Its in the fuse panel under the hood, the panel has 2 screws holding it down. The diagramn is under the cover. If that dosent do it I had to replace the main ECU and the fuel pump.

The fuel ECU can (and SHOULD) be bypassed. You can use a 12v switched and a basic SPDT relay to power it directly off the battery.

It's much easier to troubleshoot than the headache the fuel ECU puts you through.

He seems to be asking about the relay first, but I through in the other for good measure.

most likely the pump is going out. when u turn the car on not start but to the on position can u hear the fuel pump turning on. I think you can get access to the fuel pump under the rear seat cushion. if you can get to the electrical connector and check for power and ground there. its a new pump for you my friend.

thank you very much for your answers, solve achieved by changing the ECU relay works perfect "for now". I have another question, my SC300 is 96 and does not have the traction control button, remove the console and saw two connectors coming from behind to come Differential my question is can apply this model traction control? thx
