ok so i got a 92 cx eg that i just recently swapped a d15b7 in too it. so on the first day the car started fine and ran but wouldn't go past 3500 rpm it would die out. so i got engine light on but it was to late to read it so i waited for the next day. and nothing any more i don't get nothing i hear it turn and crank but no start and also the fuel pump would work intermediately .
so today i was on all data and on some forums and they say that the main relay goes bad on these eg's. so i got a used main relay from the junk yard and now i hear my fuel pump work. before it would work only after the seven or eight time i would turn the key. so i solved the fuel pump problem but now i dont have any spark. what can it be. all my fuses are fine and i checked different ecu's and still the same no spark. i got a check engine light and its number cel# 45 which is fuel system to rich or lean. what the heck my car don't even start up so i don't under stand how it could be rich or to lean. can anybody help me with this problem cause i don't know where else to look. i got a bunch of wiring schematics but can seem to trace the problem!!

 

how do you know your not getting any spark?

 

What ECU do you have? Only an OBDII ECU should throw code 45.

 

i have a p06 ecu obd1 and i pull the spark plug out and look to hear or see spark and nothing it just cranks and cranks

 

Post a video of your blinking CEL, because your OBDI ECU should not throw code 45.

Here's how to check for spark:

well my ecu is obd1 cause when i read the the code it flashes 4 long times and one short time so it says that the long flashes are ten and the the short ones are 1 and i just realized that i counted wrong im mean i have code 41 primary oxygen sensor heater. but that still don't make any sense my car has no spark it just cranks and cranks. but it just doesn't START

 

Check for spark like described at the link I posted.

 

yeah i counted wrong i thought that the short ones meant half and for some odd stupid reason i counted 45 and maybe im still might be wrong. i know that i see 4 long flashes and one quick short flash so is my cell # a 41 or am i wrong still?

 

yeah i get no spark at all i replaced the distributor with another and still nothing. cause i took the distributor out of my other eg that i had running and no spark.

 

With the key in ON(II), do you measure battery voltage at the Blk/Yel wire attached to the coil inside the distributor?

 

no havent done that yet i will have to do that tomorrow. i replaced the main relay cause at first i could not hear my fuel pump. but now i do hear it. so could it be that my wiring harness is bad.

 

if i don't have any voltage coming out of that wire then what could it be sir or what would be the next step

 

Does the fuel pump prime? If not, check whether the ground wire on the thermostat housing is clean and tight.

 

yes it does better then it used to with the old main relay?

 

If the Blk/Yel wire does not have voltage, then it is broken somewhere between the distributor and ignition switch. If it has voltage, then start by checking the Yel/Grn wire running between the ECU and igniter unit for a short or open. If the wire is fine, then swap in a known good ECU.

 

ok i have three po6s and 2 other po and i know that all of them arent bad. i swapped them all. so i know that in aint the ecu's

 

ok so i measured voltage at the distributor the black and yellow wire and i get 12 volts. so im getting power to the dizzy but still no spark so what the heck now. im so confused and i dont have anymore ideas

 

spark plug wires?

 

bad coil or ignition module check secondary circuit on coil(pos + to coil output)for correct ohms vtec is 16.8k to 25.2 ohms. Non vtec is 12.8k to19.2ohms. i noticed i didnt have spark and checked this and got a reading barely under the specks, like 12.0k ohms and no spark. replaced coil and got spark itts worth noting that if the starter wire touches ground at all it will burn the coil out if the key is on.

 

Did This issue ever get resolved? I'm having a similar issue.
