Fancy prairie, Illinois
I'm working on a cat 3126 7as prefix, heui injectors. Truck died going down the road like the key was shut off. The engine is in a 99' Chevy topkick/c6500 with an obd style connector, no 9 pin Deutsch connector anywhere I can find, no dealership has the right connector, I ordered one but is 3 days out. Today I checked the 70 pin ecm plug for power, ground and ignition, checked good. Builds 1500 psi at icp sensor with analog gauge. I was told to throw parts until it was running, I replaced timing sensors, icp sensor, ipr valve. Fuel primer pump is hard, was hard immediately after dying. Not one bit of smoke out of the exhaust. 5v at all the engine sensors. Any ideas?
