• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

TE 450 Injector Test

Trouble shooting starting issue on my 2010 TE 450 heard thru a friend you can test injector with 9volt battery. Anyone out there try this and is there anything I need to be aware of so I did not damage injector?
 
Bike back together but still will not start without use of starting fluid? Thinking might be injector not getting power to connector. Is there a fuse or relay that send power to injector?
 
Does the fuel pump run when you turn on the ignition?
If you can't hear it, check for power to it. If there is power remove pump and check. If there is no power check pump relay and for broken wires.
If you can hear it, check the outlet for pressure. If there is no pressure remove pump from tank and check filter and lines.
 
check the filter in the top of the injector.... you will need to replace it if you take it out. most automotive injector places will have a replacement. wind in a wood screw and pull it out with pliers.
pump pressure should be 42-43 psi FWIW. Also check hoses inside fuel pump one of mine had a split next to the crimped metal band.
Good luck

Pump is coming on. I disconnected hose from injector and tested pump into gas can ad it appears to ave good pressure but it did shut off after a few cranks. Not sure if this is safety deal or if pump is going bad. I pulled injector from carb or and tested it while still connected to electrical system to see if maybe is was relay or other. Gas shot out of injector but not with too much pressure. Mayber due to week battery.

It's a safety deal.

pump stops if motor is not running.
 
I tested injector off bike as suggested by Craigy in previous post and it seams to be working ok. Hoping this. Is sign filter is OK.
 
I just pulled my injector last night to clean it like the video shows. I can't believe how easy that is. Used a 9v battery and some B12 chemtool. That was so dang easy. Been meaning to do that for 7-8 years now.

Any luck yet B1anderson?
 
No, 268fords.

I removed injector from throttle body and tested it while connected to bike and it appears to be working. Fuel spits from injector (not steady stream) which I figure should be right or you would run thru fuel too quick. Getting spark to plug thru new battery and bike still start up with starting fluid but not fresh fuel? Thought maybe related to TPS but there seams to be no adjustment. Guess I need to pay to put in shop.

How was the bike running before it acted up? Was there anything weird going on?
 
I'm thinking fuel pressure is probably too low. Check if it is around 45 psi. injector output should be a very fine spray at 45 psi.
 
268fords,

Did not run bad, stalled a couple times and had to pull choke to start when prior rides, I did not. Did not have chance to ride for few months after that so battery was toast but other than that, nothing major.

Have you checked the air boot between the throttle body and the head? They are crap, and a replacement is just as old as the stock one. They begin to crack all over. Quick fix is to smear some silicone around it. Mine hadn't began to leak, but was cracking.

Hooked up pressure gauge to pump and getting less than 10 psi. Local shop in CA. Says pump is $540.....i see some post talking about a regulator but I can't seam to find out if there is one for 2010?
