Plugged fuel filter?

nofreeride · Feb 22, 2009

Thank you RadMan and RadioHowie.

From the information in this topic, I was able to fix a plugged injector. Cleaned it out with carb cleaner and compressed air. Saved the money I would have spent on a new injector (assuming I can cancel the order). My problems also started with rust in the tank, the PO having stored it mostly empty for several months.

Oh, and C&C, I didn't realize your avatar was almost exactly what I picked. You were first, I will find some other avatar photo.

Thanks everyone.

Your call, no big deal unless you want to have a more unique one. I think there are a few similar avatars out there. (I may not have been first either)

Just got off the phone with Rich at Cruzinperformance.com.

My injectors are headed back to me Priority Mail.

All 4 injectors are flowing within less than 1% of each other.

Priceless!

If you guys EVER need injector work, Rich is a terrific guy to work with. He's been straight and upfront with me every step of the way.

Should have my injectors in hand Monday. :yahoo:

Looks like Sunday is my AVCC install day!

How much? And why not Factory? Just curious.

Factory didn't have any "swap-out" injectors, were considerably more expensive and were very vague about a return timeline.

Had they still stocked the "swap-out" FJR1300 injectors like you got, I surely would have gone that way, but the person I spoke with said "We mainly deal with racebikes now." Kinda spooked me.

Are you ready for the price???

$32.40 including shipping!!

Here's the specs on my injectors:

I didn't swap-I sent 8 injectors, they flowed and matched up the closest 4, and kept 4 for doing it-so it was free, less the cost of the used injectors of course. But that's a right nice deal you got there, have to keep them in mind for my next go-round.

No joy in Mudville.....

Got my injectors re-installed, hooked everything back up and Feej just won't run fer crap.

Check engine light is on, throwing a #16 code. It looks like I've got all the vacuum lines hooked back up, but maybe disconnected one somewhere during the disassembly.

Too late, too dark, too tired to look anymore.

The bike will fire up, run for a few seconds, then shuts down.

I'm about ready to throw in the towel on this, but maybe I can get a better look at things in the light of day this weekend.

Plenty of gas, strong fuel flow, injectors are fine. Plenty of spark. New plugs.

Fook it for now.

Hang in there Howie - you'll get it.. another day, a better attitude...

Hang in there my friend, you're almost there. You've done an admiral job and licked the tough stuff. Now it's just the PITA details.

I would definitely look at the vacuum lines. Once, during a spark plug change I inadvertently disconnected one wee little vacuum line and my FJR exhibited the same systems. I thought I somehow fuked up a simple plug change. It was driving me mad. Took be a while to find, before I realized I pulled a 'RadioHowie'***.

Hang in there, and check everything again when you are fresh.

Hey, I resemble that remark! Thanks for the good words.

Couldn't leave well enough alone...went back out with the trouble light and checked all the vacuum hoses. All connected, dammit.

One thing really bothered me, though...I pulled the vacuum hose off the FP regulator, stuck the end of the tube to my finger and cranked the motor. What's scarin' me is the motor turns over VERY easily, just spins away, and there was barely any discernible vacuum at the hose. Even held it to my tongue (**** any of you with wiseass replies) and what little vacuum there was was pulsating...almost blowing out, sucking in, blowing out, etc. That don't seem right. Shouldn't crank vacuum be very strong?

Combined with the easy spin of the starter, I'm scare to death I've developed a compression issue. Guess I'm gonna rent a compression tester somewhere and give it a check.

Maybe the coupla hundred miles I DID drive with all that rust in the tank has fragged the rings. Nice, abrasive fuel, with powdered iron in it.

Now don't be getting all frantic and weird on us. Your motor is fine. You fixed the main problem. You're just missing something simple.

I got something to try. The one and only time I had my fuel pump out of the tank I had lots of trouble starting afterwards. I *think* what fixed it is when I disconnected the fuel line at the fuel rail and cycled the fuel pump by turning on the key just to make sure it was flowing. It started fine after that. I am guessing there were bubbles or something in the pump or line. So disconnect that sucker and see how it flows into a cup. If good, after reconnecting the fuel line cycle your fuel pump several times by turning on and off the ignition to 'prime' everything. Then give it a go.

And what exactly is it doing now? How long will it run? And when running, how is it running? Smooth or rough?

Fuel flow is fine...it'll fill a quart mayonaise jar in about 10 seconds

It runs smooth for a few seconds, then dies. Throttle position doesn't seem to matter. WOT start attempt results in a WOT run for a few seconds then dies. Idle start does basically the same thing. A few times in might run for 10-20 seconds, but struggles then dies.

What's buggin' me is the #16 code. According to the FSM, it is either a stuck TPS or problems with the MAP sensor. In Diag mode 01, TPS reads normal, 17 to 97 with no jumps or "dead" spots. The other reason for a #16 code is possible MAP sensor problems.

I just checked Diag #3, MAP sensor, and the reading is 0. Should be 10-200mm. And another thing, before I started this adventure, the starter would NOT engage when in Diag mode, but now it does.

I'm gettin' in way over my head, I believe.

RadioHowie · Mar 3, 2009

Just reading through a multitude of other posts, searching on "MAP sensor", I found THIS interesting read from Rad.

If I'm reading this correctly, at idle, when vacuum is at its highest, the vacuum would cause the FP regulator to "open", allowing fuel to return to the tank via the return line. However, I'm getting NO fuel return through the output of my FP regulator while cranking the engine or when the bike actually DOES run...for a few seconds...

This is either a symptom of what I perceived as very weak vacuum at the FP vacuum hose, or possible a fooked FP regulator. With everything else that went wrong with my fueling system, I wouldn't be surprised.

Maybe step 1 is to buy a Mighty Vac, pull some vacuum on the FP and see if I get any return from the FP outlet.

Besides, I can use the Mighty Vac for brake/clutch bleeds on all my rides.
