i noticed this intermittent problem about a year ago. when the car heats up, (especially on a hot day and or if i run it on the freeway) if i turn the car off, it won't immediately start again. the starter turns, just won't start. waiting about 30 minutes or so, the car will start right up.

my first guess was the starter, so i eventually changed it. problem persisted. just recently i noticed when the problem was occurring, i didn't hear the fuel pump priming when i turned the key. then when i finally heard it prime, the car would start right up. i confirmed this a few time already when the problem occurred.

any ideas on what the problem actually is? the fuel pump itself, fuel pump relay, ground wire? i'm going to try and troubleshoot it later, just wanted to see if anyone ever heard of this or had any ideas.

 

Ever find out what's wrong? I have a 91 acura that has the same problem but am too busy to bring it in for repair.

 

I get the same problem but only in peak winter when it's -30 outside.

 

Happen to my civic and it ended up being the coil. Replaced the whole dizzy

 

Thanks for the tip! I'm the original owner and it has 145k so I'd like to keep it running as long as I can.

 

I would tend to blame an ignition issue. Have you pulled the spark plugs yet?

 

I rigged a voltmeter to the fuel pump relay under the passenger kick panel to see if it was sending power when the problem occurred. It does, so my guess it that it may be the fuel pump itself or somewhere near there. I'll rig the voltmeter to the back to see if power reaches the back there.

 

Any progress?
