To expand. Not my car. Got a call from a relative to help out, curbside.. The car stalled after a normal 70 mile drive with no hint of trouble. It will only idle, barely. When cool it will rev a bit but sputter. It idles poorly, with stalls.
I was told the trouble code light was not on, Only later I found out it didn't show at all. Perhaps a burned out bulb but anyway I didn't scan it then. Thought it was fuel supply so changed the filter No fix.. The pump was delivering but couldn't be sure of pressure, curbside, so replaced the pump. No change. I did pinch off the fuel return line to make sure it was not a pressure drop problem. It wasn't
Towed to my garage. Thought maybe the timing belt had slipped, No, Then checked the TPS, good. Then found out about the dead code light so did the scan.
Will work on it tomorrow but the codes are rather obtuse, to me. I know what the sensors are but the high voltage and circuit failure messages are not clear to me.
I wonder if it may be an ECU failure.
Any input appreciated.
