Vauxhall cavalier running problem.

96 chevy cavalier running problem.2.2 motor auto?

• first of all i was coming down hwy and the car stalled. Wouldnt start again. Put more gas in. That wasnt the problem. I can hear the fuel pump kick on. I towed it home. Hooked it up to code reader. I got code reader and only code came up was cod. po330? which is crank sensor. Reset the computer. It starts up but has a severe code po300 misfire code. When it starts it mite run smoth for a second then run really rough and sometimes stall. Please help. My girl really needs her car. Thanks. Whats wrong and how do i fix. Thanks everyone.

• Answer:

  change the crank sensor ! but before you take the old 1 off mark around it ! that way you can put the new 1 back in the same place. if you don,t get them on just right it can ruin the damper and the sensor the first time you crank the engine. marking around the old 1 first then the new 1 will be lined up right. that center bolt is very tight in the crank.
