SOLVED


ok i bought a del sol a while back that needed a timeing belt done REALLY bad... so it has been sitting and i drove it home softly after i got it ($700) well i got the timeing belt on and went to run it and it bogs out at 4k rpms

i been looking into it and the head was swapped to a d15z1 head (has po7-1)(sould be vtec right) on a d15b7 block but it does have the p07 ecu for the vtec z1( if right)

only probem with that is if it was a d15z1 it would 92-95 civic vx... well the little circle things say 9|1 1|0 |8 |7 so dont that mean it would be off a 91? or was its just stamped made then,then put on the 92?

no codes or anything runs fine tell i hit 4-4.5k

so stumped... friend said limp mode but i dont think so... please help im so dumbfounded




(((((( FOR ANYONE READING THIS NOW IT WAS THE SPEED SENSER )))))))

 

is your timing on ign/mech did it do this BEFORE you did the t-belt

 

yes but i only tested it once... when bought it the timeing belt was split in half so i didnt drive it more then on the way home ... thought the belt would fix it cus it being the broke made it a little lose

 

well check mechanical timing and ignition just to cross that out.

 

Did you set the mechanical timing correctly for the D15Z1? The D15Z1 mechanical timing is set differently from the D15B7/8 and D16Z6, meaning the camshaft has to be set to a different indicator than the other engines.

 

did ....wondering if the vtec sylanoied is out

 

^or hooked up correctly, meaning did they wire the vtec solenoid up correctly? Does the CEL work?

 

VTEC not hooked up wouldn't make it "bog" that's pretty low also if it were set at 4K.

 

i tested the codes when i first got it and got none... just tried again and i cant get it to even blink... but the cel is coming on when i got to just on before starting not sure wtf

put the paperclip in the dignostics thing and the cel wont come on. idk wtf ima google that now

 

I would think if the VTEC system wasn't functioning it would throw a CEL.

But the VTEC-E engines are a totally different animal, the function and crossover is weird due to leanburn/economy mode, don't know a whole bunch about the workings of that system.

 

Check the FAQ section, good write ups on how to pull codes

 

would still throw 21 22 even tho it's the vtec-e. http://check-engine-light-codes.blog...retrieval.html

on that plug there are 4 holes in total you may just have put it in the wrong holes.

 

should just need the paper clip in the plug right then get the code off the cel blinks... but its not blinking

 

key has to be in the 2(II) position on the ign. as for the plug as I said before there are 4 holes you may be putting it in the wrong 2

^ that exactly what i did and it wont give me a blink at all

 

Are you inserting the paper clip into the female metal pins or above them in the empty holes?

 

well im going to say it a 3rd time...4 holes in that connector 2 are the right ones and the other two will not do anything. check that the connector isn't lose or the wire is open. try a different ecu if you can

 

^sorry i read that and i tried every possible way it just stays on...

into the pins where it holds the clip in..and even tryed every hole just to make sure

 

ok I made that mistake when I first got my car so I always tell ppl that when they say the cell won't blink.

you say it shows on start up for 2 or so seconds(as is normal) ?

i'd say try a different ECU just to eliminate that

 

no it just stays on... with clip in and out .... thing the wires that i jump could be messed up somewhere?

 

CEL stays on solid, whether you have the connector jumpered or not? If so, that's Code 0

0 ECU - ECU circuit problem

-code 0 is defined by the CEL remaining on steady both without and with the service connector jumped.

-If the engine does not start, code 0 indicates that the ECU is not receiving power and/or ground or that the ECU is bad. When code 0 is thrown, start by (1) checking fuses 24 and 31 (92-95 Civics) or fuses 13 and 44 (96-00 Civics), (2) resoldering the main relay, and (3) cleaning and tightening the G101 ground attached to the thermostat housing.

-If the engine does start, check for a short in the service connector wire or the CEL ground wire that runs to the ECU.

 

ok so Engine Control Modual (ECM)?

 

Code 0, could be any of the things listed above, does it start with code 0?

 

yes it starts fine just the bogging problem... also fells low on power to... why my friend things limp mode ..
