wiring amazement

[kbusch18]

okay so my 87 inline 6 will turn over it seems to have a timing issue but thats the least of the worries

 

to begin it is a wiring mess when i first stick the key in and turn to lock it makes and awful buzzing noise underneath the steering column

 

when i turn it to on i am getting no juice to the fuel pump i think i had found the pump relay but not shore is this a ecu problem or what i replaced everything to do with spark

[JeepcoMJ]

the buzzing is normal. pull the blue or black box that's on the left side of the fuse box out to get rid of it.

 

other than that, ignition switch...

[kbusch18]

it could still be the ignition switch where is that bad boy located

[JeepcoMJ]

top side of the steering column tube, down by the firewall.

top side of the steering column tube, down by the firewall.

 

Yup, the key lock cylinder (commonly called an "ignition switch") actuates a long rod which runs down the column to the actual switch closer to the firewall.

[kbusch18]

ok i will look to find it i guess it cluster of plug ins

 

i am just wondering would it still be attempting to turn over if that switch is bad

[ComancheKid45]

I didnt know Kyle Busch liked working on MJs, guess its something to relax him after his altercations with Nascar Officials :rotf: :peek:

 

Ha ha sorry for the Hijack :rotfl2:

[Comanche County]

The buzzer is in the fuse box, that's probably what you hear like Jeepcomj said. I don't believe the ignition switch can make noise -- unless it's on fire.

[kbusch18]

ok i found the thing making that annoying noise and pulled it i am still wondering if the car would still be turning over if the egnition switch is bad

 

like i said the fuel pump is getting no juice but it turns over slow but it turns over

[kbusch18]

and yes kyle loves mjs

 

ha and come on hes a riot giving the bird to whoever he wants booyah

[Comanche County]

This may be a shot in the dark, but check the ballast resistor under the hood on the driver's side inner fender.

the buzzing is normal. pull the blue or black box that's on the left side of the fuse box out to get rid of it.

:agree:

[kbusch18]

the resister i don't know where that is what does it look like

 

i changed out the ignition switch the only change from before is now the fuel pump is priming which is wasnt before

 

it still is not starting when i first did it, it wouldnt even turn over i know that there are these two medal rods that run the steering column one goes to the ignition switch what does the other do its seeded on a spring loaded whit plastic peice

 

not to mention nothing works accessory wise either headlights, windshield wipers, turn signals

 

it is turning over tho same as before

[Comanche County]

It's time for the electrical gurus to chime in...they're enroute as we speak.

 

The blast resistor is the white porcelain object on the drivers side inner fender. Look for cracks in it. t's fairly obvious.

[kbusch18]

ha yea they will be here soon

 

ok i seen that resistor on a mj at the junk yard but i do not have one in my jeep what color wires should be going into this thing

[JeepcoMJ]

start testing the fusible links by the battery, make sure everything is plugged in to the starter relay.

[kbusch18]

o done that ha its something that isnt allowing it to get spark

 

any ideas as to why the accessories don't work at all

[Akula69]

The ground for the accessories is down on the lower driver's side of the dash under the headlight switch. Check that, as well as the tightness of the grounds by the fusible links.

 

Check the fuel pump ballast (driver's side fender well by the air box). Make sure both wires are attached. If you are undertain it is good, make a short jumper wire and connect the two leads. Also - check for fuel - the gauge can sometimes be wrong.

 

The two rods are for (1) the ignition switch and (2) the high beam headlight switch. The "spring-loaded" white switch you speak of is the high beam switch. make absolutely sure both ignition switch plugs are fully inserted.

 

Check for spark at the coil by using a spark tester (do NOT pull a spark plug and lay it on the valve cover unless you want to light up your life!). Pull distributor cap and check for moisture inside and carbon deposits on cap and rotor. Check stator is not too rusty (however - if you are getting spark at the coil then you're getting spark at the plugs)

 

Let us know about these things and then we'll go from there.

 

Good Luck!

[kbusch18]

hey thanks guys

 

i put in a resistor because he was jumping those two wires

 

and i put in a new coil module the part the coil sits in and most of the accessories now work and she started right up

 

awesome thanks guys

[ZLecerf]

if i were you i would check your grounds .....cause thats sounds about like what was happening with mine and it was just a ground that i missed.

[raviolli]

i know that there are these two medal rods that run the steering column one goes to the ignition switch what does the other do its seeded on a spring loaded whit plastic peice

 

i think you and i have the same problem. only difference is ive only seen (or been able to mess with) my MJ once. its sitting at my girlfriends dads house about fifty miles away. if i can start it and get it home, its mine

when i got there, most peices to the steering column were taken off and on the floor, though i did some disassembly to these "metal rods"

all the work was done in the dark. we went trhough about 4 bulbs with the droplight before calling it quits for the night, but i did discover that this other metal rod you are thinking of goes to the steering lock. there is a metal plate under the steering wheel with notches cut out of it for the rod to slide into to lock the wheel. when we pryed this rod out (with the spring and white plastic peice falling to the floor) the wheel was no longer locked and would turn freely
