thanks for the reference ..
one, I'd ask how is the poster totally sure he has the engine on # 1 TDC
when the dist rotor points where it should.
the only absolutly sure way to tell it's on t# 1 TDC to fire is to
remove the left valve cover and see that # 3 valves are in 'point of
balance' .that is exhaust just closing and intake just open ..
when # 3 does that, and crank pulley says it's at TDC ..then you know
it's really on # 1 TDC to fire.
othewise you don't actually truly know. The distributor can be put in
out of phase or incorrectly.
the other thought is ..
watching the injectors actually spray...hanging out the engine ..as
shown in Bently is a great test.
And ...only ONE little screw to remove 2 injectors per side to get them
hanging on the fuel hoses..
that is NICE ! ..
almost all other cars, even VW jettas with the same basic type of EFI
don't allow this. LIke not even a minute to get injectors on each side
haning out where you can watch them spray.
oh..here's a GREAT little test too ..this is how I do it actually ...
rather than crank the engine on the starter to watch the injectors spray ..
I like to do it by turning the ( or 'a' ) distributors with my fingers
..key on.
and each ignition pulse should make the fuel pump run, and all four
injectors spray together.
I just grab my known-good spare distributor and plug the harness into
it, leaving the engine's distributor in place.
DO NOT ..
to be safe, ever crank the engine without a distributor installed in it !!
If the shims under the dist drive gear get of place...
they can jam on the brass crankshaft gear even ..you could have a real
mess to deal with.
maybe you guys think I'm a grumpy fart ...and wouldn't blame you if you
did ..
and maybe some people can't tell I am exceptionally experienced on these
fine machines ...
or maybe some can tell that I am be pretty clever at times or hyper
committed to excellent results and great value ...
or maybe ya' all can't tell that..in any case,
Isn't it ironic and weird
that someone is running an intentional fraud scheme on me about their 85
Westy ..claiming in legal court papers that I set their on van on fire
and a dozen other insane fabrications..
isn't that just weird ???
To the tune of over $ 40,000 even. Ya all please pray that rightness
and justice prevail here. Thanks !
