I have the same problem with one little difference. When i turn the key it beeps and goes through all the lights. has been a little hard to start but not bad. After i start it the check engine light comes on and the alarm sounds for about 10 seconds then alarm stops but check engine light stays on till get on plane. It only does it when at low rpm and comes on and off for different lengths of time. Im guessing its the same as everyone else start checking the fuel lines. Any other ideas?
