I rebuilt the engine on this quad. Someone ran it out of oil. So ,new crank, rod, piston.....etc. I got it back together and it starts up, idles high for 4-6 seconds, then dies. Repeat. I set the TPS per the manual. I didn't have the right fitting to test the fuel pump like the manual describes. But, I did undo the fuel line at the tank, and hooked up the pressure gauge. When I hit the key, the pressure goes up to about 45 like it should, but, then drops right off. I put new pump on it yesterday, and it does the same. WHere to next???
