I have a 2017 buick regal that got an engine swap from a 2018 chevy equinox. The problem is the fuel injectors aren’t pulsing, the car is cranking but not starting. I’ve been told the ecm was the problem i have since change the ecm and got it reprogram to find out that im right back to square one. I was told to change the Crankshaft sensor which i did and still no start. Had my mechanic checked all the fuses and electrical components, the wiring harness is the original from my old engine. The engine can start off starting spray and runs until it runs out.
