Help Please Jeep Cherokee won't start No Spark
Hi:
I've got a 1996 Jeep Cherokee. 4.0 with a standard transmission. I parked her a couple of nights ago and she wouldn't start up again. I checked for spark and got none. (Hopefully I'm doing that properly) I checked for and found no loose wires. I looked at the Distributor Cap and rotor. Both appear to be fine. They were both changed two weeks ago along with the new plugs and wires. My first instinct was the electronic control module. According to Jeep, this model does not have a module. Instead, it uses an onboard computer module. At almost $500, I'm not crazy about swapping that out unless I know its really at fault. For kicks, I put on a new coil. No change. I spoke to a mechanic who suggested a Transmission Sensor ( I think thats what he said...)Couldn't find reference to it in the Haynes manual I have. I'm about ready to have it pulled into the shop. Before I do, I thought I'd check to see if any of you folks had any ideas. Up till now (6.5 yearrs 185K miles) she has run flawlessly. I mentioned earlier that I had just changed the plugs, rotor, cap and wires. She ran well for a week or so. Then *poof* Any idea's would be appreciated. Thanks in advance. Tom |
Re: Help Please Jeep Cherokee won't start No Spark
You're describing a dead Crank Position Sensor - mounts on the top of
the bellhousing so the transmission reference the mech made is appropriate to the location. Well worth the $35-$40 and an hour worth of cussing the two hard to reach bolts since it's a common problem. All the manuals I've seen give a fairly simple test for a completely shot sensor using a VOM. Try unplugging it, clean the contacts, and plugging it back in. The plug is right up by the firewall just behind the fuel rail - look for a wire that runs down to the top of the bell housing.

Re: Help Please Jeep Cherokee won't start No Spark
He is referring to the top dead sensor switch on the bell housing, find it
unplug it then plug it back in it should start one time. When it is shut off it will not start again until its replaced.

Cool. THAT is what the mechanic guy said. I'll give it a try.

No luck. Sent it to a the shop. No luck there either. They say that
there is no power getting to this switch or to the onboard computer.

Re: Help Please Jeep Cherokee won't start No Spark
When my `89 Cherokee 4.0L won't start, I'll unplug the sensor, replug it and then I'm good to go for several months. I'm told 1) that it tends to get confused after oil changes and that 2) Jeep knew that it was a problem and issued a fix that didn't make it better.

Re: Help Please Jeep Cherokee won't start No Spark
When my `89 Cherokee 4.0L won't start, I'll unplug the sensor, replug it and then I'm good to go for several months. I'm told 1) that it tends to get confused after oil changes and that 2) Jeep knew that it was a problem and issued a fix that didn't make it better.

Re: Help Please Jeep Cherokee won't start No Spark
I remember some time ago, I had a similar problem on a 97 XJ. What happened
my kid left the interior light on and it drained the batter. The onboard computer lost in program. I had to start it like a old carburator vehicle, pumping the gas, and reving it up to keep it running for about 3 or 4 minutes untill the ROM downloaded the program back to the computer - which controls the fuel, etc. Jeep told me this. I esentially re-booted my car. Odd thing. I've completely drainded my battery in the past, and didn't have this happen. So try charing the battery way up, hop in, pump the gas a few times, hold the pedal down turn it over, if it sputters and tries, this may be the problem. Keep at it, mine stalled many times trying to keep it running. I ended up having to vary the pedal the entire time.

Re: Help Please Jeep Cherokee won't start No Spark
I remember some time ago, I had a similar problem on a 97 XJ. What happened
my kid left the interior light on and it drained the batter. The onboard computer lost in program. I had to start it like a old carburator vehicle, pumping the gas, and reving it up to keep it running for about 3 or 4 minutes untill the ROM downloaded the program back to the computer - which controls the fuel, etc. Jeep told me this. I esentially re-booted my car. Odd thing. I've completely drainded my battery in the past, and didn't have this happen. So try charing the battery way up, hop in, pump the gas a few times, hold the pedal down turn it over, if it sputters and tries, this may be the problem. Keep at it, mine stalled many times trying to keep it running. I ended up having to vary the pedal the entire time.

Its always the CPS when there is no spark. Just replace it. Even it it isnt

I changed my CPS and the prick stalled again 10 feet later. Mine was an almost dead ground strap from the engine head to the firewall cutting out the spark.
