I have a 89 chevy S10 with a 2.5 TBI engine. The engine doesn't want to start. I turn key on, fuel pump comes on fuel pump relay cliks 1 time about a second later. Hit the starter, the engine turns over but will not fire. Spray quick shot of starter fluid in the TBI and it will start instantly and runs fine afterwards. I have checked the ignition control module, changed the plugs, plug wires, and cap & rotor. No check engine codes. When turning over the engine no fuel can be seen spraying from the injector. Once engine is started with starter fluid injector will spray a nice cone of fuel into the TBI
