Not getting any injector pulses on my 87 2.9L Ranger. Pretty sure this ECU is bad. Are there anyways to check and or clean it? Also is there anything else I can check that might be the issue?

Take the cover off and see if any of the capacitors are leaking or if there's corrosion on the circuit board, it happens...

The computer lives on the rpm signal it gets from the TFI module on the side of the distributor which is a known issue, if you have spark but no injector pulse that would say say different things.
