I have a 92 gsr eg that has sat for 5 years. I also changed the fuel pump, fresh gas, oil, and brand new battery as well. I tried to start it but the fuel pump is not priming. When I jump 5 and 7 on main relay nothing when I jump 1 and 7 fuel pump primes. Does this mean it's the main relay?

Thanks

 

My first step would be to check the fuel lines for any leaks or cracks in lines. Do you smell gas when trying to start it? Did you change the fuel filter as well? I would change it if not & it is really easy to install backwards because of how similar both ends are. What happens when you turn key?

 

Problem solved. Sent my ECU to Burton-racing and they did bench test. Although the only thing that was burnt was Q31 transistor, They were kind enough to replace IC17 Chip even though they said it wasn't burnt, but just incase because i explained that my fuel pump was not priming; and Sure enough fuel pump primes now.
