That's what I figured.

I didn't replace either of them. I've had the car for about a month, and it
ran fine until this. I figure it has to be something electrical, though.
It was running fine when I parked it. Then, when I went to leave, it
wouldn't start.

After I replaced the TPS, I unhooked the battery to reset the codes. Since
then, I haven't had any codes except 12 and 55.

Or worse, fill a cylinder with fuel then fold a connecting rod when you
start it up afterward.

Naw, I just suggested it 'cause I get my jollies from making people do
pointless stuff.

Dan's suggestions have caused me to invest SO much additional work on
my own cars that I now take my car to the dealer for even the simplest
things, like refilling the washer fluid bottle, checking oil level and
tire air pressure.

NOT!!!! ;-)

Well, I get MY jollies from watching people refuse to take good advice,
and then whine that the car is still broken :-p

Ooohboy. Chilton books will get you nowhere in a big hurry. You need a
factory book. They're not hard or expensive to get.

Good way to fry a fuel injector,,, AND ONCE AGAIN HE RUNS HIS MOUTH< ON
PAGE 15 OF THE CHRYSLER PRINTED DRIVABILTY BOOK IT STATES T O GROUND THE
WIRE AND CONNECT A JUMPER WIRE TO THE OTHER END

instead of helping the OP to understand that the only
way he's going to get his car working again is through systematic and
proper diagnosis?
IS THAT WHAT YOU CALL WHAT YOU ARE DOING, the book is right, but daniel
wants to rewrite it

You dont have a fault for distributor reference signal (No distributor
reference signal detected during cranking) You dont have a fault for
Injector peak current (caused by high resistance in the control circuit)
which is also the PCM test, You dont have a fault for injector control
circuit ( engine controller does not sense injector switching on and off
when a control is switched) so all those tests i would assumed pass, the
only thing it does not test is if the pintel is opening, you would need a
lab scope for that. but as our friend Dan C states, they did not have many
problems with that injector, but then again the car is 14 yrs old, once
again, if you supply fuel(starter fluid) and the engine runs and all other
test passed especially the TPS sensor ( cause if will shut off fuel) and the
speed sensor cause it will also cause a no start if bad, then i would have
to say the injector is faulty, assuming all others passed, this is the last
post i will make to this, i dont get into these games with people like
daniel. there was also a recall out on the 2.5/2.2 for replacement of the
injector, im not sure what yr it was , give me the serial number via my e
mail address and i will check for you. it may have been 1988 im not sure

....and he doesn't have a prayer of doing any meaningful system diagnosis
by means of flash codes obtained by watching the "Check Engine" light
blink.
