Title: Starting ?
Post by: Plum on August 25, 2006, 07:26:05 PM

Heres a question for you all . . . . . .

Me 91 xj automatic has occasionally been temperamental . . . . . . .

(a) engins off an ive mooved the gear stick from park an back again (wont start)

(b) stopped engin whilst stil in gear"reverse or drive"  when goin to restart 10 mins or even 24hrs (wont start)

some times will start after about half an hour after first trying ( very strange indeed. . . . .

other times have to rock it in park . . . then pop into neutral move forward then hey presto . . . . . . .

on occasion all i need to do "if parked on a slight slope" is disengage the handbrake . . . . then fire away  . . . . . .

to be honest im just bemused . . . . . . .any advice welcome  .  . . . . . .

cheers Plum . . . . . . . .i know before you say it im a dipstick  :lol:

And its the 4.2 carb?

When you say it wont start, do you mean it wont even turn over? It could be the neutral position switch either faulty or out of adjustment.

On the XJ that I had from Tank you sometimes had to wrestle with the shifter to get her to start.

Had a similar problem on my old Range Rover. It was the Park Inhibitor switch. I think thats the same thing as Mark is talking about in Landy Talk

Dont even know what "NSS switch" is Daggie :?  :?  :?

Post by: daggie on August 27, 2006, 11:42:11 AM

neutral saftey switch, on the side of the gearbox  :wink:
it will only start in park, hence if you have to wiggle the selector = dodgy nss

that is a 4.0 fuel injected engine by the way

It sure doesn't look like a 258 carry over.

Title:
Post by: chrisjones on August 27, 2006, 01:21:36 PM

Yup.  That be a 4.0 not a 4.2

Title:
Post by: Mike Pavelin on August 27, 2006, 03:04:23 PM

Yup, thought it would be, it's a 4.0 High Output.
The problem is likeley to be with the neutral saftey switch which is incorporated in the switch pack on the side of the transmission.

Post by: Mr.Stu on August 27, 2006, 09:13:09 PM

You should be able to start it in N as well as P, but not R, D, 3, or 1-2.

Almost certainly the NSS.

"c" How can u tell the diff between 4.0l an 4.2l please ? ? ?

Post by: Manda on August 28, 2006, 11:53:05 AM

As far as I know the 4.2's are carbs, so they have a big round air filter on the top. (Unless they've had an injection system added). They also tend to be in older models e.g. CJ's, early YJ's etc.

My Log book tells me Mines a 2.5. I checked it with Jeep and it was built as a 4.0! I tried telling them and they still didn't change it. Just sent it back with 2.5 on it again.

EE

Post by: Manda on August 28, 2006, 12:02:04 PM

Ed - my log book says it's a 2.5, as far as I can remember this refers to the model not the engine size. Like referring to YJ's as hard tops and TJ's as soft tops.

Plum - the carry over bit Mark was referring to is when Chrysler 'used up' older engines in newer models, 258 the cylinder capacity of a 4.2l in cubic inches. They did this with some YJ's, using a 'CJ engine' in the new models.

Post by: Anonymous on August 28, 2006, 07:25:02 PM

Macs Mums log book calls it a 2.5 also but has 3960 as the engine size

Cheers Manda . . . . . .

my motor seems to be a bit of a strange one as even the local steeler cannot come up with anything as the chassis no is 3 digits short of the norm an doesent exist on the world jeep data base (apparently) . . . . .. .

therefore am gonna get in touch with JEEP an see if they can shed some light . . . . . .. once againe cheers . . . . .

If it hasn't got a 14 digit VIN, it might be a Chinese one. They're made by Bejing Jeep, and DaimlerChrysler don't hold any information on them.
