Q: Need help! Thanks

asked by on

I have a 1986 f150 302 efi and it hasn't ran for a few years. Parked because of "wiring problem to fuel pump" had new tank and pump put in as well as pump relay but still doesn't have power to pump or tank selector switch. It has spark but no fire because injectors won't let fuel in due to wiring problem. What do I check/ where do I go? It does fire when ether is shit down intake. Please help!

My car has 120000 miles.
My car has an automatic transmission.
