Exclamation Please help need car to go to work.

I just got codes from my dash and retrieved numbers
= 11,12,21,21,11,54,=55.
Now if I'm not getting a signal from the crank shaft sensor would that make the car not start?
I just rebuild my ax-5 transmission found out I put the wrong flywheel in and had to remove it and put back the original flywheel. I went to take it for a test drive and it started sputtering and died. I thought it was out of fuel so went to gas station put in gas now it won't start so I checked the codes. I thought it was the fuel pump but I can hear it buzzing and there is fuel coming from the fuel rail. Please help.

Yeah, if you aren't getting a signal from the crankshaft sensor , your computer will not allow your Jeep to start... It senses where your flywheel is with respect to your motor.
Are you sure that the sensor was put back correctly? I believe it would be located on the bellhousing... Near the top...?

So when you removed and put the transmission back in when swapping the flywheel, you may not have remembered to get it connected or possibly just not correctly...?

Not trying to be harsh - just tryin' to help!

When I dropped the trany I never took the sensor out of the bell housing just unplugged it. I have a spare one in my work shop guess I'll be under it again today and be replacing it see how it goes.

This may be a silly question but did you plug it back in?

I had my 16 year old son do it, but I double check it just to make sure he connected it. I found my spare one put it in and it started up, took it for a ride in the neighborhood and it seemed fine. I have a 60 mile commute to work and there is nothing like sitting on the side of the road waiting to be towed home. So tomorrow I will take it for a nice long ride before my Tuesday commute to work. I want to thank you wranglin4life and keymo for your help.

Haha! Don't you hate it when crap just goes out on you out of no where?!

Glad you got it figured out though - and lucky you had a spare laying around! Hopefully she holds up for you! It would definitely suck to break down on your way to work - or when you need to be leaving for work... Good luck, man!
