Yes, some were clogged as well. Follow the instructions from post 20 in this thread. That should help you identify what's blocking the flow of fuel. Don't be afraid or hesitant to remove injectors and pumps for troubleshooting. Good luck!

It's alive!!! Properly installed MPU, clean pumps, clean injectors and started right up. Now I'll be doing the electrical installation to load test it. Wish me luck! Thank you very much to all for your support.

Injector are now clean... except one. The nozzle of one of the injectors has ONE hole clogged and I can't clear it. I have it submerged in Diesel Kleen for days in this small ultrasonic machine but the sucker is not budging. I tried also a small brass wire but it is too flimsy for the task. The...

These are Delphi pumps branded Lister-Petter.

Yes, 2-1/4" it is... definitely the injectors need deep cleaning. I cracked them all open and they all have the needle stuck in the nozzle. I'm soaking them one more night and tomorrow I'm cleaning them.

What I could put apart for the injector pump it looks quite well/clean. The spring is not stuck, I can push it in and it moves. I haven't been able to pull it apart since I don't have a tool that can compress the spring to release the washer that keeps it in place. The lever moves but not...

I pulled a set today... the pump doesn't look gummed up but I can't check the inside. The injector is filthy, but it looks ok... I'm not sure how the tip looked when new. I'm soaking them submerged in Diesel Kleen but I'm not sure how to test them afterwards. Here are some pics...

OK... each injector pump has two nuts, one for the injector pipe and another below it (delivery valve holder). If I loosen only the pipe and crank the engine from S1 nothing comes out. Only when I loosen the nut below then some fuel is spilled. Is this expected? Do I need to loosen both nuts...

That was definitely my major confusion, I was not expecting the MPU would reach so close to the flywheel. Anyhow, It's now reading 2.8 - 3.0 VAC after the batteries got re-charged and I could crank it again. Unfortunately it didn't start... What would be the next logical step, check injectors? I...

Guyfang, i appreciate your effort reiterating what the TM explains. I'm 100% positive that's what I'm doing... today i just tried again the old MPU. I measure the distance it's going in with a smaller bolt and it is reaching the flywheel. This time i sanded lightly with 400 grit the tip of the...

I purchased a new MPU and installed it... same readings. It maxed out at 1.0 v just half turn away from the flywheel. Resistance is the same 139 ohms. This is very confusing... what now?! I took pictures through the hole where the MPU screws... i don't see anything blocking it. Any ideas?

I screwed it back in all the way and then out like 1/2 turn... I squeezed 0.8 VAC out of it. It definitely needs replacement. I'll keep you guys posted.

Yes, I followed the TM... all the way in, back 1.5 turns. BTW, how long should I crank the motor? It should register before 15 secs, right? I'll try in a few turning it in a bit more and see what happens...

I just tested it, I'm getting zero VAC directly from the leads of the MPU or from its leads connected to the wire harness. I'm not sure what is supposed to generate the voltage but I assume it's the inductive coil inside the MPU. Should I just try replacing it?

That makes sense, I'll try that today. Assuming there is no VAC in them, is that the last word to confirm the MPU needs replacement?

Well... this can't be good. The MPU read around 139 ohms, but that is not the worst. I cleaned it up and installed back. I screwed it in all the way until it touched the flywheel, then I backed it 1-1/2 turns as the TM reads. I plugged the leads back and connect the battery negative cable. My...

I'm not sure a magnetic speed sensor can be tested by just reading resistance. I'll clean it up and install it back properly following the TM. Hopefully it will make a difference.

It took some digging around but I found it... The tip was covered in a black dust that I blew with just my mouth and it looks ok... I think. Should I clean it more? Is there a way to test it while off? Edit: Is the Dry Cleaning Solvent P-D-680 common mineral spirits?

Hi there, As the title reads my new to me genset doesn't want to start... I purchased this unit recently with 147 hours and I replaced all fluids, filters, added fresh fuel to get it ready to go. I turn the master switch and it cranks but it won't start. The fuel solenoid pulls back and holds...
