Put 5 gallans in the one tank and cranked it a few times. Didn't get anything back up to the filter by the carb. What the heck am i missing???

thanks mike
 
is it a gas motor? If so dump some gas down the carb from a can (soda can). Then try starting it. That is what I do when I run my Jeep out of gas. Don't dump a whole can but just a couple ounces then try to start it. It will probably fire up then keep the throttle open some so the engine idles high and gets the fuel pump pumping again.

His bio says an 84 so that should be a carb with a mech fuel pump. If it is injected then spray some starting fluid down the throttle bores to help kick it over.

It's possible (if after priming it that it still won't pull fuel up) that some sediment or something in the tank got in the line or clogged up the pick up. If so, you can blow back through the line with air.

OR... in an even more rare case, you may not have ran out of gas, but your fuel pump could have just gone out. It's happened to me before.
 
I will give it a try. Its not the truck in my bio. It is a 1980 3/4 ton 4x4 with a 350.

thanks mike
 
If after all those checks it doesn't start try checking the little fuel filter in the line up by the carb (it would be right where the line bolts to the carb big nut looking thing with a cone screen filter in it) if it has one I had a piece of silicone from somewhere stuck in mine and a buddy found it after I gave up.
 
OK did it all. nothing worked. I put 100psi in the line and still did not work. Anyother ideas?

Not tryin to be a smart arse.. But you said you put it in one tank.. So I am assuming it is a dual tank truck.. Do you have the switch on the right tank..???

Maybe that's his problem, he put gas in the LEFT tank but has the switch on the RIGHT TANK. /forums/images/graemlins/histerical.gif

Anyhow, yes as Dan said, make sure you have the switch going to the correct tank that you put fuel into. /forums/images/graemlins/thumb.gif
 
i was told on the older switches, that if you run out, it won't switch tanks. not sure how true it is. my 83 switched tanks even when empty. /forums/images/graemlins/dunno.gif

try puting gas in both tanks and try it.
 
I just put an engine in my '79 blazer and I couldn't get fuel to the carb. I blew air thru my lines, changed my fuel pump and still nothing. I just put 15 gallons of fuel in the tank so I had fuel. Then I figured it out today, if you have duel tanks make sure your switch is on the correct tank and take the fuel line off the trottle body, take an air hose put the blower nozzle on it wrap a clean rag around it to make it air tight then blow air into the tank, make sure someone is watching the fuel line to tell you if fuel is coming out then stop the air,put the line back on and try to start it. It worked for me.
 
our old dually chevy had a fuel pump problem in one tank(88' tbi). it would go out once and awhile, but then work later on.

once we thought it was broken, couldnt get it to fire. then someone noticed the rocker switch had been kicked and it was stuck in the middle . try flipping the switch back and forth.
