Question about 1994 Chevrolet Astro
Looking for any other checks I can do before assuming the ECM is bad.
Too much gas flowing to the throttle body from the fuel injectors. With both injectors in place, van stalls. If I remove either injector, van runs smoother, but not as it should.
Van has a TBI fuel injector. I have changed fuel pump relay. Good spark in the plugs. Catalytic converter checked - not clogged. The Check Engine Light is not displaying on the dash. I have not been able to get an error code to display when checking the assembly line data link.
Check harness to the injectors seen aot of these where the harness gets short to grond at the base of the throttle body to air cleaner and they saty wide open! check that harness!
