CEL code
P1495 Leak Detect pump ckt.
Could this be because i blocked off my EGR? or Because i got the wrong PCM?
Heres my setup so far...
97 DOHC MTX
SRT4 turbo w/mani
SRT4 Actuator
Non-turbo 2.4 injectors
DOHC Head on SOHC Block
98 DOHC MTX PCM (junk yard)***
ATX to MTX

If you blocked off the EGR, and you have a non-performance PCM (like the MOPAR Performance PCM), then your CEL will be on all the time and you cannot reset it as it will come right back on almost immediately. Sooo.....
Either ignore the CEL, reconnect the EGR, or get a performance PCM that does not care about an EGR.

Thanks for the info 
but maybe i wrote my problem wrong... i dont have an egr code at all. I have a p1495 and p1494 code. Leak detect pump, is this a california emissions thing or something else, cause i am clue less as to where it might be.

It has nothing to do with your EGR. This is a typical problem after doing the ATX to MTX swap. You need to find an evap canister with a Leak Detection Pump. The "new" PCM is looking for a signal from the LDP. You have an electrical connector by the evap canister and you will also need the extra vacuum line which connects to the blocked off vacuum line by the evap solenoid. The evap canister is behind the front bumper cover and under the splash shield on the passenger side.
