i just got my engine wire harness hooked up and changed my plugs and when i start the car it will run for bout 15 seconds and then the engine will flood and shut off anyone know why its dumping too much fuel?

car is a 90 civic si with stock d16a6

 

Because u didnt give us enough details. Why was the engine harness disconnected? What's been done to the car? What about the ECU?

when i bought the car last year it didnt come with the engine wire harness so i bought one off ebay nothing is done to the car except for a header it came with the car ecu is the stock one

 

If you still have the stock parts on the whole motor, there's a few things that could be bad. Are all cylinders getting wet? If so you might have a fuel delivery system problem. You could possibly have a bad fuel pressure regulator, resistor box, ecu, etc. If only wet on one cylinder than you might have a bad fuel injector... Do you have a multimeter?

 

all the cylinders are getting wet i will try a different resistor box i will also look at the ecu to make sure its the stock one how many volts are the injectors suppose to get

 

I doubt its the resistor box. The duration of the injector pulse is controlled by the ECU. The resistor box just modififes the current down to something the injectors can use. If the injectors are running, the resistor box can be assumed to be fine. The only possible consequences for an error in the resistor box is an open, in which case, the injector wont fire at all. Or a short, in which case the injector could die from overheating from too much power being delivered. It doesnt open more or whatever. It opens fully each time, assuming the injector duty cycle is long enough for the pintle to fully retract.

Its either you have the wrong injectors, like 440's in there somehow, a chipped ECU thats delivering too much fuel, or you've got fuel pressure issues, severe ones. Check you FPR and the return hose. U need to measure ur fuel pressure also. It's also a possibility that one of your sensors is bad, like the air temperature or coolant temp sensor. It might think its colder than it really is and pumps in more gas.

well i changed the injector resistor box(the old one was rusty and looked corroded the car was left with no hood and a leaky ceiling in the garage at the previous owners) and it now fires up every time i start the car and i dont smell gas anymore its running a lil ruff but i think i gotta do a tune up and oil change and eventually get a new radiator

 

well i just figured out why its running ruff now it needs a TPS and my friend is giving me one so after that it should be running good
