I have a 1995 dodge neon,sohc, mistakenly i've put the battery wires wrong,and now the car doesn't want to start, i've changed the coil, check all the fuses,the only thing i know,that the wires from the coil to the ecu doesn't have spark, can any one help me out with this?

 

So put the battery cables on correctly. Or do you knot know where they go?

 

Don’t know if dodge built any reverse polarity protection into any of its electronics.
Once you have the battery hooked up right check to see if the PCM will read out codes. If it does (even just the 55 code) then you may have gotten away lucky and not fried the PCM. This is no guaranty that the PCM is total intact but is a good sign. It’s also possible that some of the sensors could have been damaged, the crankshaft and camshaft sensors use hall effect semiconductors and may be damaged. The dash cluster may have also been damaged but should not prevent startup.
