I screwed up while i was repairing an electrical wire in the main harness that runs across the front of the motor.I was an idiot and didnt disconnect the battery and one end grounded out and now the engine wont start.

It cranks normally but im not getting any power to my HKSII(no red light is on).I checked all the fuses and they check out good....also with the key in the run position the electric fans stay on all the time.

Anybody have any suggestions were else to look.

 

did you check your fuses under the hood? or the fuseable link? once i crossed my wires on my maxima duriung a jumpstart and it was my fuseable link was blown.. $3 fix

 

Hey Doug i checked all under the hood by the battery and under the dash and all were ok.I got to locate the fusible links as i have no clue as to were they are.

 

fuseable link should be under the hood.. it looks like a huge fuse

 

It takes a while just checking all fuses/links.. We have like a billion.....

 

Any idea were?I suck when it comes to electrical problems.+

 

should be near the battery some where.. i'll check the FSM when i get back to CT later tonight

 

oh btw.. there is a third fusebox when you take all the plastic covers off around the battery.. check that one too

 

Thanks man.

 

this guy said the fuseable link are big fuses next to the battery.. check it out

I did and they look ok.Dammit i know im just over looking something small.

 

How are you checking the fuses? You should be using a meter. Sometimes they are hard to tell if they are blown with a simple visual inspection.

If your ignition module isn't getting power the fuse for that circuit is behind the battery. Assuming you've got all the wires "fixed" you should have 12vdc on the power wire going to the ignition module (should be a white/blue wire). If you don't have voltage there trace it back to the fuse and check that fuse with an ohm meter.

Why were you repairing a wire? What was the wire for?

 

The wire is white/blue and when i had the stillen the fmu had on wire spliced there.When i got rid of the stillen i just cut the fmu wire and taped it up so today i decided to fix it the right way and put it back into the harness and screwed up.

 

I see one fuse block were the battery is is there another one behind the battery also.

 

Well i just visually checked all the fuses in the second fuse block and they are all ok by sight since i dont have a meter on hand.Im lost......

 

Pick up a continuity tester from radioshack or invest the $30 in a multimeter. Make sure the resistance across the ends of each fuse you pull is 0. PITA. There are a bunch of fuses in the IPDM behind the battery (the cover slides off the top - release tabs on either side). You pretty much have to remove the battery to get to them. What wire did you short out? That could provide a clue rather than testing everything. You may have fried a relay also (contacts permanently fused).

 

I think its a relay also but the wire is in the main harness that runs across the front of the engine.It is white with narrow blue line and when rejoining the wire together i touched ground by mistake.The HKSII red light is out and the fans run with key on run position.

 

Fans on with key in run position is typical when the ecu is not connected or powered. Sounds like a blown fuse to me, not relay. Have you checked the fuses by the driver's left foot?

 

Yes they were the first ones i checked and visually all look fine.When i get to the shop tomorrow im gonna bring home a multi meter and test light.Hal which fuse is the ecm fuse...do you recall.

 

I would check fuse 82 - it should be the top right fuse in the IPDM behind the battery (assuming you have an '03 Z). If you have a different year Z it may be in a different position.
