my car wont start anymore....dont know why.....it cranks but the motor wont run...it doesnt throw any code.....when i mess the engine wire harness down at the ecu plugs, I can hear this clicking noise...sounds like a relay or fualty wire but how do i know if one of my wire is short or the relay is bad? I check my injector wires and still intact well, my rc injectors are new, new fuel filter, fuel pump still pumps when i turn the ignition on, timing belt is set correctly, check the fuses inside and underneath the hood........im confused...any input will help.....

its obd2-obd1 if that helps......

my hondata still powers ups.....I drove it one weekend...parked it and next day when i try to crank it...wont power up anymore....

 

Check the Main Relay for the Fuel Pump under the drivers side dash. If that is clicking it is probably bad. I have seen this Relay go bad on a few Integras and Civics.

 

try to hook up the obd2 ecu again, maybe the ecu conversion harness is messing up.

tried it...wont start....ill check the relay though....a picture of the relay can help if somone has it...

 

how do you check and see if a relay is bad?

 

Swap it out with another one of course.

 

if your main relay is bad then that often cause u to get spark but no fuel.check all grounds, check for spark

 

you could also check your fuel by taking off the 17mm fuel line going to the fuel filter from the firewall,then turn the key to see if fuel is being pumped.(be ready to cut off the ignition due to fuel-sray),

did that already....fuel sprays out from the fuel filter so i know im getting fuel, i checked my spark plug wire so see if im getting sparked and it has sparks.....im about to give up.....ive thought of every possible solution...i honestly think its faulty wire from my wire harness becuase when I move it around i can hear this clicking noise .....could be bad relay but damn which one???? and how do I know its bad?

 

ttt

 

try to swap out the relay's. you can get one from the junk yard for like a dollar or something.

which one though? there so many.......and how do i know if its bad...thats my question....

 

If you have a book check out the wiring diagrams and by process of elimination you can probably narrow it down to a couple of them, then you just swap the ones that are suspect with others that match. Are you sure the ECU is OK?

 

In my own opinion, if you have the stock ECU, I'd toss that in just to see if that's the problem. Might even try having a friend move the harness around while I try turning it over just to eliminate that thought. For a buck each, I'd grab as many relays in there as you can and go through process of elimination. Sorry, know it's not the best advice, but it's what I'd do even though it's probablly not right.

yes i did swap out the ecu for my other stock p72 ecu and still nothing. Ill figure it out eventually....

How about the coil? Are you absolutely sure you're getting spark? Had a friend that couldn't get his car started over the weekend, ended up being a bad coil.

are you talking about the distributer? ill check and see.....

 

check your starter and ignition

 

Yea I think the stock coil is in the distributor. Right?

 

ill look into it...but i dont think its mechanical...i think its something electrical...

 

do your injectors have pulse width? your car needs three things to run, air, fuel, and spark. air=check compression. fuel=check pressure and injector pulse. spark=check spark. process of elimination.

 

Well yea that's what I mean, I don't think you're getting spark. Have you tested it to try to find out if you're getting spark? If you take one boot off the plug you should be able to put it next to the valve cover and have someone crank on the car, if you see spark jumping on the valve cover you have spark.

 

i think main relay also
