Injectors flow problem
My 82 CE would not start after battery change, no fuel flow, checked FB fuse, ok; removed ECM and Fuel Relay and replaced New; checked ECM fuse, it was Bad, RR; sent ECM off for repair and it was non-repairable, got Rebuilt ECM; still no Flow; checked FP and it was bad, RR and had fuel flow and started rough and then died; the injectors appeared to be at Max fLow; removed injectors and put on new gasket and o-rings kit, still no pulsing, just Max Flow.; removed injectors and put in new Pressure Regulators gaskets and found some sludge, cleaned that out and tried to start. We disconnected the electric lead on both injectors and it starred on the excess fuel and the connections the Rear injector and got pulsing flow and ran. Held 1000-1400 RPM with Throttle and then connected the Front Injector and it would flood. The only thing we can do next is New Injectors.
Do you agree that we need New Injectors?
Appreciate your response,

OK, this IS really wonky...all this after a battery replacement? It ran perfectly before dead battery? Buy a 82 corvette GM service manual, it has all the injector troubleshooting you will need to find the issue. NO, the injectors are not the issue BTW. The injectors just dump fuel, not the amount without being commanded.
