CHEVY , NO SPARK OR FUEL TO TBI

1989 Chevrolet Truck

My father a 1989 Chevy Truck with a 350 engine, maunual transmission and 250,000+ on the speedometer. He sudenly has a no spark and no fuel to TBI problem. The engine cranks over so not a battery problem. I checked and replaced his dist. Cap, coil and the ignition moduel but still no spark and still doesnt uncover why there is no fuel going to the TBI though the fuel pump is working. I am thinking the ECM went out yet need another mechanics opinion. Thanks for any additional ideas on what is causing this.

Three things,

1. Fuel pump fuse- passenger side firewall in a fuse holder

2. Fuel pump relay- next to fuse

3. Bad oil pressure switch possibly will cut fuel to TBI

Check these
