Ferm, I need Jeep help asap

[spareparts]

never mind, I figured it out, crank position sensor shorted to ground, low reference voltage, check engine light would not come on when key was turned to the on position. Checked for 5v on refernce line, had 1.2 volts, started unplugging sensors and checking voltage, when I got to the cps, I had 5 v on the reference line.
