Hey guys n gals hoping you can help some scum bag stole my missus keys, so I did what most other would do
New key barrel keys ecu and bem. Now the car started but didn't have enough battery to crank, I put my optima
On it and now it's not starting relays under the dash click and the (!) light comes up on the dash but won't start!

Update:::::: disconcert the batter for 5 mins and put it back on car cranks won't start (base) appears on the dash and fuel pump primes any ideas?

does interior light work
does it have a smartshield light or smartlock if so does it go out when key turned to reds
are the replaced components from same vehicle
do you have spark and or injection pulse

Found the issue bem n ect were from scurries one but mines an early 99 model and Dose not have a key reader, our back my original bem and ecu and only kept the new barrel still have to get remote programmed tho all good
