While driving my '95 Chevy Blazer (4.3L V6) on the highway, I pulled off to use a rest stop. The engine was (and has) been running/starting well, and upon returning to leave, the engine would not start. The engine was turning over, but would not ignite. Here's what I know:
- Battery is good, (even tried getting a jump just in case)
- The fuel pump is active, (I can hear the pump when turning key to on position, and verified there was some pressure using fuel rail schrader valve - I didn't have a pressure gauge to deteremine how much pressure there was, but it was pressurized)
- All 6 spark plugs, engine oil, tranny fuild, air & oil filter were replaced last month.
- Ignition Coil is sending spark
Any ideas what could be up with it?
Thanks!
