Ok I have experienced the common #303 relay burn out in the fuse box. The story goes like this... Car intermittently quit and would restart then one day it just quit. I being the manly man I am (without research) decided that the fuel pump had gone out. New pump installed and still nothing. Watched YouTube then found a burned out #303 relay (soldered one). Next I changed the fuse box. The car will now crank and die after a few seconds. I can give it gas and it will go but it's very rough and will not idle. I thought maybe humidity in the lines. I added a bottle of heat and it made no difference. I have no Check engine light but I do get a Check Charging System. I have also cleaned the MAF, sprayed the vacuum line with carb cleaner and changed battery posts. If y'all have any ideas please help me!!!!!
