On my 1995 CH 613 with a 300 Mack motor in has hard time firing. I put on all new filters and was wondering if a drain back valve could be bad. The motor has a Primary and a Secondary fuel filter the Primary fuel filter sounds empty and the Secondary sounds full. The pump actuator solenoid is working. Need a little help here.

My Mack CH 600 Has Trouble Starting

I found the problem. Up on the firewall you have your starter relay and beside that is square box that has two prongs and that is a ignition ground relay and that burned up. -

Well if you ask me it sounds like a power divider. I just had a truck that did the exact same thing as yours and the cam inside was bad. It only popped every now and then. -
My Mack CH 600 Has Trouble Starting

What about a ground relay on the firewall next to the starter soleniod, could that be a problem to, because it smokes sometimes and I'm replacing that. -
I have Mack CH-600 with a mack 300 motor. We have difficulty starting it when it is warm and cold. It's wierd you spray either to it and it fires right up. Fuel filters are tight, no leaks on any fuel lines, it has a new drainback valve. So I got curious and tap on the actuator on the fuel pump and it started. Now was that just luck or could that actuator be bad. If it is bad how do you test it.
