my d15b2 wont crank it turns over with a lil fatigue and backfires flames out the intake.. im in dire need of this car to be runnin so plz someone help me out

 

If it's actually shooting flames out the intake, there HAS to be a CEL. Pull it and post it.

 

im new to the honda world. i honestly dont know how to check for a CEL

Since you are new it would best serve you to read to the FAQs in any forum you are in and search prior to posting. Chances are someone has already asked the same question you are.

Also check for correct ignition and mechanical timing. When was the last tune up you performed. Is the firing order correct?

 

its puttin out 41. (primary oxygen sensor heater)

 

ive un hooked the sensor from my headers and hooked the stock manifold sensor up and it still puts out 41..... hhhheeeellllppppp, i really need this car runnin

 

Check your mechanical timing.

 

Done that plenty of times still no change

 

Give some background on what you've done so far, maintenance, mods, etc. The D15B2 doesn't come stock in that car so did you blow your other engine?

 

What did you do to it before it started doing this? Check to see if your spark plug wires are in order if you touched the wires or you left your car un attended where people could mess you you by switching the wires.

If it just started happening randomly than try to get a hold of a compression gauge and check compression in all cylinders to make sure that your intake valve isn't hanging open

 

i knew it didnt come stock in this vehicle.. i baught the car for cheap and had a thrown rod bearing so i torn down and replaced the rod bearings and rings... its not my first engine rebuild ive just never had this happen before
