SOURCE: wont start has fuel and has spark

RC ralston
Your problem is a leak in the cpi pletium most likely the pressure line has a leak
had same problem with mine $45.00 PRESSURE LINE KIT AND $15.00 GASKET FOR PLETIUM and 2 hours labor problem sovled.
You can remove vortec cover and remove air regulator to look inside pletium. I had gas vapor on driver side . that is where fuel lines are. fuel regulator is on passenger side. turn key on and look in hole and see where fuel is spraying. taking pletium off you can again turn key on and make sure where fuel is coming from.

i want you to get OBD trouble codes from your computer. then post them on here. im sure it will hold clues to what the problem is...Various auto part stores will do this service for free in hopes you will buy parts from them...but call them first and make sure. parts to look at Idle Air Control (IAC) Valve...it acts like a choke with modern engines. also the Coolant temp sensor is associated with this as well. Second is the Mass Air Flow (MAF) Sensor. and last one is your Manifold Absolute Pressure (MAP) Sensor . lastly it could be the Throttle position sensor (TPS).. all these can be detected on your computer within the car. although the the numbered codes will be labeled with abreviations like MAP Sensor or IAC valve. also you can manually test all these sensors at home with a regular voltage tester and reading some online info...just search " How to test a MAP sensor" almost all sensors have very similar readings from car to car, so its pretty generic. hope this helps

Do you know if the plugs were changed, a bad or broken plug will also cause rough idle and slow acceleration?

SOURCE: Service engine soon light is flashing

When the light comes on without flashing, it just means an emissions problem, when it starts to flash it has become more serious. I suspect that there was an error putting the plugs and or wires. That computer can determine if there is a misfire and it will put out a P040X, code where X represents which cylinder is the problem. This will help you not have to take each one apart. If there are more than one, check each number.

Ex. P0401 means there is misfire on cylinder number 1

P0400 is a random misfire detected.

If you take it to an Advance or Autozone they will usually scan if for free.

By the way, if you used cheap plugs instead of platinum plugs that could do it too.

Hope this helps.

I have a p2323 code and replaced the spark plugs. I pulled the battery cable and after a week the code came back. What could be causing this.


P2323 Dodge - Ignition Coil Secondary Number 8 Circuit Condition - Faulty spark plug or coil boot
- Faulty Ignition Coil 8
- Ignition Coil 8 harness is open or shorted
- Ignition Coil 8 circuit poor electrical connection
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine may be running rough

P2323 Dodge Description
The ignition system is controlled by the Powertrain Control Module (PCM) on all engines. Each cylinder is equipped with 1 dual-output coil. Meaning one coil mounts directly over one of the dual spark plugs for 1 high-voltage output.
Battery voltage is supplied to all of the ignition coils positive terminals from the ASD relay. If the PCM does not see a signal from the crankshaft and camshaft sensors (indicating the ignition key is ON but the engine is not running), it will shut down the ASD circuit.
Base ignition timing is not adjustable. By controlling the coil ground circuits, the PCM is able to set the base timing and adjust the ignition timing advance. This is done to meet changing engine operating conditions.
The PCM adjusts ignition timing based on inputs it receives from:
- The engine coolant temperature sensor
- The crankshaft position sensor (engine speed)
- The camshaft position sensor (crankshaft position)
- The manifold absolute pressure (MAP) sensor
- The throttle position sensor
- Transmission gear selection

Turn on the key and listen by the fuel tank for the fuel pump to hum. A common problem is low fuel pressure. It will build pressure when the key is turned, use that fuel, and then the pressure drops. Kind of like when you're using a squirt gun that's getting empty.

Amke sure that any ground wire has not broken off on the wiring harness. There should be a grooup of wires that ground at the belhousing close to the starter. One of them is the ground for the ignition/coil.
