Although it still looks plenty long I wonder if that was done because the PO had to cut back some of the wiring that was damaged from heat and they simply made an extension?

I took it off when, after I got home, I couldn't start the car again and Got 0322 0321 codes.

Drove down the block, and it sputtered and died.

When I had taken it off, surprisingly now my cigarette lighter has power.

But the interior lights don't turn on and the alarm lights don't flash when arming now.

Put it back and still no interior lights and no accessory power.

I was beginning to think it was some sort of make shift ground as there is obviously electrical issues.

But im at a loss. Its simply a coil plug extension, with a lead wire mounted to the cover.

Dunno

If you test all the coil plugs:
Terminal 2 (large brown wire) should all show continuity with each other and are grounded to the firewall.
Terminal 4 (smaller brown/yellow wire) should all show continuity with each other and ground to the valve cover.
Terminal 1 Red/Green is 12v from fuse 29 (20a fuse)
Terminal 3 Each go to the ECU separately.

Driving ast night, and felt a jolt. Went to accel and car died. Threw p0322 0321 codes.

Limped home and parked it.

First thing this morning purchased and installed new ess and now no start yet no codes

This is what the red wire off coil 1 is connected to

That part is an aftermarket suppressor, I suggest you remove it.

You need to replace the damaged sections of the harness to all 4 coils.

 

What terminal on the plug is it connected to? Should 4 but possibly #2.

 

It was on 1.

I took it off thinking it was not needed. And that's why I suggested electrical gremlins, because after I removed it, my cigarette lighter and ashtray began to work.

Started getting everything back in order. Purchased this used a few days ago.

Got the 322 code.

Replaced the ess. Now won't start.

Took plugs and coils off, all are used and will be replaced. Yet now gett code 354

 

are you getting spark at the plugs?

ESS only inhibits fuel delivery AFAIK but you may have an ignition issue

 

Ya getting a 354 code now

 

You need to keep it in one thread. Without everyone knowing the other issues, there is no way you'll get a good answer.

 

Same car. I noticed this unknown mod last night when the car was fine and running. This is new today

 

Yes, but it could all be related.
Do these tests for the coil pack wiring

 

I don't have a vagcom nor access to one atm.

Started testing coils, and couldn't get a reading from my battery. Moving the proves I'd get brief 13-18v readings, but would disappear as soon as they would appear.

Getting irritated at yet another pandoras box, wanted to trace the wires. Very brittle and a good detour from the frustration of the current task

When one coil plug completely dismantled itself upon removal (the entire insides shattered into pieces. Replaced that one and found this on #3

Obvious problem I will correct, and then on to the 322. Will update

Sounds to me like that meter is set for AC Volts, not DC Volts.

 

You’d be better off trying to find a complete replacement harness or enough of one from a junk yard to make a quality repair.

While this is a bit expensive it would allow you to take the repair back quite a ways into the old harness and replace everything downstream at once.

Harnesses from junkyards are $26.
Since my maf portion is intact, I should be able to frankenjimmy one.

In the meantime, I cut the wire sleeve down to the puck, and the wires in that area haven't been affected by elements. I know the remaining 2 clips will need replacing. Will install #3 tomorrow am, and see if anything has changed. Reading my generic obdii the code for p0322 was no longer present. It was p0354 coil D primary/secondary circuit. Replaced that clip. And read p0366, open circuit. I'm guessing that's due to #3 being cut and exposed. Where as #4 is repaired so it's not throwing the p0354.


I Appreciate the input and time.

 

That device in your hand in the last picture is a capacitor and is part of the ignition circuit.

 

If I removed it, then it would leave the circuit open?

 

Found my open circuit. The bracket from the alternator completely broke off.

Seems all the plastic material is all compromised

 

Should be able to find a replacement voltage regulator on rockauto or something easily.

 

I had noticed the intercooler elbow on the passenger side was gunked up. Nothing on IC side. This is the cv boot exploding and the grease therein?

 

I have a question regarding my cv axle. Fed ex is delivering my new one today, so I got my current axle out.*delivered, and the axle is too big. Running the Vin I find out this is not an 03 as the PO sold it as, it is an '01

Yet I was concerned when beginning, as the entire cv axle that connects to the transmission side was loose.

The bolts were in it, yet the entire case was rotating a few degrees either way when I began to break the bolts.*

Is this something a little more severe or is it just age that has loosened the connection?

 

The axles are the same for a tip trans from 00-05. There are thicker axles for the 4Mo, but they are the same length and interchange. It's normal to have some play in the differential when you go to break loose the bolts. Did you compare lengths with both axles fully compressed? Maybe it's for the other side as one side is about 1" longer (I think it's the driver's).

 

I double checked.

The wheel side is bigger than the one I pulled out.

Talked to the rep at GAPs and since 03 was a split year, he did more research. Yet now, I find out I have an '01 not an' 03

 

I'm unsure how to get this into service position. Everything I've found is for 2003+

The clips inside the bumper are going to split if I continue to push forward as it states. Is there an actual 2001 service position how to available?

 

You don't need to put it in service position to replace the axle, but you will need to get the correct axle.

 

Service position is need for what I'm doing. The axle was a side question as to the movement of the bracket on the transmission.

Is it supposed to rotate around offsetting the thread holes?
