Full Throttle Extreme!
Holy shit, dude. Very awesome writeup!
99 Firebird - ls1 swapped
00 s-10 - 4.3 waiting to explode
96 f150 - 4.9 already asploded
P.S. Just prior to the ignition tune up I had some fun with a bottle of SeaFoam. If you haven't done this yet, do it. Pull the intake tube (the engine will run without the MAF) and pour directly down the throttle body. Here's the vid:
After doing this change the plugs, and clear the codes with a OBDII scanner. The excessively rich conditions plus the burning of carbon deposits & crap can and will foul out plugs. The computer will spit out all kinds of O2 codes & MAF codes.
Check out how spotless this TB & intake are after 60,xxx miles & a seafoam treatment. We all know how well K&N's filter the small stuff. It was black in there before hand

Don't forget to mention you need the hands of a small person
to accomplish these tasks. Especially with the crab cap, things
are way tight. My solution is to have the young lady at our local
Custom Exhaust Shop do it for me. To get at it she sits on the
radiator with legs on front crossmember in between radiator and
engine. Works like a charm.
Note: if you have an older truck, there is a AC hose running over
the distributor. If its not covered with foam tube insulation do so.
GM found that the cold AC line would develop condensation and
drip it right onto your distributor.

Excellent Post!....Was trying to beat night fall and was worried I might have reversed the rotor. Good to know it cannot be installed backwards. Now, if I could just get the no start issue resolved on this 4.3!
4.3 No start Issue
High mileage Vortec. Replaced poppet style injection with new spider kit. Had occasional hesitation/misfire but ran fine. New spark plugs, cap and rotor. Had ignition module tested until hot to touch. Ran test cycle like 10 or 12 times without a faliure. Would cut out more if raining. New fuel pump. new fuel filter. Plenty of pressure at motor (62 psi). New ignition coil. Changed Crankshaft sensor. Cranks quickly, will not start. THought about fuel delivery, used starting fluid, didn't work. Didnt even try. CHecked spark at plugs. Bright white/bluish. I have fuel. I have fire. Will not even try to start. Disconnected battery turned on key let sit for 5 minutes to clear any codes. Cycle key on and fuel pump activates..you can hear it pressure up and kinda wine down like pressure is built. Cranks fast but will not kick off. Are there any more components of ignition that I am not thinking about? I understand that the cam position sensor controls the injectors. Even if it failed, that would maybe stop fuel right? If it failed then I would still get a short start on starting fluid then wouldn't I? Any suggestions?
