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

2000 blazer won't stay running after new fuel pump, new fuel pump relay. New fuel filter. Rebuilt transmission. Still won't stay cranked. Air leak or something

For two week's prior to incident when i shut off the truck i could hear a boiling like sound coming from the coolant resivoir. Radiator was full. But i have never heard this sound before and ive been under the hood for last couple years banging on the fuse box when it wouldnt start. To the current problem... The battery light came on, then it started losing power and shut off. It wouldnt start after that and has been in an auto cocoon ever since. It had light's, and spark. But no sound when turned over. We replaced the fuel filter and my husband's friend tried replacing the fuel pump with a u… Read complete
