Ok heres the deal the truck is a 72. the timing is on perfectly i have checked it several times. it has plenty of spark and it is getting fuel but it still wont start. when i try to crank it over it will putter and die shortly after when i give it more gas it wont even start what the hell is wrong with this thing... oh btw i have tryed starting fliud its just the same outcome still wants to start and runs for a couple seconds before dieing.
