Turns over fine, just will not start. Replaced both spark plugs. Removed and blew air through fuel filter. Doesn't seem to be clogged. Does anyone know how to tell if fuel pump is bad or what problem might be? Thanks!
Still ,lets get back to the basic problem of a engine that want start.... JF it is turning over by the power of the starter and a charged battery......(1) Is it a 2 or a 4 stroke engine? (2) Remove the plug or plugs and preform a compression check,,,,(Always,,,, start here ,,,,,,, no exceptions,,,,,,, (2) See if you have spark at the plug or plugs,,,,(spark should jump a 1/4 gap ),,,, on most 2 &4 stroke engines,,,, Refer to manual on your motor,,,,,, (3) Next see if you have gas to the engine,,,,,, If you have all three ,,,,The engine should (hit),,,, BUT not necessarily,,,,,,START..... This is where you will have to bring a manual into the problem to see if the engine is receiving the correct amounts of the basic three, above,,Very simple test to tell if the fuel pump is bad. Disconnect the fuel line at the carburetor and put a container under it. Turn the engine over and see if you have fuel flow coming out of this fuel line. Its just a low pressure pump but you should have a stream of fuel.

Well, to test fuel pump properly you should do it with engine running. Obviously your engine ain't starting but try this: disconnect fuel line from the pump leading to carburator. Fill that line and the carb with fresh fuel. I use squeeze bottle with a plastic nozzle. Hold that line in upright position and give it a crank. If engine fires up you're golden and you can turn it off as soon as possible. In order to test fuel pump you must run the engine at fast idle for 15 sec. If you have pressure gauge should read about a 1 psi, if you don't have a gauge you can do volume check. Fast idle for 15 sec and you should have about 3 oz. in the bottle coming out of that pump.
