Customer Question

I have a 1998 Lexus GS300. It starts the stalls. I've sprayed starter fluid in the throttle body, I runs until the fluid burns off. There are no codes. I replaced the entire fuel pump and regulator. What am I missing?
JA: Is the check engine light on? Does the car stall at idle or when driving?
Customer: Idle
JA: Are you fixing your GS300 yourself? What have you tried so far?
Customer: I've installed new spark plugs, fuel filter, fuel pump, fuel regulator, EFi relay. I've test for power from the fuel pump ecu to the pump. Switched fuel ecu's still nothing
JA: Anything else you want the mechanic to know before I connect you?
Customer: That's it
