The more broken it gets the easier to find the problem will be and the more confident you can be in your repair.


Sure hope it goes that way, lol.

You got this!

Good news, you can open the 2ZZ block drain on the back of the engine from the top.
Bad news, I also opened the back of my hand on something razor sharp and probably rusty.
Good news, I didn't bleed all over my car too much.
Bad news, I didn't get much more coolant out.

You'll probably need to get some wiring diagrams and compare between cars to see what's different. May be as simple as a different PRNDL switch and some extra wires pinned to it to the cluster.

It's very possible it's a bad CKP, having a code can really cut down on fumbling around to find the problem! I'm still not clear if that ECM times ignition/fuel from the crankshaft or camshaft, the service info I have is a little vague but I think it uses the CMP for telling it when the #1 TDC is to know when the revolution starts and the CKP for measuring engine speed and position between CMP signals. Diagnostics want you to use a scope to look at the sensor waveform and compare to the expected signal from the FSM, you can kind of shortcut that by just checking it's got power and ground and then guessing and replacing it as a maybe if it's not terribly expensive. It is behind the timing belt tho....so you might be doing a timing belt job with that sensor if it is the sensor. However, some cars are kind of stupid and will set a crankshaft sensor code for a bad camshaft sensor, but I don't believe that Toyota is one of the especially stupid ones.
G is the camshaft and NE is the crankshaft.
QUOTE
The Camshaft position sensor (G signal) consists of a signal plate and pick up coil.
The G signal plate has one tooth on its outer circumference and is mounted on the exhaust camshaft.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pick up coil change, causing fluctuations in the magnetic field and generating an electromotive force in the pick up coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor generates 34 signals for every engine revolution.
The ECM detects the standard crankshaft angle based on the G signals and the actual crankshaft angle and the engine speed by the NE signals.


I think the clearest solution is to just move up one year to a 2000 Celica. wink.gif

What a coincidence, I'm doing cooling system work too!

So it's for sure a hot issue. What we need to know is what you're not getting when it stalls or doesn't restart, but being able to duplicate the problem in the driveway is MUCH better than being on the side of the road somewhere. You're going to want 2 noid lights, a spark tester, and a multimeter handy so you can test things while it's failing when hot. Probe one noid light into the 2 wire connector to the ignition coil, the other noid light into a fuel injector, spark tester on a plug wire, and the multi-meter ready to measure resistance of the cam sensor in the distributor as well as the new ignition coil. It would be a good idea to get a fuel pressure gauge on the engine as well just to make sure it's not a pressure issue from a pump failing when hot. Not sure where's good to hook up to on the 5S.

https://www.amazon.com/Lisle-20610-Inline-S.../dp/B0002STSC6/ inline spark tester lets the engine run while seeing if there's spark.
https://www.amazon.com/Lisle-27800-Universa.../dp/B0002SR57Q/ I like and use this noid light at work, put the thick adapters on it and get a set of these probes, crimp them down just a little with pliers and they grip onto the fat adapters and let you probe more easily.
https://www.amazon.com/destructive-Probes-I.../dp/B08FFHG5HR/ probes

You can make due with one noid light as long as you're quick to re-probe things while it's acting up or don't mind making it act up multiple times, for me though time is money so getting it all looked at in one go is worth the price.

I think I am getting motivation to work on the car this weekend (haven't touched it weeks) OR that motivation is coming from diesel fuel prices!!

Do people like to use that radiator flush or just use a garden hose to flush the cooling system?

I was thinking...
- Take out thermostat
- Put the neck back on without thermostat
- Use some radiator flush & water, bleed the system & drive around the neighborhood
- Come back, take hoses off, flush with water via the garden hose
- Install new thermostat & neck, & bleed the system with the correct coolant
- That part of the job is done

Then after the cooling system is good, I can drive it long enough to see if my "surging/ misfire" issue returns.

