3176 only starts with ether
Ok. So, found a used ECM. Installed it and within half an engine crank it fires right up. Now I just need to transfer ECM information to get the same HP settings. Haven't checked fuel pressure yet. Might just do it anyways so I know for future reference. -

Also, disabled the engine monitoring parameter and that did not solve it. So the TIB did not work for me. -

Cranking speed is from 155-205 which is within the 100-300 to start according to SIS. Still waiting on proper fittings and gauge to get accurate fuel pressure while cranking and running. -

This is the only information I can find on SIS in regards to fuel pressure. Does not give a starting psi. I'm getting around 60psi at low idle. I'm going to install a liquid filled gauge as well so I can give a more accurate number.... Fuel Transfer Pump With the engine operating at rated... -

Quick update. I received some parts. Of course the relief valve for the transfer pump was the wrong one. I reassembled the pump anyways and put it in the truck since the relieve valve looked fine and I didn't want to wait to do more testing. The regulating valve and spring for the siphon block... -

I will give it a try once the parts are all installed. -

So there is a sensor on the flywheel. I guess I didn't look hard enough before. It says freightliner on it so I'm guessing it's on the oem side and will have nothing to do with starting. Probably how tach works in dash. -

Found this. Seems slow. SMCS - 0374; 1000; 1450 All Caterpillar Diesel EnginesGenerally, the cranking speed needed to start Caterpillar diesel engines is in the range of 100-120 RPM. When warm, the engines will start at a lower cranking speed. In cold temperatures, battery, starting motor... -

Just found out parts are earliest tomorrow. They are in the US, so hopefully tomorrow noon. This plug is not in the truck either. It is on the block, above and to the left of the ECM. It is a different 9 pin than usually on trucks. I think it's what gensets might have? It's a 9 pin but doesn't... -

Serial number I have is 7LG10625. Can't see arrangement number. Should get parts today to see about the fuel pressure. This is not a 3176B. 1 and 11 is battery positive, 12,21 battery negative -

I hope it fixes it as well. Still going to have to deal with injector codes at one point I assume though. Can't see fuel pressure fixing injector codes. -

I have ordered the relief valve and spring for the transfer pump as well as the poppet/regulator valve and spring in the siphon manifold. Should have it all tomorrow and will put it all together and try again from there. Didn't think I needed the whole manifold but I will see how the poppet... -

According to SIS anything over 6 volts while cranking is good enough. The numbers are higher with the booster on though. There is no voltage drop from the batteries to the ecm. This ECM only has 2 key on voltages and 2 grounds. The positives come from the same wire on a harness farther up and...
