ok i just finish doing my mpfi swap. when im driving my car just shuts off and when i try to turn it on it would just die out. do you think my car is getting no fuel pressure? please can anyone help me out

 

Code 4 - Crank Angle Sensor

Top sensor in the dist. and is used for fuel control and misfire detection.

If the dist. base bearing starts failing, it will start heating the sensor(s) up, destroying the magnetism causing a code(s). It will lose 10% of it's strenght, each time it is heated up, to a 170 degrees plus.

In most cases, replacing the distributor is the only alternative. Especially if the bearing has failed.
Honda does don't stock the bearing itself, but other after-market compaines are said to have one.

If you have problems starting the engine, or drivability after the install check your cam aligment. The seizing bearing might have caused it to jump a tooth/notch or two. From the extra drag due to the bearing failing.

Code 16 - Fuel Injector

Code 16 is probably the Main Relay, however it could still mean a bad Injector, Resistor Box tho.
Most failures occur, when the weather starts heating-up for the summer...


If the car refuses to start, but "turns over" on a hot day, try opening the doors/windows, and let the interior cool down. "Then try starting again". May not work all the time, but worth a try anyway. Also, would help in troubleshooting the prob, if it does start. Another place to look is the ECT sensor, refer to the above

 

would code 4 cause me to bog really bad. also when code 16 is on my car is really hard to start after like 10 minutes of driving.
