okay

 

Wouild you happen to know where the Oxygen Sensor is? It's not jumping out at me. Thanks

 

Should be somewhere between the exhaust manifold and the cat. Expect it to be close to the manifold.

 

It's in the left headpipe just below the exhaust manifold facing to the rear.
