S-10 :: 2002 Blazer Has Power But Won't Crank / Start
Went to start the truck, turned the key - dash lit up, fuel pump primed, turned the key all the way and nothing. Truck did not even try to turn over, headlights did not dim, no starter, no crank.
I checked/tested the following:
-Battery and terminal connections - good fully charged 12.3v
-Ran battery charger on slow charge 10-15 min (quick) to full 13v
-Wiring to starter - good
-Relay box under hood - has power
-Starter relay - has wiring diagram on it - tested good.
-Every ignition related fuse in the relay box - all good
-Every ignition fuse in the driver's side dash fuse box - good
-I wiggled the ignition switch while turning every possible way - no crank
-I ran the gearshift lever through all the gears, tried to start it in neutral - no crank
-Rolled the truck a little, put in park - no crank
For some reason I decided to double check the # 24 RDO IGN fuse - it was fine. With the fuse still out I tried to start the truck and it STARTED!
I turned the truck off, replaced the fuse and the truck started again and, so far, ever since. I do not think the # 24 fuse had anything to do with it; I just got lucky.
Chevrolet - Blazer :: 2002 - Oil Mixed With Coolant
A co-worker has an issue with a 2002 Chevy Blazer where the oil is mixed with the coolant. My understanding is the usual causes of this are blown head gasket, cracked cylinder head, or cracked engine block. If the cause is a head gasket, they'll probably fix it. Cracked cylinder head makes fixing it iffy. A cracked engine block probably means junking the vehicle. Is there a fairly inexpensive way of determining the cause?

I own a 2002 Chev. small blazer with 4 wheel drive available. Largest V-6 available. There is a clunk sound I can hear and feel as this vehicle is shifting OUT of 4 wheel into 2 wheel drive. Going from 2 to 4 wheel drive is perfect. First mechanic (test drove alone) said he would have to tear apart the front transfer case to determine fault. 2nd mechanic (with me along) did power brake slow turns in parking lot. Said the electric shifter was bad and would have to tear apart the transfer case also. Neither mechanic put the vehicle up on a hoist.

I have an 02' Blazer 2Door 2WD 4.3L vortec. Great truck - very low miles. About a month ago the fuel pump went out. She was showing signs / not starting on the 1st/2nd try and finally wouldn't start. It's a 12 year old pump and I was also that guy trying to make til Friday on a quarter tank - so no complaints so far. I checked the relay and fuse, all good there - so I bought a new AC Delco and fuel filter. Drained and dropped the tank, cleaned and dried the tank and installed the new fuel filter. The pump came with a new pigtail - so I wired in the new pigtail, attached the hoses and re-attached the tank. Not bad for 6 hours of work ( first time - don't judge ). She fired right up and ran like a champ / about a week later I stopped and filled up the gas tank. Next day - no start / no whine from pump / 0 psi at the schrader valve.
Assuming it must be an electrical issue - I dropped the tank and tested the gray power wire / 12 volts. But to be thorough / in case I made a mistake / I stripped and re crimped all the connections, heat-sealed the sleeves and wrapped in all in electric tape. Tested the pump - she hummed like a kitty. Re-installed the tank and she fired up like a champ. Drove around a couple of days - stopped and filled the tank with gas. Same thing - wouldn't start right there at the pump. i poured fuel in the intake - she would start and run until the fuel burned up.
No hum from the pump. had it towed home ... again ... began to siphon my now full tank of fuel to drop it yet again. At about 1/2 way , I tried her and the pump primed and she started right away. For the past two weeks I have been unable to make it NOT WORK - but i am worried to go very far , less i be stranded again. on the gauge I get 60 with the key on and 56 running. With the engine off the pressure holds for quite a long time - well over an hour+. So what would cause a brand new AC Delco pump to not work only when the tank is full - then start working when some of the fuel is removed?
Chevrolet - S-10 :: 2002 Crank / No Start When Wet Outside
I have a 2002 chevy s-10 pickup, 4.3 V6 vortec, 4 wheel drive. It has developed a crank-no start when it's wet outside. Snow, rain, even high humidity.
Things already done: cap/rotor/wires/plugs; coil; fuel pump (fuel psi between 45-55). There was an issue with the distributor being chewed up by the cam - cam gear was inspected and is supposed to be in good shape. A used distributor was installed by the local shop. Engine has 200,000 miles. I was told the timing chain is a bit stretched but there is no timing problem.
Good power, smooth idle, no smoke and there is no engine codes generated by the crank-no start problem. I have power to the coil when it's happening, fuel in the system, even have a spark out of each cylinder wire but it still won't start. I think the car is possessed!
Chevrolet - Tracker :: 2002 - Crank For 20 Minutes But Won't Start?
The problem started several months ago. At first it would only happen once in a while and would only last about 5 mins. The first time it happened I had it towed to my shop and it ran fine when it got there. Go figure. They told me they couldn't diagnose it if it wasn't acting up while they had it. Makes sense. But it never does it when I'm there for routine maintenance. Now it's doing it for twenty minutes at a crack. It's usually fine around town unless I get stuck in stop and go traffic. When it usually acts up is when I get on the road between work and home.
Every time I stop for gas I have to wait for it to decide it wants to start again. All of this is putting heavy wear on my starter. I changed the oxygen sensor (position no. 01), because that was the only error code that showed up. That didn't fix it. My mechanic says he thinks the next best step might be the cam and/or crank sensor. If not that, then he thinks we should change out the brain. Somebody else said it might be the fuel pump goin out. because I travel too far for work and I can't afford to fix things that probably won't solve the problem.
2001 Blazer Crank But Not Start On The First Turn Of Key
For about two weeks, my Blazer would crank but not start on the first turn of the key. After a couple of tries it would start and as long as the engine was not off for more than a few hours, it would start again with no problem. While driving however, the engine would periodically "hitch" like it was missing a spark, or not getting any gas. As of last weekend, the engine will not catch at all, and a light on the dash shows "low fuel" even though the tank is almost full.
Spoke to a mechanic who (without looking at it) diagnosed a fuel pump problem at a cost of around $1,000. Is there any other problem which may cause this issue? I have very limited mechanical ability, and cannot pull the spark plugs to test them, as they seem to be buried in the lower half of the engine block.
S-10 :: 1997 Blazer Leading Up To Crank But No Start Condition
Wants to crank. I notice when I turn the key switch on (not start) the gas gauge pegs out as if a super full tank and no fuel pump noise. At times, leading up to the crank but no start condition, I would turn the key on, hear the fuel pump and the gas gauge would indicate proper fuel level. When this happened, the vehicle ALWAYS started.
Here what I know now;
1. Fuel pump works. As indicated by the red auxellery jumper lead inside the engine well.
2. Good fuel pressure.
3. Starter checks good.
4. Battery hot and leads are cleaned.
5. Grounds in engine compartment and at fuel tank are cleaned.
6. Vehicle does have gas.
7. Air bag light stays on, even after pulling battery leads, letting set, and reinstalling.
This ABS light would come on and go off independently before the "crank but no start condition". So I'm assuming that the ABS might be its own problem; but not contributing to the crank but no start condition? There were problems leading up to the no start condition. Vehicle began to become hard to start (but would start). After starting (at idle) if the gas pedal was pressed aggressively, the "service engine" light would flash on and off rapidly and the "ABS" light would come on. At this point the vehicle wanted to die. No apparent codes were given.
Now the "crank but no start condition". Before this problem, the vehicle was sending the code for 3 o2 sensors. But a new fuel filter corrected this problem completely with no further apparent problems. Then (about 4 weeks later) the "crank but no start". I do not think the fuel filter and the "crank but no start" problems are related.? No other maintenance has been done to this vehicle that might cause this problem. At this point the manual I am using is useless...
Chevrolet - Blazer :: 1994 - Can't Go Over 45 Mph?
Been doing a lot of repair's on our 1994 Chevy blazer. It's a 4.3 v6. We finally got her running and now it seems like it can't take high speeds for very long without over heating and eventually smoking some. Had to bypass heater core, it's clogged. That worked with temp. Also replaced radiator and cap. Replaced both heads, took thermostat out. That worked with temp too. It has a new water pump, new exhaust manifolds, has good spark plugs, oil changed and oil filter. Kind of at a loss.

