- This is a 2000 Honda Accord 2.3 Vtech that cranks, doesn't start and has no communication. It has over 230k miles on it. Check the main power relay before chasing powers & grounds for hours. Also shown are the ECU pinout guide and the diagram for the main power relay.

Great post. I've been chasing an intermittent no start for about a year.
It had finally gotten frequent enough that I had to seriously look into the problem.
The no communication was the key,
Thanks. I wish I would have thought through the video part of this fix and got the actual start on film and closed out the video better. This car is started in a later video on ac pro. Power issues can take a while because you have to know if you're looking at the cause or effect of the issue! Cheers
Thanks for this video it helped me a lot I have a 2003 Acura TL and was doing the same problem. The car would shut off when driving also. It was the main engine relay to
What kind of scan to are you using?
I know this vid is old, BUTT is there any way you can post those ecu/pinout diagram
I had the same proble on my 01 Honda Accord lx it turnd out To be the ignition control module it’s inside the distributor
Very informative on the ECU pinouts. What model of the ODB scanner are you using?
It's a Snap-On Verus. One of the earlier models that can be found at a more reasonable price on ebay or alike. It may not be the most advantageous way to get this info if you aren't a regular user. They are real spendy $$$, even used. If pausing this video isn't quite enough to get a decent read, email me at brendan@brickautollc.com and I will see about getting a screen shot of them for you.
Yo quiero saver por que my carro prende y luego se le vas LA chispa
First did it tuen over freely like the timing was off
Question was checking my fuses under the dash in the fuse box. I disconnected the fuse for the srs an n put it back in cuz the fuse was good now no start i here the fuel pump turn 9n but no start
I get fuel at fuel rail no fuel from injecters can put rag with gas in air filter starts tight up.
You have another relay on the right just tapping it it will start your car it’s IPMF relay. If you need pictures I will send it later.
Hi I have an accord same to that, I have the same problem does not show check also the green key, I change the main relay but everything is still the same I was told that the computer is not. A friend told me that it is a fuse but I do not know which, I do not know where it is located.

If there is no check engnie light KOEO, there is definitely a communication issue and that's where I would start - tracking that down. If the main relay in the dash is good, I would start chasing the powers and grounds for the computer. Check the interior fuse panel and the under hood block fuses and relays (check them all, it is easy enough to do to start). If these are all good, I would go straight to the computer and check the powers and grounds there (see end of this video for PIN-OUT of this). If located, will have to then back track the wire to find the short. That's the direction I'd go if no CEL. Good Luck!
It might be the started too. I change the main relay and started on my Honda Accord 1994
Your friend was right. Is in the engine comp. Top left, by the elect lead, look for IG. Or something Loki that I forgot now the number so check all and u be good. Unless it got hot that means dist. With regulator is fried. Don't even mess with the crank sensor, no only is a little pain to get replace. But it will not be the one . Of course you are using the right key we hope, no spark symptoms when using wrong key.
I looked at this video and I have applied the methods brought a new relay yet I still get no communication with the ecm via check engine light
Did you get it fixed my car doing the same thing too
I have crank no start but have communication I believe
Holy crap what a mess
It took a bit to get there but the end result was good (just a relay)...all things considered. I wish I would have taken a shot of it starting to end it - but it runs great, now about 233k miles
Had it been the main relay defective the car would not have cranked. You would not get any power with a bad main relay.
i thought ithis would help because every single problem is the same I even have a 5 spd but 4 dr no vtec. replaced relay, STILL NOTHING FML I WANT TO DIE
