yes i have a 1991 nissan 240 sx,the engine will crank over but wont run,i checked the fuses,ignition coil,alternator and battery all are good i put in a new fuel pump and o2 sensor it still wont run,whats wrong with my car?
without further information it could be a number of things. bad timing would allow it to crank but not run, just like misplaced spark plug wires. you said you replaced the fuel pump, could it be you don't have enough ( if any ) fuel pressure. how does it crank, if its sluggish then your battery isn't powerful enough. like i said without more info it could be anything. i'm just waving my stick
