2 ways used and 1 is short plug socket and open end wrench thru the wheel well or 2 is unbolt the steereing shaft at the flex and move the shaft - change plug and reinstall shaft.

You can also use a 3/8 socket, an adapter from 3/8 down to 1/4, use a 1/4 extension, and come in through the wheel well. Using the adapters and thinner extention gives enough play to get around the shaft. Just barely, but enough.

This 4.3 liter starts up easily like nothing is wrong , start heading down the road and after about 10 minutes of driving the engine loses power, { the more you push the gas pedal the slower you'll go } untill it then stalls , while still coasting I can put it in neutral , and restart the engine like nothing happened and go down the road , { engine runs fine } Then after a few miles it starts acting up again . And when it is acting up if you floor it it will backfire under the hood { carberator ? }

If General motors wonders why they are losing sales , it is because of vehicles like mine 1998 GMC Jimmy , It has been nothing but a money pit , from wheel bearings at over $150 a side tto the fuel pump at over $600 , to having to replace all four ball joints at 80,000 miles , and I haven't even mentioned the rear braking system , I go through brakes about every 5000 miles , I have replaced rotors calipers and pads up to 3 times a year . And now I can't figure out why it stalls ? It has been at the shop for over a week ! That is why I bought a Toyota ! whatever happened to buying american made automobiles that would last and be easy to fix ? If I could order a new truck and chose the year I would order a vehicle engineered in the mid 80's with no fuel injection ! no ABS , no electrical transfer case , etc ...

Well lets start with the backfiring etc - what code do you get as the SES light must be ON? You have a timing problem for the backfire so has it got a new cap/rotor? Then cam sensor in distributor which effects that (starts OK then probems start) but get the code - also a crank postion sensor tells the PCM where to fire. Then if the fuel presure is bleeding down possible fuel regulator leak under the upper intake. A good GM garage can find these in an hour.
As for the brakes the rear calipers must be replaved with rebuilts each brake job - cheap plastic piston and the slides are in the braket and must be pulled out (rubber boot pulls out) and greased or you will eat rotors. Assumes that the rotors are straight and the lines clean.
The other repairs you did are known Blazer/Jimmy ones and soon the AC compressor will go, the alternator, water pump, and keep that cooling system changed every 3/36 or look out heater core and lower intake gasket.

Well my mechanic called and said that the fuel pump was drawing so many amps that when you activate the brake lights or turn signals that the fuel pump changes tone with the flash of the signals or when the brake is applied thet pump changes tone , also he said you shouldn't be able to hear the pump running over the sound of the engine , I just changed the fuel pump not even 3 years ago !! $600 . whatever happened to the $30 fuel pump change ? I'm not impressed to say the least . and yes i've changed the water pump , alternator 3 times and yes the heater core plugged up on me 2 winters ago , DEXCOOL ! what a great coolant "NOT" ! SO I flushed it out and then I caused it to leak , I then put 4 bottles of BARS stop leak into the syatem to seal that up , I couldn't afford the $400 that the dealership was going to charge to replace the heater core , P.S anyone want to buy a jimmy for cheap ?

Well, only the Delco pumps seem to last at all in these vehicles and Airtex has a replacement connector for the pump top that solves many of the corroded connector problems and voltage/amperage problems and a good ground is alos a must. All of the pumps can be heard when the vehicle is running if standing by the drivers side but not while in the cab windows up. Old mech pumps ran at like 10lbs and new injection requires 60 plus.
I have 4 of these so I know when each part dies first hand. When all is fixed they run well and handle pretty well too but as you know they are not without alot of repair and if you have to use a shop gets very expensive fast.
