Has it overheated lately?
My wife overheated our Galant and it just stopped working, it cranks but that's it.
I pulled the sparkplugs and found them wrapped in a gewey jelly like substance. Like an oil/antifreeze combo.
I am going to replace the entire motor for $1000 as taking it to the mechanics to theorize and practice may cost more.

SOURCE: Starts fine when cold, after running dies on idle then wont start

Sounds like the fuel filter is dirty and needing to be changed. It's cheap and easy to swap out.

Blair, I would take a look at he TPS (throttle position sensor) located on the throttle body. In other words, it sounds as thought sensor when heated is changing its value to "open" or "shorted".
If the car starts OK when cold, use a hair dryer to heat the TPS when the engine is cold to see if you can duplicate the problem.
Also is the a service engine light on? Codes?
If you have a "digital volt/ohm meter" available you can read the variable resistance of the sensor when the problem occurrs to determine if the sensor is defective.

SOURCE: After starting car check engine

Diagnosis must begin with scanning your Engine Control Module to find out why it has turned the light on. The car may seem to be running OK, but there is probably a problem that is causing you to use excessive fuel and/or is threatening to destroy some high dollar parts like your catalytic converter.

SOURCE: 2006 f250 diesel....crank and crank

The first thought that comes to mind is a high pressure oil leak. The injectors have a snap ring on top that sometimes becomes detached and it will create these symptoms.

When you depress the brake it sends a signal to the PCM (Powertrain Control Module) and the PCM increases the idle because it predicts you are about to shift into gear. If the truck has a high pressure leak inside the engine it will have a hard time building pressure initially and once the oil warms and thins out the High Pressure Oil Pump cannot hold the pressure and the oil leaks faster because it is thinner.

You may have a leak around the pump area which is under the turbo also. The IPR which is the regulator that controls the oil pressure may also be bad. It is directly under the turbo as well. The IPR is located under the turbo on the High Pressure Oil Pump cover. You stated the seals were leaking on the IPR itself? If the orings are damaged or if the screen in the end of it is collapsed or even punched through with a small hole it will need replaced. Screen damage is usually a sign of debris entering it from either dirt from a previous repair or something is coming apart inside.

Make certain you have clean oil and fuel filters. Yor may want to check fuel pressure as well. It should be somewhere around 55psi on acceleration.

Additionally, I suggest check for voltage at the connector on the fuel pump. The pump is mounted in the filter housing on the frame and the connector is at the front of it. The pink and black wire should have 12 volts with the key on for about 30 seconds. If the pump has voltage but is not running, then your pump has failed. If there is no voltage then check fuse 2.40 in the central junction box. This is the fuse that feeds the inertia switch through the fuel pump relay. I have included a fuse box layout and a wiring diagram (click over images for zoom)...

Additionally, will need to scanned the PCM to know if some fault code is stored there.

Keep us updated.

I changed the 02 Sensors on my 03 Mitsubishi Galant do I need to reset anything on my car? It turns on fine but idles low when put in gear and shuts off.


Its a hot start issue.

Can be related to low fuel pressure or problem with crank sensor.


Also it can be weak battery or starter.


But possibilities are to be inspected to confirm what exactly it is.------

2002 mitsubishi galant runs fine 15 min. wont start wait 20min it will start


As with any no start issue, you will need to figure out if you are dealing with a no spark or no fuel pressure problem to proceed.
I would check those things the next time it will not start.
Could be a relay, coil, sensor, or other component.

COLD START ISSUES- WHEN COLD WONT START WITHOUT PUTTING FOOT ON THROTTLE, OTHERWISE RUNS GREAT


Most cars have a "cold start" sequence that is activated by a heat sensor. There may be 2 sensors with 1 running the temperature gauge or light, and the other operating the feedback to the "cold start circuit".
Go to a good autoparts store and see what parts they have for this circuit. Also check around the throttle for any solenoid which looks like it might step up the idle. Usually, if you have fuel injectors you will not have a step-up Solenoid.

Have a 2002 galant with 2.4 cold it turns on good it will run for 20 min. but after that it will shake and turns off i replaced crank sensor and coils but it still has the same thing.


If you remove the gas cap, does it still die after 20 minutes? If so, then there is likely an evaporative emission system problem, or a fuel pump problem.

Could be a dirty fuel filter. Could be an ECU problem. Any error codes ?
