No fuel, but injectors click

[96Turbo]

Hey guys. Back again for some help getting my car to run again - stock redtop

Right after I did the swap, it wouldn't start because it wasn't getting fuel. I thought it might have a weak ground so I started poking around with a wire directly from the (-) terminal. Then magically it just started... and continued running fine without the extra ground I attached. It ran like this with no problems for 2 weeks.

Now it's doing the same thing again. I'm getting spark (runs on carb cleaner), my fuel pump seems to be doing it's job (pinch lines and there's lots of pressure), I know the lines aren't backwards, I've tried pinching the return line to bypass the FPR, etc. When I turn the CAS by hand I can hear the injectors click (and they all have +12V power and a good connection to the ECU).

I haven't pulled the rail out to see if they spray, but I'm pretty sure they're not (plugs are dry). I doubt the injectors are clogged (since it ran fine a couple days ago), i pulled one out and it looks pretty clean. I even tried unsticking them by manually applying power.

Any other ideas?!?!

Clogged filter?!

You can always check if you have some flow on the return line. It will tell you if there is some fuel in your fuel rail. Also, try to get your hands on a fuel pressure gauge... they are like 30$ and you just leave it there after, and it's really convinient to monitor fuel pressure!

brand new filter, but good suggestion. Although the gas tank could be full of shit that clogged it up. But when I pinch the return line it seems like it flows pretty well...

Good call on the gauge. I usually run an adjustable FPR with gauge, but this thing still has the stock FPR.

I don't think fuel pressure is an issue, but I'll try to get a gauge on there tonight

In this order
Tank>Filter>Rail>FPR>Return

ya i'm sure i've got the lines on right. if they were reversed I doubt it would have ran for the last 400 miles i put on it.

however, i bought this car as a shell, which had been sitting for ~1 year. The gas tank could have some crud in it. I've run 2 full tanks through it before it quit. It's possible that it clogged the injectors, but i doubt that all 4 would clog simultaneously.

thanks for the suggestions

I didn't realize you had already driven the car. If the injectors are clicking, and you're confirmed fuel to the rail, then they will certainly be spraying.

well now i feel stupid... it turns out the fuel lines ARE reversed

it's weird though, the filter inlet hose and the return hose are connected to the correct hardlines (reversing them here would put weird bends in the fuel line). Also, the lines connected to the fuel pump seem to be correct (once again can't really switch them without messing up the proper routing).

So what does that leave? The lines are mixed up between the fuel pump and chassis hardlines? I'm assuming if the voltage were reversed it wouldn't pump at all (or try pumping back into the tank)

any ideas?

I'm lost....so you're saying your feed line goes to the right connection(forward of engine) on the fuel rail and the return is on the rear connection?

Maybe its the alcohol in me lol

[96Turbo]

^lol yes, that's correct. And the lines on the pump seem to be in the right place too.

But the return line get's pressurized and the feed line doesn't...

[EsChassisLove]

ok so the feed line has no pressure but the return line does....

Now where in the book of sense does that make any lol

[96Turbo]

meaning they're clearly reversed

[EsChassisLove]

stock fuel rail or aftermarket?

[96Turbo]

fuel lines were NOT reversed. It ended up being a loose connection on the grey chassis plug. The red wire (ECU Backup Power) also powers the fuel injectors. They weren't getting enough voltage so they were just sputtering and not firing correctly.

I bent the female connector a little bit to make better contact and it fired right up! Such a simple fix after swapping out fuel pump, injectors, fprs, etc.

Thanks dudes

Thanks for letting us know!

Good to see it works right now!
