O2 wires where cut. I pushed on exhaust and harness side of o2 wires sparked and the jeep shut off. I now have. Zero spark.
The spark happened when the harness side of the 02 wires touched the heat shield the Jeep cut off . Immediately. I started trying. To. Figure it out. Other symptoms are. No voltage guage, fuel pump seems to run non stop. 3.7 volts to coil. Asd relay terminal 16 has 4.2 volts key on and 18 has 10/12 volts key on both loose voltage when key is off. I tried a different pcm and all symptoms remain. I changed cps sensor and symptoms remained. Im baffled and my obd2 port has never worked. Theres no check engine light. Im a ase tech but very weak electrically. Im so confused
have the same problem?
