I have been letting my little bro use my civic and its been driving great until 2 nights ago he calls me up and says the car wont crank at all. I go meet up with him and when he turned the key forward to crank it there was no fuel pump prime, a weird electrical noise was coming from the passenger side dash and when it made the noise the guage cluster lights would dim and flicker like it was loosing power.

So i checked the battery 12 volts
Took the main relay from my r and put it and the fuel pump now primes.
also switched out ecu with another working one.

But when you go to crank it, it still makes a weird electrical noise like something is shorting out and the guage cluster still dims out and flickers. So i disconnect the starter signal wire to see if anything would change and it did. Now when you crank it you can just hear the starter relay click. So i had another starter laying around thinking the one in there was shorting out but still does the same thing.

I am confused on whats going on and was hoping you guys can please help me out here

no one wants to take a stab at what the problem is?

Okay... try the Civic forum. Adios

 

my del sol did that at times....come to find out a prior owner had installed an alarm system and never removed it and was causing my car to freak out...

so shrug maybe look for that? or check for exposed wires?

did the battery have 12V when you were cranking?


When there is no load on the battery, measuring the voltage is pretty pointless.

 

yeah no problems with it, not a battery issue

 

if there is no alarm in the car.
then its definately the IGNITION HARNESS.

 

I hope not but i only have one ground on the motor and the spot on the frame rail was stripped alittle so i am gonna check it tomorrow im hoping thats the problem

 

ecu?

 

tried the stock one did the same thing

How about you fix it the way its suppose to be and see if that does it.

I think he is planning on it?

 

Yeah i had my brother mess with the ground and he said it was no change but he tried to crank it again 10 mins later and it started. So yes its a ground problem and i will fix it just haven't had time to get to my brother's house.
