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

I have an 87 blazer 2.8 carberated. It started to die when I came to a stop light and had to gas it with my foot on the brake to keep it from stalling. This I had to do till I got it home and it would not start. I had a har time pulling the codes but the only one I got was mass rir sensor and replaced it. I did a complpete tune up and still can't get it started. I bench tested the EGR and checked the vacume system as much as you can with out it running. It just spits and puffs. The fuel pump kicks in and I'm getting spark and I have 4 times rechecked the proper plug wire to distributer. on the distributor #1 @ 6:30 and fireing order 123456 #1-3 on the pass side, 2-6 driver side. #1,#2 are the front cylinders.. I checked each vavuum hose and cleaned the EVR and EGR from possable carbon build up. I Though timming belt but thwere is no back fire and there is only one person to turn it over and check timing on the crank. Any help would be appreciated. Tom 1 Answer

My blazer was running fine, went in the store and when I came out it would turn over but wouldnt start. I checked the relay and that is fine. Could it be the fuel filter rather than the fuel pump.HELP! 1 Answer

Car was fine, came out of store would turn over but not start. Could it be the fuel filter other than the fuel pump?
