Ford - Explorer :: 2002 Won't Start Or Crank (even Manually)
Dec 8, 2012
I've been working on this explorer for a week now and I figured it's time to ask around. My explorer won't start/crank, I've replaced the starter, battery terminals, tested voltages/amps/relays and fuses, still nothing. All i get is a heavy clunk, like the starter is engaging but the flexplate won't budge. It's a 2002 4.0 xlt automatic.
I'm fearing the engine is seized as I've tried manually turning the engine with a socket on the crank pulley bolt and even with a breaker bar I can't get it to move. The thing ran fine a week ago and I can't imagine this thing would seize at barely over 100k miles, not hydrolocked or anything I can think of, are these engines prone for spontaneous seizure or am I missing something?

So my 2002 ford explorer with the 4.0 L V6, has been cranking along time before it starts. I thought i had this figured out already, i put a brand new fuel pump in it from the ford dealer. That seemed to work, but the problem came back.
Especially when it is cold, it cranks a lot longer than normal to start. and when it does start RMPS go way up briefly and come back down. Seems to only act up when its cold out, say 35 degrees and lower.
So the remote start wont work because it only cranks for a few seconds and then stops. it tries this three times and it gives up. i go out there to start it and cranks for 10 seconds it seems like, sometimes i have to feather the fuel pedal.

I've got a 2002 Ford Sports Trac that won't start ! It will crank till battery dies but is not getting fuel. I have had it towed 4 times in the past year. of the 4 times,this last time it wont start. Every time that I have had it towed back to my house and dropped in the driveway it has started up with no problems. It will run for a few months or more.This last time it would not.
Could this be an electrical problem.Maybe loose ground somewhere or something else. Would like to rule out some things before investing in a fuel filter or fuel pump. Would hate to buy new FuelPump and that not be the problem. Can't find free wiring diaghrams for this issue.

1999 XTL 4.0 auto, was doing fine, replaced Interior light bulb, now wont crank over!!! i suspect the anti theft system... how do i fix or ByPass the security system, i can start the truck by Manually engaging the starter Relay under the hood.

Kids called and said the battery was dead, truck would not crank over. 2002 EXP 4 L. Drove 90 miles and checked battery to be o.k. Changed out with my truck to double test... no crank. Decided the starter must be bad. Banged on it with a long pipe from above - no start.
Winched onto a trailer and brought it 90 miles home. Winched it off and pulled to the garage. Looking from above i looks like this is a straight forward solenoid / starter / hot wire to the battery. No switches/ etc in between. Though i would try it one more time ... clicked key on and off 3 times and truck started on the 4th turn.
Tried it 6 times over 2 minutes and it started every time.. I am thinking the starter and solenoid don't owe me much after 11 years and 165k miles. Plan to check the cable and ends also.... Just wondering an specific known problem with the starter / cables before i jump in.

We have a 94 ford explorer and every now and again it has issues on the start up. It will sound like it will want to crank over but just won't. If we wait 20 mins it will start up no problem. We have changed the fuel pump, fuel filter, ignition coil, and fuel pump relay but it still has this problem. Also occasionally the a/c blower wont turn on. Tonight it happened again and I pulled the fuel pump relay out and it was really hot, after it cooled down and was put back in the car started. I am beginning to think it maybe an overheating issue that is affecting the relays but am not sure. I was also wondering about changing out the relay box...

I have an Explorer Sport 2001 that will not crank nor start. I have replaced the following:
Crankshaft, camshaft sensors
Ignition coil
Ignition switch, neutral safety switch
Fuel filter
Fuel pump
Starter
The battery is less than 6 months old .. Still, the car will not crank, will not start. I have spark, voltage and fuel.
The PCM does NOT communicate with the scanner. I purchased a used PCM off of eBay. This one does communicate with a scanner and gives the following DTC codes:
P1120-- Throttle Position Sensor out of range
B1601-- Unprogrammed Pats Key
Since the car is in the Caribbean I can't tow it to a dealer.

