My Acura Legend was having a hard time starting but all of a sudden it wouldn't turn over at all. Battery is good. Starter is new. Replaced cap and rotor, plugs, fuel filter, checked the coils resistance, okay. Cheched injector resistance, okay. The engine cranks over but acts like it won't fire. Checked to see if fuel pump was okay, it pumped about pint in just a matter of seconds (when changing the filter)

Any suggestions?

Do below and comeback with some testing results

Get a helper disconnect a spark plug wire or two and ground it to the engine. Have helper crank engine over. Do you have a snapping blue spark? If so, you have a fuel related problem. Check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer.

Verified fuel pressure, okay.
Verified coil resistances good,
Checked main relay.
Finally, pushed gas pedal down to floor and cranked it over. It started!

Already checked spark, okay.
Changed out cap and rotor, fuel filter,
plugs, air filter.

Thanks for input.
