the plugs will be fine
the gap for electronic ignition can be up to .55"
how you pulled the rubber boots from the old plugs determines if you damaged the plug leads as the leads will not stand being pulled on
you may need new plugs leads
next misfiring , missing is seldom plugs but dirty injectors or low fuel pressure
a point here--- plugs fitted to efi or ECM controlled engines will under normal operating conditions outlast the engine as they are not subject to the high current of the older engines

Somewhere between 90,000 mil;es and 120,000 miles you should do your timing belt. But first make sure you do not have a timg chain. If you have a timing chain, you never have to change it at all.

Have you performed a fuel pressure test? Does the vehicle even try to start?

This could be normal. You will need a constant power source at the radio to maintain clock and station memory

Check for proper fuel pressure, 44--50 psi. If your going to work on your own vehicles, you need a few basic test instruments, other wise your just spinning your wheels, hoping you get lucky and find the problem. You need a fuel pressure gage with the proper fittings to hook it up, if no Schrader valve. Also, you need an obd2 code reader, a basic tool. Some of them don't cost that much.

Check fuel pressure--visually check for spark at all the spark plugs--check for fuel injector pulse. Check valve timing.

Hi Andrew:
Many local tow truck operators know how the latches work and use a tool called a slim jim to trip the latch.

If you really want to give it a go yourself, I'd remove the interior panel on the drivers door so that I could see exactly how the mechanism worked. Using that knowledge, you'll have to practice using a skinny tool, wire, whatever works, to unlatch the drivers door.

Once you've got it figured out, apply the mirror image of that process to the passenger door.

When you achieve success, you will be well on the way to becoming a tow truck driver. (or a car thief)

Happy Happy!
