Well I always found that the simplest answer is usually the correct one, So if your car has pressure at the pump and when it sits or has fuel manually sent into it , it starts up , it can only be one of three things, 1. It can be a clogged fuel filter but it would have to be the worst I ever heard of the cause the car wont even start. 2. a Clog in a fuel line or rail . 3. Your injector's went bad (in which case you should buy a injecter cleaner the aerasol can that connect's to your rail and spray's the cleaner right in the injector's. Also you really need to invest the $20 into the fuel gauge it will be a big helps in finding the problem. GOOD LUCK
