1991 Mitsubishi Mighty Max 2D 4X4 V6-(FUEL INJECTED) Hi, My truck acts like its starting but it wont start. Its getting gas (i know this because i took off the fuel pump hose off the motor and it is spraying) So the pump is working (but i dont know if its pumping enough) I also put gas in the air filter hose it did pop! Now im going to try replaceing the fuel filter, if that doesent work i will check the injectors. then a fuel pump if needed. I understand that this truck needs fuel pressure so i dont know if its getting enough pressure. Please help! Thanks!

i can hear the injectors when i turn the battery on but it seams like they are erratic some go off at times then start clicking again. When i put fuel down the air intake it almost started, it popped ran for about 5 seconds and quit. I took the fuel line off the engine and fuel was pumping out but i could put my finger over the tube and stop the fuel. So im guessing that there is not enough fuel pressure. I replaced the fuel filter. Filled the tank. Still no start. So now im thinking about dropping the tank and replacing the fuel pump sense that creates the fuel pressure. So my question now is do i replace the fuel pump or the ECU?
