Must take out and reinsert batteries each time I try to use clicker. Sometimes have to repeat for 10 minutes to turn on.

Replace the fuel injectors.

Not certain this will work on your truck, but many will reset by turning key to "on" but don't try to start, leave on for about 15 minutes, turn off, then try to start.

hi cbonge,

A battery reset procedure should bring your Ti 84 Plus back to life.

Make sure the batteries are in correctly? The batteries alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. I know if it happen to me that anybody could make the same mistake. And of course, the calculator will never come on if the batteries aren't in correctly.

The process below should reset your calculator.

Please be prepared to re-install the calculator's OS if you run through this process.

1). Pressing the [2nd] key followed by pressing and releasing the [Up Arrow] key. This adjust the contrast in case the contrast was to low. Keep repeating if necessary for about 10 seconds and, then go to the next step. If calculator comes on and responds to key functions your done.

2). Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR],
reinsert the AAA battery and then turn the calculator on. The calculator should display the
message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message. If calculator starts responding to key functions your done.

3). Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display
"Waiting...Please install calculator software now". Follow the instructions for the
TI-83 family or TI-84 Plus family to reinstall the calculator operating system.

4). Steps to re-installing the operating system:
~Connect the TI Connectivity cable between the PC and the calculator.
~Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
~Follow the on-screen directions to reinstall the calculator's OS.

5). Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

6). If the above process did not work. Try re-doing the procedure and, extend the time in step 4, by 5 minutes to 10 minutes before you put all the batteries back in the calculator. These calculators can be a little stubborn at times so, keep trying and follow the procedures.

hi bckyshldn,

Did you remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. In the procedure that I give, you hold [DEL] and, re-insert 1 battery. I'm going to go ahead and, restate my instructions for a ti 83 Plus that won't turn on.

Make sure the batteries are in correctly? The batteries alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. I know if it happen to me anybody could make the same mistake. and of course the calculator will never come on if the batteries aren't in correctly.

The process below should reset your calculator.

Please be prepared to re-install the calculator's OS if you run through this process.

Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.

1. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR],
   reinsert the AAA battery and then turn the calculator on. The calculator should display the
   message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message. If calculator did not display the message try pressing and releasing the [2nd] key followed by pressing and releasing the up arrow for one second. goto step 2.
   
2. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display
   "Waiting...Please install calculator software now". Follow the instructions for the
   TI-83 family or TI-84 Plus family to reinstall the calculator operating system. If the calculator did not turn on connect the calculator to the computer and open Ti Connect. Next, open Device Explorer. Is the calculator asking to be installed? goto step 3.
   
3. Steps to re-installing the operating system:
   

   ~Connect the TI Connectivity cable between the PC and the calculator.
   ~Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
   ~Follow the on-screen directions to reinstall the calculator's OS. When or, if the calculator install the fresh OS goto step 4.
   
   
   

4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.
   
   
   

If the above process did not work. Try re-doing the procedure and, extend the time in step 4 by 5 minutes to 10 minutes before you put all the batteries back in the calculator.

Now just in case this calculator wasn't posted correctly. Here's my instructions for a Ti 83 that won't turn on. This is not the same procedure that the Ti 83 Plus has.

1. Try a new set of AAA batteries.
   
2. Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.

   AAA battery and then turn the calculator on.
   

4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. And of course if the calculator does not turn on, I re-do the procedure and, increase the amount of time by 5 minutes to ten minutes that all the batteries are removed.

Are you sure the batteries are in correctly? They alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. You tried adjusting the contrast. Just try adjusting upwards. Sometimes it takes a little for The Ti 85 to come on or adjust right. The Ti85 is an old calculator and, may not work any more. I had my Ti89 for almost 20 years so, they are pretty reliable. If nothing has worked take out all the batteries including the small one in the back. Texas Instruments say's " leave them out for 5 to 10 minutes." I had to leave mine out for over a 1/2 day to get it to work.

Here is the battery reset procedure for the Ti 85.

Try a new set of AAA batteries.

1. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing
   the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
   
2. Remove one of the AAA batteries. Press and hold the [ON] key for 20 seconds. Reinsert the
   AAA battery and then turn the calculator on.
   

3. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute
   

4. period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.
   

Just keep trying. Sometimes they can be a pain.

this is a pass key problem, try this.

PASS LOCK RESET GM CARS 1999 UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key

try this: turn key on, crank starter for 1 second, leave key on for 10 minutes. after 10 min. shut key off and repeat 3 times. (on second try, crank a sec. or so longer, the reprogram may take off right away. if not, repeat make sure battery is strong, key could be on for 1/2 hr. sometimes engaging emergency brake before key is turned on prevent daytime running lites to come on to save battery power (if equipped). been through it, thought i'd mention it
