Could a anti knock sensor that is unplugged or defective cause problems with the 305 motor starting?

What does the blinking red light on a Honda CRX ECU signify?
the lights flash in sequence to show dtc's (diagnostic trouble codes)count the #of flashes and that is the # of the codefor example if u r having a problem w/fuel inj. or main relayu should get 16 flashes then about a 3 sec pause then the code willrepeat unless there is more than one code so watch closelyevery 3 sec pause indicates the start of next codeTo find out what each code means, check this table:1) Primary oxygen sensor- Defective circuit or unplugged/ Defective sensor2) Oxygen sensor "B" - Defective circiut or unplugged/ Defective sensor3) MAP (Manifold Absolute Pressure) Sensor - Defective circuit or unplugged/ Sensor4) CKP (Crankshaft Position Sensor) - Defective circuit or unplugged/ Defective sensor5) MAP (Manifold Absolute Pressure) sensor -Mechanical problem/ Disconnected piping6) ECT ( Engine Coolant Temperature) Sensor- Defective circuit or unplugged/ Sensor7) TP (Throttle Position) Sensor -Defective circuit or unplugged/ Defective sensor8) TDC (Top Dead Centre) Sensor -Defective circuit or unplugged/ Defective sensor9) CYP (Cylinder) - Defective circuit or unplugged/ Defective sensor10) IAT (Intake Air Temperature)sensor- Defective circuit or unplugged/Defective sensor12) EGR (Exhaust Gas Recirculation) -Defective circuit or unplugged/ Defective sensor13) Atmospheric Pressure Sensor - Defective circuit or unplugged/ Defective sensor14) IAC (Intake Air Control) Valve- Defective circuit or unplugged / Defective sensor15) Ignition Output Signal - Missing or defective ignition output signal16) Fuel Injector System - Defective circuit or unplugged/ Defective fuel injector17) VSS (Vehicle Speed Sensor) - Defective circuit or unplugged/ Defective sensor19) Automatic transmission lockup control Solenoid Valve- Defective circuit or unplugged/ Defective solenoid.

What does the error code 8 mean on a 1990 Honda Accord?
TDC Sensor (Top Dead Center)defective circuit or unplugged / defective sensor
If you had 4 blinks on your crx 89?
Go to the following web site: http://www.hondacrx.co.uk/technical/faq/errorcodes.htm#2 But, 4 blinks usually means: Crankshaft Angle Sensor (CAS) defective circuit or unplugged / defective sensor Hope that helps.
