Dodge Caravan 3.0l

Bad fuel delivery or possibly ignition coils or spark plugs going bad

Your problem is almost never jumped timing. Won't start or even try to start with starter fluid? It probably lost spark (ignition). Do as boaauto says and check for spark on a plug wire. Look for a sharp blue spark. If none on that plug wire, try one more. Orange or intermittent spark is same problem as no spark. Loss of ignition spark could be due to bad coil, bad ignition coil control module (ICM), bad or missing crank position sensor, or a problem in the pcm (which is least likely possibility).
A cheap spark tester should be purchased for spark testing- that way you stand no chance of getting an electrical shock when testing.

Have you pulled codes to see if anything comes up? check to see if you have primary voltage to coil. engine cranking, if no power to coil. check ignition switch or fuse they may be bad. if all else fails, or there is spark or power to coils. this site will show how to test ignition: www.ehow.com/how_4509361_troubleshoot-ignition-system-dodge-caravan.html good-luck!

Crankshaft senor. This sensor supplies info to the ECM, that inturns sends the info to the ignition module that controls the spark. Check the codes.

Hi,
REMOVAL
Always remove the ignition coil assembly by grasping at the spark plug boot, turning the assembly 1/2 turn and pulling straight back in a steady motion.

• Prior to removing the spark plug, spray compressed air around the coil area and spark plug.
• Remove electrical connector from ignition coil.

On 3.5L engines, it is necessary to loosen the screws by alternating back and forth. Do not lose the spacers under the coil when loosening the screws.

• Remove 2 fasteners from ignition coil.
• Remove ignition coil assembly.
• Remove the spark plug using a quality socket with a rubber or foam insert.
• Inspect the spark plug condition.

INSTALLATION
Always remove the ignition coil assembly by grasping at the spark plug boot, turning the assembly 1/2 turn and pulling straight back in a steady motion.

• To avoid cross threading, start the spark plug into the cylinder head by hand.
• 3.5L engines tighten spark plugs to 28 N·m (20 ft. lbs.) torque, 2.7L engine tighten spark plugs to 17.6 N·m (13 ft. lbs.).
• Install ignition coil assembly onto spark plug.
• Install coil screws and tighten: 2.7L engine to 6.2 N·m (55 in. lbs.), 3.5L engines to 6.7 N·m (60 in. lbs.).
• Connect the electrical connector.

u may have a crank or cam censer problem,,if ecm is not getting signal from the it will not spark,,,need scanner to ck this ,,other wise it will coast a lot,,for part changing ,,,

Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

Sounds like an AUTOMATIC SHUTDOWN (ASD) RELAY problem. Fairly common on the Caravan.
Heres a brief overview of the ASD.
The Powertrain Control Module (PCM) operates the Auto Shutdown (ASD) relay by switching the ground path on and off.
The ASD relay supplies battery voltage to the fuel injectors, electronic ignition coil and the heating elements in the oxygen sensors.
The PCM controls the relay by switching the ground path for the solenoid side of the relay on and off. The PCM turns the ground path off when the ignition switch is in the Off position unless the 02 Heater Monitor test is being run. Refer to On-Board Diagnostics. When the ignition switch is in the On or Crank position, the PCM monitors the crankshaft position sensor and camshaft position sensor signals to determine engine speed and ignition timing (coil dwell). If the PCM does not receive the crankshaft position sensor and camshaft position sensor signals when the ignition switch is in the Run position, it will de-energize the ASD relay.
The ASD relay is located in the Power Distribution Center (PDC). The PDC is located on the driver's side inner fender well Power Distribution Center . A label on the underside of the PDC cover identifies the relays and fuses in the PDC
Check for good ground.
Good luck...i hope this helps, please rate me a fixya.

Remove the Caravan Ignition Coil Step1 Look under the hood for a distributor. The spark plug wires connect into the distributor cap. If you don't see a distributor, you may have a model with a distributorless ignition system. Step2 Find the ignition coil. On a Dodge Caravan, the ignition coil is at the back of the intake manifold. Disconnect the negative battery cable to prevent injury while you work. Step3 Determine whether you need to remove the windshield wiper/motor module assembly. This won't be necessary on all models. Step4 Disengage the connector securing the wiring harness connector to the Dodge Caravan ignition coil. Then, disconnect the ignition wire from the ignition coil. Step5 Use a socket set to remove the mounting bolts. There are upper and lower mounting bolts. Separate the ignition coil from the mounting bracket. Install the New Ignition Coil Step1 Insert the new ignition coil. Mount the Dodge Caravan ignition coil to the mounting bracket. Step2 Attach the mounted assembly to the intake manifold. With a Torque wrench, tighten the fasteners securing the ignition coil to the mounting bracket with 96 inch pounds of torque (10 Nm). Step3 Tighten the bolts that secure the intake manifold to the bracket with 115 inch pounds of torque (13 Nm). Step4 Connect the wire harness and any other parts you removed, including the negative battery cable.
