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

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

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
