#4 of 301 4.3 intake manifold

When replacing the intake manifold gasket, what setting should the torque wrench be set on to tighten the bolts that pull the intake down on the gasket?

TBI models 36 ftlbs
CPI models initial torque 35 ftlbs
CPI models final torque can be up to 41 ftlbs
tbi you tighten one side then the other
cpi is tightened in a zigzag patern from the midle
if you are really concerned get a shop manual, they tell you the order to tighten each

For 98up Blazers the final lower intake torque is 11 ft lbs reached in 3 steps - any higher will cause other problems. Most shop books give in inch pounds and most of us have ft lb wrenches. Just wanted to document the correct torque for newer Blazers.
#7 of 301 96 Jimmy Won't start
May 17, 2006 (4:04 pm)
Turning the ignition key produces nothing. There is power to all of the dash gauges, but the starter will not engage. This only happens every fourth or fifth time you try to start it. After allowing the car to sit for a while you turn the key and it immediately starts. This is driving me nuts. Any clue what the heck is causing this??

I have an identical problem. My 92 S10 Blazer 4.3L V-6 will start initially, but after I shut it off it turns over beautifully but just will not start. The fuel pump runs fine. I see gas in the throttle body. Could it be flooding the TBI that easily and preventing further starts?
#10 of 301 1993 Jimmy does not start- Help
Mar 25, 2006 (7:20 pm)
I have a 1993 Jimmy. It has been having starting issues. We have heard everything from the fuel injectors needs to be cleaned to replacing the water pump. We have replaced the computer twice, the second time the garage replaced it free. But now it does not start but turns over. We have it in a garage now and first they thought it was the distributor, but have tested the sensors and such and can not find anything wrong with the distributor or computer. When we had the computer put in, I guess the first garage did some sloppy wiring and now another garage said some of the wiring from the distributor to the computer was burned and not covered properly and etc. They have tested the computer to the distributor and have found even though poor wiring it tests out fine. So now they think it is from the computer up through the firewall into the dash board. I understand it could be very costly to follow all the wires out the computer into the dash since their are so many wires? I have asked if it would be better to replace the harness and they seemed to be reluctant since they said that would be more work? We had it in three different garages and no body seems to know what they are doing, can someone give me some idea what we should do? Thanks
