1994 HONDA CIVIC

Hi, I have a 1994 honda civic dx 1.5, manual transmission I was driving pretty low on gas and the car cut out. The power stayed on but the engine did not I had it towed home. Couldnt get it started. I need help anyone with ideas please feel free. I have spark, I did a compression check, checked the fuel regulator and filter. Changed the fuel pump because eveyone I know said it was most likely that. Checked the injectors and they all spray gas like normal. Pulled out all the spark plugs cleaned them put them back in. Checked the efi relay. The car will crank but not fire at all. Checked all fuses. Checked the timing and timing belt. The only thing is the ecu when I go under the glove box and pull out the wire and hook a jumper to it to make my engine light blink with the code the engine light stays on solid and the srs light blinks non stop so theres either no code or something maybe its the whole ecu. So I am lost and my dad who knows more about cars then me is confused as well. Any suggestions or ideas would be greatly appreciated.

Check out the EFI relay. It should be a box up under the dash on the driver side. It is a known problem. You can check the solder joints and resolder or replace the unit. Start there since you have determined that there is spark. There are other things but start with that.

Thank you for your reply I will def check that stuff right now. I talked to one of my friends who knows hondas but isnt in town. He kind of limited it two the fuel pump or the ecu any thoughts on that? We pulled the line right before the fuel filter and put he car on the on position. My dad was able to put his finger over the end of the metal hose and stop the fluid. I dont have a pressure guage but he says it doesnt feel like 40 psi. Should it be that easy to stop. When we put a cup there and let the gas go into the cup a good amount came out but it wasnt gushing so I dont know. Any thoughts or comments on that?

From what I have read, it sounds like your problem is quite similar to mine. I replaced the ignition control module, cap, rotors, spark plugs (needed to anyway) and am down to the main relay or fuel pump.

I bought a new fuel pump but haven't installed it yet cause I want to determine if the main relay is bad first.

I have read that when you turn the key to ON, you should hear the motor whirl sound on the fuel pump for about 2 seconds. I didn't hear anything.

Please let me know your outcome. I hear there is a test you can do on the main relay if you have a digital multimeter. I just need to know exactly what steps to do since I have just bought one but don't know how to use it to test anything.
