  • 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 The previous version was outdated and no longer supported.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!

New Temp Sensor Installed: Now What?

Get a clear plastic juice bottle, get one big enough that the fuel pump assembly will fit down in it, you can use an oil jug, it's just harder to see the gas flowing. Cut the top off, and put a few inches of gasoline in the bottom, put the fuel pump assembly down into the can. Make up some pigtail wires that plug into the fuel pump and then use your battery to apply power to the pump. You should get a powerful stream out the final tap under the surface of the gas. Watch for leaks in all the connections before the final tap. If there is a leak in the hose before the pressure regulator, you won't be getting enough pressure to the injector.
 
Well, the fuel pump seems to be working just fine. Took it out and submerged it in a container of fresh fuel and cycled the key. Pumped a study stream of fuel with no hesitation. I put it all back together and tried starting it to no avail (with fresh fuel). I took the plug out just to check it and noticed it was relatively dry for the long starting attempt. Maybe my injector is bad? Any way to test them? Any other thoughts?
 
Check the wiring to the injector. The Green with red stripe wire is the one that supplies power to the injector. Check for worn/bare spots on the wire that might be grounding it out.
 
Well, I was going to say check your stator pickup, but your plugs dry... Check the wire like OHR said.
 
I checked the wires to the injector, they are fine. I checked the injector with an ohm meter and had a reading of 10 (not sure what is specked for acceptable). I checked to ground and that checks out fine. I used a test lamp on the injector and observed it stays on the whole time the fuel pump is cycling when you first key it on. Unplugged the ECU a few times and blew the dirt out. Put it all back together and noticed the plug was getting wet now, but it will still not start. Did notice it is getting enough fuel while I am trying to start it that it is leaking out of the exaughst expansion joint, too much fuel now? Maybe a bad ECU? The plug has a great spark too. It is beyond me now, I thought all you needed on a combustion engine was gas and spark. TPS sensor? I don't know. Out of town on business the next three days, I will try again this coming weekend. Not sure about the flywheel key, would that throw off the timing? Anyway to check? And would that cause symptoms before just flat not running anymore?
 
Well I might have to dig into that this weekend then, because it is getting air also, unless there is a sensor controlled by the EFI system to check.
 
Anyone have any issues with their crankshaft position sensor? I took the covers off both sides today and everything looks okay. It is a little more work than I thought looking into the sheered off flywheel key possibility. I guess I am making a two hour trip to the shop next weekend.
 
Dealer has told him the TPS is bad, and wants $500, in another thread.

Try disconnecting the battery and leave it undone for 20 minutes then hook it back up.
 
I had the battery out several times to charge during the course of troubleshooting. It was out for well over 20 minutes. Still would not start.
