Ok, I had a thread about a week ago saying my truck was sputtering and not wanting to run. It ran good for a few days after some tinkering and it starts again. I figured i wasnt getting good spark so I just put new plug wires a dist. cap, and rotor button in it so it should be getting plenty of spark. I can get it started but when its trying to idle it is also trying to die. If i keep giving it gas it will stay running. If i rev it up real high it will idle for a minute and then die. I took the fuel filter off the other day and cleaned it out with carburator cleaner and i noticed what looked to be rust in it but it wasnt clogged up just a little dirty. Im thinkin my gas tank is rusting on the inside but is that possible?

It was running fine for a day now its acting up again and is currently in advanced auto parking lot where i changed the wires, cap and rotor button. On the way there it would run but then when i came to a stop it would die so i had to put it neutral and rev it up till the lights changed. But i made it there changed that stuff and now its crapped out on me again.

I don't know whats causing this but its making me pull my hair out

Suggestions?

Any help is greatly appreciated.

 

Take a can of WD-40 and spray along the Intake manifold, 300-6 was bad for the intake bolts to work loose and blow the intake gasket. This will cause this problem. If this does not help I would check for a stopped up catalytic converter. " If it has One"

 

I would agree that it sounds like a vacuum leak. If the filter is that dirty, I would replace it.

 

I think you've got your main problem identified right there - with a new filter you're OK for a few days until it slowly blocks with rust (maybe water in there too), then back to square one. I would drop out the tank & do whatever you find necessary. A big in-line filter between the tank & pump would help, but if the tank needs work doing to it, best to do it now before you have a major problem - like a leak & fire

 

Oh I forgot to state you need to have the truck running when you spray the WD-40 along the Intake, if it has a blown gasket when the WD-40 hits it it will seal it and the engine will smooth out. If you don't find any thing doing this, If you have an air adjustment screw on the carburetor. Take it all the way out "be careful not to drop it or the spring" and blow Carb cleaner in the hole and then compressed air if it you can. You may have some trash in the idle air circuit in the carburetor.

 

I found my problem. Dead coil. I still may have a vacuum leak I'll check that and post back when I get home. But after work me and a friend went and was messing with it. We took the wire of the coil to the distributor and tried to arc it and it wasn't sparkin at all. So I got another coil for $20 and it's runnin again.

I really do aprreciate your guys help tho. I'm still gonna test it for vacuum leaks and I'm gonna run it a few days and clean the filter out and see how bad it's collectin rust. I just cleaned it last night.

Thanx though you guys rule

 

Just buy a new one. They're cheap, and not really designed to be reused.
