My blazer will not start it happens when it is cold out side and now it is all the time I replaced the fuel filter check for spark which I have and I can get it to start with starter fluid and it will run great I can turn it off and it will start right away but if I let it sit for about a half hour then it wont start again unless I use starter fluid. What could be the problem?

Check and test the fuel pump relay and fuel pump/oil pump sending unit

Both the fuel pump and oil pump are working what else could it be?

You got spark, fuel but is it the correct fuel pressure if so-check valve and ignition timing.

I went thru the same thing. It was my fuel pump. It take more pressure to start the engine than to keep it running
