Well lets hear the rest of the story, how did things eventually work out for you?

Been my experince that anything that moves and is packed with mud will soon fail. Most mud is mixed with sand. Pressure wash everything, check for mud traps, those places it gets into and doesn't want to wash out of, like the bottom of the rear quarter panels, inside the door bottoms etc...

I'd go down to Home Depot and buy a $3ß volt ohm meter, Test the CPS for ohms. my guess is it will read around 180 ohms or higher and you need a new CPS. If the ohms test out OK, scrub the connector pins with a good contact cleaner. Fish out the wires from the CPS to the connector and make...

My first guess was he had a connector making flaky contact someplace or a ground making flaky contact. Usually when the ballast resistor starts to go, it will starve the fuel pump of current (low fuel pressure) or even more common the motor will start off of the starter relay (fuel pump power...

The fuel pump relay routes current for the fuel pump through the ballast resistor, which actually lowers the voltage to the fuel pump. The current to the fuel pump is supposed to go through the ballast resistor after the engine is running. Though there is a second or two of overlap during...

I got to get some shuteye, I work swing shift, I'll be back in 5-6 hours. Good hunting.

The noise of the fuel pump priming the fuel rail when the key is turned to run is kind of subtle. I'd check for spark while cranking the engine over. If you have spark, look at the front of the starter relay, a hard to read molded in word will say BAL. Orange and bLack wire at the starter...

There are 3 or 4 relays in a block (row) about where the PDC goes in later years. The fuel pump relay supplies power to the ballast resistor after the motor starts (good CPS signal) and also primes the fuel rail (for a few seconds) when the key is turned to run on the way to start.. The...

I'm not getting exactly what your problem is? It will not shift automatically?

Supposed to be second from the front. But on my 88 it is in a different location, so it is likely there are some variables. What is your problem? It is likely I've seen it before. I've been screwing around with XJ's since 1987 . I've looked at two different drawings of the relay layout, one...

The IAC is the idle air controller. With the throttle plate closed (foot off the gas pedal) it is the only way for the motor to get air at idle (foot off the gas pedal). They get sticky and/or the charging system gets weak and the IAC acts up. When they stick closed at idle or when releasing...

Which engine? If it is the 4.0 the IAC is worth a look. They usually screw up worse when cold. Two reason for intermittent problems with the IAC, on eis something in the charging system isn't right, battery, alternator, grounds. The IAC sees to need every bit if voltage it can get to work...

I'm pretty sure they are M 12 bolts, but hardened, 10.9 equal to a SAE 8. I remember using a regular socket, half inch drive to get them out, nothing exotic. Getting the hub off is a whole other can of worms. I buy three M12 x 100MM bolts, screw them in there and use a big hammer on the bolt...

Here is where I get my steering boxes, Lares Corporation. Tire balance usually hits around 60 MPH/110 KPM. Bad U-joint is also a possibility, especially the front axle U-joints.

I read somewhere that the rear O2 sensor makes sure there is enough extra oxygen for the newer type catalysts to function properly. It has to have some sort of trim affect on the fuel to air ratio. It may be mor eimportant than people think. I've seen the wires for the rear O2 sensor short on...

The book says the dark green should be near battery voltage with the engine running and the ASD relay energized, voltage into the field windings. You can test this at the green wire disconnected from the alternator. That thing you are looking at is doubtful to be an external regulator, more...

Found this, may be helpful :).

I'd check the wheel brake cylinder, you can usually tell by the smell if it is brake fluid or differential oil. Pretty common for the rear brake cylinders to leak in XJ's, likely the same on the GC. If the GC has rear discs disregard ;). I've had some really old XJ's that had a tiny seep at...

The green wire is supposed to be power in to the field winding, the orange and green wire is to the regulator (in the PCM/computer). It is actually regulated on the ground side in most newer vehicles. Which sounds odd but the electricity doesn't know the difference :). The output of the...

I've tried all sorts of stuff over the years, I tend to shy away from a torch. Mostly now I grind it down until it is almost through, Notch it, use a long pointy punch and a BFH to crack it. If the punch nicks the race seat, no big deal, nothing a little sanding won't cure. A set of those...
