Hello all, I have a 1999 Grand Prix GT 3.8 non/supercharged with 167,000 miles on it, I replaced the radiator,starter,waterpump and thermostat. I got this all back together again and for some reason it just will not start. It cranks and I get sputters but will not engage. I know it is getting fuel and it has spark (pulled a spark plug set it on metal and watched it and has a orange spark) and the battery is fully charged. I am thinking it is the crankshaft position sensor but I have no way to test it (the CPS has 4 wires and I dont know which ones to test can use advise on how to do this without a OBD2 scanner) I could use any advise you can throw at me I am getting frustrated and just want it fixed. I thank you in advance...
