Have you check the fuel system?

If you have spark getting to the spark plugs then it is possible that your fuel delivery is faulty.

Check that you got fuel at the main injector fuel rail.
If not then check that you have power supply to the fuel pump.

If you have power to the fuel pump then check that you have fuel getting to the fuel filter etc.

Let me know how you get on, if you ned more information.

I keep getting a code P0340.Chrysler has reprogrammed the PCM for a long start issue.I cant seem to get anywhere with it.

P0340 - Camshaft Position Sensor Circuit Malfunction
This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

Symptoms can include:
Hard starting or no start
Rough running / misfiring
Loss of engine power

Causes: A code P0340 could mean one or more of the following has happened:
a wire or connector in the circuit could be grounded/shorted/broken
the camshaft position sensor may have failed
the PCM may have failed
there exists an open circuit
the crankshaft position sensor may have failed

Possible Solutions: With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
Visually inspect all the wiring and connectors in the circuit
Check for continuity in the circuit wiring
Check the operation (voltage) of the camshaft position sensor
Replace the camshaft position sensor as required
Check the crankshaft position circuit as well
Replace circuit wiring and/or connectors as required
Diagnose/replace the PCM as required

Hope helps.

SNSR Fuse allways short when i put the key at On...or try to start the engine... 2.0l Standard

Hi there,

You don't actually mention whether your engine STARTS?

The SNSR fuse covers the following components:

- Oxygen (HO2) Sensor
- Camshaft position sensor
- Crankshaft position sensor
- Idle Speed Con Actuator

So, there is obviously a problem in one (or more) of these circuits.

Due to the new type OBII Diagnostics on the Tiburon, you will need to take the vehicle to your nearest Hyundai Service dealer and have your CODES scanned from your vehicle's computer. This will determine where the actual fault/s are.

However, if you're technically inclined, I can show you one possible way to 'manually' extract the diagnostic codes from your vehicle's computer, by accessing the Data Connector under the dashboard (above either driver or passenger knee).

The data connector looks something like this:


Let me know if you'd like to try and solve yourself, and I'll provide you with further instructions.

Today after work my '04 Tiburon took like 6 trys to start? any suggestions or potential issues this is commenly related to?

try for temp use, turn key to on position and wait 3sec then try to start. You might have a fuel injector leaking pressure while system is shut off. There is also a fuel pressure regulator that is supposed to work as a check valve. If it leaks down psi then it could cause hard to start. By turning key and waiting the fuel pump primes for intial start.
