What's up everyone, I am a newbie. I bought my 1992 Sc400 not to long ago with 210,000 miles. The car is in great shape. Immediately after buying I did a complete tune up (plugs/wires/coils/fuel filter/air filter). After about a week I noticed at stop lights the car would stall but would start if I kept my foot on the gas. I searched the forum and narrowed the problem down to a bad fuel pump ecu so I by passed it n car ran fine for 400 miles but the other day on the way to work the car stalled out as I was getting off the highway. The car again started when given gas but as soon as I let off the pedal no matter at what speed the engine died out. Got to work turned the car off and back on 5 min later and car has ran fine ever since!!! Anyone ever have this happen before? Thanks for the help

 

So your saying the Car has no more problems at all right? After you by passed the Bad fuel pump ecu...?

 

yes the car ran fine after i bypassed the fuel pump ecu
runs fine now as well
