got motor in everything to my knowledge hooked up. turns over but no run. not sure what it could be. checked CEL's but found that the ecu's i use are just solid engine light. but P07 was working before i pulled motor, P08 im assuming works....so im stumped and cant go to work today no running D15B

 

also using VX engine wiring harness. any help would be appricaiated.

 

more info would be appreciated

do you have fuel?
do you have spark?

 

see im not to sure about that...i think i got fuel, im not sure how to check spark though.

 

Can you hear your fuel pump prime? You will have to check if you have spark also. need info to help you.

 

yes fuel pump primes, don't really know how to check spark...

 

pull the spark plug wire off and try to see if it jumps to a ground dont hold it though. also what ecu are you running?

 

well have spark have fuel now...it almost wants to start but my battery is dead and no longer wants to crank before it starts clicking with a jump. so i need a new battery but, im wondering will it run with vaccum lines missing? cause it is in a VX chassis. BTW P08 is what im useing.

Also missing a coolant line. dont know where to route it it doesnt have a place for it so if i could get a coolant diagram that would help too. or maybe someone just needs to come over and help me trouble shoot this.

check your firing order, and timing...sounds like that might be the problem...and a p08 is fine i ran that with my d15b...

 

k runs and drives(sort of ) now it spits and sputters while accelerating, could my timing be off? also has a rough idle and when warmed up it idles at 100RPM...so any help would be fantastic!

 

check ur timing sounds like you could be off a tooth

 

werd. will check that and let you know if the problem is solved. thanks.

 

Also like said above make sure ur firing order is correct

 

yes firing order is correct, i think the timing is off cause i re-did it but it still sputs in the lower RPM range and now my valves are bent knocks like a 300k motor i guess ill get it timed tomorrow from a shop.

 

timing was done at the stealership runs better but still needs to be kinked out. what else could make it idle low, and run better in the lower RPM range? should i seek a D15B harness and try a new distributer? honda told me the grounds for the VX harness doesnt really work well with the D15B, could be missing some ground plugs.

also they couldnt hook up a reader, engine light just flashes real quick i thought it was code 1, being o2 sensor which isnt hooked up still so could it be my o2 sensor making it run like ****????

 

anyone have some insight on this??

 

yes not having an o2 sensor could make it run like ****

 

yea....the O2 sensor will make it run sluggish if its not in yet....i'm sure once you get that in, you'll run better

 

damn dude hold up.. i just read all ur posts and im sorta confused... list each individual problem you have, and what exactly is not hooked up... pictures would be AWESOME.....

 

x2

alright for sure i know im just disappointed that this is my first swap that i did my self and it didnt go as plan you know. but yes my o2 sensor isnt hooked up correctly its there but doesnt read.... but i dont think that would make it spit and sputter like it does. i will give some pics and re-tell the problems again. thanks for your insights guys just stay tuned please.

It will make your car run really bad, but not that bad by itself. Hook up the o2 sensor, check your grounds, and keep looking. anything done halfassed or was forgotten about is now biting your *** lol. GL

well my first swap was a d15b also, and it went wonderfully but thats just cuz i rechecked and triple checked all connections, wires, plugs, sensors, ect.... thats what im sayin, just get some time set to take some pics, an give me the full description one by one of whats not right... gaurentee if i dont have the answer for u i can at least point u in the right direction..

 

cant send [pics so i mean i can only give you descriptions. so i will try my best here.

1. distributor is all the way advance.
2. lose of power when in lower rpm range as well as high but it seems better higher.
3. stutters in the lower rpm range.
4. rough idle when warm usually 100-250RPMs
5. when cold seems everything is fine and gets uh scootin'(rarley)

so i dunno what the hell is wrong but i checked my grounds and the tranny one was loose but didnt change anything. swaped out IACV and no change. changed distributor with VX one. no change also. so im stumped could it just be lost of air maybe IM? vacumm im not sure about if you could get me some sort of idea where to look. i checked everywhere but vacumm lines im not sure about on the JDM D15B so i dunno where to look for those. also my VX intake pipe doesnt work with the D15B unless i change the TB to the VX one.

 

alright lets start at the top... why is your timing fully advanced..??
