Hi, i got my car shut engine off while running. What i need to do is switch off ignition switch, and start it again. And check light on when engine die while running. But i cannot get any error code, i used clip paper and jump scs connector, no blinking it just static check light.

And when i on ignition switch, fuel pump running continuously..it should running and off after few sec, and the check light off right? in my case, fuel pump running continuously, but the check light off after few sec. if no clue how to start troubleshooting this problem. Please anyone can help?

UHHH!!!! WTF did you just say? LMFAO!

Anyways to check a check engine light. If your CEL is on while the car is running, then yes you have a CEL= Check Engine Light.

Now find the blue 2 pin connector located in the passenger foot area usually behind the glove box by the blower motor. Now insert your key into the ignition and turn the key forwars 2 clicks. Do not try to start the motor. Ok now all your dash lights are on. SO now jump the connector using a paper clip, or wire, or something of the sort. Once jumped your CEL will start to BLINK.

LOng blink =10
short blink = 1

For an example.

bbbbbbllllllliiiiiinnnnkkkk pause.....bbbbbbllllliiiiiinnnnnnnkkkkkk = code 10

now blink blink blink= code 3

now bbbbbbbbllllllliiiiiiinnnnnkkkk blink blink =code 12

You have to pay attention to the time between the flashing lights to determine if you have more than 1 CEL.

I just had an issue in my dizzy lately that kept shutting my engine randomly off... ending up being Cylinder positioning sensor... it went bad from all the rain/humidity here in FL :lol:

I got CEL code for MAP sensor, normally if MAP sensor problem or bad it is imposibble it shutoff engine while running? And why my fuel pump continue running after i switch on ignition switch. Mostly all my friend car the fuel pump run and stop running when ignition switch on no start the engine.

The ECU/ECM controls the PGM-FI Main Relay, [ground to fuel pump relays coil] either the ECU/ECM is bad or the lead from the ECU/ECM to the PGM-FI Main Relay is shorting to ground.

Mine civic ferio 1994. I just replace burn capacitor at c29, c30, c31, c32 and r88 that connected at middle transistor q22. Other component look fine, but i dont know if any component that faulty cause main relay short to ground

Ok after test today, while running car die and there CEL, i try to check blingking code, and i got CEL code 15, ignition output signal. Also i try to plug out main relay, fuel pump still running. Also plug out ECU fuel pump still continue running.. It is my distribute problem?

Finally i found some genius person that modify fuel pump direct on after ignition switch(ii). After i checking main relay wiring go to fuel pump, there was cut, and fuel pump wire up direct to ignition switch. I think old owner my car dont know that main relay problem that cause fuel pump not working, so he/she wire up direct ignition switch go to fuel pump.

And the problem is main relay pin 7 broken, that cause fuel pump not working, so i re solder pin 7 back and touch up all pin. Now car running more better.

here good reading for anyone have same symptom dizzy car :
