Car Not Starting 911 Crankshaft Code
Alright so I would really like some help here guys. I am a diesel guy but not stupid when it comes to gas engines.
My gf's car (2005 cobalt lt 4dr AT bone stock 2.2) stopped running in mickey d's drive through yesterday. I was at work so a friend who is a diesel mec at a heavy truck shop and was a ford tech came to see if he could help. When he got there the car started fine for him 10-15 times and then would not. He pulled the codes and got the p0340. So after work in the parking while it poured rain I changed the crankshaft sensor. The car then started fine and ran home. I started it 10-15 times with no problem ran it the the rev limter and let it idle. I drove it home and parked it. After an hour I went to go start it nothing. I would crank but not fire. Pulled codes again and again got p0340. When I got up after taking her to work I tried to start the car it fired with no problem idled 5-6min and stalled would not refire. I then changed the plugs upon doing so I found the #3 plug to be loose and brown. I put new ac delco plugs in and it would not fire. I pulled the new plugs after cranking and found them to be damp and smell like fuel. I dried them off and put them back in still nothing. I know it should have a relearn done but would it fire sometimes and not others if all it needed was a relearn? I have not grounded the plugs to see if it is getting spark as I am home alone and have nobody to help me right now. ANY ideas would help so much guys. Thanks alot.
