92 Lexus SC400 no start
The car ran great then the next day, no start but ccranks ok. It has spark and fuel almost seems like too much fuel. I can get rpm reference with my snap-on scanner, so i think the crank sensor is ok, plus no codes. The injector pulse is 17.0 m/s when key is on and 19.6 when cranked. That seems way too high, like maybe the quad driver in the ecu is bad. Any suggestions? Thanks guys.
Can't really help, but I'm subscribing since it would be interesting to know what it turns out being.
How are the injectors driven on the 400's? Only on the driver in the ECU?
Do update the thread when you figure it out.
