Time for a code check.

Posted on Nov 26, 2013

Testimonial: "Code was P1389, I had accidentally short cranked it over the weekend, (had shoulder surgery so had to start with left hand) and my hand slipped off the key so I think I threw the starter off. After a few times of starting and stopping it seems to have gotten lined back up. This morning, where it was very cold out again it started up just fine and the engine light is off. So hope this is the end of this problem..."

Are you getting spark from coil wire when cranking? If so, check the cap & rotor. If not, the most common failure is the crank sensor. If you have a 4,0, you can find it on the drivers side of the bellhousing, in line with the flywheel, just where it's annoying to work on. There is a test you can make, but I don't have the specific test values or the correct terminals to check. (you can find that info in any half decent manual.
Good luck

SOURCE: Hard starting when cold ( engine cranks normally )

see if your engine has a ECT sensor (temp sensor that delivers information to your ECM) they are installed on the intake side of the cylinder head, it usually has 2 cables, have it checked replace if necesary

Cold starting


Most common reason for no start cold with a lack of fuel is the fuel pump relay or the check valve in the pump.
The fuel line should have some pressure it it after sitting overnight. If not, the check valve in the pump may have let fuel flow back into the tank. It would take a few minutes of cranking to get it started.
Also, if the fuel pump relay is not working, the pump would not get power until the engine has oil pressure.

There are several things that few people know about starting cars in cold weather. 1. Check your battery to make sure it is not rusted, leaking, and has a charge 2. Jump start your battery with another car, even if you believe the battery is good, this often times will still start your car. 3. If your engine is cold, and you have an older car, ensure to get your fuel lines to the engine flushed or have fuel injection service performed 4. The engine tends to warp the same way wood does during the extreme cold, do not be afraid to continue trying to warm up the engine by constant cranks with it is cold out. Your not going to hurt the car, the worse that could happen is too much fuel will enter the carborator and cause flooding in the system to occur. Wait 20 minutes if this happens and start to crank again 5. Bad spark plugs are a major reason why many cars take a very long time to start 6. Please have your spark plugs removed and exchanged for new ones. Over time, spark plugs become fowled and prevent the car from starting even thou you hear cranking!!!

You need to check, when the jeep is cold, if the check engine light comes on when you turn the ignition switch to on, before cranking the engine. If that light does not light up on the dash immediately, then the jeep won't start until it does, which can be as short as a few minutes to as long as 20 minutes. That would be a classic sign of a bad ecu, slowly getting worse, that needs repair. Check it out and post back here in this same thread with your findings.
