Glad the ground fixed it, but other things to look at are heat soak on an old starter, as well as timing being too advanced.
That's a good point. I think timing might be a bit too advanced, as I am hearing a little bit of dieseling sound on startup... Is that typical on a FSJ?
I'm not sure what a dieseling sound on startup would refer to, sound wise. Dieseling is when you shut the ignition off and the engine continues to fire for a moment or two, and putters out. I'm not sure how that would relate to a start up sound, as you're starting it, not shutting it off. Dieseling tends to be related to your idle being too high when you kill the ignition.
Its hard to know exactly where to set your timing, most folks will tell you advance up to where it begins to ping under load, then back it off a few degrees. I live at 5000' and I have my hooptie timed to about 13* BTDC base timing. But, these days im running timing control so it does its own thing.
Yeah, bad description on my part... You know the sound when you shut an engine off and it diesels for a second? It sounds like it fires a bit with a knock? The first fire sounds like that occasionally. It's really faint. In fact, once the hood is closed, I can't hear it at all. (which probably means there isn't an issue at all and I'm making my life unnecessarily difficult)
Wow, great pictures! I grew up in NE, and think the Wagoneer fits perfect.
It's never really done is it?
Wow, I've had the same issue with my Wix and Napa Gold filters. I never thought that the startup noise could be related. I think I'll try and STP or AC Delco on my next oil change and see if it helps! Thanks for the tip!Also, just out of curiosity, which oil filter are you running? I used to run both WIX and Napa Gold filter on the 360, but quickly found out the anti drain back properties on both filters were not good. Most of the oil would drain back to the pan, leaving virtually no oil in the filter for startup. Would cause a couple second knock upon startup as pressure built. Not a fun sound. Switched to an STP filter and no more issues with drain back. I think the AC Delco filters are fine as well. I was bummed as both the WIX and Napa Gold filter are otherwise great filters. But can't have 0 oil in the filter. May not relate to your issue, but probably helpful nonetheless.
