ok, let me start by saying the Cobra always takes 2 times to start. The first time, it starts then dies withing 5 seconds. The 2nd time it usually stays running and warms up. Today, 30 degrees, I go out to start it and it dies the 1st time, no biggie, then it wont start period. It just turns over. Plenty of gas, I can hear the fuel pump kick on, etc. It turns over fine, just wont start. Any suggestions?
