Blazer stalling problem
 

Ok so I'm new to this and I have been searching the forums but I figured I would jump in here and give my exact problems specific to my situation to get the best results. So I was driving it a month or so ago and it started to act rough upon start up. When I put it in gear it stalled out and would not fire back up. So since then I go to start it up every once in awhile and it still won't turn over, unless, I put it in neutral. Then sometimes dies again once I place it in drive. It is a 95 blazer 4x4 with 180k miles. So if anyone has a clue where to start please let me know.

when was your last tune up? what shape are the plugs wires cap and rotor in? any codes? have you checked the nutural safety switch, and of course are you getting fuel?

Last tune up was about 6 months ago. They aren't in bad shape. No the CEL isn't on. How do I "check the neutral safety switch" also would that affect it dying when I put it in gear? And yeah I'm getting fuel.

neutral safety switch is on the linkage however could also be a vacuum hose to a smoke test will check for that

Has anyone else had this problem? I know it's a 95 but if it were a vacuum leak wouldn't the check engine light come on? I have no check engine lights and now I can start it up. It has no problems at idle, it stays perfect at around 800rpms. I haven't driven it since it stalled and left me stranded when I put it in gear. With no cel could it just need a tune up and fuel filter?
