Any luck?

 

Nope i have been **** out of luck. i have to test everything for continuity now.

 

OK just going to compile everything i have done to try and find this problem:

Tested all 6 cylinders for spark-No spark.
changed the crank position sensor&harness
changed the cam position sensor
tested CKPS for continuity.
ECCS fuse-Good
ECU i have 2 of them both good.

The car just turns over and doesnt make an attempt to start.

 

Ign switch, clutch switch, ecu, ecc fuse, alarm

 

thanks for the reminded me, ECU and ecc fuse. Checked those they are good. clutch switch is fine because the car is turning over with out problem but it will not turn on. Ignition switch is about 4 years old. And i have not been driving this car everyday for the bast 3 years pretty much i havent driven it so for it to go bad, possible but very unlikely.

 

does it start if you spray starter fluid in the IM?

 

I have not tried that. I will go get some and try.

 

electronics can go bad at any time

 

At this point I would check everything

 

is your ignition timing correct?

 

True. I havent checked the emanage settings but maybe it reset itself.

I have been using the FSM, using the ignition signal diagnoses(EC 122), i have done just about everything on that list. The only sensor i haven't touched so far is the crank ref sensor. But iirc if thats bad it wont stop the car from starting.

Its on stock timing, 4th gens have coilpacks there is no distributor.

 

crank ref will keep the car from starting

 

Cool. Replacing that tomorrow.

Jesus christ i hope that is the problem.

 

did you try the starter fluid?

 

man i hope u get it up and going after all that hard *** work u done..wish u the best of luck im having issues to mine aswell but not as dramatic as urs

 

^No luck. Replaced the crank ref. No luck there either.

The car might end up at the shop from the way things are looking right now. Something i didnt want to do but im too confused.

 

time to burn it

 

depends on how much its insured for

 

Oh that car is on full comprehensive, I got the gas somebody get me the matches.

 

matches?? i don't think so, but if you really want to..

i think i found your problem, not sure why nobody else noticed it (how many people actually build vq's here?)

you're using a 3.5L upper oil pan, but you're still using a 3.0L crank sensor (by the flywheel)

the 3.0L crank sensor is too short and does not read the teeth on the 3.0L flywheel very good. you had luck starting the car the first time..

you can shave the 3.5L oil pan where the bolt for the crank sensor is, but WHY grind at all?? you're only going to mess it up and make the pan uneven and eventually rust in the area..

instead -- use a 3.5L crank sensor + 3.5L crank sensor harness and splice it into the stock 3.0L crank harness

there's only 3 wires:
Black = GND,
White = Crank Signal,
Red = +12VDC

no need for any grinding, sensor bolts right in the hole, and it works perfectly as it should.
I first did this on my 3.5L swap back in '07 (donor engine was from a 4AT so no need to swap to 3.0L oil pan unlike the 3.5L 5ATs).. fast forward 5 years and a LOT of hard driving/racing, still works perfect to this day


try it, what have you really got to lose??

I was actually in Virginia by Silver Spring visiting relatives 3 weeks ago..

 

I knew that, and i did that a LONG time ago(Aluminum can rust btw?) The CKPS is not the issue. I did all the modifications to the oil pan and CKPS and it works. I did drive the car and i did for a long time on that 3.0 CKPS+3.5 oil pan without starting issues.

Just so you know the back story the car had been starting with out issue for the past couple of months. I had even driven it to the point i got well into boost.

So i figured cool time to wrap this project up turned the car on and drove it up my driveway to turn it around. Got to the end of my driveway and the car stalled. And from that time the car has not restarted from that stall. The problem seems to be the coilpacks are not getting signal but all my sensors from what i have tested are working.

 

This **** still not running?

Have you tried to bypass the Emanage? I have seen an emanage die for no reason, Actually Jime sent me an emanage once that was completely dead, and I tested another Eu that soemone else had issues with, Dead, no start.

 

With those injectors i have never been able to get the car to start without the emanage.I have pulled the emanage and its pnp harness to test it for continuity. So if there is away i can check to see if the emanage has malfunction, because the lights still power up and im still able to go through the E-01 and adjust its setting.

 

FWIW, I've had an E-Manage blow on me out of no where.

I was driving and the car just died and would not start. I could still connect to the EU via USB, indicating that it powered on. It would just not run the car.

I bypassed it and the car ran fine.

I ended up replacing it and Ive been running the new E-Manage for over a year now.

 

Check the injector ground on the EU, mine came loose once

 

that would explain a lot if it was the Emanage.

 

Try finding some stock injectors or dek injectors, something to try to start the car without EU, or with ur current injectors, lower the pressure as much as you could, bypass EU and try to start. The bad EU i tested once, I was able to hook up to it via USB, everything looked fine, but was dead.

 

pulling those injectors back out will be painful, one thing i will do is test for spark with the emanage disconnected. If i get spark then im going to be damn sure it was the cause of the problem.

 

I have a few suggestions.

I know you said earlier that you went over the grounds in depth, but have you checked out the 2 grounds that use to go to the 4th gen lower intake manifold. If those are not hooked up or have a good solid ground that will prevent a spark.

And also when the key is in the ''on'' position does your CEL light come on? Although this is usually associated with a bad ecu it would also indicate a bad electrical issue(which you obviously have came to that conclusion) But its somewhat of a step into the right direction

Good luck

 

do it!

 

ok mystery solved, it was the emanage. After doing some searching i found this and the car got spark after the emanage was disconnected:

Your ing??? I was damn near in tears when i replaced the cam ref sensor and the car STILL didnt start. I thought the Gods had turned their back on me.

 

glad to hear

 

good deal man.

ps i love the language they use on that forum ...

"check the voltage settings for the sparkies..."

"the problem is we cant find the problem..."

"any advices? how to fix this problem..."

 

update

 

Another Emanage has been bought should be here either tomorrow on on Sunday. Now i know i cant use the ignition adjustment. Just leave that **** alone.

 

ugh back to the drawing board. This is becoming one of those situations where its not worth it to contunie. Here is a video, new emanage, new coilpacks, all new sensors(Cam/Crank pos&ref). And here is what happens when i try to start the car:

 

Either your battery voltage is low or that starter sounds a little slow...

 

+1 on a low battery
