What is the fuel pressure while you are cranking it over?

When you say you have spark and fuel how did you test for each?

A little squirt of starting fluid in the throttle body will tell you if its spark or fuel. You need a gauge on the fuel rail to see if it actually has fuel. Check fuses to make sure injectors are getting power. You'll have to get a spark tester and take off a coil pack and spark plug lead to see if actually any spark. Then you may have to work your way back to the computer.

After a while, got it to run (although really rough idle) for a couple of minutes. To make a long story short, it was water in the gas. Initially checked for that by doing the gas in a glass test, but didn't see any separation. New gas and some STP and it was quickly back on the road. TV reported others with same issue a couple of days later in this area from the same gas station chain.

Hope this helps and hope ya get it fixed. Did you fix it yet?
