1- "search" is your friend
2- take your gas filler cap off, while the engine is running shine a
flashlight into the hole and see if there is any bubbling or
misting while you are having the problem. If there is you have a
leak in the gas line from the pump to the injectors
3- check your grounds - there are 3 of them
4- be patient and persistant, intermittant problems are a PITA
