Nole65SG Posted September 3, 2004 Share Posted September 3, 2004 My 1992 SC300 has a warm start problem. The car will start up and then after about 3-5 seconds dies out. The problem will keep repeating itself until 7 or 8 start attempts when the RPMs will finally remain steady and the car will not die. Does not happen on cold starts or while driving. Only after it has rested and while the engine is still warm. Mechanic started off replacing the fuel filter and then replaced the fuel pump. Said the old pump was only delivering about 7-8 psi. Drove the car home and problem again is repeating itself this evening. Taking it back in the morning. Thinking could be another problem or a bad new fuel pump. Any thoughts or similar experiences? Thanks! Quote Link to comment Share on other sites More sharing options...
Nole65SG Posted September 3, 2004 Author Share Posted September 3, 2004 Research this forum seems to indicate either an Idle Air Control Valve or a Fuel Pump ECU problem. All of this assuming, of course, that a bad fuel pump replacement is not the problem. Quote Link to comment Share on other sites More sharing options...
AWJ Posted September 4, 2004 Share Posted September 4, 2004 Fuel pump ecu. Good luck. Try the 12v test. It should be linked in one of the old fuel pump ecu threads. Quote Link to comment Share on other sites More sharing options...
Nole65SG Posted September 5, 2004 Author Share Posted September 5, 2004 It appears indeed to have been the fuel pump ecu. No more stalling. Thanks. Quote Link to comment Share on other sites More sharing options...
lexcalibur300 Posted September 8, 2004 Share Posted September 8, 2004 From one "Nole" to another: Nothing quite as classy as a "Nolex" in Tallahassee. Who repairs your Lexus in Tallahassee or did you fix the ecu yourself? Thx... Quote Link to comment Share on other sites More sharing options...
Nole65SG Posted September 9, 2004 Author Share Posted September 9, 2004 As I understand, the closest Lexus dealer is hours away in Jacksonville. I worked together with the guys at Action Auto (focus on imports) on Gaines Street to come up with the solution. The info. I received on this board made the difference. Also, keep in mind Bill Cayson off of South Monroe Street. Even though his specialty is Chevys, he has been around. Knows cars well and is reasonable. I have him doing some work on the car as we speak. GO NOLES!!!! Quote Link to comment Share on other sites More sharing options...
