7. This test will determine if the distributor module is not generating the reference pulse or if the wiring or ECM are at fault. By touching CKT 430 with a test light, a reference signal is being generated. If the test light blinks at the injector, then the ECM and wiring are OK.
8. If the ECM is seeing a high TPS voltage it may be in the clear flood mode. Disconnecting the TPS will allow the ECM to use a default value and turn the injectors on. If the TPS ground wire and connections are o.k., the TPS should be replaced.
