Today we received a Cummins L9 Gas engine from Cummins Sales and Service. Cummins has ALWAYS been a BIG supporter of our program and helps us out in many ways. This will be a good training engine for our program.

An update on 07 DODGE with the Cummins 5.9 that we are working on. We replaced the crankshaft position sensor and now we are receiving a signal, but the engine would still NOT start. We checked to make sure we were getting fuel to the high pressure pump and found that there was signs of water in the fuel. We removed the cap off the fuel filter housing and found it had a bunch of water in it. With this much water, I am sure it took out the fuel system. NOT a good sign. Need to talk to the customer now to see what he will want me to do next.

Yesterday a customer came by to talk to me about working on his 07 DODGE truck. I asked him what was wrong with it, and he said the engine had a lot of blow by. I told him to bring it and I would look at it. He then informed me, that the engine would NOT start. Now this is another problem, since the engine will NOT start and it would be hard to tell if the engine does have a lot of blow by. Today we looked at the truck. The engine would NOT start. We hooked up a scan tool and found it had several fault codes. One of the codes was for the crankshaft position sensor. This will cause the engine NOT to start. We will need to look at it a little more. STAY TUNE.
