Last week I took my see out around the neighborhood to test the brakes.(I just replaced the entire system) While out the battery tipped in it's tray and grounded against the valve cover. Now if I try to start it, it will start if it has been sitting for awhile and revs as long as I give it gas. Once my foot comes off the accelerator the engine fades and cuts off. Once it cuts off I might be able to start it once more but after that it won't start. Everything seems to be cranking but the gas just won't come by it self. The fuel pump is also only two years old. I would appreciate any suggestions or help. Thanks.
