Why would a 1987 Corvette 350 tune-port have no injector pulse on the left side but the right runs great if you put new ECM in it?
There are two sets of fuses one for each bank of injectors.Since your getting the pulse signal from the distributor module, it sounds like that might be where to start.Check to make sure there is powere to the fuse as well. MY 86 didn't pulse either-it was the ecm.If there is no light at the injector check ecm connections,( that screwed me up-the connector to the ecm about 6' "upstream" had come partially undone) if there is a light it could be the new ecm .

Why would a 1989 corvette have no injector pulse after changing the distributor module and the ECM Fuel pressure45psi. There is power to both injector wires with ignition on but no pulse.?
Try changing or checking the oil pressure switch next to distributor if it goes bad the engine will not fire or start. Motor (ECM) has to see at least 3 psi of oil pressure to start. And will also shut down if less than 3 psi.

Injector pulse on 1986 mr2?
In a 1986 Toyota MR2, the fuel injector pulse is controlled by the engine's electronic control unit (ECU), which manages the timing and duration of the injector's operation based on engine conditions like RPM, temperature, and throttle position. If you're troubleshooting injector pulse issues, you can check the ECU for fault codes, inspect the wiring and connectors for damage, and use a multimeter or oscilloscope to test the injector's voltage and pulse signal. Proper fuel supply and pressure should also be verified to ensure the injectors function correctly.
