1998 ZJ stalls with no dash lights, radio, windows
I have a 1998 YJ (amongst other jeeps) this one I loaned to my dad while his ZJ was in the shop for new tires. He said that he started it cracked all four windows, then the radio and dash lights went out, and it died while rolling down the road. Tried to restart and it cranks but not fire. NONE of the dash lights work, nor the radio, nor the windows! My local shop wont touch it, for some reason? They thought it was the ignition lock cylinder was worn out. Does that sound right? I already owe these local jackwagons 120.00 for them to tell me they will not work on it..AT ALL!
Hard to tell over the web but things that will kill a ZJ are crank position sensor, cam shaft position sensor, bad computer, check for blown fuses in the PDC under the hood, and inside the passenger door kick panel. I wouldn't take it back to those guys. Is it a 4.0 or 5.2?
Checked fuses...all good! Would crank sensor or cam shaft sensor kill the accessories? (dash lights, radio, window operation) The crank position sensor on the bell housing? And the Cam Shaft Position Sensor under the distributor plate? EEEK @ bad computer! This could be bad...
Why would the jeep crank over like there is no tomorrow if it had a bad battery cable or connection? I think that a bad battery/connection would limit the ability for the starter to engage!? Turns over great, starter kicks in great! Turns for 10 seconds, sputters a little, then continues to crank over with no fire. I turn the key off, then on. Again no dash light, radio, or power windows, BUT it cranks right over with no problems for about 10 to 15 seconds, sputters a little like it wants to start, but nothing! Checked all fuses they're good, replaced crank sensor and cam sensor. Still same scenario.
How about the security cut off? Do you think it may be shutting it down? When My battery got really low the security triggered and it would crank and run really rough but I had to hold the pedal down to keep it going. If I let off it would shut down.
I read somewhere on here that the crank sensor wiring controls the dash/gauges and the fuel pump as well
Engine speed and crankshaft position are provided through the crankshaft position sensor. The sensor generates pulses that are the input sent to the powertrain control module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing.
the cranksensor can short across the sensor supply voltage from the PCM and cause reverse biasing of the circuits inside the PCM, which may cause failure of gauges and fuel pump.
Humor us and re-check the fuses under the hood. Let's get that out of the way and settled, ok ? Use an ohmmeter on the ( 10 amp? ASD fuse) It turns over...right? That's the first place I'd look. Take that fuse out and check it.
Next would be to swap the horn relay with the asd relay ( under the hood)....assuming your horn works.
ASD relay is good! Come to find out ...my battery had a shorted plate in it...NEVER have I heard of that! My neighbor walks over and say "whatcha doin?" I said checking this and that, and that and this, yadda yadda! I showed him the problems I was having. Battery TESTED GOOD, sitting AND UNDER LOAD! BUT when I tried to roll the power windows down, the battery guage DUMPED, the truck stumbled and DIED! He says "junk battery"! I pulled my tester out and it said 12.8, started it up tester read 14.3! While idleing I tried again to roll the window down. Guage DUMPED, idle stumbled and DIED AGAIN! This time when I rolled the key back on, nothing! No dash lights, no radio , and no windows! I took the battery out, took it to O'Reilly's had it checked out. They said this is a GOOD battery! Went back home put it back in, started right up! Pushed the rear window button down, guage dumped, truck died! I just bought a new battery, put it in last night and no problems so far! We'll see...
