4.3L V6 Hesitant To Start When hot - Fuel Pressure Test

K-Tron,
You stated " I literally own no metric tools."
What do you use for the 6mm bolts (10mm hex heads) that are common on our vans?
I have grown to be comfortable with metric system, but it has taken many years to get over the Asian version of metric bolt head sizes, vs. the European version.

Is it going to be the 8, 10, 12, 14, 16 set of wrenches; or 8 10 13, 15 17 set I grab? :confused:

It was not very many years ago, when major tool manufacturers did not even include a 16mm or an 18mm in a complete set.
Also the 16 and 18mm bolt heads are not a very close match for the SAE wrenches, and in some places ( like taking out the front seat with the storage box under it) no SAE wrench allowed adequate movement, once the slop was taken up.
Ahh, the Whitworth (BSW) system...a nut and bolt sizing system which seems to have mostly gotten lost in history.
The wrench that fit the bolt on a BSW standard 1/4" threaded bolt, was labelled 1/4. How unique! When I first saw wrenches that marked :"0BA" and "1BA" I did a double-take.
We 'Yanks' decided to supply our 1/4 inch threaded bolts with matching nuts which could be in different wrench sizes.
In a previous life, I worked on some old British sports cars...that was fun stuff!

Sorry it took so long to reply. I've been away for a bit.

I mentioned the CAT because of the post of LeeAnne
"Once I got the spark back into spec, that showed me that the fuel was messed up. Got the fuel system back to spec and it showed me that the exhaust had been melted and plugged by the spark and fuel problems. Replaced the y-pipe and everything's been great since. "
I misinterpreted the reference to 'melted...' as referring to damaging the CAT.
Yes, rereading LeeAnn's post, it does not say it was the CAT, just the Y-pipe.
My error, sorry for causing any confusion.

1. My name is Leeann. Just like my username.

2. Melted does refer to the cat on my van. My example was to illustrate that one or two problems in one area can cause a problem in another area that affects running just as much as the original problem, just different. The spark problem hid the fuel problem until it was a major problem, and raw fuel melted the internals of the cats and plugged the exhaust. Once I fixed the spark and fuel problems, I had to replace the y-pipe, which is where the cats are on our vans, to complete the repair.

Thanks for Rod and Leeann for clarifying things,this is why this is a great forum.I am glad OP has made progress,we all are happy when our vans are running OK.But,2 things,I really do not know if the winding's in a "proper " term,as usually used as in electric motors only,but,in much of the world,is used as meaning a winding for electrical current.BUT,#2,I was not sure,earlier,but,reading the OP last posts,does he realize the temp sensor he replaced,only gives information,to the instrument cluster,dash gauge,and has nothing to do with the computer controlled fuel injection system? there is a different sensor,for that.Sorry for worrying too much.
