Using a compression tester, do a normal compression test. Next, add some oil to the cylinder and do another compression test. If the second test reads higher that the first test, there is some blowby going on. The oil acts as a seal around the rings and helps improve compression. Another way to check it is with a leakdown compression tester. RRGrassi--1990 D250 5.9 Cummins Getrag 5 speed '91 Mercedes 300D '06 VW Jetta BRM TDI 1.9 5 speed Early 80's Hinomoto E230 Diesel Tractor 12 speed. .

However, Cummins had to modernize the engine and add newer technology to keep up with the diesel power race of the 90’s, bringing the new 24v common rail engine. The switch from a 12v to 24v and to common rail fueling lead to a number of problems with the fueling system on the 5.9 Cummins 24v engine. Generally, this issue is more prevalent in engines with higher mileage. A cold engine compression test on your Cummins diesel engine can identify it as the source of the problem. Low fuel pressure: Most fuel supply issues originate from insufficient pressure. The best way to identify if this is the problem is to make sure the tank has enough fuel.
A failing 5.9 Cummins turbo can cause rough idle, which means the engine is not running smoothly when the vehicle is at a stop or idling. This roughness can be caused by several factors, including a damaged or worn turbocharger, faulty injectors, or issues with the fuel system.

ok first check the solenoids for resistance. sooter you do not say if you have a 04 or a 04.5 so i give both. on the 04 there are three injector plugs, one for each two injectors. it is a square plug located on driver side high up near the valve cover. remove the plug and check each 2 injector wires for resistance. you should read about 0.4 or .
