Have a 96 Hond Accord LX 2.2L that cranked up and ran for 2 or 3 min and just cut off. Checking the car out it has no spark on the plugs or the coil. Replaced coil still nothing. Checked distributer and it was full of oil and the wires were brittle so I just replaced with a new one, still no fire. The CEL is not on put on a scan tool no codes at all. When you turn the switch on the CEL comes on the fuel pump primes for 2 sec. and the CEL goes off. Checked injectors and they are firing. With the switch on I have power to the coil and distributer but nothing on the input wire that tells them to fire when the motor is turning over. Timing belt is fine and the rotor is turning in the distributer. I have found 3 grounds 1 on the block to battery,1 on valve cover, and 1 on the intake they are good. What could this be?

The problem is interesting. Sounds like you checked everything and it HAS injector pulse. I was unable to find a wiring diagram online. I did find this link

Hope it helps
You might check the main relay first if you did many electrical exception.

Use a multimeter to test your wiring.
Checked all fuses with a test light under hood and in car. Used OE parts, leaning toward crank position sensor, because I have no firing signal going to the distributer or coil.
Thanks found this online already though tried the LED test on the igniter and there is nothing coming in. Thought maybe a bad ground but all grounds I found are good.
You may end up testing wires from the PCM out to the distributor with the ohm meter. I’ll have to assume the new distributor is good. You have pulse so the PCM is alive. Maybe take the LED tester to the pin at the PCM for the ignitor.
Just checked main relay and one side of its burnt up. Going to go buy a new one will post the result.
Since the injectors are firing does that mean the crank sensors are working? I dont know what else to do. 🙁
OK dug into the ECM (the brain) checked the grounds going into the ECM they were good. Hooked the red lead of my LED test light to a 12v positive and the black lead to the yellow and green signal wire coming out of ecm. When you turn the switch on the LED comes on when you crank the car the light dies, it should pulse and it dont. Any body got any ideas?
Yellow/Green wire looks like the wire for pulse to the ignitor. Did you check at the back of the distributor connector (bad connector pin maybe)? Did you have someone crank over the engine a wiggle and pull on the harness (open harness)? Did you check at the PCM yel/grn pin 21 I think?
