    If my saw I'd take it to local Stihl shop for pressure tests of fuel system and fuel tank vent. I think you may have leaks in fuel supply system. Lou

It can be a multitude of things. Without knowing what kind of saw it is, I might venture a guess that it might have a buildup of sawdust between the engine case and the fuel tank. This causes it to run MUCH hotter than normal, which causes the gas to get way too hot, making starting very hard. On older Homelite saws, if it isn't kept clean it will acually boil the gas in the fuel tank. Take the starter cover off, and blow it out as good as you can with compressed air, wearing safety glasses.

200e chevy tahoe sputtered shut down while driven on turnpike after getn gas started back up few minutes later thot it was bad gas what else could be problem


It could be the fuel pump. The pump is in the gas tank. The pump is actually cooled by the fuel. Occasionally, in hot weather, when the pump starts to get old, if you run the fuel tank very low, the pump will heat up. Then, when refueling, you are putting fuel in the vehicle that comes from underground at about 50 degrees F. This can cause the pump to fail.

They put gas in my trimmer instead of the fuel oil mix snf now it will not start. what must i do??


Drain tank completely, pump primer to drain that back into the tank, empty tank again. Refuel with correct fuel oil mix 50:1. Hopefully if it wasn't run too much, it might not have dameged the cylinder and piston. keep your fingers crossed

My 1996 chevy truck want stay runing,when i push the excelerator it die i change the fuel relay,i reset the distribution timing. please help


You may have the same problem my Wifes car has right now- ice in the fuel line.

Dump a can of DryGas (or "Heet") in the tank, and after about an hour, start your truck. Let it run for 15 minutes or so (restart if it stalls) - if it will not run that long try moving your truck into a warm garage, let it sit for about an hour, and try again.

The DryGas does not perform miracles, and takes time, especially in the bitter cold as of late.

Fuel line icing is usually caused by allowing your vehicle to run nearly empty, and then refueling in cold weather. This causes condensation in the gas tank, which freezes in the gas lines.

I have repeated this mantra to my Wife for nearly our entire 27 years of marraige, but she still will run her tank nearly dry before getting gas, even though it has so far cost us two replacement gas tanks, more than a couple gas tank leak patches (the other problem with running low all the time is rotting out your tank!), and uncounted winter car starting problems. Please help me break the trend!

Starts only when it cold and does not start whwen hot


just off the top of my head. it may be the fuel pump relay, when its cold it is ok. but when hot it will not work. check it out. hope this helps. have a good day. if when hot. see if fuel pump is running, just get under car at tank in back. and have a person turn the key to on, while you put hand on tank to feel vibration. if pump works its not the relay. if it does not when hot,it is the relay! a fuel pump only turns on a few seconds to get fuel to engine, then when running it is on all the time.

2001 GMC Jimmy is Hard to start after refueling only. Runs great after finally starting until next refuel. Tried new fuel cap but engine light comes on and shows P1441 on code reader. Says it could be Evap...


Try filling up a little less. To me it sounds like a vapor lock issue which clears after you burn off the top bit of gas.. Next time you need fuel up be sure to keep track of how much you put in. Another idea is to run the tank down and then only fill up to half a tank. If the problem clears then you know that you're having a vapor issue probably due to gas saturation of the canister (which can happen if you overfill the tank).

Difficult starting when hot. When first


First suspect is the fuel filter which is combined with the tank fuel connection. Remove the rear engine housing to access the tank. To access the carburetor, the front housing must be removed. The worst part of this is disconnecting and reconnecting the throttle wire from the carburetor. You might try running some fuel system cleaner through before going through this procedure. Good luck!

Starts ok when cold. acts like it's out of fuel when hot.


Clean or change the sparkplug. Also make sure you have fresh gas and the proper fuel mix.

Audi 80e 1991 hard starting when cold


I've owned the same car. Check that the fuel relay 'primes' the system before you start the car. When you turn the key to the on position (all you dash lights, ready to start) you should hear the fuel pump run for a second or two. If it doesn't run you can replace the relay for about $30. If the relay is not the problem, it may be a check valve within the fuel line to the engine. This valve keeps fuel from draining back to the tank when the car is sitting. That way, there is fuel close to the motor when it's time to start. The temp senor was not a bad shot, they were thinking it was bad sensor not telling the cold start injector to run. Obviously not the case. However, the injector itself may be faulty in some way. As long as the car always starts, it's one of these problems, assuming the ignition system and engine mechanicals are in running order.  good luck. JK