Our 2000 blazer LT 4.3L 4 door 4wd has 190,000 km (about 115,000 miles). 3 Button dash control. Transmission was rebuilt at 100,000 miles (main troque converter spline was shot). The 4 wd will not engage in either hi or lo.
Whether moving or not, press 4 wd lo, light stays on. but nothing happens. I cannot hear the transfer case engaging.
Had a previous problem, (withflashing light): found the vacuum hose under battery case was worn through.
I do have a service engine light on the dash. This may be unrelated, because 4wd stopped working long before service engine light came on. I have changed the Oxygen sensor, but no reset the fault yet. Where to start.

I got my blazer look at and here what they come up with so far. Transmission fluid is discolored. Transmission shifts late between 3rd and 4th at 52 mph. Transmission slips between 2nd and 3rd gears at 32 mph. Lock up 41-43 mph in and out. I never told them this but I change the transmission fluid about a week before i took it there and when I check the fluid it was nice and clean and not burned like he said it was. He said most likely it internal damage.for them to take a look in side to see what is wrong with cost me 400.00 and I said no.

my 97 chevy blazer has a lot of cranking first start in the day. I changed the rotor and distributor cap but I don't smell any fuel then all fo asudden it will start. I am wondering is it a fuel relay problem, a fuel filter, or some sort of sensor. when it does start it is very smooth running no shaking or hesitation full of power for the rest of the day starts and stops erands . is it worth buying a plug in code gadget and will this problem show up as a code.
View 4 RepliesChevrolet - Blazer :: 2003 4WD Goes Left Then Right And Repeats
My wife bought a 2003 Chevy Blazer LS 4WD recently and it's nearly perfect except for one quirk. While driving on straight and level roads it will suddenly go left a little and then back to the right. I bought 4 new tires for her and had an alignment done at the same time. The technician allowed me to watch the alignment while in progress. All 4 wheels were connected to a computer and the screen showed the rear was in perfect alignment. The driver's side front was also in perfect alignment but the passenger side was out. That side was aligned and the technician assured me there was no other problems.
On the drive home....it still wandered right then left then repeated every few seconds. I took the Blazer back this morning and they repeated the alignment but it still has the same problem. I have an appointment for Monday morning at a different alignment shop. What might be going on? Everything seems to be tight on the suspension. The vehicle looks brand new inside and out and runs great. It only has 117K on the clock and looks totally original underneath.
