Bad fuel pump???

Hey guys, another question for you all. I went to start my 1989 B2 5spd 4x4 2.9L V6 today and she wouldn't fire. Tured over like a champ, but wouldn't fire. I even tried to pull start it wth the ATV, but no joy. I am thinking it is the fuel pump. When I have a full tank of gas, I notice some leaking around the tank (small amount) and about 50% of the time it takes 3-5 seconds of turning over to start the thing. SOOOO, do you guys think that the fuel pump finally had enough and crapped out on me? Within the last 4 months she has new plugs, wires, fuel filter, dist. cap & rotor. Thanks again for all your help.

Fuel pressure test will tell you if you have good pressure to fuel rail. Also fuel pump relay may be a possibility.Can't help with relay location for '89 it's probably along pass side fenderwell near starter relay.You can try turning key to run position do not crank starter. Can you hear fuel pump fire up for a sec? Turn key off and push shrader valve on fuel rail in.Like letting air out of a tire. If fuel sprays up you've got some pressure at least. You should address leak at fuel tank. You can either drop tank or cut a hole in the floor above the tank - for a leak I'd drop the tank , cutting tool throwing sparks and leaky tank= BOOM. Technical Info in this forum is a good place to check for ideas also. Another thought are you getting good spark?

Fuel pump relay

Fuel pump relay is located on the right side engine compartment. Tied in with this is the the EEC power relay in the same area. If this is bad the fuel pump relay will not work. On my 89BII a wire was broken on the inside & worked on & off. New ones cost less than $20.00. I also put a hole in my trunk to get to the tank fuel pump. Than I was able to check the connections for power. I made a plate in the same wavy metal desin to fit over the hole & sealed it with silcone. If it is not leaking back their use auto body tin snips to cut the hole. You still have to drill the first hole. No problem for the past two years with the hole. Some 1950-1960 cars came with an accesss hole in the trunk to get to the fuel gauage sender unit.
