The current in a really parallel circuit flows along each parallel branch also re-combines when the branches match again. If you have to splice in new wires, they must be marked for future reference. This picture 1988 Mustang 5. Drilling specialist Darrell Kunda blew some holes in our inner fender to mount the bulkhead fittings, and then we just connected the dots with the fuel hose. We used a vice and open-end wrench to fully seat the fitting. There were 14 under dash connections that needed to be fed from scratch or spliced into the main vehicle underdash harness.
With Hypersilver, almost everything is electronic, including the fuel supply. Making the hose ends is the most daunting part of this install. To get some idea of what a good reading is, short the two meter leads together and observe the reading. Excellant idea to lower the bracket and use the top to mount components. Fuel Pump Relay Circuit Descriptions The Ford fuel pump relay has 4 wires that connect to it. Taking the time to fix now will save time later.
I'm going to try tracing the wires one more time and see if I can find anything. Fuel pressure at rail when idling is 30 psi. The sleeve is the first part to go on. Hope this helps, i saved the link for future use if i need it, might be a good idea for you too. I think I'm going to order a new harness and another relay 2 and see what that does.

As right now its not charging but the light isnt on. Please scroll down to view more images. For me, I felt that the best way to know my car and my system was to touch every wire and understand it's function. Probe computer pin 22 with a safety pin and ground it to chassis. Also the white with black jumper from big to small alt connectors only had 1 strand of wire left lol. Most of the time , its the pump and not the relay but, it wouldn't hurt to check the relay out. Description for 1988 Mustang 5.

Remove vacuum line from regulator and inspect for fuel escaping while pump is running. Study these two websites in detail to see how the harness and sensors work. First, when I turn the key the pump does not prime. The computer will throw error codes for this but that's ok. The chassis ground is up near the spare tire shell.
You will have to drop the tank to inspect the pump power and ground connector and the pump wiring chassis ground. Keywords for 1988 Camaro Fuel Pump Relay Location :. The electrical circuit for the fuel pump has two paths, a control path and a power path. Draw connecting wires as direct lines. Good Luck here is the link.
After the electrical functions have been verified, the harness lengths were adjusted by routing and cutting out excess wire lengths. Or, you can leave the wires and install resistors in line to trick the computer using. Fuel Pump Troubleshooting for 87-90 Mustangs Clue — listen for the fuel pump to prime when you first turn the ignition switch on. The following photos detail the installation: Assembly of bracketry: Bracket was formed up from 18 gage sheet stock using this ; graciously designed and passed forward by Jason5.

I believe I already mentioned that it looks like that's what your missing. Due to it's proximity to the battery, it may become corroded by acid fumes from the battery. In a parallel circuit, each device is directly connected to the power source, so every device gets precisely the same voltage.
I copied the wiring table to a spreadsheet and made a checksheet so I could verify each wire correctly. The connector I had was cracked so I chose to disassemble and replace. Today we are pleased to declare that we have found an incredibly interesting niche to be reviewed, namely 1988 camaro fuel pump relay location. I have a bunch of pictures that I can post if that will help also. I fed the harness from under dash outward, as this was the smallest amount of wires to move.
This ground causes the relay coil to energize and close the contacts for the power path. I'm lost as to what it can be. Tripped inertia switch — press reset button on the inertia switch. Ok here is an update of sorts, I still am not sure what the 3 wire connector is. Do not forget to share and love our reference to help further develop our website. It contains all of the programming, and when commanded according to predetermined settings, sends signals to the power cells, which then send power to the components. In particular, you will be changing the lengths and locations of connections because much of the loom was routed to the front left side of the engine bay battery location of a Fox Mustang , and you are relocating to either right side or under dash.
