new to this whole deal and needin advice.i have 86 zuk with 94 -1.6 swap it keeps shorting out ecm and the only code is for engine coolant sensor.i put in a new sensor and 2 different ecms? any one got any ideas ?

Try a search for engine wiring diagram at acks's FAQ.  Unfortunately, I have discovered that the six different engine types have the same injection type in the link heading! 

OOPS! I need to fix that tonight!

Select one of the two 1.6 engines type that you have. One of those is your wiring diagram.

Compare it to what you have - making SURE that the grounds are all tight.

Hope that this helps!
