FI light on. NO fuel. NO Spark. No START.

I decided to start a new post to track and report my progress, or otherwise, regarding putting together my 2000 VFR. Please see below:



So I acquired this 2000 VFR800 FI from a guy who seemed to know nothing much about it. At first when I got it, I thought the problem was just misrouted vacuum lines as I noticed right away that some lines were not connected. I quickly learned otherwise. The bike cranks and turns over strongly. but fuel pump isnt priming. Neither am I geting spark.

In order not to wate your time, here's what I have done so far.

FUEL PUMP:

- I jumped the black/white and brown wires and the pump comes to life.
- I have swapped out relays with the engine stop and other relays laying around and no dice on the fuel pumpm priming without being jumped.
- I have traced the black/white, black/brown, green, brown wires to the ECM and have continuity on them all.
- Last week, I had taken out the throttle body and also removed the injectors. I used the syringe setup video I found on Youtube to clean the injectors and confirmed they also spit fuel and aren't clogged.


CHARGING

- Have swapped the R/R with a MOSFET R/R. I forgot the seller's name now. Roadstercycle or something like that. R/R is directly connected to battery as suggested by seller.

- My stator wires read 0.1ohms in all combinations of A-B, A-C, B-C. And they have no continuty with ground.





The wire setup is temporary till bike starts then I will re-wire and shield all the wires.


IGNITION (No Spark)

Pulse Generators

I have swapped out the cam PG, and ignition PG. I didn't have a reference to know if my resistance readings were normal so I bought these PGs and hoped for the best. No dice!!! They happen to read IPG = and CPG =

- They both have no conitnuity to ground.
- They both have an extra ohm of resistance when I check at the ECM end of the connector.

Coils

- The primary coils (8 total - 4 on bike, 4 spare) measure 3.2ohm across the primary. That is the across the colored terminals and the black one.
-The secondary all measure about 14.2k ohms.
-I confirmed 12v (essentially battery voltage) to the primary terminals when ignition and Engine run switches are ON.

Bank angle Sensor

I went through these steps to verify that I covered all ground.

Honda VFR Club - View Single Post - FiX knocked over, now won't start - help!?!

Still NO DICE!!!

Other things I have done:

- I have swapped the ECM to see if the one that came with the bike was faulty. No change in error.

- I swapped the harness with one from a 2001 VFR, along with a new neutral switch. Now my neutral light comes on but doesn't solve my problem.

- Have opened the Kill switch and sprayed contact cleaner in there. Didn't take it all apart as my daughter was bugging me and I was wary that I could just misplace the little parts while trying to keep her away.

- Ensured fuses are fine. took them out, cleaned then, put them back and pushed them all the way in.

- Side stand switch is shorted.

- Everything else works. horn, turn signals, brakes lights, (headlight bulbs broken so I can't confirm that one)



The only thing left right now is to get another ignition switch to see if that would make a difference. While I scout for a decently priced set, I am very open to any suggestions anyone may have.

Also, is there ANY other component apart from IPG, CPG, Kill switch, Engine stop relay, Starter relay, Fuel cut relay that is not connected right, or working right, would cause a no start problem?

 

It's refreshing to see someone throw up ohm readings.
Sucks for your issue, you seem to know your stuff though.
What FI error code are you getting?

 

Yes I bought a complete harness from eBay. It came off a 2001 and it was in better shape than mine for sure. I opened the Orange ground bus and it was shiny. Ididn't dismantle it as I was wary to cause more problems. I will dive into that if nothing else gives. I just need to get better soldering iron and flux first.

 

I'm getting the steady FI light. It just stares at me without blinking. LOL

I'm ready for this bike to take a turn for the better.

If anyone has readings similar to mine, please let me know so that I can know what components are actually good. Also, any cues in the right direction would be immensely appreciated.

 

It won't blink to show you the fault code until you go through the process.
I've never done it though there are some youtube vids of people doing it.

 

If by "going through the process" you mean jumping the service/diagnostic connector' I have done that numerous times. However, I will do it again just in case the god of motorcycles wake up from umber and smiles at me.

Thanks for the reply.

 

That sucks. Hope you get that beast running.

 

Did you ever get this VFR started?

I'm having the same problem with mine. No codes stored, Fi light on continously. Bikes turns over but will never start as long as the Fi light is on.

Not yet, Russ.

I have cleaned out the kill switch and waiting for an ignition switch to arrive in the mail since the ignition switch seems to be the last thing in the ignition system that hasn't been replaced.

I will update as I make progress.

Meanwhile, is anyone in the Oklahoma region who is willing to help check my ECMs to ensure they are working?

 

Oh, hey. I didn't realize that you are in OKC. You should post your location on the map. If after you install the ignition switch it still doesn't start then let me know. Maybe one of these weekends I can come down to help. I do residential/commercial troubleshooting for a living. Although auto electrics are a whole different set of voodoo skills. At least your problem is in a 6 foot area instead of somewhere in a 100,000 sq. ft building! Maybe just having another set of eyes on it will help. Do you have the factory manual? I have the sixth gen which is similar but there could be small but very important differences.

 

I so want to go back and edit that post to remove "go through the process."

 

That would be very awesome. I see you aren't too far from Catoosa. I actually work in Tulsa during the week and return home to Norman, where I reside, on weekends. I will give you a buzz if it doesn't work after installing the switch. very grateful for the offer to help

 

Have you bypassed the bank angle sensor or tip over sensor? I would think a bad one would cause the same issue. My PCII went bad and it took me 5 months to figure out that was the problem. It was intermittent and no warnings either.

 

Ok, well the new kill switch will probably fix it. If my key is on but the kill switch is off - It is in the exact same state as your problem. Flip the kill switch back to on and fuel pumps prime, Fi light shuts off. If new switch doesn't work, check the switch wiring.

 

Quick UPDATE!

Please don't buy a 98-99 ignition switch if you have a 2000-2001 VFR800. They do not have the same connector. 98-99 is a 3 pin connector, 00-01 uses a 4pin connector.

BUMMER!!!!

That means I would have to wait another week before I can know if a bad ignition switch is my problem.

Does anyone know how I can modify the 3 pin to work with the 4 pin? Or what the wire colors represent?

 

2000-2001 4 pin



1998-1999 3 pin

Person had the same symptoms and it was a bad kill switch also. Here is the ignition system if you don't have a manual.
