Does it have a fuel filter, or air? If it does make sure they are both clean and free of debris as priming will force fuel up line but will die as soon as its burned out

My mtd mower with 15.5 hp engine starts and runs for 5 to 10 minutes and quits. It will usually restart with the choke on and run for a few minutes more and quit again. It will finally not restart.

More than likely a carb problem. What kind of fuel you use makes a difference. If ethanol, causes corrosion inside carb. Or maybe something easy as air filter.

The saw has good compression! ive done everything i related to running and still cant get it to start im stumoed any suggestions?

For all small engines, check for spark (pull the plug, ground the plug's metal body to metal engine block, pull cord and look for spark in the gap). If you have spark, prime the head with about 1 teaspoon of gasoline or a squirt of starter fluid through plug hole, replace plug and try again. If it runs for a few seconds and quits after several attempts at priming, your carburetor needs cleaning. Probably gummed up with old gas (not drained)... a sticky situation. Remove, dismantle and clean with carburetor cleaner or replace. Next time, empty gas and run it dry.

Well if it is a gas engine truck the most likely cause is a bad fuel pump. If it will not start now, turn the switch on and listen to hear the fuel pump. It should make a faint hum noise for about 3 seconds after the switch is turned on, it will only run for a few seconds to prime the system. If you have someone to help you, you could put your ear to the fuel fill with the
cap off and have someone turn it on. If you cannon hear the pump have
someone attempt to start the truck while you beat on the bottom of the gas
tank with a rubber mallot, it the truck starts, sputters, to you hear the pump come on while beating then you have a bad pump. This may sound like a wierd test but mechanics do this all the time to check a pump.

1992 cadillac deville ....parked it at night and in the morning battery was dead and car wouldnt start. Charged the battery and now it cranks but will not start. if you let it sit for a minute and then try...

does it have three second fuel pump run when you turn key to run position/ in between you should let i rest 5 or so seconds then try it again also some of these cadilacs have oil pressure sending unit wich takes the duty of keeping fuel pressure up is fuel pressure lowering as engine quits eg. rev up some in your few seconds of running while the engine is quit momentum keeps it turning for a short time see if you r pressure maintain thru the wind down

Quit running while driving. Will start but only idles for a few seconds

You'll have to adjust the Idle so that the car will not quit running while driving .because less gas is entering to the engine.after you adjust the Idle then the car can run and not quitting.
