Wont start, not battery, not fuel pump, no spark turns over
Hi Tammy, does you vehicle have any lights lit on the Dash, check engine light etc... You need to see if you have battery + voltage at the coils , an to see if the PCM is turning them on an off ! PCM - is the engine control module . An see if there is an input signal from the crankshaft position sensor . It would also be good to hook-up a scan tool to see if it can communicate with the PCM . Mite have a shorted 5volt reference circuit . Do you have 2.4 L 4 cylinder or 3.0L V-6 ? IF you have the 2.4 L 4 cylinder you need to Check for B+ on the Black/White wire at pin 4 in the connector at the ignition failure sensor with the key on. Jumper the Black/White wire at pin 4 to the wire at pin 3 at the ignition failure sensor connector. If spark is present now, replace the ignition failure sensor. Unplug the Crankshaft Position (CKP) sensor connector. Check for 5 volts on the Green/Red wire. Reconnect the CKP sensor connector. Check the Black wire for a good ground. Check for B+ on the Red wire. If the Green/Red wire goes higher when connected to the sensor and cranking the engine, the CKP sensor is faulty. Let me know if you have questions, thanks.
