20 Most Recent 1997 Plymouth Voyager Questions & Answers


I am only guessing but it seems to me an ECU that can't remember anything is probably faulty.

Inside the ECU or ECM, the brain, the computer can be divided into sections like the circuit board of a radio or a laptop. There will be voltage regulators, an obd interface, a memory for the fault codes and a memory for recent history and a memory for the learned settings. There will be a memory for the preprogrammed settings and drivers for the ignition and injection system and an active computer making sense of the sensor information in order to make constant adjustments.

Just as with most things built on a single circuit board they rarely fail en masse. Usually what happens is just one of the on-board systems fail even though the result for practical purposes is the same as if the whole thing frazzled.
Usually When an ECU fails it is one of the essential functions which leaves no doubt it must be replaced but it isn't inconceivable that any section could fail - even one or more of the memory sections...

You did not identify the stereo but in common practice the pink wire (usually red) is for power and the yellow wire is for panel illumination.

Spray starting fluid or carb cleaner into the air intake to see if it really is a fuel problem. If it tries to start, like firing for a few seconds, it is probably not getting gas to the cylinders. Then you need to check the injector circuit. If fuel is getting up to the engine, then the pump is working, but maybe not good enough-check that by testing the fuel pressure. Hook up a fuel pressure gauge to the fuel rail, turn key to on, and you should see high pressure on the gauge, about 50 psi, but check for manufacturer specs for the correct pressure.

The injector circuit uses a fuse for the injectors, then it applies constant voltage to the injectors when the key is in on or run or start. See if you have voltage to the injectors with the key on. The injectors will pulse when the pcm momentarily grounds the injector circuit-it grounds each individual injector internally inside the computer for a split second. This causes the injector solenoid to energize and raises a pintle inside the injector so that fuel under pressure will spray out into the cylinder.

Have a look at this link and also look at the Video tab, There is nothing on your model but on others that will be very similar.

Rather then guessing as to what the problem is ,an just replacing parts ,your best bet would be to have a qualified repair shop diagnose it.

newer cars have switches for adjustment loosen mount screws there is a slot there move to one side and retighten. for cable on older cars loosen switch on side of transmission move and retighten, if cable is worn the shifter will show the same when in all gear. adjust cable mounts. also check motor and tranmission mounts.

Generally, if it crank good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse, if your missing everything, I'd check the cam and crank sensor signals. If only one system has a problem, we can check that one system. Could be other issues?

alternator fault, 12.6 should be min on fully charged battery 14.v min should be when the engine is running. when engine is turned off the battery should hang around 13.6 volts and drop steady to 12.6- 12.8 volts and stay there. faulty or damaged battery can damage the alternators regulator. or the bushes in the alternator. also check the earth from the alternator housing to the shell and battery and same with the positive wire from the alternator to the battery, battery should last 5 years but no more some don't even last 3 years, alternator that depends on how meany miles you do or not do as not meany miles the battery is always on charge and use from lights etc that put strain on the alternator. if you dont do meany miles put a larger battery on the vehicle, this will use less power to start the engine so the alternator can re charge on shorter journeys.

Check the transmission control module . You can find a Youtube video on where it is and how to remove it.

Inspect the fuel pump, fuel filter, & injectors... Give itt a smooth clean, check if everything is sits. If the problem still occurs, then you should visit or a call a Professional

I'd check those issues one at a time. Note the horn wiring diagram. I got the horn diagram because it is simple. The fuse is hot all the time, not only check the fuse, use a test light and check voltage at the horn fuse. The fuse and horn relay should be in power distribution center under the hood. If you pull relay and use jumper wire between terminals 30 and 87, with terminal 30 hot all the time, the horn should sound, If it does, problem is on control side of horn relay, left side, has to have voltage and ground. Top wire is voltage, bottom wire is ground. The wiring in steering column--clockspring--horn switch are all part of ground for the control side of relay. If the steering wheel has an airbag, have to disable and be careful with it when testing horn wiring circuits in the steering column.
Granted, your other problems maybe more involved? Check for applicable trouble codes

Could be a number of thing's , ignition system related , engine sensor's . The only way to know for sure would be to do some testing . I have seen crankshaft position sensors , cam sensors , coolant temp . sensors , mass air flow sensors, . It's just not that simple , what is wrong . U don't want to replace a bunch of parts that won't fix the problem . Your best bet would be to have it diagnosed at a qualified repair shop . It takes specialized tools to track down problems like this .
