Got a 93 lx 5.0 with a 255 liter in tank fuel pump. it just shut off one day while it was idling and for a while after it would either not come on, come on and keep running or on occasion prime and start. but it would only run between a few seconds and 10 or 15min and then shut off again. i have replaced the fuel pump relay and the fuel pump with a highflow fuelsystems 255 liter in tank. and here lately its only gotten worse. its only started once since for like 5 sec and now i the fuel pump not even coming on any more. I need help bad!

First thing you need to do is find out exactly what's going on with the circuit. Rule out a bad pump... check for battery voltage at pump with key on. Is fuel pump fed through a fuse or circuit breaker?

First can you run the pump from the ALDL connector??? If not you have an issue with the relay or the pump. Try doing this and post back with the results. :bigthumbsup:bigthumbsup
