Motor wont start after swap. What to check? I swaped a 98' LS1 in to my Jeep Wrangler and I'm trying to start it for the first time.
It will crank but will not fire. I'm getting fuel but no spark. I have power to the coil packs
I borrowed a Snap-On scaner from a guy and the only code it gives is "P0452 EVAP system Press SNSR signal Low"
I've never used a scanner before but everything I saw said "OK to drive
" or something like that.
I assume that my computer is ok because the scanner reads the codes.
While i'm cranking the scanner shows 150-170 rpm. is this fast enough? someone told me that it need 400rpm before it will send spark is this true?
What else can I check?
thanks
