Why does my Honda Accord have no spark?
So the most likely cause for this no spark condition is a bad crankshaft position sensor. Checking that the fuel pump is delivering fuel to the fuel injectors is not that hard on your Honda (since you’re able to tap into the rubber fuel pressure hose that connects to the fuel injector rail with a fuel pressure gauge and its appropriate adapter).

What causes the fuel pump to not start?
The fuel pump is running and delivering normal pressure to the engine But, with all that working your engine still will not start. So, the most likely cause, is that the fuel injectors are probably not opening.

What should ignition resistance be on Honda Accord?
To check the ignition coil, measure the resistance between the + terminal (black/yellow wire) and the – terminal (white/blue wire) of the coil. The resistance should be about 0.6 to 0.8 ohms at 70° F. Then check the resistance between the + terminal (black/yellow wire) and the coil wire terminal. It should be about 12,000 to 19,200 ohms at 70° F.
Why does my Honda Accord not get a spark?
