ignition problem ?? with 93 suburban 5.7
93 suburban 1500 4x4 with 5.7 automatic 130K miles
ran fine
had a leak in gas tank
changed gas tank and fuel pump and fuel lines
truck runs rich like its igniting about 30% of the fuel
changed plugs--wires--cap--rotor--
still not running right (narely runs)
put obd 1 on it ---shows code 54 (fuel pump relay failure)
changed fuel pump relay ---still runs like crap
again...its seems like all the fuel isnt getting lit but then again it ran ok before we changed the tank ..maybe fuel is ok and its a coincidental spark problem
anyone have any ideas ??
Thanks AL
