Ran out of gas. got gas, splashed a little gas in the carb? (air inductor) looks like a carb under the doghouse. now, won't start, wants to but won't keep running. 1994 dodge primetime van.

If your fuel pump is in the gas tank the fuel pump is cooled and lubricated by the gas. If you run out of gas and keep trying to start it many times you can damage the fuel pump. If you have a older car you can try putting a little gas in the carburetor and see if it cranks, if it cranks with gas in carburetor you know it is a lack of fuel problem. You might try spraying starting fluid in air filter but to much can damage your engine. Some links below may provide some help.

Your vehicle fuel pump can run and pump gas but depending on your vehicle you may not have enough fuel pressure to run. I would check your fuel pump fuse and relay and fuel inertia switch/fuel pump kill switch if you have one. I do not know why running out of gas would cause them to fail but it is something to check.

Take the air cleaner off an pour a very little bit of gas into the carb and it will help prime the system and get the gas pumping again.

many of them fords get vapor locked,,, you might have to pull the tubing off the air filter , and on the carb / throttle body side. put a ( little ) bit of gas in there... being VERY careful not to over do it ....

trace your fuel line from your carb back to fuel tank, sounds like you have a severed fuel line. in either primary or return. it will start on starting fluid but won't continue to run without fuel.

you probably have air in the lines, if you have a carb, spray some quick start into the carb and turn it over, if it starts and then dies when the starting fluid has run out, you probably need a fuel pump, since the running of the car should have blown out any air that was in the line, If your car is fuel injected, loosen the bolt cap at the end of the injector line that supplies the fuel,, and tap the key once,, ( don't start it,, ) just turn the key on and off 3 or 4 times, this should blow fuel out of that loose bolt head, if it does your getting fuel, if not, back to the fuel pump, also you can check this link, http://www.aa1car.com/library/us1296.htm

When it ran out of fuel there may have been damage to the fuel lines. I would suggest getting it looked at by a mechanic to be safe

take the air breather off and put a little gas in the carburetor but not to much the carb can back fire let it set for a couple of mins. then try starting it,when it starts it going to sound a little rough till u put the breather back on then it should calm down

black soot is a running rich condition it's getting to much gas not enough air .. 14-1 ratio air to gas your carb rebuild needs to be rechecked for sticking float..

With a new plug and fresh gas it should start. Check to make sure there isn't a kill switch turned off or that the gas petcock from the tank to the carb is on.

How did you check the fuel filter? Disconnecting it from the fuel line that goes to the carb is the best way, making sure the gas is turned on under the tank. Bleed off a little gas into a can or something just to make sure the filter isn't plugged.

The last thing I'd do is take off the air filter and spray a little starting fluid in the carb. It may start and run several times if there is old gas in there somewhere. Remember the bowl on the carb is probably still full of old gas. After some fresh fuel reaches the plug it should start and continue to run.

(You might drain the bowl on the carb of ols gas before you go any further)

Good luck!

you have goten air in the fuel system. you need a friend to help out with this. but if you open the hood and look on the intake the fuel rail. you should see some thing that looks just like a tire stem cap remove this cap and make sure you have safty glasses turn the key to one and then push the little plunger down under that cap. you will have to do this until a nice stream of fuel comes out with out the air. now be carefull and remember this is a pressurized fuel line so were safty glasses
