I put new o2 sensors on my car, as soon as i put them my car started for about 30 seconds and then just died. It cranks now when I try to start it but doesnt start. Any ideas for any solution? Please help asap.

First, pay attention to the section you are posting in.

Next, do you have any OBDII DTC (trouble codes)?

No i dont...

Are you saying that because you have checked for OBDII codes and come up negative or that you have not checked?

If there are no codes (unlikely situation if the car does not start), then start troubleshooting the fuel and ignition working your way back.

Also, as you are new here, I will advise you once about spelling/grammar/punctuation.

Well, I used the OBDII to find out that I have to change both sensors. But I returned it back to where I got it from. I guess I will work get it again and work on the next issue.
Thank you

Bad o2 sensors will not keep the car from starting. You either messed something up during the install or a new issue has come up.

Did you use OEM style o2 sensors or the bosch style that has you wire them up yourself?

Check your wiring if you wired them up yourself as you may have burned the ground leg in the ecu by swapping the ground with power wire from the heater.

Just a thought.
