Ford - Explorer :: 1997 4.0 SOHC Would Not Turn Over When Trying To Start
Apr 23, 2017
Drove it yesterday no problems. got in this morning tried to start and would not turn over. thought it was a dead battery. Ran jumper cables to my wifes car waited for a while tried again. nothing. bought a new battery put it in. Nothing. I did notice when turning the key the dash lights come on then half a second they go out. interior lights, and 12v outlet work but no headlights. Any issue other than the obvious corroded terminals or loose terminal wires?

I just bought a 2000 ford explorer which didn't start... I put a new fuel filter, spark plugs and air filter in it...still not starting ...gonna do a a compression test tomm. and see if it the timing chains or tensioners... Sounds like its misfiring actually, it doesn't start with starting fluid sprayed in it....where is the ignition pickup located on these things? I still need to put a new ignition coil and wires on it. plugs were in horrendous shape and i thought that was the problem.

4.0 SOHC cranks once no start, then starts on second crank. 104K miles and used to idle very smooth, now mildly rough and sometimes upon stopping the rpms will dip down to almost stalling but not every time. Also just had the fuel pump replaced.
Also... Seafoam? Is this really as good as it sounds, I mean it can be used on anything, except cereal!

I have tried playing with screw that controls throttle plate it does work at first allowing to reach 1200 rpm at idle however after stopping car and starting again it does go down to ~600rpm again like computer adjusts it back to desired level. There's also **** on Idle valve however turning it does nothing.
Is there way to reprogram computer to make 1200 a desired RPM?
Like try this yourself reach about 1200 rpm and then hold your leg still not looking at the rpm your once you hold it for a while it goes down to normal rpm, only way to hold constant 1200 RPM is to play with gas pedal.
I want to raise RPM to avoid misfire.

I'm having a little bit of trouble finding the cause of a minor problem on my 06 Explorer with the 4.0 V6 engine. When the engine is running cold at idle, it runs a bit rough and idle speed is high as well. When fully warm, the engine runs and idles fine. I hooked up a scan tool and there are no pending or stored codes. The live data looks ok except the long term fuel trim which is at about +10% on both banks during idle, indicating a lean condition. Short term fuel is right around zero. The MAF and TPS values seem to respond fine when applying steady throttle.
So I assume there must be a fairly small vacuum leak somewhere that the PCM is able to compensate for since the long term is only at 10. I didn't see anything obviously wrong, the vacuum lines look fine along the passenger side near the firewall. I sprayed a bit of throttle cleaner along the hoses, intake manifold and gasket area, but could not spot any vacuum leaks. Any other common areas to check for leaks on the 4.0 V6? Perhaps there is something I am missing?

Replacing the timing chains and tensioners on an SOHC Explorer, only to have the tensioners fail again after only a few thousand miles? I'm a pretty experienced back yard mechanic and have rebuilt several engines over the years with great results, but this one has me stumped. The only part of the instructions I did not do was to remove the valve springs, but everything was lined up as it should have been using the special tools required to set the timing. I really like the truck, but don't know if it's worth fixing if this is just going to happen again.

I have a 2003 Eddie Bauer explorer with the 4.0L SOHC . I have a coolant leak from the passenger side that is not a water pump issue.
When removing the timing chain cover with the engine in the car, do I need to remove any accessories ( power steering , alternator etc. ) or their brackets?

On my 97 X SOHC, I have a temp gauge that is rather erratic. It reads high even with the engine off and cold and rises when the engine is running to the point the "Check gauges" light illuminates. Then bounces to normal then back near red line. This cycle continues.
To evaluate this, I bought a scan tool and the ECT reads as expected, around ambient to start, gradual climb till the thermostat opens, then hovers there while the radiator does its thing. Heater works as expected. So I'm fairly confident that my X doesn't have a cooling issue.
What my questions are: Can I disconnect the temp sender so I'm not watching the gauge bounce around and then the Check Gauges light is available for other issues that arise?
Does the check gauge light also send a signal back to the PCM?
Can I do any damage to the truck or will the PCM throttle the power back and flash the Check Engine light if a real cooling issue materializes?

