Re: Starts and dies

Code readers are dirt cheap for a basic one. You can get one on Amazon for $15. Harbor Freight has one that is a little better than the super basic ones, but still nicely priced at $40.

One issue I ran into, on a Toyota no less, was the coolant temp sensor. I had actually forgotten to plug it back in upon reassembly after changing head gaskets and same thing. It would start, run for half a second and die. Once I put a code reader on it and saw the coolant sensor code I realized what I did, plugged it in and it fired right up.

If the coolant sensor isn't plugged in or fails the ECU thinks its -40* and just dumps fuel, so much fuel that it can't run. Another possible issue could be a cam or crank sensor. If there is a code reading that code could save you a ton of time rather than just guessing.
