#1 of 370 93 Blazer fuel trouble by e_net_rider Jun 19, 2002 (7:15 am)
has 4.3 and it died. Found no fuel going to engine. Replace pump and now has pressure at the fuel rail but won't run. Squirting fuel into intake will allow it to run. Any experience in this area appreciated. Thank You. Replies to this message: dcart1 (Jul 21, 2005 8:17 am) rich19 (Sep 18, 2005 3:22 pm)

#3 of 370 Blazer & S-10 by rjbruce Aug 04, 2002 (6:51 pm)
It sounds to me the problem with your Blazer may be the Fuel Injector. I believe the 93 model is still a TBI so it should have one fuel injector. I would pull a spark plug and make sure there is gas on it. If there isn't gas I would guess the injector is bad. If there is gas it could still be the injector if it isn't using enough fuel. It could also be you're not getting spark. If you pull a plug, put the wire on, and ground it to the frame (don't touch the plug, it's best to use pliers (with insulated handles on the wire) you should see spark.   For the S-10, all I can say is to confirm the element is freezing, you can run till it doesn't blow cold, run the heater for a few minutes (man it's hot in here), then flip the air back on and see if it blows cold again. If it does, I'd contact the dealer about it, they may not be able to do anything, but I'd try since it should still be under warranty (assuming you haven't ran over the miles on the warranty).
#4 of 370 1996 S-10 (stalling problem) by ronimal311 Aug 16, 2002 (11:54 am)
My truck was great for the first three years then its been a constant battle. I was wondering if anyone's truck stalls when its hot. It happens mostly after I have stopped at a light, then try to acclerate, and then the motor stalls. It only happens when its hot outside and the engine tempurature is above normal. Any suggestions would be great   Thanks Replies to this message: drglinski (Jul 21, 2005 5:52 pm)
#5 of 370 Running Rough by wmoses3818 Aug 23, 2002 (8:56 pm)
I have a 98 S-10 extra cab with the four-cylinder motor, manual transmission and approximately 90k miles. My truck has been completely reliable up until a few weeks ago. The motor would noticeably miss and then seemingly smooth out and run fine. It got progressively worse; primarily when I would began accelerating after stopping at a stoplight. It misses, but accelerates slowly, and once up to speed it runs fine. I had the dealer check it out and they replaced the plug wires and spark plugs. The problem continued however the dealer said it was fine. I brought it to an independent shop and they replaced the fuel filter and inspected and cleaned the injectors. Still the problem persists. Both shops claim that there is not a problem and everything is fine. Any advice would be appreciated; I am at my wits end. Thanks.

#6 of 370 '94 S10 Overheating Problems by canyon_run Sep 05, 2002 (12:20 pm)
I have a '94 S-10, 4 cylinder, manual, 95,500 miles that has an overheating problem. I have changed out the thermostat twice, the fan clutch plate and the valve gasket seals, and have no air conditioning. It only occurs when the outside temps are humid and above 85 or so. It occurs on the freeway and town streets and only cools down after running the heater on high, but continues if I turn off the heater. Has anyone else had this problem that can make some suggestions, as the garages/ dealerships cannot seem to figure out what's wrong with it.
#7 of 370 Constant Overheating by softwarevp Sep 06, 2002 (10:30 am)
I have a 96 S-10, 4 cyl, manual, 62,000 miles that had an overheating problem as well. It finally overheated quite a bit, so I took it to the shop only to find out that either the head gasket needs replaced or I have a cracked head. Might want your mechanic to check and see if any steam is coming out of your tailpipe. Do you have to constantly top off your coolant levels??
#8 of 370 Hard Starting by mattison1 Sep 09, 2002 (6:20 pm)
My 98 S-10 blazer is start hard in the mornings and after sitting for more than 30 min. When it is running it runs fine. I have replaced the plugs, had the throttle body ckecked, and had the electrical system ckecked. So far I have found nothing. Any ideas welcome.

#9 of 370 Overheatin by canyon_run Sep 11, 2002 (3:41 pm)
The coolant levels are good - that's one thing I've learned to check constantly with this problem. I haven't noticed any steam but I will mention it when I take it in (again) next week. If it's a cracked head, you'll be seeing it on the side of the road. Thanks for the suggestion.
#10 of 370 2.2 engine vs 4.3 by go10go4 Sep 14, 2002 (1:02 pm)
I am shopping for another S-10 used. My last had a 2.8 engine V-6 - EXTREMELY reliable. Almost 200,000 with NO engine repairs. That's no longer available. I'm having a hard time finding a 4.3; almost all seem to have the 2.2 4 cyl. Any experiences with these engines? I have heard the 2.2 is underpowered. Is it durable?
