So every day when I first start to crank my blazer, (2001 Chevy blazer 2wd, 2door, 4.3) the motor will turn and turn but not start. If I spray starting fluid through breather and try to start it will crank and run until I cut it off. If it sits for a couple hours it will do the same thing, wont start til I use starting fluid. Rarely sometimes it will crank the second time without fluid. I've changed crank sensor, new battery, cap and rotor, it has ngk iridium plugs, new wires, checked fuel pressure which is at 62, new fuel filter, pump does engage when key is turned. I have fuel, spark, compression. I'm out of ideas. Please help

I have 1993 K Blazer that seems to stall when its hot and humid out... I have put new motor that now has about 60,000 miles on it... I have replaced map,sensor,egr,distributor,plugs,wires,coil,vacuum lines,fuel pump, fuel tank because it had a hole, vents in tank, fuel filter and many other parts and noone can still seem to figure out why i have intermittent stalls... It could be on interstate, at red light, stop sign it just will stall and start back up... It always seems to do it when it is hot and humid or just started because i didnt have this problem over winter or spring... Can someone please help me

Every morning or every other morning i have to get up go out to check to make sure my blazer will start. And as always, its the same thing over and over. Ive bought new battery after battery. I dont know what to do,,,,,,,,,help!

My 2000 Chevy blazer 4.3liter has to keep cranking on and off takes like 20 mins and it starts up and will idle but when you give it gas it will act like it wants to die. Has a new fuel pump, filter, plugs, wires, map sensor, fuel pressure regulator, changed spider, crank sensor even after all that they turn the switch on and off and after about 15 times it will finally fire up and sit there and idle just fine and after it sits about 5 mins and you give gas it acts like it will die then let off and it idles again. Tried to unplug throttle position sensor and could give gas but when let off acted like it wanted to die put back in and same idles but acts like it wants to die and it back fires. What could it be

It starts and runs from a few seconds to a minute then stalls the idler pulley is bad and makes us think it’s causing the alternator to not charge properly. It also sat for a good while before my cousin got it so I’m thinking the fuel pump isn’t putting out the right psi. It also starts to struggle when it’s in any drive gear. We’ve taken the starter off and cleaned it thoroughly, replaced alternator and battery and it ran good for a while it’s got engine noise I’m guessing could be a spun bearing because he’s ran out of coolant twice and his oil pressure drops at the same time. Could mainly use help narrowing it down.

The fuse constantly blows out for the back window/tailgate. It does not have a key entry there, so It’s basically useless as an SUV. Occasionally, a new fuse may last a while, but mostly they blow as soon as a new one goes in.

Had put a large audio system in mine... ended up messing up a relay or we thought, the relay was replaced... ran for a day. The motor turns over but will not start. It is getting gas and firing...

Under the hood of my 1998 chevy blazer in the fuse panel box there is a big fuse that has the letters chmsl on the diagram on the inside of the fuse box panel but there isn't a fuse there where there is supposed to be one. What does chmsl stand for?

Turn key clicks like it wants to start. Donthat one two times and battery goes from 100% to 0% . Grounded to tje frame possibly? Or is my battery to large?

Good afternoon, I would be glad if anyone could help me with my problem. My car had a failure in the fuel pump's fuse, and at the whole fuse box was replaced by a new one. That was the moment when a strange electrical failure appeared. I've already bought three batteries and a whole fuel pump and the problem is still there. It has happened only once that it started and lasted on for an hour and then stalled. I've also changed the coil and the module but it is still failing.

Turn signals keep popping fuses

When I start the blazer the 02 sensor fuse pops.

I purchased a 2000 chevy blazer 4dr 2wd 4.3 v6. I looked up online for the wiring diagram for the stock stereo. And then went and found the diagram for the new stereo. New stereo due to the old one with bose with cd and tape not working. Out with the old in with the new. When i was done. I still had 3 wires that i could not account for coming from the blazer. I taped them off and continued on. With the amp i grounded it and connected the remote turn on from the deck. And with the +12v constant to the amp i saw an open spot on the fuse box just inside the drivers door. Located at the bottom of… Read complete

I went out to drive my 2005 chevy blazer. I didnt hear the fuel pump or the clicking under the hood it makes when you turn it on. It would crank but no starting. So i bought a fuel pump and it still acted the same way. So i get under and checked the body grounds and fixed them. Then put new fuse in started and ran good then came home and it keeps blowing the EMC fuse when i turn on key. Caint quite find the problem. Could it be a bad ground on fuel pump or what?
