I have a running Engine!! I got it reassembled enough to get it to run. After bleeding the lines, it fire right up after a couple second of cranking. It put out a big puff of black smoke and immediately started idling with no black smoke it is running nicely. Only ran it 30 second since I have...

Well is it fixed!!! The Stop/Start level was assemble incorrectly, the shaft was binding on the bushing, there was some corrosion on the shaft. Clean it all up and it rotated freely. I was able to figure out where the end of the spring should be located, see picture. The real challenge was...

I disassembled the gear cover and found a few interesting things. First there was RTV all over the springs. see picture. Not sure if was the total source of the problem. I have confirmed the fuel rack does now move on its own the spring has enough force to move it back with the injector pumps...

Thanks for the advise, I was planning on doing that since it is not going to be easy to see what is going on inside with the radiator in place. Fortunately I had not put fluid into the radiator since it was drained as part of the sale. I decide to hold off with putting in Antifreeze until I was...

@Ray70 , Thanks for confirming that is what thought, and I just wanted to make sure I did not miss something or assume the wrong thing. Based on that, the engine is not going to start without addressing the issue of the fuel adjustment rod moving on its own. I will have to open the front up and...

Sorry it been a while, have been traveling and have not had time to work on the unit. I started to reassembling the motor after removing the injector pumps. I wanted to see if I can at least get it running before trying to address the issues with the stop/start level and disassembling the front...

I do have general question, as I stated in a my other thread, I have limited experience with Diesel Engines, done plenty of work on gas engines. When I tried starting the engine and before knowing there was an issue with the metering pumps not being installed properly and then the lever issue...

Thank you for all the advise? I am ordering the parts since I am not sure what will be needed and just better to use new when I can. Okay, righty loose on the bolt, I was about to read the service manual to see if anything I should be aware of.

First, Sorry for any confusion between my two different posts I have made. Yes same generator two different issues, Original issue is fixed all electrical as far as I can tell. I spent some time on the unit this weekend. I was originally trying to avoid opening the engine up hoping for a simple...

I did confirm all the meter pumps fuel adjustment pins moves freely on all 4, as I said they are all new, there is no signs of any wear on the bottom which engages the cam shaft. When all the meter pumps are removed the fuel adjustment rack does move freely, but it does not spring to the...

I have been working on a MEP-803a I bought from auction that had a number of issues. Most of them were electrical, broken or missing parts. All those have been addressed and still can not get it started. The Metering Pumps were replaced and installed incorrect, I have fixed that. The front gear...

@Ray70, as you pointed out the fuel stop/start lever did not look like may others I have see. My unit is a 2010 model and it appears that newer units have a similar lever. I know the metering pumps were replaced, not original no green paint on them and they appear to have a date code of 2023 on...

The spring on the solenoid is in working order, I checked at all ready. I found this https://www.steelsoldiers.com/threads/mep-803a-governor-question.223729/ this could be it since I found one of the gaskets for the metering pumps in the bottom of the unit, but I could not find which one it...

Yes the knob moves freely in the slot. What I figured out when the solenoid is not powered it has spring and it should push the top of the lever all the way to left until it hits the hard stop nut. but the lever stops half way. Since the knob is not tight, the only way the lever can move to the...

Is fuel supply open? - The top of level to the left or right? The first picture shows the solenoid fully pulled in, it can not move any more to the right, however, it can more to the left when not powered, but it is stopped by the lever

The only way to find out is to open it up and I do not want to do that if there is possible something else going on. Here are two pictures of the fuel shutoff solenoid and stop/start lever. The first one is with solenoid energize, it is pulled in, the stop/start lever did not move to the stop...

@Guyfang, how does the MPU control fuel? From what I can see the fuel pumps are mechanical there is no direct electrical connection to the fuel supply other than the low pressure pumps. My understanding is the MPU measure RPM and is used to ensure RPM is maintained under load and will shut off...

I am going to wait to get the MPU before starting a thread it will not run, however, I do have quick question. When I first tied starting it and would not run I check to see it fuel was getting up to the injectors, the lines were dry so I tried bleeding the line. I also gave a squirt of starter...

Figure out why it will not start and run and have to thank @Guyfang, read another thread about a MEP-803 not running and he suggested to look at the MPU and when I went to look at it, it was missing. Earlier on I saw two wires not connected and could not figure out what they were for, just...

Again, Thank you everyone for your help, With the help of @kloppk I was able to determine I had a defective S14. It would not allow K16 to energize. I got a new S14 and now it cranks using S1. I now have a new problem and I will start a new thread since it an engine problem not electrical. The...
