Final steps to my 5.4 swap, please help with fuel system.
I have been working on and off for 4 years on a 5.4 swap. The car is a 1998 GT, and I have placed neatly a 2002 expedition 5.4. I had the engine running, and did a break in phase. I was loosing oil pressure, and had a clutch squeak issue. So I pulled the motor, upgraded the oil pump, and replaced all the clutch moving parts.
Dropped the motor back in last week, it is now 100% back together! No nuts or bolts left, lol.
Go to start it up today, and nothing. I am getting no fuel at the fuel lines on the rail.
- Checked the interrupt button, and it is pressed in, tapped it till it popped up, then pushed it down.
- Checked the 20a fuse in the engine bay and it is good.
- Cut off the fuel filter (did not have ford connectors, instead it was a previous hack job). The lines were totally dry.
- With the lines disconnected, I had the key turned to the on position, and no fuel came out, nor did I hear the pump.
- Tried to turn it over, with the line held in a bucket and nothing.
- Unplugged the plug under the gas tank, and checked all the pins for power, while my GF cycled the key from off to on, while I was testing. I looked for full and micro voltage, and saw no fluctuation.
- I can feel the relay in the passenger side wheelwell clicking when the key is turned to on. (it clicks more than once per keyturn, it is not simply, on click, off click. It clicks maybe 3 times or 4 every cycle.)
- I can see voltage at the plug on the bottom of the emergency button.
I still do not have voltage at the plug under the bumper at the gas tank... To test the fuel pump, is there a way that I can hook the battery up to the plug harness and force the pump to come on, to check its operation? Will I break the pump with battery amps? Does anyone see anything above that stands out, including the clicking relay, I do not have another mustang around to compare it to?
Here are some vids just for show! I got a lot of help on these forums when I did the build, including a great seller that gave me some awesome parts! Perhaps this is the final challenge!!!
Pre-tune, first start,
