Honda 1997 my car while driving the engine shut off.

code 15 is ignition output signal, an electrical problem. The engine computer sees no spark signals coming from the igniter. This is a good job for a Honda mechanic who isn't afraid of electronics.

Clutch plate and pressure plate seem to be too weak to pull the car. To test the clutch plate, park the car on flat surface. Pull the hand brake up, start the car, depress the foot brake pedal, depress the clutch pedal, put the car in 1st gear, press the gas pedal and leave the clutch pedal at once, while keeping the brake pedal depressed.
Follow one of the two following statements:
1. Engine does not shut down and remain start. (Clutch plate, pressure plate and clutch bearing defective - Replace all as a set)
2. Engine shuts down. (Clutch system is OK and does not require any repair).

You have to thank the Gauge that shuts down your engine when hot bec. it wont knock...you have to clean your radiator and see if the coolant inside it run through the radiator holes to the engine water jacket to make sure your engine will not over heat...For the fans, find the fan relay...it's under the hood in the fuse box...

You'll have to have the trans pulled and rebuilt

With all that slipping, it is beyond any other fix

Lemme guess, the check engine light is on, too. There can be dozens of causes, like failing sensors, bad fuel pump, etc. Take to a mechanic for diagnosis.

, pull a plug wire and ground it to the engine body and check for spark. if spark then
check your fuel system pressure, fuel pump

Did you ever figure out what it was? I have a 97 accord doing the exact same thing

The only way to For sure fix this is to have a Mechanic run a Diagnostic Check on the Entire car to locate the Problem. Fixing small things here and there will not get you anywhere with this Honda.

this sounds like a fuel pump issue. It could be the pump, or it could be the Master Relay.

it sounds like your coil pack is going bad, replace it.
