new member2

[Elbert]

Just thought I would throw out a note for introduction. I joined CottonLand a few months ago. I live over in AL and I'm also a member over at STLCA (TN). Wanted to join the MS crew to help support the club. I don't get a chance to come over to MS that often, but I spent more than a few years in Jackson as a "kid" back in the 70's... for the old timers. Been through Brandon and flowood ...many times back in the day...when it was mainly pine trees and woods.

anyway I have a 86fj60, thats kind of a trail truck such that a 60 can be...I go on rides/trips when I can.
I've been working on my 60 here and there and want to get into more exploring trips and so forth, which I guess some call (over-landing) or whatever. My truck not so special and I've done a few mods here and there...but its mechanically sound.

I'm live over in Cullman, AL. Tan colored 60 with the veterans tag and 4plus bumpers...

Welcome! Hope to meet you one day

Hey Elbert! Glad to have you onboard. Did we send you a shirt and sticker? Now that you are a member you MUST come to the Crawl in October! Plenty of fun to be had in that 60. Oct 11-14 this year.

@Elbert is a great resource on Mud. Glad to have you in our club.

yeah...you sent that over back a few months ago when I "enlisted"....

 

[Elbert]

I've met some of you guys...if if briefly on one or two of the rides STLCA does near Jasper and one trip out to TX a few years ago. FYI...This is my machine...its rough...but I'll go almost anywhere in it or at least try to. 86 FJ60..

Yep you'd have fun in that rig at the Crawl!

I'm working on reducing the beached whale look, appreciate the welcome. I've got a few mini-projects going on with the 60, which I hope to get ironed out by this summer, one of which has been a crazy issue with whats called the cam offset. 5.7 vortec timing is controlled by the ECM even though it has a form of a distributor...anyway in the dist is the cam sensor and thats set a code, which so far I've not been able to solve, will have to dive into the wiring harness soon. Recently solved an issue with my stock type CS144 alternator.

All about having fun with good people....

@offr0adlim0 might have answers for ya on that.

@offr0adlim0 might have answers for ya on that.

thanks...I'm going to crack open the shop manual again to make sure I understand the issues on the code I mentioned, I have a brand NEW GM distributor I threw on the truck a few months ago, on the odd chance it was the problem...we'll that was not the answer.

Few scan tools support the 5.7 vortec "Cam offset mode", lucky one of my local friends has an old one that does. I have two or three scanners none that support the cam-offset mode which is $#@%. You need this to set the distributor cam offset angle (basically where the distributor base line is, so the computer uses that as base timeing in a way) and its the control point. So...that sucker has to be really close to the number in the shop manual (imagine 360 degrees of reference...each degree), as I recall its 0 degress at 1,000 RPM. I hope the issue is in the wiring harness vs. ECM related, because at last read...all things now point to the wiring or ECM.

Have you done a relearn for the cam and crank correlation?

 

[Elbert]

Have you done a relearn for the cam and crank correlation?

I have not. I don't recall seeing a "re-learn" process in the shop manual. What I have done is swap to new gm distributor and attempt to set cam crank offset, the trouble code reset after I cleared it as I recall (this was a few months ago) and I've only starting looking at the truck again. I don't recall seeing a re-learn procedure. Are you aware of the steps?. I have a shop manual, but its been a few months since I was surfing around in it. Code is P0340 Its kind of been on the back burner and I've not done much on it as noted, so trying to get back in the mix and get the problem solved. I do need to spend some time in the shop manual because I just hit the high points before and let it drop for a while...dealing with work and other things got in the way.

 

[Elbert]

so I've looked back through volume 2 of the GM shop manual for 1999 which matches my engine year mode. And I'm going to run through the procedures as noted in the DTC P0340 troubleshooting flowchart..etc, page 6-1163 for those "reading silently" there is a re-learn procedure buried in this chart and its called "CKP system variation learn procedure, which is further defined at page 6-1398 of volume 2, it does note that this is used when replacing the ECM or what is now called in the shop manual the VCM. What is unusual or may not...is that at the operation of replacing the cam sensor page 6-1500 no mention is made of the anything other than the physical actions needed to replace. So my battle plan is to follow the DTC diagnosis noted on page 6-1164 for the trouble code and then refer to page 6-1427 for the camshaft retard offset adjustment.

I'm not sure at this writing if aftermarket scan tools support the CKP system variation learn procedure or if you need a tech 2 scan tool (i'm referring to the hand held type scan tools) rather than some of the pro models like snapon or others that are 2&3K in price or more. I'll report back in when I solve it or run into roadblocks, I do suspect a wiring issue in the harness (one of the two wires) that feed the camshaft sensor at the distributor. There are some defined tests on the wiring in the trouble code flow chart. One of the choices at the bottom of the flow chart is "replace the VCM" and then run the CKP system variation learn procedure. Like a lot of things...on the wiring issues "replace the ECM/VCM are the last resort options"

A number of variables in the mix, so I'll post back up where I make headway on this. I did talk to one of the local GM mechanics I know from the past...he related that when you replace the cam sensor you generally just go back and adjust the offset factor and clear the code. So I have to address the issues behind the came sensor because I have a new cam sensor installed , yet I'm unable to adjust the off-set so I have to understand if my wiring harness or wire has been damage or to the best of my knowledge understand where that leads me. As noted there a couple of test to verfiy the inegrity of the wiring ...thats my first step..hopefully this coming friday.
