I put a new Pioneer Head Unit in my civic coupe and it had no volume. I checked all my fuses and none of them arte blown from what i can see. I checked all the fuses under the hood as well. From what i can see i dont believe i am getting any spark. I tested the plugs and checked all my wires. The car started right up prior to putting this head unit in. I disconnected the head unit and i still do not have any spark. I have fuel. Everything in the car works. It starts to roll over but wont quite start. No idea what could be wrong

 

TOP IT OFF

 

Check whether the distributor is getting battery power when the ignition key is turned ON.

If so, check the coil and then the igniter unit in the distributor.

 

UPDATE:

I had to wire a new end to the stereo harness because the prior owner had a chop job in there....I had the red wire with the green stripe wired to the red wire with the black stripe.....they were backwards....so i switched them back and i got sound on my new head unit....

my car started before i mixed those wires up and ran like a champ...

anyone know what could have happen by crossing those two wires?

 

I recommend that you carefully double check for a blown fuse(s), and then do the power tests mentioned in my earlier post.

 

any idea what fuse it could be? i checked the starter fuse under the dash three times and its good (7.5 amp)

 

i checked for power to the modulator under the distributor cap and i have power to those two wires that are screwed in to that modulator....i think that mod. is bad??? now how do i get it out...it wont come past that wheel in the distributor

Okay, you have power to the distributor with the ignition key turned to ON. Correct?

Then take the coil and ICM to AutoZone (or a some other auto parts store) so they can tell you if one tests bad -- my guess would be the coil.

(you need to pop the starter until the rotor is positioned to give access to the screw holding it in -- make take some time)

 

ok i got it out ok...taking it up to auto zone now...dont think im running in and out of the house keeping you updated on my progress...i have a laptop in my garage lol....thanks for the help...hopefully this is it...

 

Coil test came back within range....now im not sure what it could be....the primary test was 0.1 ohm off but the secondary was in the dead middle of the range....

the igniter box has magnetic power to it but i cant get the test light to light up on the two wires....idk

top the top

 

Call AutoZone and ask whether they can also bench test the igniter unit/ICM for you. If the coil is good, then the igniter/ICM is the prime suspect. (Also make sure the ground wire on the thermostat housing is tightly connected and not corroded.) If they cannot test the igniter, purchase one and return it if it does not solve the problem.

By the way, occasionally, the bench test of a coil will yield a false result. So if the igniter is fine, then next purchase a coil and return it if necessary.

 

Ok...i gave up for the night...its getting late and im getting annoyed. Ill try to work on it more tomorrow if not i will next weekend. I dont have time during the week really. keep checking this thread ill keep you updated...Thank you a bunch man


Also autozone is closed for the day lol

By the way, you are likely very close to the solution now, so get some rest and a fresh start tomorrow.

 

You had battery voltage running to your speaker if you wired red with black stripe to red with green stripe. Check your underhood fuses, one of them might have popped.

 

I checked all my fuse as i stated many times within this thread

I looked up the prices of the ICM and its like $170. But my distributor also needs a new O ring because it leaks a little bit of oil....SO i went hunting locally and found a buddy of mine who will sell me a new distributor for $25. I need to contact him today...

 

I got the distributor off that kid...come to find out it was a D series distributor so i called him and got my money back.....Then i went up to autozone and got a new ICM....put that in and still no spark....i dont know where to go from here.....any ideas?

 

to the top...I NEED HELP

 

Return the igniter ASAP and exchange it for a new coil.

 

i just tried a new coil....still no spark...

 

Do you hear the fuel pump prime for a few seconds when you turn the key to ON?

How are you checking for spark? Are you checking all four plugs for spark?

No-start without spark can also be caused by a snapped timing belt.

 

last thing i can think of is a new main relay....i have one at my buddy's shop but i cant get it til 6...so i am going to go swimming for a bit bc its hot as hell out....be back in a bit...

timing belt is fine...i had the car running and mobile 30 mins prior to changing the head unit...came home...shut it off and replaced the head unit...belt isnt snapped...

Fixed...thanks for all your help

 

Congrats on the fix. What was the solution?
