Hey all
So Im currently having an issue right now but first, let me explain what happened first before it led up to my car not starting anymore with 14 codes. Yeah its a lot.

So I was just sitting in my car with the engine on listening to music when the car suddenly turned off. I ignored it cuz I thought I hit the push start button by accident.
Started the car and continued to listen to music. Car shut off again. Checked for codes but nothing. I also just replaced my alternator and my battery cables. Had my battery checked and it was still good.
3 days later I went for a drive just to cruise around and the car started feeling sluggish. Check VSC came on and CEL. Car started stalling while I was driving until it wouldnt accelerate anymore. Car was still on when this happened. Flooring it didnt do anything either. Pulled up to the side and checked for codes. 14 codes popped up. 2 are the VSC and engine malfunction and 12 are Ignition Coil Primary/Secondary Circuit Malfunction from A - F.
Towed it back home and changed my spark plugs because I already have them so why not.
Cleared all the codes and started the car after. Car started but after 30 seconds, the car died again. Pulled up the codes and it says Camshaft Position Sensor Low or High Input Bank 2. found a disconnected wire from the sensor(must have pulled it out by accident while changing my spark plugs) and fixed it. Cleared the Camshaft Sensor code but car still wont start. Ignition Coil Codes are back.
Car has been sitting in the garage for a week now so I've been walking to work ever since lol
Ordered a new Camshaft sensor and its getting delivered tomorrow but I want to know if there are other issues other than the Camshaft Sensor.
Any help would be appreciated.
Thanks!

I forgot to mention one thing.
I ordered a new sensor because I called Lexus about it and they said its "most likely" the camshaft sensor being messed up and preventing the ignition coils to fire up.
Will post updates once I get the new sensor installed.

Car is 2008 Lexus IS350 with 102k miles

If the car starts stalling while you are driving it sounds like it's not getting fuel. Try this: spray some starting fluid in the intake. If it runs for a few seconds and shuts off, it could be your fuel pump. Happened with our '08 IS250 with 152k. You should also hear the fuel pump prime when you turn the car on (but not start).

lol; maybe you don't need a car after all.

My fueld pump is still good I'm pretty sure but I will check it once I replace my sensor.
One thing though; I'm not sure how a fuel pump would trigger an ignition coil code.
Could you explain if you dont mind? Just for stock knowledge.

Lol its a 2 hours walk from my place to work and I'm gonna be driving 29 hours to Florida at the end of this month.

So I just installed my new camshaft senosr and the code went away but its still saying ignition coils A - F are malfunctioning.
I also dont think its my fuel pump cuz I just replaced it at 80k miles so it should still be good.

What work was done immediately prior to this happening? Good chance there's something loose/disconnected.

After we changed the spark plugs we noticed that the wiring on the camshaft sensor were ripped off from the connector so we soldered it after installed the new sensor yesterday.
camshaft malfunction code disappeared after that but the ignition coil codes are back.
I'm gonna try to put new coils first before getting it checked since its simple work and I'm not trying to pay hundreds of dollars to have someone do it for me.

Update

So I replaced all the ignition coils and its still not starting -.-
I'm gonna try spraying some starting fluid to see if it will start and if the fuel pump is bad.
But one thing I don't get is if the fuel pump is bad then why is my car throwing some ignition malfunction codes?

Before you do that, check the fuel pressure sensor. Pretty common problem.

maeveLexi

Can you tell me where it is located?

Update

We did a test on the ignition coils.
Pulled one out and put a screwdriver inside and put the other end on a metal piece to see if it makes a spark.
There was no spark so we're thinking its something with the wirings.

Does anyone know where I can find the Ignition Control Module?

maeveLexi

I give up.
Cant find anything and forums dont have much either.
Taking it to the dealer.

Let us know what the issue was then you find out.

Sorry just saw this.
There was an exposed wire and ended up shorting my ignition.
First it was my coil packs so changing them would've fixed the issue, but as I was changing my coils, I accidentally ripped off some wiring which caused that issue.
Just glad it didn't ruin the new coils and plugs I installed.
Toyota only charged my for labor and not the new ignition they put in.
