Where is the voltage regulator located on 92 chevy lumina euro

Fuel Shutoff Valve according to all the articles, however the switch operates the valve and the valve tells tales back to the ECM. You would need a pro grade scan tool computer to diagnose against known voltage values.

You may want to check the starter unit of this car and make sure its working properly and if possibble try replacing it so we can isolate if that is the problem....

Hope that helps.........

the voltage from the big red wire is battery power
the smaller wire will not have voltage until the alternator is running
one wire goes to the charge light to the voltage regulator
check that the voltage regulator is operational
better still get an accredited auto electrician to check the charge circuit , voltage regulator and alternator for operation

the voltage regulator is built into the alternator,have you check the alternator connector for damage or corrosion check with a test light for voltage at the red wire that plugs into the alternator that is in the 2 wire plug connector as well as check the large red wire for voltage as this wire is the feed wire from the battery.you don`t say if this is a new or used alternator.if you have a voltmeter that is the best way to check for the proper amount of voltage at the test sites.the battery must have a minimum of 12.6 volts to start with higher is better.to test the voltage regulator need the engine running and you need a voltmeter to tell properly if it is working.at the back of the alternator their is a hole that looks like the letter D this is where you use something like a cotterpin and insert it into the hole you should feel a tab,push lightly on the tab and ground the cotterpin to the side of the alternator using the voltmeter you should see the voltage start to rise and hear it start to charge.the battery voltage and the feed wire at the alternator as well as the smaller red wire at the plug connector should be the same.charging voltage should be about 14.5 volts.

This is a long shot, but I had a similar problem and it ended up being the that water pump locked up and caused it to jump time. Adjust timing and give her a crank.

On the accumulator. Under the air filter box.

If you havent replaced the battery I would start there. If the battery has a dead cell in it then it will effectively remove the charge that your alternator is putting out causing your vehicle to stop running because it has no power. I would jump start the car without the battery hook up and remove the cables and see if it runs that way. If it does you have a bad battery.

Had fule pump and filter replaced, 3 months later, same problem, car will not start, replaced Relay Switch, still wont work. any suggestions?

No, cehcek that the terminals aren't corroided.
Maybe even remove them and clean them up.
Then try jump start.

Did you wire in the Cummings PCM ?
