What's up with that? Have a 91 Civic Dx, D15b2.

Car ran fine before install. O2 sensor is in. Reseted my ECU before turning over the key to turn it on. Now it wont start.

Any ideas?

 

lol check the fuses and check the connection of the o2 sensor

 

should have put a 4-3-2-1 believe that's your problem you bought ebay and it wont run cause they forgot the 3 when they went cheap.


JK check ya fuses re-seat the ecu maybe not plugged in enough

 

Lol, will do. And the connection from the male to female is fine. Blew in it and what not. But i'll check my fuses see if their blown. That'll be the fuse box in the engine bay though yes?

 

And it did start, yet when i put any gas into it it bogs and dies immediatly. It also has trouble staying on around 900-1100k rpm. While in idle.

 

check your sensors make sure they are plugged in map sensor and distributor plug did you wash the engine or anything?

 

I washed the engine before the install, yet it ran fine.

After the install, car started then bogs and dies. Now it wont start.

 

Check for water in the spark plug tubes! The water is grounding your spark.

You might check for water in your distributer cap too.

 

sounds like you got some electrical items wet...wait till it dries up and try to start it again...!!!

 

yea i fukd ma dizzy and batt up by washing it like that lol

 

take the distributor cap off and pour rubbing alcohol in it to help dry it out unless you have a air compressor or compressed air then blast that beast and blow the water out of it that's your prob..... I kinda thought there was more to the story then just installing a header lol and if you get it running right keep the hood up and let it run for a good 20 mins to dry it out hood closed will fil engine bay with hot moisture.

 

GAy. I'll try it tonight. Any other suggestions? What about that crazy aluminum disk that fits in the front of the cat just after the 2-1? would that cause a problem?

 

Alright thanks 1990hondacrx, will do

 

check your main ground at the battery and the thermostat ground.

this sounds like nothing related to the header. its either coincidence or you accidentally messed with something.

 

no if you washed the engine chances are you got the inside of the distributor wet and its shooting sparks all over inside your cap. next time cover it with a plastic shopping bag

 

just dont use brake cleaner or anything combustible to clean off the cap.
flammable gas+spark=i think you can figure it out.
totally agree with tyson.

 

Yup everything is dry, nothing got wet. Blasted everything, and car won't turn over. Wtf????????????

 

check grounds check power wire and all fuses again under dash and under hood when you turn key can you hear fuel pump priming?

 

if the grounds are good, then i would also suspect the plugs and wires. the wires can be arcing inside the spark plug tubes. it pretty much sounds like the same symptoms you described.

again, this has nothing to do with the header.

 

Yup still won't start. Its backfire'n a lot
