SOURCE: error code 51 (injector circuit) on 1994 nissan se v6 pickup

I would start by checking the resistance of all of the injectors. I saw this happen last week, I had a new injector that was reading low ohms and it was making two cylinders misfire. Replace the new one with a another new one and both cylinder ran good. I dont know what the ohm value of your injectors should be but I would want at least 10 ohms, All of them will be about the same except the bad one..I did a web search on your problem and it was covered at several places.

The cylinders are numbered as on the spark pack you changed. You might have done better putting the seafoam in the tank as an injector cleaner. Not sure why you changed so many parts, you seem to know how to get the codes from test connector lead hookup and the blink pattern. You might also want to check the fuel rail pressure and the crank and cam angle sensors. Before replacing the injector, swap the #4 injector with the adjacent one and see it the code moves with the injector or stays put. If the code stays on #4, then check the injector wiring, if it moves clean or replace the injector.

Check the connections under the FICM. (fuel injection control module) It is on top of the left valve cover. It is the big silver flat box. There is 3 connectors underneath that should be "clicked" onto the module. Do this with the key off as there is a very high voltage there.

Renault kangoo 03 1.5 diesal throwing lots of black smoke out

Burning to much fuel. You can do a cylinder contribution test(takes a scanner) And see which cylinder/s are lagging. Then go after the injectors. One or more could be stuck open, pouring fuel into the cylinder.

It looses power when going up hills and produces alot of smoke.

Hard to say, and there doesn't seem to be any indication of rain coming soon. But fire crews are working on the issue.----------------------------------------------------------------------------

Using oil with no visible leaks. No water in oil or oil in water and not down on power so head gasket should be ok. Not blowing smoke when hot or cold. Alot of oil blows out oil cap hole when cap is...

It sounds to me like the oil is being used slowly, by running through your "valve stem seals". The Valve stem seals are small pieces of rubber that surround the valve under the valve spring. They are designed to keep oil from running down the valve, and into the cylinder. When the valve stem seals wear out, they allow oil in small amounts to pass through the cylinder head, and run into the cylinder. If the vehicle sits for several hours, you will usually see a small amount of smoke on start-up, but rarely will ever see smoke while it's running.
