Starting neglected vehicle
Posted 16 December 2017 - 10:22 AM
The engine is turning over but not firing.
There is clean (but old) fuel at the filter and also at the injectors.
The plugs are clean and sparking.
Is there something I've overlooked?
Anyone have any tips?

Are sure the fuel is really good? Does it smell clean or a sicky sweet smell? 10 months (assuming fuel was fresh was car last ran) seems like a stretch without using fuel stabilizer.

I had some starter fluid and was able to get the engine to fire. There was very little left (I'm in a somewhat remote location) and I'm now trying to start it by spraying WD40 into the air intake without a result. I would have thought that even if the fuel was old, the spray would combust.

When you first turn the key on, you should hear the fuel pump run for a few seconds to build pressure.
If you hear it run, you should have fuel coming out the filter hose.
You can always pull the air box off the throttle body and put a cap full of fuel in the throttle. Put it back together, it should start and run for a bit.

It's often a wiring corrosion problem between the relay and the fuel pump connector.

... The pump is works but is getting no power ... Any clues?
Remember that the Power for the fuel Pump is cut off, if the engine does not run; so there will be Power on the wiring for the fuel Pump, only few seconds after turning the key to the "ON" position.

It had to be the one with the green plug, damn it! Why did they have to hide the fuel pump relay in such an out-of-reach spot. Well, I eventually got it loose and it's showing 70 ohms and making an audible click when energized.
As for the fuse, it's not in either fuse box and I haven't been able to open the '98 Legacy FSM which I downloaded. Where else could that fuse be hiding?
I bridged the connection on the green plug and my assistant couldn't hear the pump whir.
So, fuse or wiring? what's the next step? do I start checking continuity between the relay and the pump?

I've tried setting it up like this and quickly trying to crank the engine over but now I can't even get it to fire, even with a cap of gasoline in the throttle body.
