alright heres whats going on...i did a b16 swap...i forgot to drain the gas...so i ran it with shitty gas then put premimum in it...as soon as i did that the car went to ****....for a while my car would try to start and then it would just die...so, i figured it was bad gas cause it had been sitting there for a while...tonight i put a new fuel pump and fuel filter....sure enough it started right up and ran great....as i was leaving my house it started doing the same thing, it would start and then just die...checked for codes and it was throwin a code 3...could it be the map sensor thats causing this....or can i just reset the ecu and it will be fine? let me know something....thanks much

 

forgot to add this.before putting the new fuel pump and filter in i drained the gas completely and after installin the filter and pump i put new gas in. just to throw that out there

 

what car is the b16 in????????

 

a problem with the map will cause it to start and then die suddenly and i am assuming that is what a code 3 is so just buy another map.

Ok have you took all the proper steps????
Dual point fuel injection to multi port can be a real pain in the A$$....
One thing people forget it to do, is switch the wires around on the Tps....
This will cause the motor to run like butt cheeks.....


As far as code three " Check the electrical connector at the sensor for a snug fit.
Check the terminals in the connector and the wires leading to it from the PCM for looseness and breaks. Repair as required. Also check the vacuum hose to the sensor for cracks. The following tests are based on the assumption that the wires are good."

" Code 3 indicates an electrical problem in the Map sensor."

" With the ingnion key ON (engine not running), connect a volt meter positive probe to the yellow/red wire (integra) and the negative probe to the green/white (in the harness side of the connector, not the Map Sensor side). There should be approximately 5 Volts
