motor turns over fine but does not attempt to run. i have replaced the icm, coil, rotor. was throwing a code 15 but not anymore. i did the wire checks and everything checks out fine. did voltage and resistance checks on injectors and they check out fine. fuel is on bottom of spark plug when i remove them. i havn't messed with the timing but ill check later. the last time it attempted to start it kinda sneezed. turned over i had to push the throttle and then it kinda jerked and spat smoke out of the intake manifold and died not sure what that means. also started to backfire if it ran.

also my ems reads the engine load at about 102-104 k pa with the motor off not doing anything. it shows that its to high. would that cause major problems if so y did it run before

 

looked today. doesnt have spark. wtf

 

What intake manifold are you using? What distributor are you using? What injectors are you using... What ecu are you using? Modified ECU?

 

i have a a4 manifold on the way but used original im. im is now off. i could take pix of inside if needed used the original dizzy, just rewired it original injectors and an aem ems as well as the p06 with vtec added and h22 map

 

H23AVtec manifold wont work with OBD1 injectors unless you open the nose of the intake manifold runner for the difference in the injector angle.

It is easier to just swap to a normal H22A intake manifold. Swap the Throttle Body from H23AVtec to H22A manifold since the H23AVtec Throttle Body is 65.5mm quite larger then stock H22A.

OBD2 H23AVtec injectors will not work with OBD1 ECU. Need OBD1 H22A 92-95 Injectors. They are peak and hold Low Impedence and will require a resistor box if you don't have one.

Double check your distributor wiring... from the obd2 H23AVtec to OBD1...

P06 with vtec added and H22A base map should be okay to get you going.

 

im using h23vtec injectors which are obd2 when i said original i meant the h23 parts

 

Did the timing belt snap? Does the dizzy get battery voltage? Does the Yel/Grn wire have a short or open? Do the three dizzy sensors have proper resistance? Are their wires fine?

 

OBD1 ECU Needs OBD1 Injectors... Need OBD1 92-95 H22A Injectors... If you don't have a resistor box for injectors that will need to be wired in. 88-91 Civic/Crx carry resistors.

 

i have the resistor box but not installed. ems called for saturated injectors. i checked resistance and voltage on injectors and they checked out to spec. and they also read fine through the aetuner.

 

timing belt didnt snap and i checked the coil and icm. both come out to spec as wel as all the wires running to the and the output signal wire going back to the ecu. the outpus signal wire had somehow gotten cut down by the ecu but i put it back together and checked for voltage at the icm and to the pin out on the ecu harness both were on point

 

did you take a part your distributor to rewire it?
if you did, you might have put the coupler on "backwards", causing your ignition timing to be off, you'd have to remove the distributor coupler and switch it back around.

 

no i didnt rewire the dizzy. i rewired my harness. and it was working fine. and it seems the dizzy will only fit one way. i took it off to redo coil and icm and rotor.

 

NOW FIRES!!!!!!! BUT NO START. TIMING IS CORRECT. GETTING FUEL WTF IS THE PROBLEM

 

ttt

 

What does this mean?

 

Are you sure that your wires are in the right order if it fires but doesnt start?

 

im getting spark from the dizzy but it does not run. doesnt attempt to run

 

yes wires were not changed and it ran fine before

 

anyone think it could be cps since its inside dizzy. not throwing a code tho

 

nah i doubt that.

 

turns out main relay was part of the prob. now it somewhat attempts to start but its not quite there yet. im going to upload a vid of what it sounds like

 

i say just try to diagonse it at your local import shop that is great with hondas.... lets see wat they say might cost u 50$ for a check but saves you great time if they found out your problem

 

that would be the idealistic thing to do but not lucky 4 me there is none around sooooo..... im better of blowing it myself rather than let some rat do it and say o well to it

 

wel from reading all the post... since your running obd 2 injectors on obd 1 just try to run obd 1 injectors see what that does......

 

i have to wait for my h22 im to come in. i actually havnt tried for myself but i do a lot of reading and its said that the 23 injectors r at an angle like those of the euro-r 22 thus injectors wont be a direct fit