Have a 97 Ford explorer. Over 270,000 miles on it. Recently had Crank sensor, Crank case vent tube, plugs wires replaced along with intake manifold gaskets. Also had fuel injectors cleaned out. Now i cant get it to turn over. Went to store, truck started fine, came out and click. Thought it might be the battery even though its also brand new but no, had the starter checked, it is also good. Put test light on all electrical having to do with starter and found all hot wires and good grounds. Finally bypassed the solenoid for starter and still nothing but a click. I also checked NSS to see if that might be it but after putting it in reverse, the reverse lights came on, and even jiggled shifter in park and neutral to see if that might work but still just a click. Not sure where to go from here short of buying all new parts but doesn't make much sense to do that if they all appear to be working properly. Don't have a volt meter to check voltage.

1997 Ford Explorer 4.0L the engine just died while idling. The engine will not turn over at all. Battery and cables are good. Able to get engine to turn over with screw driver on starter relay but still won’t start. Checked spark when bypassing relay with screw driver and spark is Ok.

I drove a '97 with the 5.0 and AWD. I noticed that when I turned around in the neighborhood, the steering started to feel a little heavy during a U-turn. I was pretty close to full steering input to the left, but not quite at the lock. Also, it seemed like the tires might be scrubbing the pavement a little bit. No real binding or hopping, just that feel you get when you have the transfer case locked in your old-school 4X4 and make sharps turns. Is this typical for the AWD?

1997 Limited SOHC auto.
I just replaced the transmission with a known good one from my XLT but the reverse doesn't work now and there is a loud banging coming from the front when I turn left or right.
It feels like the tyres are slipping on the road, like axle wind up. This happens in auto and 4wd high. What the banging is?

My 2002 F150 Screw has been giving me issues when trying to start it for the last month. Sometimes it will start sometimes it won't. When I turn the ignition on the gauges all seem normal, the theft light turns solid then goes out, but engine will turn over but not start. Sometimes it will start if I leave the ignition on for 20 seconds then pull the key and try again. (this doesn't always work). I have disconnected the battery for about 2 minutes this usually works but not always.
Sometimes it will start first time with no issues. Once the the engine fires it runs fine. Another symptom is when I shut the engine off, pull the key and open the door, the chime telling me that the key is still in the ignition sounds. (but the key is in my hand)
I put a new battery in yesterday to rule that out and because the old one seemed to be getting weak. (starting issues didn't go away). I don't want to put 300+ into a fuel pump without being sure that's the problem.

So I've been away a long time. My sister recently bought a 1997 Ford Explorer with the V8. When she tries to turn on the cruise she says it throws the transmission in to neutral and then locks the gas pedal...

Ok so I have a 1997 Ford Explorer with the 4.0 SOHC .. The girl that owns it went out and started it to warm up and went back in the house , when she came back out it had died and wouldn't start .. I hauled to our shop and started diagnosing it .
It has spark
has fuel
Timing is good
Fuel pressure regulator is good
Crank sensor is good
About 62 PSI fuel pressure
No CEL
Seems to be getting WAY too much fuel and fouling plugs !
Replaced ECM ...same thing .
Used NOID light on injector wire and I have never seen one get so bright !

I have a 1997 Ford Explorer. Starting about 4 months ago I have had intermittent problems with it not wanting to start.When you turn the key the radio and dome lights etc. come on but it is dead silence from the motor.First time it happened we ended up replacing the starter solenoid. Next time we discovered that if you "jump" the 2 posts on the solenoid (using well insulated rubber handled pliers) while turning the ignition it will start every time.Took it to a local, reputable mechanic - he is baffled. They looked at every connection and wire they could think of.It is not the battery or solenoid, as best we can tell. It does not do it all the time. It will ocur, then it will start fine for 2 weeks then happen 3 times in a row, then not happenf for say another week or two.

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 a '97 Explorer XLT with a 5.0L V8. Recently, I've developed a problem, in which it doesn't always start. Sometimes, when I turn the key, there is a very loud click (as if the solenoid is engaging), but there is no start. The battery is NEW, and confirmed good, and the terminal connections are tight. I have also replaced the solenoid, but the issue remains.
If I turn on the headlights, before trying to start it, the lights DO NOT dim when the key is turned...indicating NO draw, on the electrical system. I can try it several days a week, unsuccessfully. And then, one day, I can turn the key and it will start as if there was never a problem to begin with.
I have lost confidence in my favorite vehicle, as I am afraid to drive it if/when it does start, for fear of being stranded. I am thinking it may just have a bad armature, or windings in the starter, but if that doesn't correct it, I can't return the starter (as it is an electrical component).
