ok so today after and sudden stop my icar felt like it was miss firing. So checked wires good, but when i pulled out wire 2 and 4 nothing happen so i found it. I switched out the injector on cylinder 2 and same thing. I check the voltage and its not getting ground. I direct ground it(just to see if it works lol).. NOTHING!! Engine has good ground all over and injectors ground is good. I even switched out the resister box and nothing. Any ideas??
maybe timing issue? idk please help

Engine
D15b vtech(jdm)
Wire tuck, everything has been great until now
obd1

Edit
i get power to both but no grounds
engine sparks and runs, but runs like ****

 

Ground is the signal straight from ECU.
Power is from the resistor box - apparently yours is just fine.

My guess is your distributor or distributor wiring.

 

Thanks! ima remove it and go have it tested. I can hear that injectors 1 and 3 are clicking and working because it does bog out and die when spark plug wire removed. In the other hand injectors 2 and 4 do nothing.

So the distributor controls the injectors as well? is the cps in it?

 

Car was running perfect until this sudden stop this morning..

 

okay so injector 4 is working now. Its just injector 2 thats not working. GEtting power but no ground and ive already switched out the injector as well.

 

You will only get ground when the ECU sends a signal for it.
If you had constant ground and power, then the injector would flow gas constantly... flood.
You use a NOID light to check if the injector is being electrically pulsed properly.

The CYP, TDC, CKP sensors in the Honda distributor all send info to the ECU to orchestrate when the injectors fire.
None of them are readily serviceable so you end up having to replace the distributor.

It could be that the timing belt hopped several teeth. This can cause issues like what you describe.

 

YEah i was dumping gas when i grounded it out lol
Okay so i fixed it back to normal and only injector 2 has it, so back to square one. I dont own a NOID light so thats crossed out.
THat sucks those are such coman sensors to replace on other engines too.
Timing will be checked right now.... i have my fingers crossed.

 

timing is good

 

got another distributor and still the same problem! idk anymore, anyone with ideas??

 

Update:
FOr those who encounter this same problem in the future this is what was wrong with my crx. One of the plugs in the dizzy was exposed and baerly even connected. I had to open up the plug and reconnect it because it was right at the beginning on the plug and it was a B*#%H!! Easy fix once found but had me pulling out my har finding it.
