Default no start problem

I replaced my TPS and set the voltage at .99. I started the car and let it run for about 2 minutes. It gradually started running worse and then missing. It finally went dead and now it won't start. It is firing, the fuel pump is coming on when I turn the key. I even put the old TPS back on and tried unplugging it. Still wont start. I'm getting about ready to slap acarb on it and forget it.

Default RE: no start problem

The fuel pump might be working, but is it producing the required pressure ?...... Spark present at the coil ?.... if you spray some carb cleaner down the TB bore, will it start and stall?....

it is firing at the coil and yes she will run as long as i am spraying the carb cleaner to her. Going to get a noid light tomorrow to see if the injectors are firing. If they are it looks like its time to pull the fuel filter and see if im getting gas there. I'll keep you posted. Thanks alot!
