22T/20H No Start... Edit Weak Spark Now"

[cj91legss]

After searching for awhile i have found no results for my problem that helped.

I just tried to fire up my motor today, and im not getting any spark. (Also getting code 13, Cam angle Sensor)

I don't know if that code will stop muy car from getting spark. Maybe someone can tell me.

I exchanged coil packs, ignitors, ignition relay, i haven't checked voltage at any of then yet bu8t im sure im not getting any voltage. I don't know what's up with the cam angle sensor, it worked perfectly fine when i pulled the motor. I did clean all the metal fragments off of it. The harness side of the connector was all cracke and brittle, so i taped that up. I'm going to investigate that tomorrow.

Other than that i don't uderstand the spark issue. EVERYTHING worked fine before i pulled the motor.

Any help would be appreciated

I'm betting the cam sensor has a broken connection. I'd hit up the junkyard and get one with good wires at the connector. I'm pretty sure without the cam sensor your engine is not going to fire.

went to the junk yard today an i had shit for luck, sensors and plugs gone...... F*cking figures...

[cj91legss]

Now im getting a very weak spark.

I went to the junk yard to get the wires i needed and had no luck, i had a spindle of shielded wire in my shed so i made my own, followed the ecu pinots and what not for my cam sensor, and still no start. then i took my timin cover off and found out that my cam sensor was totally obliterated by the cam gear... SOMEHOW i put the cam ear on crooked.... don't ask i have no idea how i managed to do that, so for all i know it cold hve even been off as far as timing...

Anyways i picked up another sensor from a friend and took cam gear off and put it on correctly and re timed the engine. I'm still getting a cam sensor code (maybe i need to reset the ecu) but still no start. i checked spark and it's really weak, so i checked my grounds and they all looked fine, i even added a few.

It's starting to get frustrating

Anyone else have any ideas?

[cj91legss]

swapped cam sensors, still no start took a plug out andtestes the plug and it is getting spark.

It does try to start but for only a brief MEGA milisecond.....

Everything was kept in a dry location while i was working on the sedan and everything worked great before i started the dohc swap.

Is your battery strong enough? Especially now that you've been cranking the engine over for a little bit?


You mention you re timed the engine.....what exactly did you do, and why did you need to do this?

Also, why did you pull the engine in the first place?

[cj91legss]

I pulled the engine to install my DOHC heads.

I re-timed the engine because the cam gear was crooked. (Mistake i am very upset with myself about)

Battery is plenty strong ive been charging it here and there.

And with a different cam sensor im still getting a cam sensor code...so i guess i will have to try to find another cam sensor

It's just a real bad turn of events with this at the moment, i need a second car and ive been waiting for this thing to be running for 5 months now...

[Legacy777]

Why don't you check the resistance of the cam sensor. The likelihood of all those sensors being bad is not that high. I would check your wiring as well.

[cj91legss]

i checke the wiring. I had to replace the cam sensor wire in the engine bay (ended up replacing the whole wire from the plug to the ecu. Made sure i did it right too. followed the diagram and made sure the wires were in the same location they were supposed to be in. I used brand new shielded wire.

I will check for resistance soon

[cj91legss]

So i just went out and checked for resistance. With the MM set at 20K i got 1.546 on my meter. I don't know what it's supposed to be.

[cj91legss]

Ok so i found out how to correctly test the cam sensor.

As per the directions in the 92 FSM pin 1 and 2 should have a 1 Megaohm Minimum to the ground. I read 0 on my meter. So i guess that's my problem now.

Cam sensors are pretty universal when it comes to turbo legacy and non-turbo legacy right?

[Legacy777]

Yes, they are the same between turbo & non-turbo

[cj91legss]

thank you now i have to wait until pull-a-part has more legacys..... cheapest new one i found was on autozone for 80.99

[beatersubi]

For a cam sensor?
I can help you out, man. I'd be more than willing to sell you one for the one-time low price of $79.99.
No seriously, I have a spare. PM me.

[cj91legss]

Ok now i have an update on my No-Start problem (Which is still an issue) I was able to get my JDM 2 wire cam sensor to work even tho its 2 wire. now the ecu shows NO Codes, which is awsome, but im still getting weak to no spark.

My question now is, How many grounds are there underneath the hood? Maybe i forgot a ground somewhere. Does the coil pack have to be grounded to the intake manifold? I made a bracket and just ran my own ground wire, and a couple others. Also how many grounds are there on the engine harness?

Let me know

[cj91legss]

Checked my coil pack for resistance values just now. I have the Diamond Coil Pack. As far as spark plug terminals for the wires 1-2 shows 20.9 and 3-4 shows 20.9 The manual says it should show 17.9-24.9 so i'm good there Now for the plug itself im supposed to show 0.62-0.77 between 1-2 and 3-2 and im reading 0.00 on both tests. even on my other coil pack im reading 0.00

Do coil packs go bad from just sitting around? Could i infact have a ground prblem?

[cj91legss]

So i think im starting to think i don't understand what's going on with this. i just tried yet another coil pack and im still getting weak spark. it tries to fire for a split second but it just wont start.

Maybe a second set of eyes would help. ihave tried just about anything i can think of myself. so im all ears or eyes now.
Anybody local want to come take a look?

[kimokalihi]

I'd come help you but I can't think of what it would be. Did you check your ignitor? Maybe there's some cracked wiring somewhere, did you trace it all? Probably, I didn't really read the whole thread, sorry...

[cj91legss]

i'd hate to have to trace wires, but i haven't done that. i've only looked at the engine wire harness and it seems to look fine.

Here's what i have done so far
Checked/replaced coilpack, ignitor, ignition relay, fuses, New spark plugs for a turbo legacy, new spark plug wires for a LGT, replaced cam and crank sensor wires (NO CODES FOR THESE SENSORS NOW) now im getting a maf sensor code but that wont stop my car from starting.

[kimokalihi]

Are you sure? Doesn't the ECU need the MAF to run the car? I know I unplugged the MAF on my toyota pickup one time and it started up for a second and died and then wouldn't start again.

[cj91legss]

the car should at the very least start or would started at some point in time, and ran crappy. but it hasn't started yet. I'm going to try a different battery today, and if that doesn't work then im going to ry my car alarm out and see if i actually did miss something with that. Worst case scenario is i gotta pull the dashboard again.

I'm really trying to be ready for WCSS12

[kimokalihi]

When is that? If you're getting 12volts it shouldn't be the battery. Is it cranking slow? If it's not, test the voltage at the starter and see if there's 12volts there.

[cj91legss]

it's cranking alright... it's a pull-a-part battery i got 2 years ago with the positive terminal corrosion special... i should probably buy a new battery soon.

It seems to crank pretty normal.
