replaced heater core now no start!
 

ok went over everyhing again and i attached all the wires and harnesses what else could be going on? computer??
its a 95 gt 5.0

?????

got to be something not plugged in right. did you remove the whole dash along with wiring?

re-check all your wiring...you probably left a ground out

Thanks fellas but I figured out the theft light was flashing sooo long story short screw pats (passive anti theft system)

So does this mean its fixed or does it mean its in thief mode and won't start?

that stupid pats, has it ever kept anyone from starting their vehicle OTHER than the owner?

I agree its seems like the wiring issue because sometime when we open the dash then we forgot the plug all the wires by mistake. So you should recheck all the cables and fuses which can be involved in the starting system. It also possible that may be you attached the wrong wiring. Gud luck...

the wiring issues are the only one to annoy and worsten the condition rest all goes fine for this and makes one superb
