I recently rebuilt a 1993 Ve-pumped, CARB 4bt out of a bread van from the bottom up. It will run when you hold a gas soaked rag to the intake, and the pump appears to be in working order since i can visibly see fuel spay out when purging air(and i have tried this with 1 injector removed, which also sprays). By the books my pump gear should be set to "F" and it is. I recently re-gasketed the pump, and installed a new fuel cut-off solenoid. Here's where it gets weird. I get zero combustion on diesel, even though the injectors are working, and the pump is distributing the fuel as it should. I have played with the timing and turned the pump to advance the timing(towards the head) and even tried retarding timing too, but nothing will even give me a sputter. I have the stock fuel pin installed currently, and a 3200rpm gov. spring, with re-worked injectors(75hp). I have also tried aligning the factory mark on the gear case to the one on the pump. Please Help!