Picked up a super nice 03' as is with a no start. It cranks over nice and smooth, sounds like it has proper compression, and has proper fuel pressure. Tried spraying either in it and it will almost catch.
Tried putting a known good coil pack on it, no dice. Usually when other engine slip timing chains, it will crank rough, like a few cylinders are zero. This is not the case.

I'm working on a 1997 4.0 ohv and it has a hard start condition on first start up. any after that it will just be a crank no start condition unless you hold the gas pedal to the floor. Replaced the camshaft actuator, plenum gaskets, coolant temp sender and thermostat, fuel pressure is normal.

I have an 04 Ford Explorer XLT 4.0 Flex Fuel. There has been loss of power to fuel pump. Relay and fuse both good, replaced the inertia switch...still nothing. Could a FPDM (fuel pump driver module) have anything to do with this issue? Or what should I check next? I am definitely at a loss as to what the issue could be! I know it is fuel related because I used starting fluid and it started right up and run for just a few seconds, so that should rule out ignition I think.

Sometimes after running my 94 Limited, it doesn't want to start - it does crank - like it's not getting fuel. I have found the work around and want to know if it would be fixed by replacing the fuel pump relay.
The symptom is just after starting, it starts to run poorly, and then dies out, then will not start at all. I use to keep trying to start it for 20-40 minutes and suddenly it seemed to work.
It seems the work around is to turn the key to on for about 5 seconds and then turn it off - then it starts and runs as good as ever.
So, is this a symptom of a bad relay? I thought I'd start there because of the cost of the relay is fairly cheap. 1994 Explorer Limited 4x4?

I have a 2002 Explorer 4 door with the flex fuel V6 engine with 157k miles. This has happened twice in a month. You got to start the truck and it starts to crank for a second and half and then it completely stops for a half second and then starts cranking again and fires up. The kicker is after it did this the instrument gauges, all of them, stayed at nothing when it started and then they all at the same time went to the highest level and then they all dropped back down to nothing and then rose to their perspective positions. My trip gauge reset it self to zero as well..

1995 Ford Explorer, 4 ltr. engine, pushrod. Will not start. Replaced fuel pump, fuel filter, every relay, pressure regulator, and the crank position sensor. I realize there's a whole bunch more parts under the hood, but I am ready to give up. Before the fuel pump would not run. Reason for replacing the parts. Now it won't stop running and you can feel the fuel by-passing at the pressure regulator. When checking the pressure at the rail I get zero !! I used a tire pressure tester for this. And, like I said no pressure. This vehicle has around 170,000 miles on it.

I have a 2002 F150 5.4L (VIN-L) that has been sitting in the driveway since February. I have been a mechanic for 30 years for large commercial trucks, and my own truck has me stumped. I'm sure I've forgotten something but I'll try to list everything I have tried so far. It started with crank no start, no check engine light, checked for trouble codes got a trouble code for the CHT(cylinder head temperature) sensor.
- Replaced the CHT sensor. Cleared codes.
- Dash lights up fine, shows mileage, and anti-theft is not flashing while cranking.
- Fuel Pump does not seem make any sounds. Hit the tank with a hammer. Nothing.
- A little fuel comes out of the schrader valve on the fuel rail when I push on it. I have not checked it with a pressure gauge.
- Attempted to start with ether, nothing, so I'm assuming no spark.
- Fuel pump inertia switch isn't triggered.
- Checked several ground connections to the frame and checked ground connections in the PCM harness. All have less than 5 ohm resistance.
- Unplugged and plugged back in cam shaft sensor.
- Checked voltage on the TPS(throttle position sensor) I'm unsure about the results, if the TPS was bad wouldn't it just idle funny and/or stall?
Fuel Pump and PCM relays in the underhood fuse block appear to be good. All other fuses and relays appear to be good. I have been swapping the relays with one I think is good, although. Searched all over for additional relays, and found 3 inside the cab behind the passenger air-bag. Can't seem to find anything in the Haynes/Chilton manual that lists what they do. They are about half the size of the fuel pump relay.
Manually grounded the fuel pump relay, relay clicks but I don't hear a buzz from the fuel pump. Id like to run 12V to the fuel pump directly to see if that's my issue, but I'm not sure where to connect it without frying something important.
I bought the alldata.com DIY guide for my truck and it hasn't worked much. I have read extensively about others with similar problems and I just don't know what to do next. My main question here is, if the fuel pump is bad, would that stop the spark plugs from working? I'd rather not replace the fuel pump without being absolutely sure.

