1995 Ford F-250 XLT No Start
Im going to give you guys the whole run down what happened today so we rule everything as possible out!
So recently this is what has happened to me. I was driving down the road and out of no where my trucks engine just shuts off. So I think maybe no gas (can't be, just put 5 gallons in). I have power, but I do not hear my Fuel Pump primping on for 2 seconds as I turn the key. So I went and bought a new Fuel Pump. Installed it and everything was good for about 2 hours... and then it just stopped working again...
(I was stuck at Goodyear) they tested the 3 wires just above going to the fuel tank (Black, Grey, Purple). Black Read .00volts, Grey Read 4.6-4.7volts, Purple Read 4.6-4.7volts. So then they used some test thingy that put volts to the Grey Wire, Read 12.(something)volts and I could hear the fuel pump turning on. So we tried cranking the engine over while they put power to the pump (with the tool they used) and still nothing!
(Tried that multiple times)
So I figured to myself... The fuel pump must be good since its working but its getting not enough volts... Because it needs around 12 volts to run... But it was only getting 4.6volts. So I figured it was the wiring in the fuel pump housing... So I warrantied out the fuel pump for a new one and decided this time to replace the wires that the new fuel pump always come with... So I had to place 2 connectors (The one on top of the fuel pump housing and the one that goes to the fuel pump) I replaced the Grey (signal/power "i think") and Black (ground "i think") wires. I had to cut the Black wire because it was grounded by solder. The wire (Black) that was grounded to a fuel line on the fuel pump housing I had to cut in 2 ends because of how it was like grounded in a split. So I had to solder (My first time soldering, it was a little clumpy but still the wires where stuck on, seemed like a good connection, also gave it a good tug and the wires are nicely on there. Heat shrunk it after) So I plugged the Black wire in the A Connector terminal on the connector that goes to the fuel pump. Thats what the instructions said. And the Grey wire into the B Connector terminal on the connector that goes to the fuel pump. Made sure that the Black wire is plugged into the right terminal on the fuel pump housing connector that has the floater unit (Purple wire) on it. And the Grey wire in its correct spot on that connector also.
Finally I'm happy, that **** to me 2 hours to do. So I put the fuel pump back it and instead of just twisting and taping the 3 wires that I cut to get the fuel pump housing off (wires coming out of the top of the fuel tank). I butt connected and heat shrunk them. Just to be nice and good
Also I was checking the wires and connections on the fuel pump housing and they all appear good. FUEL PUMP IS IN! Also went and bought and new Fuel Pump Relay just to waste money and be on the good consious side! Everything is ready to go!
So I go to turn the power on waiting to listen for the Fuel Pump to prime 2 seconds telling me that I did an AWESOME job and... NOTHING HAPPENED!!
So... Now... this is all I am doing right now

I left it alone for a couple hours and came back and tried multiple times to start it... I HEAR 2 clicks in relay box and a low pop from throttle body.
What in the world can that be

Please don't feel offended, but you are in over your head.
Just connecting wires without verifying where they come from and if power is available when it should be , you have a better chance going to Atlantic City and gambling there.
You should confirm either with a test lite or multimeter what you have when you are supposed to have it. Without knowing and doing that , you are flying blind.
Are you aware there is an inertia sw and how to verify it is set right and working? If not, you might want to read up on just how the system is supposed to work.
I realize you are in need of assistance, but we also need to keep you out of trouble. There is a plug that you can ground one of the connections with the key on and the fuel pump should RUN.. We are playing around with gasoline and be very careful

Thanks For The Reply FINALLY Someone Who Hopefully Can Help Me. I Need some help. I’ve check inertia switch it was down (not triggered) I’ve also taken known good relays and swapped with fuel pump relay (still nothing) I’ve cut the wiring harness and probed to find a hot or ground only getting about 4-6V. I’ve also got a dual tank switch so I can swap which tank is in use. I’ve checked that for voltage and it is getting like 6-8V I’ve also probed the the inertia switch EVEN THO IT WASN’T TRIGGERED!!!! I got 0.0V.

Sorry for 2 reply’s but I’m also wondering what would possibly happen if
I was in theory “driving”
My automatic transmission vehicle dies or stalls out
So I shift from Drive To Neutral And Start The Vehicle WITHOUT stopping or even using brakes.
