Intermittent Fuel Injector Question...


Recommended Posts

'92 loyale did run smooth etc.with 125K/mi .now it will not start, and I don't smell any fuel on the plugs and the throttle body also has virtually no smell of fuel..now once out of many starting attempts will I find some fuel in the TB..if the car does start, the injector is intermittently working when raiseing the RPM but seems to run smooth at idle, but with a lower rpm then normal..and then it will suddenly no longer run...my newly aquired HF fuel pump tester shows the FP pressure to be at 21psi, taken just before the TB.(spec for NA)..Can the ignition switch and crank sensor work occassionly, or is it, when they fail do they fail completely..would the same apply for the ECU ??
