Default main relay is good, still no power to fuel pump

I check all the fues, main relay, they are good, I still can't get any power to the fuel pump, also when I spray starting fuild in the air intake, it will not try to start. If any one has any ideas, I would be greatly apreciated. Thankyou

had this same problem going on with my hatch about a month ago, it had fuel and spark (but not a strong spark), it ended up being the ICM. Take apart your dizzy and check the inner components.

Was your car in an accident recently? Because honda's have a safety switch wich disconnects the main powersupply to the fuel pump. The switch activates when the front of your car hits something. Maybe that's it.

I did what the shop manual told me, I have a click and a continuity, pulled the fuel pump out, and put power to it, and it does not turn on.

As far as I know that it never was, been in the brush row for a few years, I dont know anything about a kill switch. I'm not used to these newer cars with an EIC.

so is a fuel problem? if your not sure disconnect fuel line from the injector rail, turn the key on and see if you have a fuel squirt out, unless you have a gauge to test. If pump is working. Pull on of your spark plug wires out and hold it close to a bolt on your valve cover and see if you have spark jump the gap. if not replace your ignition coil! If neither work for you, switch to a know good ecu!

i could give you a million tests to perform, but with the info you have provided... not much i can do.

as mitch hedberg said " i would be a shitty auto mechanic, i would have a customer come to me and say, "my car won't start!" and then i would reply " MAYBE THERE IS A KILLER AFTER YOU! ""
