SOURCE: E.E.C fuse keeps blowing in 1991 Ford Explorer

if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing

sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

SOURCE: 1996 windstar relay

The fuel pump power on the Windstar is controlled by a component called a Constant Control Relay Module (CCRM).
Its located located on the driver's side of the engine compartment.d7fb0ae.jpg

SOURCE: fuel pump location and replacement

You are looking for the constant control relay module- ( CCRM ) see below. The pump will be located inside the fuel tank.Most of the time , its the pump and not the relay but, it wouldn't hurt to check the relay out. Teh relay is housed in the CCRM. Its located behind the engine coolant reservoir.

SOURCE: 2008 Ford F450 fuel pump relay fuse keeps blowing.

the fuel pump and radio are not on the same circuit, most liokely the fuel pump is shorted, that is the most common cause, get under the truck and disconnect the fuel pump connector at the tank, if the fuse doesn't blow then u need a new pump.

My 1993 E-350 club wagon wont start Code: 542 =

Replace the TCM to fix the converter clutch problem.. The line 12 volt is direct power from the battery and 7 volts out the I am suspicious off as I think that the coil for the relay is partially shorting out to give the 7 volts. As for the other wire 12 volts in would be ok but if there is nothing out unless it is a relay that has not closed because the relay coil has not activated correctly.. Check the readings against a new relay.

30amp auto shutdown fuse blows is it alternater

The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements. The Fuel Pump Relay is a separate relay controlled by the ASD relay input to the PCM. Fuse #12 (10amp) provides 12 volts to the coil side of both the relays and the ignition switch. Fuse #6 (30 amps) supplies 12 volts to the output side of the relay. Fuse #16 (15 amp) from the relay output to the Oxygen Sensors and Fuse #26 (15 amp) relay output to the PCM. Fuse #24 (20 amp) is Fuel pump relay output to fuel pump. Fuse #19 (10 amp) supplies 12 volts direct to the PCM.
look for burned or melted wires in the offending circuit.
sounds like you wiggled a wire while installing new relay.

Replaced fuel pump now no power to pump

If you unplug the connector for the pump, you should have battery voltage on the pump circuit from the relay for 3 seconds. You would have 5 or 6 volts for the gauge sending unit.
You should be able to jumper the pump relay and get 12 volts at the pump connector.

2000 chevy silverado 1500 4.8 4wd will not start

Your pump is controlled by the pcm using a 12 volt signal to the relay. Pull out the relay and probe the relay socket with a voltmeter. There should be 2 terminals with 12 volts when the key is on. With the key off, there should be one 12 volt terminal coming from the ecm b fuse. See top left of diagram below.

No fuel coming to the fuel rail. is it a relay, or fuel pump problem

  1. Check the power going to the fuel pump. If it gets around 12 volts when the key is turned to the On position, replace the fuel pump.
  2. If the fuel pump is not getting around 12 volts, check and replace the fuse for the fuel pump.
  3. If the fuse is fine, replace the relay for the fuel pump.

Pull the relay and make sure you have 12 volts there. Pin # 30 is the power to the pump. this will tell you which way you have to go to find a short or corrosion in the wires. let me know

Replace the oil pressure switch for the third wire on that sends 12 volts to the fuel pump upon turning the ignition key on to prime. Once oil pressure is achived the computer shuts that circuit off and turns on the fuel pump relay to power the pump till you shut off the engine

Check for 12 volts power at the fuel pump harness. If no power is going to the pump, check the fuel pump relay. Also, check the fuel pump inertia switch. Ford usually has it on either inside left or right rear trunk fenders.

On my 1994 plymouth voyager the 3 wire harness to fuel pump (blue wire) doesn't have 12 volts; should it? fuel pump quit then worked once when hot-wired with 12 volts. fuse and relay is good.

The wire should not be hot until the relay is triggered. The relay does not get triggered until the ignition key is turned on. It will run for 3-5 seconds or until the system pressure it at max.
