Ok think I found one of my problems, If I take the wire off the injector on cylinder 'one" engine runs same idle doesn't change, with or without wires idles same(wire directly to injector) is gettin power within in correct range, ok if i put wires back on injector 1 and pull the injector off cylinder 2 the car stumbles, until i put wires back, does the same with 3 and 4, I am assuming these means the injector in cylinder one isn't working? how hard is it to change? and what parts do I need to buy to do it, does anybody have a diagram or some insight? Thanks! By the way pulled the plug on cylinder 1 and tested to see if gettin spark and it is.

If the check engine light cones on and stays on (instead of going out after 2 seconds) when you turn key on but don't start, that is usually the main relay. You should also hear the main relay click on and off.
If you get the proper CEL and the relay clicks, take the bottom cushion of the back seat out and find the fuel pump wire (I think it is green and yellow). If you get battery voltage on this wire during the priming sequence but the pump doesn't run, the pump is probably bad (or a bad connection or bad ground near the pump).
