my 92 blazer stalls and wont refire unless i used some ether sprayed into the tbi. new fuel pump, lines, filter, just bought a fuel pressure regulator rebuild kit. not installed yet. any answers of why this may happen? its a 1992 sblazer 4.3 z motor, 5 speed 2 door, 4x4, black. just thought i'd throw all specifics in there.

 

1. Fuel Pressure TBI-11PSI, 2. Idle Air Control Valve. 3. Faulty Injector. 4. Temp Sendor for ECU out of spec. 5 Leaking EGR Valve. 6. Throttle Position Sensor. 7. O2 Sensor. Any one of these items can cause problems you are describing.

 

One thing to check FIRST.
Your ECMB fuse.The connections that the fuse plug into work loose and can cause the fuse to disconnect and reconnect after it cools.I actually had mine on fire several time and it never blew the 10 amp fuse.Melted the fuse and plastic box but didn't pop.
