Why my 1999 Chevy Blazer 4.3, engine starts, runs about 5 second, dies and then won't start, if you wait 10 minutes it starts and runs fine, this happens once every few weeks/months or twice in one da


You may be having an intermittent failure with the fuel pressure regulator - checking the fuel pressure when the truck won't start may pinpoint this problem. If the pressure looks OK, this same problem can be caused by the ignition system as well (ignition coil or control module).

My car hard start then dies after few minutes in idle


Sounds like a fuel problem. Dirty fuel. Or a leaking return pipe. Possibly a blocked tank breather

1997 Buick LeSabre stalls out while driving will not restart


This could be caused by a bunch of thing's , fuel system , engine sensors , ignition system , PCM etc.... Testing is the way to eliminate guessing . Viewing scan data is the best way to diagnose these type problems .
047 Engine Hard to Start or No Start Scan Data for Ignition
048 Engine Hard to Start or No Start Scan Data for Starting Problems
002 Fuel System Tests Start Here

Your best bet take it to a qualified repair shop .

Hard to start after shutting off


The starter operates great when cold. When the engine gets to its normal operrating tempreture the starter gets hot. An old starter will have an expanded armature from this causing the starter to drag or just freeze up hot . When its cool it will start again. This will eventuly get hot and the armature will go bad forever on you so get it changed soon

Hard to start engine hot or cold


Possibly fuel pump losing pressure or leaking down. try changing fuel filter and try cycling ignition a few times and see if that helps build up fuel pressure. I don't know what engine you have so this is best I can do for now. hope this helps

Hard to start when the engine is hot


Sounds like electronic ignition problems, I had a truck and it started doing that and then it would not start at all hot. You would have to wait for it to cool completely, then it would start right up. Ignition module problem is what it sounds like.
