i put a brand new battery in it and plugs and wires.
i poured trans fluid in the spark plug holes to loosen the rings. let it set for 14 hours turned it
over put plugs back in then tried to fire it up and the darn thing acts like its not getting spark. Any

What did you do about the rotten fuel in the gas tank? You may have to deal with this.
#1206 of 2018 Mileage on a 4.3 V-6
Jun 27, 2008 (3:16 pm)
Another question for everyone out there. I have an '01 4.3 auto trans. ext cab 2wd. The gas mileage seems to be suffering - I am only getting 14-15 mpg. The truck has about 70k on it. I have read reports that there are people getting an upwards of 24 mpg with the 4.3 in the crew cabs, but I find this a little hard to believe - especially in the 4wd heavier truck. However, I do know that 14-15 in this motor is too low and it should be getting close to 19 hwy and about 16 city if not 17. I had a '95 4.3 and it had the older TBI fuel system. It was 2nd generation Vortec. (I think the '01 uses the 3rd generation Vortec?) Anyway it was a "Z" coded motor mated to the Getrag 5 speed manual and I could get about 18 city almost 19 if I was really nice and 22 sometimes 23 on the hwy. Would an automatic tranny drop my mileage all the way down to 14 mpg?? There has got to be something that I can do pretty simply to cure the problem? I would think that even with an automatic tranny, the newer fuel system should be able to at least achieve the same or better than the older one even with an automatic. At the very least come close to being the same. I have changed air filters, run proper air pressure in the tires, run fuel injector cleaner through the injectors frequently, but it still seems like I am getting less than I should. Any tips?? I expect to get about 16-17 in city and about 20 hwy.
#1207 of 2018 Injector won't pulse when hot
Oct 19, 2005 (12:20 am)
HELP, I'm really stuck! My 1990 S-10 has gotten to where it has to be cranked for about 10 seconds before it fires up, when it's first started. Then it spits and sputters a little for a few seconds, finally smoothing out and running fine...... as long as it's moving. But that's not the main problem. Once it's warmed up and then turned off, it won't re-start. Turns over OK, but won't start. Also, if it's allowed to idle for a short time, even at a traffic light, it will die and not re-start. Once it sits and cools off, it will start again. I've narrowed it down to a fuel problem. It getting fuel to the injector, the injector test OK, but the injector won't pulse when the engine is heat soaked. If the engine is still warm and it does try to re-start, I have to vigorously pump the accelerator to get it going. Also, there are no problem codes showing up.

Why is it that all the parts stores show a pcv valve for the 98+ 2.2? Even haynes manuals say it has one. I don't think the engine has one either, so why do they list it?

Most all the aftermarket manuals are slow to update or donít even bother. You need the factory information to get up to date data.
All the GM PCV valves are metal cased, so I can look at where the hose goes into the valve cover and tell if it has orifice or PCV valve.

You should get better mileage than that. I have a 2000 S10 with over 78,000 miles. I get 22-23 mpg on the highway and 17-19 mpg in the city. Two frequently overlooked maintenance items are replacing the fuel filter (every 20,000 miles) and tire pressure. Check your tire pressure at least once a month. Also, fuel mileage is dependent on driving habits. I don't accelerate rapidly unless absolutely necessary. Good luck.
#1213 of 2018 95 S-10 Heater problems
Oct 20, 2005 (10:05 am)
I have a '95 4.3, 4x4, no AC, sometimes my heater throws a ton of heat, other times it barely warms up. I have replaced the radiator, thermostat, heater core, water pump and other parts. I do not even turn the temp lever and the heat level changes. Does anyone have any ideas that could help me?
