Try your fuel filter first, then check for fuel at fuel rail to make sure pump is functioning properly if at all,bleed off any air trapped in rail thru valve... get back to me if this isn't the problem and we will procede with next steps...

    sorry I didn't get back to you sooner. Id like you to try this to help me help you. turn the key to the on (running position) wait about a minute then continue to turn the key to the starting position (without turning key back off). A problem like this can be hard to track down without a computer diagnostic. Eliminate relays sticking and ignition switch operation as a possible cause. Is you mass air sensor clean as well as your throttle body. I would check connections and immpedance (resistance value) of all sensors on throttle bobody/intakemanifold; check all vacuun hoses; Is there a cold start valve on your particular motor?

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.
