In failure, there was success

This is what awaited me in Tampa. After driving 3 hours I was ready to get to work to be able to drive this POS to Daytona. And at first, it was going to work.

As we tore into the car to replace the fuel tank and pump, we ran into a few problems. First, was that the tank appeared to be slightly different from our previous car even the they were both ‘85s. But all the holes, bolts and hoses aligned. Or so we thought.

In the end, there was just no fuel pressure. We absolutely could not figure out why. The pump ran, the car cranked. All lines were hooked up. But it just wouldn’t get fuel. And yes, we put fuel in it.

So, today I drove back to Tampa. This time that car was coming with me. And I got to drive a brand new vehicle. Something I rarely get to do.

Welcome back to the 300zx world. Fuel filter might help a little. Could also potentially be injector issues.

I really don’t get it. We installed clear lines to see if fuel was even making it out of the tank. It wasn’t.

Our tank was also spotless when we brought it, with new fuel filter.

Ahh mid 80s Nissan ownership you never know what part you need. I had a pulsar that was not a turbo but had a lot of turbo parts on it for some reason. Turbo fuel system, turbo electrical system but no turbo.

Fuel pump is wired backwards

I know you stated new pump, but is the pump itself confirmed good?

Also; return style or returnless fuel system? I’m guessing return style. Sounds like you have power everywhere so your culprit is either a fauly part or cracked line. Cracked line would give you at least SOME gas in most cases. Think a sputter to life and die scenario....

Yea, the pump worked just before we pulled it out of the old car, because we used it to dump the gas.

I’m thinking it needs some pressure in the lines to start sucking fuel, so today I’m going to try ether in the throttle body and see if it will suck some fuel.

That’s what this car looks like too. P/O was convinced this was a super special car that should be completely restored.

Is that a thing that can happen? We just plugged the plug in like the old one.

You need to prime it. I had an 86 Pulsar that had a bad check valve in the fuel pump. The gas in the lines would empty back into the tank if it sat overnight. I would have to spray gas into the carb and crank it each morning to vacuum fuel back in the lines, and to the carb. Then it was fine for the rest of the day. You could sit there for 15 mins trying to crank it, and it would not prime itself. I had to spray gas and have the engine running to get fuel back in the line.

That’s what I thought was happening, I’ll try it tonight.

Yup....you never know. If you hear the pump running but get no fuel out...you have your culprit
