There was a nice long list of items posted on this -- many, if not most,
which could be tested for and detected by very simple means, were one to
use their powers of observation and deduction -- you know, scientific
method and Ben Franklin and the kite, like they started teaching in
what, third grade? Carbon tracked caps leave a carbon track. Do you
have fire? Check the coil output visually -- a nice blue spark that
jumps a half inch plus gap is nice, a fat yellow one barely jumping a
quarter inch is less so. If the coil wire fires to the cap contact,
that is good, as long as there is spark coming out, too -- you need to
check - in this case, specifically the #1 plug wire output at the plug
end and input at the cap end. if you put your hand on the top of the
cap with the engine running and you get bit, you need to replace your
cap and wires -- Seth (Silicone Wire Systems) sells pretty good wires at
a very fair price. Pull a plug and look at it -- if you don't know what
you are looking at, compare it to pictures in old repair books with
pictures of fouled plugs. And so on.
Crank it over with the coil wire grounded. does it crank steady, or does
it go rrr, rrr, rrr, RRR, rrr, rrr? quick compression check, nearly as
meaningful as a screw in gauge, but not a leak down.
This is a 140 isn't it? Is the (stock) right secondary fully closed at
idle? If not, that is a big vacuum leak, especially for #1.
Loved it when life was so simple -- wife's 2001 Alero is getting
obstinately tricky to start, so had to go get a newfangled fuel pressure
gauge for injectors (I've been trying not to get one, but knew it was
going to be in the cards. Hate moving into this modern automotive era.)
-- fuel pressure comes up after several tries but not always at the same
time the car starts -- bad connection between key and computer output is
likely, I think. FPR and fuses are good. No, it is not the Passlock
II, & it runs great, once it is started.
