Hello,

Ive had some trouble with my 2003 crv. About a month ago, it decided it needed me to press the gas when starting the car. About a week ago, it stopped starting altogether. I did a lot of basic tests that have led me to replace the spark plugs, ignition relay, ignition cable, battery, and negative battery cable. (All of these needed to be replaced regardless of outcome)but its still not starting.

I have checked all of the fuses and they all seem to be fine. Im not getting any power in the outlet that the ignition relay plugs in to. Could this be due to a faulty ignition switch? Or bad grounds?

Currently when i try to start it, i hear a click and sometimes a very slow sputter, like it wants to turn over but it just cant get the energy. All of the electronics and lights are still functioning.

Any help would be greatly appreciated. Will provide any other info needed.

First thing to do is to verify the relay is the ignition relay.
Then verify that power is going to the ignition switch
And that power is coming out of the ignition switch
I there is power then must check the wire for continuity from switch to relay
The relay socket should have two pins with power when the key is turned to the crank

Should clean the engine grounding strap.
If there is a click then sounds like possibly a faulty starter motor.
Check to see if it is getting the proper power and ground at the starter.
If it is then starter is suspect. Good luck.

Yes, it is the ignition relay, i ended up replacing it.

I found power going into the ignition switch but i have not been able to locate power coming out of it. Looking up a diagram to make sure i tested the correct wires.

I will definitely clean the engine grounding strap.
Will also be checking the starter and its power as well. Will update shortly. Thanks for the tips

Download the Gen 2 service manual
Thanks to @Carbuff2 for the link
Can be found in the Gen 2 forum second or third sticky thread down

Usually there is one power wire going into the ignition switch say blue wire, not sure
And two or three coming out.
Ignition switch to starter cut relay (ignition relay) wire is say yellow, not sure

Tested all and have power in all. Looks like we are heading to the starter. Such a pain to get to in the 2nd gen crv... will update.

Did you check continuity to the starter cut relay (ignition relay)?
Does the relay socket have any power (should have two with the key turned to crank.

Yeah, the starter is still a pain to get to in the Gen 3
Waiting for the update.

I got a continuity reading of 16! But my test light was not getting any reading. Checked the voltage and its only getting 4.5 volts while idle and when key is turned to crank... 🤔

The starter relay is not engaged while idle, key in the Run or Acc position, only in crank
You get 16 Ohms of resistance?? 4.5 volts? Sounds like corrosion has made high resistance
in the circuit. Volt drop test while circuit is loaded.
You get 12 volts into the ignition switch and 12 volts out of the switch??

Must have been a mistake. Im seeing 12.2 volts in and out of ignition switch and now im seeing 12.2 volts coming from the relay. Still getting 16 ohms of resistance though

Nope. Still nothing.
Voltage seems like its all good. Though i did have to redo the negative battery cable to get proper grounds. That may have helped establish power to the ignition relay. Looking into other corrosion and the starter next. Will continue this weekend. Thanks for all of your help.

So, power going to the relay. And relay is working.
Have you tried to shift the gear selector in neutral and try starting it?
Do you know how to do a relay bypass test.
Youtube has many videos on this.
Warning is that doing it wrong could short out the ECM and fry it
So, do not do it unless you are sure.
The bypass test would tell you if the issue is in the beginning half of the circuit
Or in the last half of the circuit. Last half is the wiring and the starter

Ill research that and give that a shot. Neutral starting was one of the first things i tried but now that i have power, will give that a second shot.

Have you verified that the connections on the rear side of the engine bay fuse box are not corroded?
How about grounds? (That is easy...jumper engine block to battery negative as a diagnostic)

Update:
I ended up replacing the starter. Gosh, what a pain in the butt. Anyway, i got her all dialed in and sure enough, started right up. No trouble or anything. Test drove it around the block and now i have 2 new issues...

1. It goes over 3k rpm before it finally switches to second gear...
2. When i come to a complete stop, it makes a knock sound.

Any thoughts? Was thinking about taking it in to get the tranny flushed and sensors checked but figured id ask here first.
Waiting for check engine light to pop up with a code.

I am glad you got the starting issue solved.
However, am at a loss when it comes to the tranny
And would do as you said. Drain and fill tranny in hopes it gets better.
Then if not then see someone who can diagnose it.

Could you have disturbed the knock sensor during the starter repair? They are in the same area. :oops:

If so, the ECU could be dialing back timing and reducing power.
