99 blazer crank but no start
 

While driving home, felt a small hesitation during acceleration. Got home, put it in park, then car just died on it's own. Tried to start out right after but no start. Got out, noticed that spark plug wire came off plug #6 at the engine. Plugged it back in but still no start. Changed out that spark plug and wire but still no start. Changed all plugs and all wires but still no start. Got crank, no start.

Haven't checked fuel pressure or coil. Not sure if any codes come up either. Got tuneup about 50000 miles ago.

What do you experts suggest?

Quite simply, check for spark and fuel.

Check fuel pressure and leak down at the service port. Key on, engine off, fuel pump running, pressure must be 60 to 66 PSI and must remain above 55 PSI for at least 10 minutes after the pump shuts off. Post your results.

Typical blazer problem, fuel pump. my mechanic sprayed starter fluid down the butterfly and engine turned over. No sound from fuel pump when I turn the key. Everything else was just leading me astray
