havin a lil trouble

95 s-10 blazer 4.3Vor. low rpms/ idle engine begins to stall out & rpm gauge bounces around. when i rev it it runs normal an rpm gauge bounces a lil. stalled 3 more times an now wont start at all. sat a day an no restart

has the truck sat for a long time before this happened? If yes how much gas was in it?

When no start check for lose of spark to all plugs or lose of fuel pressure.
Post back what it is losing.

It didn't sit before.ben drivin every day. Took it to off-road shop to get work done on mon. Got it back wen. Haven't been able to start it sence. An I can hear the fuel pump kick on

What was done to it?
Is starter cranking it good?
Got spark to all plugs?
Just fuel pump running does not say you got fuel pressure.
If you have good spark check fuel pressure and post back and post back reading.

We need info to be able to help.
