My 99 blazer has been getting hot the past few

Need to change the thermostat! The thermostat is stuck closed. Should not be driving it, getting hot would cause the head gaskets to go. Replace the thermostat. It is rare but sometimes the water pump may be the issue. Make sure it is turning.

I have a 1999 Chevy Blazer, 4x4, 4.3 vortec. We have changed the coil pack, fuel filter, distributor cap and button, the crank shaft sensor, cam sensor and plug wires as well as the ignition control module. We coming to a stop sign it will stall and sometimes when just sitting still. Sometimes it will start right back up and other times it takes several tries. I also have the oxygen sensor on order and it should be here tomorrow. Fuel pressure tested perfectly. No black smoke, no smell of rotten eggs or the cat glowing red. The only code that comes up is PO420. 4 Answers

Have '99 Blazer that is eating up fuel pump relays--about 5 or 6 in this last half week. Pulled cover off one and appears to burned connection wire inside. When goes out, the relay is very hot to the touch. Resoldered connections at pump as well as elect. taped so know they are secured. Still no improvement. Help needed badly. 2 Answers

Had the problem intermittently this past year but nothing like this. Almost every time the car is cut off (sometimes goes out while driving) if will not start, replacing relay will make it start.
