1992 Honda Prelude Car sometimes wont start

If the engine's condition is in tip top shape-do below to determine if its fuel or spark problem that's if its cranking over and refuses to start

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil,distributor pick-up coil, ignition control module, cam and crank sensors-

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time

Hi rizzoo8,

My guess is the main relay is faulty.

This usually happens when the car sits out in the hot sun. It will turn over but wont kick on. Sometimes it sounds like its gonna start but then it boggs down and dies. It seems like heat from the engine comes into the cab too...?? If i have it in the garage or in a shaded area it starts. I've heard that it could be the fuel pump, so i replaced that and the fuel filter a few years ago. I still have had the same results. In 07 i replaced the 2.3L w/ a h22a vtec and that didnt help either.. Any ideas???[/quote:46c3e462c9]
