Need Diagnostic Help: Engine died while driving on freeway/ Now won't start

I was driving on the freeway today at around 70 MPH in my 2003 V8 Limited with 155K miles when the engine just died. The check engine light came on and the A/T Oil Temp Light came on. I coasted to a stop and turned off the ignition and attempted to turn it on again, but it just cranks, but doesn't turn over. It doesn't sound like the battery is weak. All other electrical seems to work fine. The temperature here today was in the teens so it was quite cold. I checked and I am still getting fuel at the rails when I attempt to crank it.

I read the codes from the computer and it came back with:

C1223, C1224, C1241, C1246, P0504, P0571

They seem to be ABS electrical related codes, but would this make it so that the vehicle would not even be able to start?

I'm at a loss. Any help would be appreciated.

Thanks.

Codes is most likely due to key on engine off and you still rolling and braking. Sounds like a dead fuel pump. With fuel line removed and inserted in a bottle and with key on or cranking it should fill it up pretty fast. If not. Bad pump.
Maybe bad gasses?

Ok, so you are saying it threw those codes because the engine stopped while I was driving and the car was still coasting with the key on while I applied the brakes to stop from freeway speed?

I've already verified that the fuel pump is functioning. There was somewhat of a clunk sound/feeling when the engine stopped. I'm not sure what that was. I've checked the oil and transmission fluid and it doesn't appear to be discolored or have any signs of metal in it.

Clunk when it died? I was thinking timing belt also. Hope not.

Wow I really hope this is not the case. I replaced the timing belt and water pump at 100K to prevent something like that from happening. Shouldn't this throw a cam sensor code? I guess I'll need to take off the timing belt covers and inspect. I didn't smell anything or see any debris.

Zak, that grill insert is awesome by the way.

:thumb3: Thanks man, it took a lot of work to make.

That's all good news and yeah i'd imagine it would throw a cam sensor code too and doubt it would break after 55k
 
I don't know what those codes are, but have you tried disconnecting the battery to reset them?

Does it crank?? If so, then it's either fuel or spark.You said it's got fuel to the rails, then I'd say spark. Coils, plugs, sensor...

Any other symptoms besides a clunk?

I have tried to disconnect the battery. I don't have a tool to reset the codes. I just inspected the timing belt and it is intact thank goodness, so that is not the culprit. :high5: I just went through the fuse box and have no blown fuses. I see no fluids leaking or any odd smells.

What does the A/T Oil temp light mean? That is on along with the check engine light.
 
Abs and brake correlation codes won't cause a no start. Should have checked to make sure your timing belt didnt jump. You won't see a code for broken or jumped timing unless the vehicle is running while belt is off.

Even tho you have fuel. Is it enough/. Low pressure can cause no start. Guess. Next would be to check spark.

By the way. What vehicle is this?
 
I wouldn't worry to much about all the lights you have on. Most the dash lights will be on with just key on engine off. Only way to know which lights are really on is when vehicle is running

This is on my 2003 4Runner V8 Limited.
 
So one of the codes that was thrown is C1224 Open/Short circuit in NE signal circuit. From what I understand, this is the crank shaft position sensor circuit. Is that correct? If that is the case could it be that the crank shaft position sensor failed and that would cause the engine to no longer function?
 
how did you inspect the timing belt did you pull the entire cover: and look at the entire thing or just a top cover a lot of times the teeth come off the belt around the crank before they do around the cams I would pull the entire thing and check it