Having some problems with my truck.... First off I bought a 2002 excursion and drove it for one day. Then I was at the car wash cleaning up the truck. Then I saw the window fogging up so I turned the car off. Now it won't start.
I had previously installed a new stereo, but had some problems, so I ran the remote wire to the fuse box, because the wire in the harness wasn't getting power.. So after a little trouble shooting we found out that the fuel pump wasn't working or was bad.
We replaced it, now it has pressure but will not start, will start with starting fluid but will not crank on its own. someone told me it may be a bad PCM? and a dealer can only replace it... I don't have tons of cash, as i bought this truck on 8/30/12 and this happened the day after i bought it.
The previous owner has paid or the fuel pump replacing but I don't think its right on my part to have him pay more money as this may be a mess up on my part with hooking the radio up to the fuse box... we have tried the fuses,realys, crank sensors...

It turns over but just wont kick in. Battery good, fuel pump good, no check engine light. It did this a couple time this month, and finally started, not it wont start at all. Runs great otherwise without any issues. Just don't know where to look or what to look for. All fuses are good. Fuel pump safety is okay.

Let me start out by saying that I have exhausted every option that I have read on every thread that I could find on the internet regarding my son's 2002 7.3L not starting. What I have is no 12v power to the starter solenoid at the starter when I crank the key. What we have done so far, had the starter and both batteries tested, all good. Swapped out the starter motor fuse and the starter relay. Tried a new ignition switch and a new trans position sensor. Found major corrosion in the fusible link junction box on the drivers inner fender so we cut out the fusible links and put in a temporary jumper wire, still no crank. I have power to the dash, power on the power cable at the starter. I can jump the terminals on the starter and the starter engages. I found the shifter linkage bolts loose under the dash and tightened them up also. We have been struggling with this for 3 days, out in the lovely Michigan weather, since it couldn't have died in his parking spot in our heated shop, and I am completely frustrated. Are we overlooking something glaringly obvious?

Yesterday I drove my mom's 02 explorer to the gas station to fill it for her. After filling, I started it. It ran for several seconds and then died. It wouldn't start right away, so I let sit for a half hour, and then it started and I drove it 10 miles home. What is going on?

2002 F250 V10....
Ambient temp is 4-9 degrees
Step-son borrowed truck. I started it at 9 in the morn and moved it to a different parking spot on street. No problem starting.
Step-son came at 11 and took truck. It started no problem.
He drove it to work. At 5 p.m. would crank, but not start. A jump got it running.
On charger all night. Would not crank this morn. Would not crank even when jumped.
Are we looking at a bad battery or something else?

I have a 2002 F-250 with a 7.3.
I have been having a no crank, no start issue off and on for a while. batteries are new, cables are new, connections are clean, and starter has been rebuilt and checked. I bought a "starter relay" which i thought was the top solenoid in this picture. I also replaced the lower solenoid in the picture. The bottom solenoid was replaced with what im sure is the correct replacement. The upper I think is wrong. It started but then shut down and will not restart. The upper solenoid also was very hot after it shut down.
Long story short what is the upper solenoid for? Im assuming its not the starter solenoid. If so where is the Starter solenoid on a 2002 7.3?
