I checked the power relays and they seem to be working fine. Any other ideas?

Ok thanks! I have my Mack mechanic coming out Monday w his computer hopefully that tells us something. So far everything has led to a dead end. The truck runs fine once it starts

How do I test the power relays? They're off to the far left correct ?

I changed the pump, pressure valve in block, bypassed fuel filter, tried another ecu offa working truck, bleed injectors. Etc.

I had it on a comp the only thing that came up was low voltage cylinder 1 any ideas??

Put an ecu from 1 of my other trucks n the issues still there

I bypassed the filter completely and it still doesn't start right

I have a few old r models. The exporters are always trying to buy them

I have an 06 Mack with a 427.

Motor cranks ( like it ran out of fuel ) then fires. But I have to crank the piss out of it. Once it's started it runs fine. Changed the pump and checked all check valves and pressure valves etc. bleed injectors etc. motor is holding a prime to the pump atleast. Any ideas?
