Help
Got a 91 RS, 305, TBI, Just replaced O2 sensor, Spark plugs, wires, cap, rotor, the nice tune up stuff. Removed the Smog pump and all the lines and hoses, and capped the exhaust. All the wires are in the proper places. Does removing the Air Pump and disconnecting the two sensors cause it not to start? Now it won't start, any help would be awesome. Thanks

Re: Help
OK, the car has fire, has fuel, and turns over. I changed the TPS, and the fuel pressure reg. still no start. Ran the Codes all I got was 12 for about 6 to 7 times in a row. The sensors in the air chamber that was hook to the smog pump, would that cause it not to start? I'm lost. Help

Re: Help
go back and check all of your recently replaced tune-up Parts... you have made a mistake some where...
OH the AIR pump has NOTHING to do with it AT ALL...
