Re: 88 xj Choking
I would next suggest taking a multi meter and check the resistance on
the TPS with the engine off. If you put the meter on ohms and then hand
move the throttle linkage, the meter reading should change nice and
smooth all the way to wide open. If it has a jump in there, it is
either dirty or worn out.
The plug and socket on the TPS can get corroded easily too, but that
usually gives stalls after a first start and high first idle rpm.

Re: 88 xj Choking
Well the fuel problems was a cracked fuel line. Its always some stupid
thing that breaks. But it still won't start sometimes. I will start one
time and not the next. It turns over fine but its like its not getting
gas or any spark. Do you have any suggestions.

I would be cleaning the connection on the CPS which is on the drivers
side bell housing just above the exhaust manifold.

Also check to see if your getting spark. Pull the primary off the distributor
and have someone hold it close to the block while the engine is cranked. Just
keep the primary closer to the block than your hands or your gonna get one
hell of a shock. I generally stick a sparkplug in the boot and ground it with
a jumper wire.
Not sure of the 88, but in later computers if the car doesn't get a crank
sensor signal in a couple of revs it cuts power to the coil.
That and all the fuses.
The other thing is to check the coil for any melty spots and the rotor for
a burnthrough. Sometimes the rotor burns through right were it sits over
the distributor shaft. Real pain in the *** to diagnose.
Oh Yea.. and one other thing.. run a heavy jumper cable between the
engine block and the frame. If you have a rotten engine ground strap
it will never start.
