The car doesn't start. its flashing the HOLD led.

why not ask maker,?

Get under the dash or where the unit is located.
You will see 8 or 9 dip switches on the unit with an LED beside them.
Turn switch 1 and 8 on.
Press and release the brake. (LED will flash)
Press and hold start button on remote. (LED will flash and parklights will flash once.
Turn switch 1 and 8 to off.
Press and release the brake (LED will flash once)
In future would be a good idea to supply vehicle details etc as can sometimes be a known condition , that saves time looking it up , good luck

High voltage at the coil means nothing. Hook it to a plug and hook a timing light to that cylinder. If during cranking the timing doesn't flash, you still have ignition problems. Note, it must flash during cranking. Hold trig down.

OK got your message on the other post (About the van) I am assuming that your Voyager is equipped with Automatic Climate Control. Follow the instructions below and you will get a better idea of what is wrong with your system.

Calibration/Diagnostics
1. To enter calibration/diagnostics test, set parking brake. Start and warm engine to normal operating temperature. With engine idling, turn blower switch to high. Turn mode switch to panel. Open all outlets. Move temperature to full cold.
2. Press and hold rear wash and rear wiper buttons simultaneously for 5 seconds (Until ALL LEDs illuminate). All LEDs should illuminate for 5 seconds. Rear wiper and intermittent rear wiper button LEDs will flash alternately during calibration/diagnostics test.
3. After approximately 60 seconds, if only the rear wiper button LED is flashing, calibration is successful and the system is okay. If rear wiper and intermittent rear wiper button LEDs are flashing, Diagnostic Trouble Codes (DTCs) are present. (See "Reading Diagnostic Codes" below)
4. To exit calibration/diagnostics test at any time, press the rear window defogger button, rear wiper button, or cycle the ignition off and then on. Test will automatically terminate 15 minutes after calibration/diagnostics is entered.

Reading Diagnostic Codes
1. Perform calibration/diagnostics test. If a DTC is present after calibration/diagnostics test has been performed, system will flash rear wiper and intermittent rear wiper button LEDs in sequence. Rear wiper represents code level, and intermittent rear wiper button LED represents code value.
2. Each time the rear wash button is depressed, rear wiper button LED wil cycle to the next code level in numeric sequence. After code level 5 is reached, rear wiper button LED will cycle back to code level 1. See table below.

One of the fusible links are burnt or broken. Check leads from positive battery cable and ground leads in engine compartment

I can answer the FIRST question.

A. Car is off.
B. With car off, hold down BOTH trip buttons that are to the right of the tach.
C. Start car while STILL holding the buttons down.
D. Hold buttons down until they stop blinking THEN RELEASE THEM BOTH.

Done!

Note: That Maint.Req'd light is nothing more than a "timer". It doesn't mean anything. It is supposed to go off to remind you to change oil, etc but doesn't actually measure anything.

Unlock vehicle. Enter vehicle. Close driver's door. Switch ignition ON and OFF. Remove ignition key. Press and hold unlock button. Press lock button briefly 3 times within 10 seconds keeping unlock button depressed. Release unlock button. Some models: LED flashes slowly for 10 seconds. Some models: Central locking system locks and unlocks rapidly to indicate correct programming. Repeat above procedure if central locking system does not work and LED does not flash or LED flashes continuously.

The blinking lights in the rear wiper rear defrost area can be reset by holding 2 buttons of the 3 on the left hand side. The top and bottom buttons. Turn the key on and hold them for about 10 sec and they should start flashing differently. Just let it do this. After they start flashing different. It will take 5 to 10 mins. Then one or more will quit flashing all together. If they don't after about 20 min reset them again it can take about 5 trys sometimes before they all go out.

it is flashing because you have had power loss of some kind. so you will have to recalibrate the unit. start by warming the van up for about 5 minutes. leave it running, then press and hold the bottom left and bottom right buttons together till they start to flash.
(they will flash different then they are now)

once they flash let go of the buttons and wait untill they stop flashing.

then turn van off. wait 5 seconds and then start van again. Now press and hold the bottom left and top left buttons together untill it flashes.

once the flashing stops then press top left button and you should be complete. :)

To Calibrate , start and warm engine to normal operating temp. with engine idling turn blower switch to high, turn mode switch to panel, open all outlets, move temp lever to full cold.
press and hold rear wash and rear wiper buttons simultaneously for 5 seconds (untill all leds illuminate.) all leds should light up for 5 seconds, rear wiper and intermittent rear wiper button leds will flash alternatly during calibration... after 60 seconds if only rear wiper button led is flashing, cal. is complete
