in oct I bought a new car ..parked jeep for winter until I could replace the soft top
97 4cyl. 2.5 5 speed
when I parked it it ran
Jan tried to start it get it into garage dead battery & ended up a bad battery..gauges were working charged battery enough to get it to crank & gauges went out..I figure bad battery let it sit a while longer until weather breaks...now I got a new battery..still no gauges work no check engine..
cranks but wont start put in a new cps after reading some threads nothing??
Now when I put my key in ignition I should here the door open beeps but do not unless I push in a bit harder then I get the beep ..
could my ignition switch have gotten wet & bad causing the ecu not to come up?
or am I looking at the wrong areas...help please I am ready for camping & kayaking season
The only way to know is to get a code reader and see, not sure if they would work on a 1997 though? The starting could be fule related, did you use Stabilo or any other stabilizing agent before you put it away for the winter? Good luck.
Its easy to replace the ignition switch and its cheap. Chances are good that since 1997 that switch has been turned one too many times. There are plenty of threads showing how to do it. You will need a tamper proof #10 torx wrench that most auto parts stors carry. It took me about 15 -20 min to do mine.
Now if I remove f6 30 amp fuse under hood the fuel relay comes on & runs if I plug it back in it shuts off...also if key on & I unplug block 3 from ecu & plug in slowly all relays activate but still no gauges..could this be telling me ecu is still good just not comunicating do to a short??
Cranks great maybe still a bad battery?
Sp similar symptoms?
Did it fix it...Turning key should power ecu?
With key on I have power to fuse 9 10 11 in glove box?
Also will check volts at tps tomorow..
Digger I read another post that you made on this topic?
If I don't have the volts there ..that you are able to create those volts thru a cell phone charger??
If I find this problem could you help me with this?
The PCM supplies 5 volts on 2 or three harness wires to power the sensors
To see which ones for your year see FSM on line at Morris 4c4 knowledge base on their web site
Or download from jeepslimited.com after joining for free
If the PCM is not supplying the 5 volts you have three options
Replace PCM
Or
Try solder repair as shown on youtube link I posted
Or
Supply 5 volts with external voltage regulator like found in walmart items that plug into cigarette lighted and have USB ports as USB ports need 5 volts However make sure the amperage output is sufficient for the sensors you are powering
Clean your grounds. Especially the one on the side of the block. Bad grounds cause all sorts of strange problems. You can appear to have voltage but circuits will fail under load.
This all started when I cranked the engine on a battery charger...trying to exhaust all options before I try tapping into wires or getting a new pcm....
Have no power to coil either or must thus be done while cranking...
Relays all work..
This all started when I took first battery & charged it cranked it while still hooked to charger if that helps...trying everything before splicing into wires or opening up pcm...power into pcm but nothing seems to come out?
