Need to know what year the donor engine came from. 99-01 direct swaps. 02-04 into an 01 can be done but more than just plug & play.
Any Codes?

Did the 2000 engine run prior to removal from donor car?
Check engine light / MIL on?
Codes? "Key Dance" will cause odometer to display codes.
(Key on/off/on/off/on)
I would suspect cam or crank sensor issues may be your issue.
Crank sensor (pass side in trans housing) may have been damaged during engine swap if it was not removed. Flex plate teeth could have hit it.
Cam sensor (center front under plenum) also suspect as they tend to fail also.
Maybe swap sensors from engine removed and give it a try.

best i remember they were the same
not sure though that is why i swapped all the sensors and intake over
got it to start once but it only stuttered for a minute then died had to hold gas to the floor for it tom start then
i'm thinking something with the fuel because it will stay running as long as you spray starter fluid or gas in the breather but i don't know that is why i'm asking for help
