My 05 mdx is having trouble starting at times. I notice that once the car has been running for a while and the engine is shut off, it won't restart until the engine has cooled. Is this a starter problems or some sensor or what? Looking for answers.

Symptoms suggest loss of fuel pressure due to main fuel relay fault. When No-start occurs listen carefully for the fuel pump to turn on, run 2 secs, and go off when keyswitch is first turned to ON.

If you don't hear the fuel pump, the MFR2 (there are 2 fuel rellays) failure is likely.

If you do hear the fuel pump, then ignition fault; keyswitch or security system is more likely, but additional diagnostics req'd to pin down.

good luck
