car won't start up some times.
 

I have a lightly modded 88 Civic HB. I was driving the car pretty hard the other night, pulled over to meet up with a friend, tried starting car to follow him to his house but it wouldn't start. Went with him, came back later (about 40 mins), car started right up.

Drove car to Sacramento that night. All was fine, left it running when filling with gas or stopping to drain the main vain.

Took car to Walmart, drove a little harder then normal driving, parked car and went in store. Came out after about 20 mins, car wouldn't start. returned later that night when it was cooler, car started right up.

Took car to hockey last night, same driving style. Had about a 50 min draft. came back to car, wouldn't startup. Turned key off, ran through all gears (it's an auto), started up just fine.

I'm not sure what the issue is. Might be my started but wanted some opinions first. Sorry for the long post.

I have that problem too, though not as frequent. I'm looking at my ignition system as a possible culprit. plug wires, distributer, rotor, cap, starter. I'm going to wait till it gets real frequent and then start replacing things.

^^ I've been asking all the guys at honda-tech, they are all leaning towards the shifter switch. Is your car manual or auto.

does it crank ? or it's just dead ? if it cranks but it doesn't start it's the main relay. mine had the same problem. it could be the shifter switch (auto), and that is a biatch to fix, or like $90 to replace

it won't crank period, you just hear the fuel relay click (which is new) when i hit ign on, then when i turn the key to start it, nothing.

yeah it sounds to me like a transaxle position switch too.

Trans axle what?

Was in Newport, pulled over, put some gas in car, go to turn car on, NOTHING. tried shifter in all different positions, nothing. Pushed car to shady area, turned key to on and fans in engine bay engaged. Let the fans run till they stopped by themselves. Tried car, started.

So WTF. It has to be something to do with heat. I can't figure it out.
