FUEL PUMP?

1983 Honda Prelude

Electrical problem
1983 Honda Prelude 4 cyl Two Wheel Drive Manual

My dad has a 1983 Honda Prelude. It hasn't cranked in about five years but his other car has broken down and now we are trying to fix it. We noticed when you spray starter fluid in the carborator it will crank but only while you're spraying it in there. So, someone told us that we probably needed to drain the gas, put new in and if that didn't work to get a new fuel pump. We did that, and we got all new filters. It still would not crank. Well, when you unhook the gas line and turn the key on, gas does not shoot out, like it is supposed to. We got to looking on the internet and it said something about a fuel filter cut-off relay or something but it's kind of expensive so we were wanting to know if we're even looking into the right direction or if we're completely off. Please help us.

Hi Nikkixbby00,

Fuel pump is located under vehicle, below the left passenger seat, just behind the tires. Quitely the fuel pump has failed due to inacticvity over the years.

Remove the cover for the fuel pump and disconnect the wires, Attach a test lamp and check if it lights up when ignition switch is turned on. Crank the engine and note if the test lamp lights up. If lamp lights up, apply battery voltage to the fuel pump Black/Yellow wire and ground the other wire. If fuel pump does not work, it is bad.

I know where the fuel pump is, we've already taken it off and put a new one on. So how in the world would testing that new fuel pump get us anywhere. We already know it works, it's brand new! We were just wondering if the cut-off relay could make the car not run?

You were supposed to test if power supply is getting to the fuel pump but nothing was mentioned about it.

If power supply is not getting to the fuel pump, how is it going to work even if it is a new pump?

Of course the fuel pump relay would cause non starting if it is not getting the fuel pump to work.
