Hi all, i'm currently in a dead end in here. I have a 1996 D1 EDC that was running last week and now it won't. Engine is cranking, no buzzing in Injection pump unless putting ground to engine load relay. 100 Ohms can be read at injector 4. I've already pulled out the harness and connected wires...

I've been working on one of my D1s, specifically the EDC. So far, I've done the EVRY mod, upgraded to VNTs, and installed 2-hole gaskets. However, I'm experiencing a boost cut-off issue. When I hold the boost at 19 PSI, it drops to 15 PSI before climbing back up to 19 PSI. My EGTs peak at 400°C...
