#52 of 188 Electrical Problems at Start-up by rangerboy1 Oct 01, 2007 (1:36 pm)
I have a '97 ranger, 4 banger. I was recently having problems with my altenator shooting the right voltage to my battery, as indicated by a light on my dash and verified with my meter. I replaced the altenator and the battery as this has been a problem I let go long enough to fry the battery as well. The last few times I drove it before replacing these, however, a new quandry appeared that still has me perplexed. That is, when I turn the key the entire electrical system goes completely dead and I get nothing the next time I turn the key. I can disconnect the battery, though, for a few minutes and connect it and get power back to the instruments but will go dead again once the key is turned. With the entire electrical system being affected, I have suspected problems with the PCM or its relay. Am I going down the right path, or is there something I am overlooking? Thanks for your help!

#53 of 188 90 ranger starting problems by jason200x Nov 07, 2007 (12:02 pm)
I have a 90 ranger 4x4 xtended cab with 4.0liter and automatic transmission. I have a problem starting it in the morning. It takes least 2 times turning it over for a few seconds before it will start, and then runs perfectly. It is beginning to get worse, taking longer to start. The temperature doesn't seem to matter. Once i have started it for the day, it starts fine afterward as long as it doesn't sit for more than a few hours. I put the engine in this truck from my brothers wrecked 92 explorer, which also had this starting problem. The only electronics that remained from the explorer are those bolted directly to the engine, so I am assuming one of these sensors may be the culprit. Any suggestions would be greatly appreciated.

Replying to: jason200x (Nov 07, 2007 12:02 pm) A couple of possibilities: - A weak fuel pump. Any motor is harder to start when cold, and you may not be getting enough pressure to the injectors. The fuel rail will have a schrader connection, where you can attach a fuel pressure guage. Sorry, I don't know the correct pressures you should look for.   - There probably are two temperature sensors on the motor. (Although, with a motor transplant, who knows what is still hooked up....) One sensor drives the temp guage. The other sensor tells the computer that it is a 'cold start' and changes the gas delivery - basically I think this means it delivers more gas by keeping the injectors open for a longer time. If this sensor is bad, the computer does not know it is a cold start and uses the 'regular' gas delivery, which mean it is tough to start when cold. But warmed up, the 'regular' gas delivery is fine and the motor starts fine.   I don't know exactly where these temp sensor are at, but my guess would be on or near the thermostat housing. Another guess would be that the sensor to the computer will have a pair of wires, black and yellow, twisted together. Replacing this sensor might be worth a try.

The clamp on the post had been replaced bythe previous owner and the wiring coming from it was not making a good connection. I clened the wiring, put a closed-ended crimp connection on each wire, and reconnected to post clamp. I have had no problems since.
#56 of 188 Ranger hard start has become ranger won't quite run... by amazonafaun Nov 27, 2007 (9:54 am)
My beloved, super-dependable 1998 Ranger 4.0L has suddenly become very hard to start and will only run with pressure on the accelerator. It has had a couple of hard start moments over the last few months (temperature independent), but nothing consistent enough to be a clear problem. However, yesterday morning (it was below freezing) it would turn over, but not start, unless I gave it quite a bit of gas, and once started, it would only remain running with pressure on the accelerator.   I should also admit that I test drove a chevy the night before, and my truck may simply be punishing me- however any insights as to how to make my truck happy again would be much appreciated. My previous ranger had serious fuel pump issues (went through three), so I am wondering if that could be happening to this truck as well.   Thanks!

Replying to: amazonafaun (Nov 27, 2007 9:54 am) To the previous post with a 1998 Ranger 4.0L, that sounds like an Idle Air Control Valve (IAC). I had that problem and was able to temporally fix it by removing it, blowing high pressure air into it to clean it, and putting it back (then driving to the store to get a new one). If it is the IAC, it will start and run fine if you depress the gas, but if you totally let off the gas it stalls out.   Hope that helped
#58 of 188 Ranger ignition problem. by cskoda Nov 30, 2007 (12:32 pm)
I have a 1996 ranger with six cylinder. When I turn the key I get nothing. No radio no dash no blower motor and engine will not turn over. I do have headlights and emergency flashers. The car has sat for months and the battery died. I changed the ignition switch, battery, solenoid cleaned all battery contacts body ground contacts and starter contact and still nothing. I checked all fuses at the dash location and at the power distribution box under the hood and everything is ok. . Turn the key and it's like it's dead. Anyone that can help I would appreciate it. I'm trying to get it running for a kid in the neighborhood.
#59 of 188 problem starting by revmred Dec 18, 2007 (2:25 pm)
I have a problem starting my ranger, I replaced the battery after a severe cold snap thinking this was the problem, yet it continues, I thought maybe cables you can boost it off and it wills tart. I boosted it off today drove it about 3 miles. Killed it and tried to restart, it was like there was no battery at all. HELP!! I took cables off and am going to replace them, but should I have started somewhere else, or should I try something else first?

Replying to: revmred (Dec 18, 2007 2:25 pm) Did you have your alternator checked out? That may be your problem. Replies to this message: fotd1 (Dec 26, 2007 11:48 am)

Replying to: obyone (Dec 20, 2007 2:35 am) The original symptoms did not state whether the engine turned over, but did not start. There are a couple of known issues with some years of Ford Rangers that affect starting. The crankshaft position sensor goes bad; the engine turns over, but spark and injector firing are intermittent-if at all. Longer shot could be a problem with the wiring harness (cracked insulation). If the engine doesn't crank (assuming good battery) check interlock switch on clutch/auto trans.   fotd1
