First off, let me lay down what is happening and what I have done so far. For some time now my TB has been a little difficult to start. I ran the codes on it and the O2 sensor and something concerning the throttle body was called out. At the time i couldn't do anything about it. Here about a week ago on a Friday, the TB decided to be a real pain to start and when it did, it ran rough then died and stayed dead. Now what I get is the engine turning and sputtering as if it is trying to start. I smell fuel and I hear the fuel pump priming. In the last year I have changed out the fuel pump, it went out shortly after the sending unit portion stopped working. After that I put in new spark plugs, AC Delco's, and after having a diagnostic ran on the TB, the camshaft postion sensor. Not much improvement but the vehicle was operable. Now, since then vehicle has stopped running, I replaced the crankshaft position sensor (had a new one given to me when a friend sold his TB), and also checked if i was getting spark from the coil packs(yes I have spark.). I also pulled and cleaned the crap out of my throttle body, damn that thing was filthy. Now I am at an impass, I know not what to do and after searching through the forums I decided to seek advice directly. I really don't want to go to a garage and have this looked at because I probably couldn't afford them anyway. Please help. BTW, I do try to stay away from the 10% ethanol gas but don't always win that fight. If it would help, I could upload a video of me trying to start the vehicle, just need to find my camcorder. Again, please help.
