2G rebuilt motor will start but wont stay running??

[clemonte87]

ok i recently rebuilt this motor for my 97 gst. i got everything hooked up and all fluids in. i did install a 1g cas, im getting spark & fuel. it will crank and start up, but only for about 3 - 5 seconds and then dies. if i try to give it gas it dies also. i dont know what else to do with it to keep it running. any and all help will be much appreciated!!

I would first try and see if you can keep it running by spraying ether sparingly through a small vac line like the fpr port. If it continues to run we know its a fuel issue.

Is there any code being thrown?
