86 Lincoln: started shutting off and not restarting for several minutes. Someone suggested vapor-lock. Removed gas cap waited ten to twenty mins. Started car. happened several times. Then car began to shut off even at highway speed. Turns over fine. Won't start. Sounds like no fuel to me. Just had fuel pump replaced last year. Fresh ideas welcome.

Did you try disconnecting the battery terminals, negative first, wait 10 min., reconnect negative last, should force the antitheft system to reset.

Sounds like a bad connection on your ignition switch or wiring in the fuel pump circuit.

Night be vapor locked..What's that? It when your gas tank pressure becomes greater than your gas pump...You'll be driving then it just shuts off like running out if gas... Quick fix? Open your gas cap and leave it Lise to get air into your gas tank..Clue if this is the problem...Your car will start immediately. Hints...Listen when you loosen gas cap...Can you hear air sucking back into your gas tank. Cheap fix..Take the smallest drill bit and drill a hole into the center of the gas tank..It also could be a replacement gas cap that someone put on the car..Buy the original cap..What caused the problem to start with? Over filling your gas tankk..Putting that extra 75cent to top it off..Your cars gas tank is designed to burn fumes...When you over fill a tank it sends gasoline down those vapor hoses then into a charcoal canister..Over years if doing this...It gets clogged up then the fumes can't get out the tank...It builds up pressure and becomes greater than your gas pump...Then it shuts off...If you wait long enough....it will start back...This sounds crazy....But this could really be your problem...Next time the car shuts off... loosen gas car...If it starts...BINGO....You have solved your problem... Drill a hole in gas cap or buy another canister... Usually behind the headlights... Some under car..Follow the gas line... Hope this helps you or someone else....Stop over filling your gas tanks...You'll keep this from happening....Tell others

Not real familiar with waverunners (this is a car and truck section after all), but remember that when you have been riding and stop engine it gets much hotter. Could possibly be coil "Heat Soak", or even a fuel system vapor lock issue caused by a pinhole leak in a line or a bad gas cap. Not very confident in this, but the best I got. Try posting in the waverunner section.

Sounds like it could be a bad starter solenoid.

Possibly a vapor lock. Try with the gas cap on loosely. If it runs fine then you need a new vented gas cap.

Vapor lock, from my experience, is a pretty rare problem. Unless you have put too much starting fluid in through the air intake. If you have not tried to use starting fluid, you should try to spray some through the airfilter, or the air intake for the motor, while someone is trying to crank it. Do not over-saturate it, or it will cause vapor lock. (vapor lock is all fuel vapors and no air). I have a suspicion that a few squirts of this will get it to fire up. If it starts but then goes out after the starting fluid is burned up, then you may have a problem with the fuel not getting to the engine.

Just guessing but trying to help...Your car might be vapor locked..Take off your gas cap... Do you heat KT sucking in air as you take it off...If you do your car will now start...A lot of people at the gas pump will try to get that extra fifty cent in their tank at fill ups..Thats the worst thing you can do. What your doing is putting gas down your gas vapor line...Its meant to burn vapors from your gas tank..When you over fill your gas tank this gas runs down that line into a canister that has charcoal as the filter built inside. Over time your gas will harden the filter to where it becomes clogged..Then as the pressure in your gas tank becomes greater than your fuel pump...Your car will shut off not start back up until the pressure in the tank drops....You can replace this canister... Most are behind your headlights on drivers side..Its that little black box your never did anything..On some vans there underneath...Another thing :is as these canister's go bad your putting all that broke down black charcoal right into your carburetor.. That's those lines thats those lines that are hooked to it at the bottom...So your feeding your car junk...Never over fill your car because in time it will shut off...So just loose the cap and lesson for air sucking in....Try to start it with cap off...More unlikely you have a non stock fuel cap..Either drill tiny hole in the center of cap or replacei it with factory stock...Also some cars have a fuel shut off switch that will shut the gas off in crashes...Sometimes these switches will go bad....they can be reset...Might be in truck under matting....Good luck...Hope all of this helps someone

keeping the vehicle running during a fill up is a definite NO NO! there is the increased risk of a fire(very bad) the possibikity of someone stealing your car(bad) and the increase for the problem you are experianceing( not so bad, fixable and preventable). the reason youre having the trouble is youre essentially flooding the engine with raw gas. while the engine is running it creates vaccuum in the evaporative emission system. in a nutshell, its constantly sucking the fumes out of the gas tank and burning them by running it thru the engine, there is a small valve in the tank thats supposed to be exposed to air in the tank, when you fill the tank with the engine running you are drawing this air out while the fuel is being added and you are more than likely sucking the raw fuel into the charcoal canister and its becoming flooded with fuel instead of vapor. after you wait about 10 min this exess fuel has evaporated enough that just the vapor is being drawn into the engine again and allowing it to start. in short dont keep the car running while filling, dont fill past where the hose shuts off the first time, trying to cram an extra half gallon into the tank, and this should no longer be an issue.

vapor locking try losing up the fuel cap
