QuestionPreviously you suggested that I drain the tank, change the fuses and try again to start the car. I did this and don't appear to be getting fuel to the engine as I can get it to run for a few seconds by pouring gas in the carb or applying starting fluid. What would you suggest now? Is there an accessable filter?
AnswerFuel pressure at the engine must be tested at this point = should be roughly 75 PSI.
#1. Fuel Pump Relay bad?
#2. One or both Fuel Pumps bad?
#3. The Reference Sensor may not be sending signal?
#4. Overload Relay or relay fuse may not be passing signal?
#5. KE Control Unit may not be processing signal?
