Topic: No/low power to fuel pump

[cm3h2o]

Hey alright first timer...
I have a 1987 Toyota 22RE 4x4 Truck that has been sitting in the forest for the last 5 years, pulled it out and am trying to get it to work. New battery, new fuel, new air filter.  The problem I am having now is, the engine is cranking but no fuel is coming down the lines.  I pulled the Fuel line off the input to the fuel filter housing to verify this. 
Things I checked...
- Main relay with an ohm meter....seems to be in order
- Circuit Opening Relay with an ohm meter....seems to be in order, also I can hear and feel it clicking when I turn the key.
- Verified 12v at 15amp Efi breaker
- In the diagnostics box I am only getting .23v at Fp when cranking engine
- Disconnected fuel pump wire connector at fuel tank and checked voltage at connector while cranking .... Nothing
- Connected 12V battery to connector at fuel pump... Lots of fuel flowing out of fuel line that is disconnected from filter so I guess my pump works.

At a loss as what to do next... I read something about the AFM and trying to bypass that?

Any advise would be appreciated.

Thanks

There's a test connector in the engine compartment (drivers side, near the ECU check connector) that you can jump to force the fuel pump relay on (with ignition on).

Just a thought, check the ground that connects just under the center of the manifold.  It might be corroded after sitting or may be disconnected.  Any and all engine grounds need to be clean connections, even the one to the firewall but the non-start is usually the manifold ground.

Hello and welcome. I look forward to hearing the story of how you get this truck running!

My guess is that you have a broken or stripped wire to the pump. At least in my part of the country, rodents have been known to chew on wires, seldom with good results. Also, I have occasionally found wires that came out of their plugs with no apparent cause. As a last resort, run new wires to the fuel pump and see what happens.

Good luck; I hope to hear more about this in the future.

Lewis.

P.S. The Toyota factory service manual is your friend, much more so than a Haynes manual. I believe you can get one from manualslib.com
