Having a no start issue on a Cat CS563E smooth drum roller. Machine ran fine, operator shut it off and came back an hour or so later and it wouldn't start. Checked fuel system and found the lines without fuel. Primed it up and got it to run. The next day it again would not start. Primed it again and still no start. Checked with ET and had an active code for engine oil pressure. Found the oil psi sensor was cracked and had no continuity between any of the 3 pins. Replaced sensor and that took care of the oil pressure fault. Still no start but now getting codes 1648.04 and 1648.07 for low voltage to fuel injection pump and fuel injection pump not responding.
Did get it to start twice by wiggling the engine harness while cranking but after it ran for 40-60 seconds it would quit like as if the key was turned off. So we went thru the fuel injection pump electric system troubleshooting guide, originally had intermittent low voltage readings but got that straightened out. Also checked voltage at the canbus wires at the pump. So far all the test results match what the troubleshooting guide says they should be.
Tried to test the fuel pump solenoid but it can't be accessed well enough to get a meter to it.
I don't really know what to check next. It's a Perkins/ Cat 3056 6 cylinder Diesel engine. 24 volt system. Cat CS563E model smooth drum vibratory roller S/N ASAO1162. Machine has only 2400 hours on it and when we did get it started it ran very well which makes me think the injection pump itself is fine, that there must be a problem with the pumps control components, or a wiring issue. I tried to order a new engine harness but the $1,500.00+ part is not readily available from Cat, might be able to get one a month from now but the machine is needed like yesterday.
If anyone has experience working on this machine or the 3056 engine and has any advice, I'd be very grateful for a response. And I'm typing this up on my phone so I apologize if the format is bad or hard to read. Thanks for taking the time to read this far and for any response you may have. Have a good evening.
