ok so what i did today i looked in FSM for my 89' an i seen on pg EF & EC 120 & 121 the trouble diagnoses for the fuel pump. The way im understanding this is to
disco the fuel pump harness and check voltage between terminal A and ground. Voltage should appear for 5 secs after switch is turned on. if not good check power supply from relay side. MINE WAS BAD
If thats not good to disco the fuel pump relay and check voltage between terminals 2,4 and ground if good check the relay for continuity (ref. EF & EC-150) MINE WAS GOOD
Check continuity between relay harness connector terminal 1 and fuel pump harness connector terminal A. MINE WAS BAD it says to repair or replace harness or connectors between terminals 1 and A
my question now is how an i suppose to do that basically the "easiest" way or "smart" way other than cutting open the whole harness and seeing if i have a short in the wire somewhere? Another thing that should be noted is that my brake lights are on at all times!? Whats left to check? the ECU? if so which pin is the fuel pump? i have the 62.
