Question about 1994 Dodge Grand Caravan

1 Answer

Engine starts intermittently. Runs fine when it starts, but when it won't start there is NO SPARK coming from the coil. Fuel is present. When not starting the coil input wires measured an erratic 0.6V and GND - did not et to measure when running. I suspect the ignition module, but previous owner said wiggling wires in that area while cranking got him started on occasion. I tried this and got 1 start after an hour of wiggling and exercizing all the connectors, and wiggling same wires while it was running did not cause a stumble. Any other ideas what to check before I buy an ignition module?

You can take the ign module to Auto Zone and have them test it. doesn't cost a dime.

JD JS45 walk behind mover. Starts, runs fine for 5 minutes, then stalls, won't restart till i pull the spark plug and cool the motor, plug down. then same thing starts, runs for 5, stalls.


Probably either a fuel or a spark problem. You need to check for the presence of a good spark immediately the engine stops - by using a spark gap, a spare spark plug or a propriety spark indicator.

If the spark is found to be absent the fault is likely the ignition module but check all connections and the stop switch operation before replacing.

If the spark is present then the fault is probably fuel-related and is the sort of thing a tiny droplet of water in the carb could cause...

Could have a vacuum leak , a problem with the IAC - idle air control motor !
Rough, Unstable, or Incorrect Idle and Stalling
Inspection/Test
Action
DEFINITION: Engine runs unevenly at idle. If severe, the engine or vehicle may shake. Engine idle speed may vary in RPM. Either condition may be severe enough to stall the engine.
Preliminary
?€¢
Refer to Diagnostic System Check - Engine Controls .


?€¢
Refer to Intermittent Conditions before starting.


?€¢
Search for bulletins.


?€¢
Observe the owners driving habits.

Fuel System
?€¢
Test the fuel system circuits for proper operation. Refer to Fuel Pump Electrical Circuit Diagnosis .


?€¢
Test for low fuel pressure. Refer to Fuel System Diagnosis .


?€¢
Test for faulty fuel injectors. Refer to Fuel Injector Balance Test with Special Tool , Fuel Injector Balance Test with Tech 2 , Fuel Injector Solenoid Coil Test test procedures.


?€¢
Inspect for fuel contamination. Refer to Alcohol/Contaminants-in-Fuel Diagnosis .


?€¢
Inspect for fuel in the pressure regulator vacuum hose.


?€¢
Ensure each injector harness is connected to the correct injector/cylinder.


?€¢
Inspect for any items which may cause an engine to run rich, long term fuel trim is significantly in the negative range. Refer to Diagnostic Aids for DTC P0172 .


?€¢
Inspect for any items which may cause an engine to run lean, long term fuel trim is significantly in the positive range. Refer to Diagnostic Aids for DTC P0171 .

Sensor/System
?€¢
Test for conditions which cause an incorrect idle speed.


-
Throttle body tampering, excessive deposits, or damage--Refer to Fuel System Description .


-
Restricted air intake system


-
Large vacuum leak


?€¢
Inspect the air intake ducts for being collapsed, damaged areas, looseness, improper installation, or leaking especially between the MAF sensor and the throttle body.


?€¢
Inspect crankcase ventilation valve for proper operation.


?€¢
Inspect the throttle position (TP) sensor and related wiring. Refer to DTC P0123 .


?€¢
Monitor the 24X crank sensor and the CMP sensor signal present parameters on the scan tool. If both are not responding, test the sensor feed circuit. Both sensors use a separate feed circuit but are internally connected to power. Test all CKP sensor A and CMP sensor circuits for intermittents. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.


?€¢
Monitor the 3X parameter on the scan tool. If the 3X is not responding, inspect the CKP sensor B and circuits for intermittents. Inspect the ignition control (IC) circuit, IC timing control circuit, low resolution engine speed signal circuit and the low reference circuit for intermittents. If these circuits become open, or shorted, they may not set a diagnostic trouble code (DTC) immediately, but are capable of causing driveability complaints. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.


?€¢
Test the exhaust gas recirculation (EGR) system for proper operation. Refer to Exhaust Gas Recirculation (EGR) System Description .


?€¢
Inspect the Transaxle Range Switch input with the vehicle in drive and the gear selector in drive or overdrive


Ignition System
?€¢
Inspect for proper ignition voltage output using the following steps:


1.
Attach the J 26792 Spark Tester to engine ground.


2.
Connect the spark plug end of the spark plug wire to the J 26792 . Leave the other end of the spark plug wire connected to the coil being tested.


3.
Connect the spark plug end of the companion spark plug wire to ground. The companion spark plug wire is the wire attached to the corresponding coil tower.


4.
Crank the engine while observing the J 26792 . A spark should be observed.


5.
Repeat the above steps for each coil.


?€¢
If spark is not present at the coils, inspect for the following conditions:


-
Coils--Cracks, carbon tracking/arcing, or a resistance value outside the specified range

Coil Resistance
5000-8000 ohms (5K-8K ohms)
-
Spark plug wires--Signs of arcing, cross firing, cracks, carbon tracking, plug boot damage, pinched, improper routing, or a resistance value outside the specified range

Spark Plug Wire Resistance
9 686 ohms per meter (3,000 ohms per foot)
Important: : Spraying the secondary ignition wires with a light mist of water may help locate an intermittent problem. Ignition voltage will arc to ground when a secondary component is faulty.


-
Defective ignition module


-
Ignition system wiring--Loose ignition module feed or ground connection, or damaged system wiring


?€¢
Remove spark plugs and inspect for the following conditions:


-
Fouled plugs


-
Cracks


-
Wear


-
Improper gap


-
Burned or damaged electrodes


-
Improper heat range or reach


?€¢
If spark plugs are gas or oil fouled, the cause of the fouling must be determined before replacing the spark plugs. Refer to Spark Plug Inspection .

Fuel pump


Testing of the fuel and ignition systems is in order. Intermittent problems need testing when the problem is present, otherwise it won't help find the problem.
I would start by checking for spark on a spark plug wire (or two or three plug wires, in case it may be a bad coil), during those times when it won't start. You need to see a blue, snapping spark to verify ignition system is working.
To check the fuel system, have the fuel pressure checked, and the injector circuit checked. Good that you hear the pump, but you don't know if fuel pressure is correct, or if fuel is getting into the cylinders. One short test is to spray starting fluid or carb cleaner into the intake while engine is cranking. If engine fires up for a few seconds, you know it is a gas related problem.
If ignition system is the intermittent problem, could be failing coil or coils, ignition module, crank position sensor, even the computer, or a wiring problem like a bad connection. Testing of each component will be required, or you could start throwing new parts at it, like many people do, until you find the bad part. Find a reputable mechanic-there still are a few, lol.

===========





Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

91 camero rs starts runs 10-15mins and dies . Will not start again til cold a


Hello Ryan, start by checking the battery terminals and cables. The cables on these Camaros are known to corrode and cause intermittent starting problems. The next time it stalls & won't start, check for spark. If no spark, the ignition module, pickup coil, or ignition coil is likely the problem. This model did not have a crank sensor. If spark is present, check for fuel pressure. I hope this information is helpful.
