92 blazer 4.3l "w"
ok i just adjusted my timing but im not sure if i have it correct the label
under the hood says 0 degrees but the little metal tab that has hash marks
just says 12,8,4, Before. so i guessed put the timing a little befor
the 4?....is that correct.
also "doc".....you told me where the fuel pressure regulator is by the
injectors but im afraid to open up the whole "vortec" looking thing that
hold everything in. where do i start there seems to be alot of bolts. etc.
and is there a seal. im not afraid of big jobs i just don't want to screw it
up or get in over my head with out the supplies ready.
Did you unplug the EST wire prior to setting the timing? Also, your timing
tab should have 12, 8, 4, 0, +2, +4, etc. to indicate before and after TDC.
You want your's set to 0* BTDC (aka TDC). If you didn't unplug the EST your
timing will be all off.
If you have a "W" engine, it's CPI and not TBI. The instructions I gave
were for a TBI engine so for god's sake ignore them! He he he he. I would
highly recommend going to Autozone, NAPA, etc. and buying a Haynes or
Chiltons for your truck prior to digging into the fuel system. They run
about $15 and are well worth the $$$ for first timers.
How's the oil look? Milky at all?
yes like my chilton manual said i unpluggled the wire but the gauge is only
marked 12,8,4 (at least as far as i can see i will try to get it cleaner
tommorow) i can send a pic if it helps.
and yes i have the chilton book but it doesn''t say much about the cover of
the bubble looking top thingie to get to the injectors and FPR
I have the 89 TBI version of your motor, and guarantee that the markings are
there. Scrape the gunk, and realize that it will probably be blocked by the
magnetic pickup mont tube that teh factory attached to the timing cover.
funny thing is now its running good as compared to a few days a ago
.....temp has dropped here at least 30 degress. from 50 to about 20 or less.
im wondering about the temp. sensor?
iwas just doing donuts in the parking lot snow on the way home from the
J-O-B and it ran great.
ps maybe i'll just drive my wifes jeep on the warmer days.
