Gave the car a bath last week and when I went to start it to pull it back into the garage, it won't start. It will turn over and run for a second then shut off. I have checked all of the fuses and do not see a problem. What else am I missing here guys? Please guide me in the right direction for what else to check.

Do you have a stock MAFS?

You washed the car, then it failed to keep running after the wash?
I'd check the air filter housing to see if you flooded it with water.
The air filter will get soaked with water and prevent enough air for idle.
I did this once when I flushed my cooling system.

if your fuel pressure shows good and holding, then supply isn't an issue. is it stumbling or smooth for the second it runs? water has a funny way of finding its way into ignition systems...coils, wires.....you need to do some basic diagnostics....check spark, injector pulse, scan tool....other than that, you've got those elusive Gremlins

time to call ghostbusters......Sounds like your chip has an anti theft sequence in it, but, I am sure you would know that.
Have you checked any of this? fuel pressure gauge, spark tester, noid light...see what's dropping out.....if your fuel pressure shows good and holding, then supply isn't an issue. is it stumbling or smooth for the second it runs? water has a funny way of finding its way into ignition systems...coils, wires.....you need to do some basic diagnostics....check spark, injector pulse, scan tool....other than that, you've got those elusive Gremlins

verify power to the ecm, I had one hell of a time diagnosing that problem.When it would sit for awhile it would start and run for a sec but die. I had fuel pressure at the rail(40psi) and had spark. When I sprayed ether into the throttle body it would run fine. I had no injector pulse just like bison had touched on. Its an orange wire on the passenger side engine bay. Just another variable to eliminate.
Turbo Tweak chips can have an anti theft sequence, if you ordered it that way. That is what I have. If you ordered the chip, or, if you had the car running earlier with that chip, then you probably do not have anti theft. But, if this is the first time you have tried to start the car with this chip, then maybe. Contact Eric at Turbo Tweak, or, contact the previous owner of the chip, or, switch chips if this is the first time trying to start the car on this chip.It is a Turbo Tweak chip and I do not see an anti theft sequence in the instructions. Any additional info on this is welcomed. I have changed out the fuel pump relay and the MAF as well. Still no start. I'll look at the ignition tomorrow. Any other ideas???
