Question about Cars & Trucks
Car runs about one minute then dies. Already changed air filter, plugs, cap, rotor, maf, vacuum line, air pump relay, fuel filter
Try running the fault codes to find the fault rather than guessing and wasting money. After all the CPU stores the faults in a memory waiting for them to be read and fixed.

I Would Suggest That You Complete A Engine Cylinder Leak Down Test.....(not A Compression Test But A Leak Down Test) this will tell you if you have internal problems....possible worn rings or a burnt valve(s) I would use a smoke machine to check for vacuum leaks also. Good Luck

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

Check throttle position sensor (TPS) is a sensor used to monitor the position of the throttle. The sensor is usually a potentiometer, and therefore provides a variable resistance dependent upon the position of the valve. The sensor signal is used by the engine control unit (ECU) as an input to its control system. The ignition timing and fuel injection timing (and potentially other parameters) are altered depending upon the position of the throttle, and also depending on the rate of change of that position. For example, in fuel injected engines, in order to avoid stalling, extra fuel may be injected if the throttle is opened rapidly (mimicking the accelerator pump of carburetor systems). the cost about 50-75 bucks.
