Having problems with your 2001 Jeep Wrangler ?

Jeep trouble code 320 and 743

\015 Will be driving and motor will cut off. Try to crank but it just cranks no fire up until i used jumper cables. The lights will still be on but flicker a little. I fired it up unhooked the battery and it idle fine besides voltage gauge moved up and down some. This has happened several times finally replaced fuel pump relay and CSP sensor it ran fine for a day and did it again. Any suggestions ? and will the 743 code shut the motor off ? it says its a trans code . Thanks\015

Answers :

One problem at a time please. Let's get the engine running All the time! First, it seems that the battery is weak, perhaps old and past its prime (thus the jumper cables worked). Or, maybe you just need to clean off the battery terminals on the battery and the connecting cables. When did you replace the plugs, wiring harness, distributor cap and rotor last? Perhaps just cleaning them up will do the trick. Also, check that the grounding cables all over the engine compartment are clean and tight.

P0305, P0135, P0351, P0352, P0353. 3 of them are ignition coil circuit codes (coils A, B, and C), one is an o2 sensor heater malfunction (Bank 1 Sensor 1), and one is a cylinder 5 misfire. All seeming to happen instantly and at the same time. Having them all happen simultaneously like this leads me to believe it's either a bad PCM, or maybe something upstream, such as bad fuel pump, is making eve
