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

Iwas having trouble with it starting. I replaced engine control modgule two weeks later it went out again I relaced it again. Oneweek later it lost its spark again. This time I had two change out coil pack. Now while I'm driving it dies. And it stsrtes right back

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.

Cranks but no start. Didnt have spark. Changed coil and ICM now have spark now but no start. Fuel pressure over 61 psi. No codes.

Ii have a 1999 blazer it just died on me after sputtering and I barely made it home. Next morning no crank no start. Replaced coil and ignition module and started after I put my test light on the crank fuse which grounded it out. Since then I've replaced everything only to find I have a parasitic draw wich turns out to be a direct short somewhere. The plug under the fuse box has 13 slots going to ground that shouldn't. I removed the block from the fuse box and my short at the battery cables went away. But after vmback probing the plug it's still grounded out somewhere. Should I just change the harness?

I've reworked my fuse block and no I'm having a no spark/ no fuel prob. This vehicle was running prior to my working on the fuse box. Checked the coil, ign. Mod. Pickup coil is everything looks good. It must be a prob. With my wiring @ the fuse box??
