QuestionMy grandmother owns a 93 Eldorado with the 4.9L, unknown as far as past repairs, Problem is that the fuel pump doesn't come on when you try to start it, it was driven to the store, then wouldn't start since.
We've checked all fuses & relays pertaining to, even the hidden ones under the hood, Removed neg. battery cable for 5 min., the fuel pump was removed and tested good, no pressure test, but it won't even come on when installed.
I checked trouble codes and found; S011,S016,S026,S044,S063,P052,P109,I052.
Any help would be of great help.

AnswerP052 = Battery was disconnected at some time in the past.
P109 = same as P052.
I052 = same as P109 and P052.
S011 = Left front solenoid short to ground or open in the ROAD SUSPENSION SYSTEM.
S016 = Right Front solenoid short to ground or open in the ROAD SUSPENSION SYSTEM.
S026 = Right rear solenoid short to ground or open in the ROAD SUSPENSION SYSTEM.
S044 = Lift/Drive signal fault.
S063 = Right rear position sensor fault.
What you need to do is repeat the OFF and WARMER sequence and note that as EACH CODE displays the word CURRENT or HISTORY will display with EACH CODE.
I need to know which codes are CURRENT or HISTORY.
