About two months ago i started having problems with my 05 Scion tC, I had the dealership change the ECU and it still does the same thing and when its hot my car won't start, if I try to crank it at dark when its cool it will start but only run for like 5-6 mins and cut off and won't crank until its cooled off again.
I've took it to the dealership they said the ignition coils were bad, I bought new coils and installed them, still not running, I've also bought new spark plugs nothing. Somebody told me it was the crankshaft sensor. Has someone had the same issues also?

Please HELP!!!!!!

If the crank spins, you at least know that the engine is likely fine. Crank with no start points in the directions of fuel problem, timing problem, or spark problem. You changed the coils and plugs, so it's not likely a spark issue. Could be that the timing is off or engine not getting fuel. Check EFI fuses and relay.

 

Ive had all that checked and still nothing!!!

 

dealer might be giving run around to younger folks life is hard this stuff still makes me angry. Insist on the master tech looking it all over. They should be able to figure it out.

I don't know if this works, but tell them after they fix it that you're not paying for work done if it doesn't fix the problem. E.g. the replacement ECU

they're called the stealership for a reason

 

I would definetly check the crank position sensor and the cam position sensor, Your timing could of also jumped.
