Bypass The Fuel Pump and Check Then...Might Be A Choor Switch Is Not Providing The Needed AMPS To Fuel PUMP>>.!
F.P Takes Almost 7-9A To Operate Correctly.....!
sometimes its a grounding problem of the fuel pump that can cause it to run slow and even burn out due to this.
Make sure that all wiring is soldered and test the loads with some sort of ammeter to confirm.
Recently bought a GA15DE engine for my Nissan B12, I am not sure if the Shershah guy has given me the correct ECU or the complete uncut harness. Can someone guide me to a good mechanic, I heard Poona Motors is a good choice. Thoughts anyone.
