Man, this is a dream vehicle for me. I want something almost identical for a driver/explorer. Very cool man!
updates?
Not yet
My ignition Tumblr got stuck in the on position so I disconnected the battery got to deal with that first but probably won’t have time till Wednesday my wife’s at work today so I got the kiddo and I work a 24 shift tomorrow I’ve got the plug photos I think they looked pretty normal except number three cylinder the gap on that spark plug for some reason was pinched .020 maybe bumped it when I was putting it in not certain
So far this is where i'm at got a few more things to check on the list
coil check
New Pos and Neg Cables all ground wires check
timing set at 2BTDC check
IAC check
fuel pump relay check
fuel pressure 7.5psi seems low could this be the problem?
Spark plugs AC Delco CR43TS gapped at .040
I Was running two bottles of techron through the system right before I took the plugs out(brown color)?
Gotta drop the tank and get a fuel pump hopefully this weekend
May eventually get the progressive springs from ORD but with the tuff country leaves it does pretty well.
need to fix a few more wiring issues and complete the interior
Yes, you need at min 11psi, 11 to 14psi is a good range.
just bought an ac delco made in brazil pump EP386 and filter
couldn't find any made in usa gonna put it in this next week

Put in New filter, pump, Coil, Plug wires.
Runs smooth idles smooth but still occasionally takes an extra second to fire up. Might just be cause im comparing to My 2012 Tahoe?
Bigger issue according to my plugs
If the deposits are on one side of the plug, this is an indication of upper engine wear valves, seals, cylinder head