I wouldn't use flush unless you think there's crud or blockage in the radiator or heater core. I'd just drain the old stuff from the radiator and the engine block, blow out what's in the heater core, then maybe flush the garden hose through the block, heater core, and radiator to see if any crap gets washed out. Fill up with red or pink Toyota coolant, use the fancy coolant purging funnel to get all the air out (helps if the front is up higher like on ramps or stands), then once it's burped all the air out and the thermostat has opened, pop the cap on it and let it cool down a few hours, re-check radiator and bottle level, run it in the driveway again until the fans come on and check it's not running hot, should be good for a drive!

What's the number for that cat converter? I've never heard of a resonated converter but you've peaked my curiosity.

Wow that is some amazing fabrication work! If you find yourself wanting even more heat containment under hood you can wrap the upper section of the header and it'll run cooler than the OEM part. I had an un-coated wrapped header just like that for about 5-6 years before the car left me. I pulled the wrap back a couple times in random spots to check on it and the stainless underneath just had typical 304 surface roughness and cosmetic rust. No rot, no cracking. Not as pretty but certainly effective.

With your timing advance keep an eye on knock, I *think* you could use one of those DIY knock sensor alerts or but definitely a SAFCII to keep an eye on it, I ran at least mid-grade fuel with my 7A with about the same kind of mods because I did hear a little ping with regular 87 octane. Are you still running the stock airbox intake snorkel that runs up and behind the headlights? I assume it's pretty similar to the Corolla/Prizm, it's a surprisingly large restriction and in my case with the vehicle stock it's removal resulted in a very noticeable improvement in low end torque and got rid of this weird flat spot around 2000-2200 RPM.


Interesting side note, that flange between the upper and lower sections and it's gasket are a standard commodity part, if you need a new gasket there I believe it's the same as a Subaru 2.5L from like a 98ish Forester etc. WALKER 31613 which may also be the same flange/gasket a couple posts above for the 3S turbo stuff. It's like they're all picking from the same parts bin or something idk lol.

8f it makes you feel better I do not much better with a smaller engine but have less of a high speed penalty.

Speed plays a huge role in MPG. I bet you'd see over 32 at 55 MPH.

Have to go drive around this week and see if it acts up still. Fuel filter would be weird but not unheard of. Might want to pull the sending unit up and check/replace the pre filter "sock" on the bottom of the pump too. Could even be a failing pump I suppose. Kind of a pain to get a fuel pressure gauge on these to drive around with but it can be done mostly safely.

Oh Lord, why did Toyota make that so confusing? Most cars say they meet federal and that's it or they meet California AND federal. Toyota had to go all extra and be like NOT FOR YOU CALIFORNIA YOU DONT GET THIS ONE CALIFORNIA THIS CAR DOES NOT MEET EMISSIONS FOR CALIFORNIA. Jesus. First time I've seen it worded that way. Your 1999 is some weird **** my dude!

But the underhood sticker and 2 cats say it's California. Do you...have the wrong computer? Call a Toyota dealer and have them pull the ECM part number by VIN.

Tell the dealer "ever since" when it stalls driving home after the airbag.

Aye forgot to tell you, you're part of the Takata airbag recall. Check your VIN to be sure.

No I mean my work is in a bad place. I wouldn't like walk around at night a lot where I work and certainly would not trust a hotel nearby to not give me scabies and bed bugs.

My pride is wounded that I guessed wrong and it cost you money. If you need to check hot parts resistance you can hear the oven to about 210, put parts in,btien it off, and let them heat soak for about 15 minutes then check hot resistance. It's possible it's not an ignition issue, but usually when a fuel pump fails it just stays bad. I'm glad you made it home safely though. Feel free to text me any questions if you want.

Yeah those parts didn't solve the problem. About do for story time but kinda mentally drained/ tired too/ don't care to give a fluck right now.

kindasad.gif was it at least better? Probably the pickup coil in the dist but should check first, there's specs to check that in the PDF. But you gotta check it when it's actually failing or failed. The hardest thing to fix is something that's not all the way broken yet. Sorry my guess was wrong, I feel kind of bad about it. Or the new parts are usual **** quality. For sure need to check coil resistance on the new part tho.

I got a PDF of testing for the ignition coil if you end up needing it to check the new coils are in spec. I'll put up a link when I'm.bsvk home.
