Cummins not starting?
New to the forum here, but I've been a religious reader these last couple weeks scouring the posts for solutions. I've got an 03 Ram 2500. Just put in a 6 pack of reman injectors (installed by a cummins mechanic). The truck ran great for about four days, although I noticed it was starting to hard start and worsened each time I fired it up until it just didn't fire without starting fluid. I read a ton of posts about the pressure relief valve, tubes not being torqued correctly, lift pump, lines not tightened etc. and they were all great places to look for troubleshooting a hard start. The one thing on all the diesel forums that I did NOT find however, was the FCA (fuel control actuator) being the cause of a no start. My mechanic and I troubleshot the CP3, lift pump, injector return, pump low psi return, pressure relief valve and FCA. The FCA did test bad on the fluid volume test, but I couldnt find any threads about this being the cause of a non-starting engine. I swapped the FCA with a buddys truck that was the same year and the truck fired with one crank. Got the new part on the way today for $110 from Cummins. SOOO, I just figured I would make a thread and throw it out there that the fuel control actuator CAN be the cause of a 5.9 not starting and definitely the cause of increased hard starting. Love all the threads, help and info you guys have given on this site! Keep rollin coal fellas
