I got a 02 Chevy Silverado 1500 with a 5.3. She aint starting. I will try to give you everything you need to know.

A week ago I drove out my truck on a really hot day. After she sat in the sun for a few hours she didn’t start for a bit. After many tries she started. Another incident like this happened again a few days ago. Now she won’t start at all.

She does crank and I am getting spark and compression but no fuel. I was able to start her with starting fluid and had the check engine light go on for the few seconds she was running. It was only running on the starting fluid.

The fuel filter was changed last year, so I do not think it is that.

I’m not sure if you can check a trouble code when a car won’t start???? I heard you cannot. Is there a safe way to check a trouble code without a running engine?? Not sure if spraying a full can of start fluid in is the safest.

If you need me to clarify anything with this, feel free to contact me

Thanks for your help

When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?

Just tested the fuel pressure. It's about 50psi. Any thoughts now? Still trying to get a trouble code reader.

Just rented the trouble code reader and it would not read. The reader was working but was not connecting to the computer. Found out that the cigar fuse was blown. I read that a blown cigar fuse will make any reader not work. I'll get the fuse and try again tomorrow.

Just checked it with an obd 2. The icons "EVA" "CAT" and "HTR" are flashing. The icon O2s was on in the begging but went away. I was able to start her up though. Also, the security light turns on right away. What do these codes mean is there a way to fix that stiupid light from going on?

Thanks for your help guys.

Being that my truck has a stock ignition, can I use the trick of unbolting the battery for a while so it will reset or will that not work?

Thanks for answering my questions, you all are really helping me out.
