i have bought my daughter a 94 cherokee country. i have read about the #703 injectors where do i get these ? also temp. guage not working all of the other guages are working.

 

Hi and welcome to CF from Tj...The injectors can be found on ebay, craiglist or just PM "Programbo" from this forum. The sending unit could be bad on the motor or the wire may have come off for the temp gauge...Tj

 

Injectors from a neon.

And check on the driver side if the head for a small sensor with 1 wire. Make sure its still plugged in. If it is then unplug the wire and ground it out for a sec with the key in the on position and engine not running.
If the guages moves while the wire is grounded, then replace the sensor. If not then the gauge is bad or you have a break in the wire somewhere

 

Ford injectors also work.
