Hey all. For those who helped with my sterio question, thanx for the help.

New problem. This time, a 2002 blazer 2wd (although that may not matter). Simply put, the engine will not start. I spent a good 5 hours on it and I have know it has a good spark, it gets air, and it gets fuel. No fuses are bad and all relays are working. I have harrowed it down to one of two things and am asking for a second opinion hoping for the better of the two.

First off, this vehicle has a half tank of gas, so if that is the case it wont be as bad as a full tank. So saying, i'm thinking it has a bad tank of gas. I personally know how bad these trucks can run, if at all, with bad gas. So if this is the case. is there a easier way to get the gas out of the tank by other means than removing the tank to drain it that way, as per hanes manual.

My second thought is, possibly timing chain related. Maybe skipped a tooth or broke all togeather. If this is the case my friends engine is mostlikely F'd. by wich case i probably have a good doner car for spares and upgrade parts. I think this because as u turn the engine over, you can hear it and see it back fire though the throttle body

Any extra thoughts would be very nice to hear. I'm betting and really hoping that its the fuel problem.
