Fuel question

[mcammarn]

Just installed walbro 255 fuel pump.
That's it, I didn't do the 12v mod. That will be another time.
After install, I turned the car on the on position, crossed +b and fp to get fuel pumped back to the injector, tried to start the car after I disconnected +b and fp, and still nothing.
Do I possibly have air somewhere? Or what should I look at?
I tried cranking over for 5 so min at one time.
Yes it did run prior to fuel pump upgrade

Update:
I do hear the fuel pump run when I cross +b and fp.
I cracked the fuel line that goes under the intake manifold in the middle, and no fuel coming out.
I cracked the line while crossing the 2 terminals as well

did you bypass the fuel relay?

What exactly do you mean by "cracked" ??

 

[mcammarn]

Mo I did not bypass.
0/3 failure
I unscrewed the line to see if any fuel would come out under intake manifold.

Do you think I hooked the lines backwards by the fuel tank?

If you were to unplug the hangar and jumper the two wires in reverse and get fuel,
Of course that would confirm it. And you might be able to easily de-pin one side of that plug,
Negating the need to drop the tank, if you're feeling lazy(like i probably would).

 

[mcammarn]

So is it possible then I mixed the 2 wires to the pump? Would that have reverse polarity. The pump has power the way I had it. Will it power if I had it the wrong way?

Update:
Pump won't work/ turn on with wires going other way.

So why am I not getting fuel to the injectors then?

Long shot, but make sure you didnt pop the efi fuse.

I actually did! But I put the stock one back on. I couldn't get the walbro to work for some reason. I'll try to figure it put later. I need to put some miles on my engine still. Tommorrow is import face off..lol

 

[supraguy@aol]

You actually did: pop the fuse or check the fuse?

 

[mcammarn]

Pop the fuse. But I had the wiring hooked right the first time I hooked the walbro. The 2nd time, just o see if I had them backwards, it wouldn't turn on at all. The third time I just said f it, put the stock one on for now. It wouldn't turn on, so that's when I checked the fuse to see it blown. Put new fuse, it started right away

Do you................have gas in the tank?

 

[mcammarn]

Plenty, I dropped it with half tank.lol

 

[supraguy@aol]

Welp, i can only suggest that you might have a bad walbro.
