Question about 2003 Ford Expedition

3 Answers

2003 Ford Expedition - Alternator, Starter, and Battery tested good. I was told it might be the starter solenoid that is on the fender. I don't see one, does anyone know if it exists or where it is? I didn't think this year Expedition had one but it's on the parts list for this 2003 and says mounted on fender. Truck starts hard like it has low battery. Sometimes starts fine. I pulled the battery put it on charger and charger said battery was at 50%. Put battery back in and and it started hard 3x.

You have a bad battery, Fords especially need a big good battery. The solenoid is mounted on the starter and when they go bad no matter where it's mounted it will "click" and not turn the engine at all. When you replace the battery get the biggest CCA rating that fits. I hope this helps. Take care.

Well first have you charged your battery back up, if so then try to by pass the ingintion switch by just connecting the two main post of the colenoid with a piece or wire, this creates a direct wire basically from your battery to your starter, if still no luck you will need a new starter located more to the drivers side close to right under the pedels on the bottom side of the truck.

You will need new igniton cylinder. Sounds like you have a short in the cylinder.

SOURCE: 1977 ford f 100 solenode mounted on starter

If memory serves me this truck comes with a starting system that incorporates an external solenoid mounted on the fender wall. The symptom you describe is related to either frozen contacts in the solenoid or the existing wiring is attached in correctly. The way the external solenoid wiring goes is as follows, positive battery cable to the solenoid (large, post doesn't matter either side) then the long large wire goes directly to the starter, this type of starter has only one large connection on it which accomodates the large wire from the said solenoid. There are two small wires some where in the vicinity of where the solenoid is mounted to the fender wall, the wires are identified by there special rubber capped shape one is black and one is red, the solenoid shoud have a + and - mark right on the cast to identify which post the wire slides onto. By your description the starter has asolenoid built onto it. Just run the single solenoid cable wire as I decribed to that starter and disconnect and tape the positive small wire going to the starter. Proceed to connect the two small wires that are located in the vicinity of the fender mounter solenoid to the solenoid as I decribed they should have a round rubber slide over type connector to accomodate the small solenoid posts. If this doesn't work you probably need to aquire a starter that is non solenoid intergrated starter, be sure the solenoid is good, that is the one mounted on the fender wall, the described solution should work if there is power to the positive small cap type red wire when the ignition key is activated to the start position, to check put a voltmeter on the wire while an assistant activates the key the volt meter should read 12- 14 volts only when the key is actived to start.

2000 expedition no crank

try to turn the motor over by hand. If you can't. Remove the serpentine belt and you'll most likely find a frozen alternator or water pump or something.

2003 ford explorer wont start hear a click under the hood, i tried to jump it and it wont start. do u think it needs a starter?

Go under the car and have a helper hold the key in the start position while you probe the wire to the solenoid for 12 volts, also do a voltage test on the positive battery cable and inspect it at the battery for acid intrusion near the positive battery post clamp, if acid has gotten into the cable the outer insulation will appear swollen and the cable must be replaced, this is a common cause of no starts on Explorers.

I try to start my truck up which is a 2003 ford expedition and it makes a ticking noise! well i jus changed the starter and its still making that noise. could it be the alternator or whats the problem?

The starting system consists of:
  • starter motor
  • starter switch, part of the ignition switch
  • digital transmission range (TR) sensor (automatic transmission-equipped vehicles)
  • starter motor solenoid relay switch
  • starter solenoid
  • starter drive
When you turn your key to start your engine, it just clicks, right? If so, more than likely this is due to a bad battery. Even though your battery may appear to be fully charged, it may have a dead cell, or worse. If you get a jump, does the vehicle start? If so, replace your battery.

Possible sources of the problem if the engine does not crank or the relay clicks:
  1. Battery
  2. Starter motor
  3. Starter motor relay
  4. Ignition switch
  5. Damaged fuse
  6. Anti-theft system
  7. Circuitry

I recently changed my battery on my 2001 expedition and now I have starting problems and I don't know what to very random but today I would assume it's the temperature...any suggestions

Could still be a number of things. If the jump works, first order would be to get the system checked. That would eliminate a couple of possibilities of alternator, battery, and wiring. It allows all the items listed to be tested under a non-load and loaded condition.

If those are good then start leaning towards the starting system. Starter/starter solenoid, ignition switch on column.

Never hurts to have a battery charger around or one of the new starter amps that are available.

Cant find fender, or firewall mounted starting solenoid

Follow the thick wire from the starter's solenoid, back to the battery, if there is a unit with 2 connections (inline with the wire) then thats the second solenoid.

There are 2 relays or solenoids as they called on a starter, one is on the inside of the fender under the hood, follow the positive battery cable, the other is on the starter, both do the same thing, later years only have the one solenoid on the starter.
