Maybe -- a failed fuel pump--that can be tested in several waysClogged gas filter--only if it has been in the car for 8 yearsFuel Pressure Regulator-may be somehow relatedIgnition switch or other items that turn on the fuel pump,fuel pump relay on a 20 year old vehicle !!!

Here's how to replace blower motor.

not sure of model but i would check the relays for the roof if they are all ok its either come of its runners or the cable could have snaped or motor goosed but should be able to close manually i have a merc c180 if you take the interior light lenses out there should be a small hole some where for a socket or screw driver to go so you can get it shut hope this helps ivan

doesn't fire??? you should check your battery, if it is fine, you can check the starter and ignition. car diagnostic tool

The head torquing sequence for any cylinder head is as below, continue the pattern if there are more than 10 bolts:-


10 6 1 3 7

8 4 2 5 9

Start at the middle two bolts and do your sequence at least three times, first at about half the torque, then the full torque value at least twice. It is good practice to re torque the head again after about 1000 km (600 miles), but this is often disregarded due to the problems of getting to the head bolts.

The bearings in the turbo may be shot. Check the shaft in the turbo if you can wiggle it around its bad and will need to be replaced or rebuilt.

The filter is located eather under the car at the driver or rider side door.

Other probs can be
Bad fuel pump
Clogged air filter.
Clogged injectors
Water in the fuel tank.
Clogged catalytic converter
Bad MASS air flow sensor
Bad Throttle position sensor
Timing is off

Check the imobiliser on the car first. Second Cam pick up, third crank pickup. Both pick ups should give a puse on an anologue meter. If one doesn't you have your answer!

It is most likely going to be between 5 and 15 degrees BTDC. I would put it at 5 degrees BTDC. At idle, if the motor is extremely quiet, but the exhaust loud, move it to 10. As you advance the timing, the motor should become louder and the exhaust quieter (at idle). As you increase RPMs, the motor should get quieter and the exhaust louder. This is only true with an injector pump that has static timing (does not automatically increase with increased RPM).
If your engine has dynamic timing (automatically advances with increased RPM), then I would set the timing at 5 degrees, test run. Maybe change to 7 degrees, test run...etc. Basically, don't make dramatic changes with the injector pump timing if it is dynamic. I hope this helps.

The problem is probably the 'flap' of metal that's popped up, just above the where the handle is.
The runners/rails have undoubtedly corroded, and now there isn't anything to pull it down.
Luckily, as a 'Get the roof shut cos it's p*^%g
down' solution,,.
You can just hold your finger on the flap, to hold it down, in between the sunroof, and hole as you shut it.
Just remember to remove your finger Before you finish closing the sunroof.
Happy motoring.

You will almost certainly, (I say almost, because sometimes they seize on) need a ball joint splitter.
There are different types, but a simple to explain one is, the one that looks like a tuning fork.
As you will have to align the wheels afterwards anyway, it doesn't matter if you leave the track rod end attatched to the rack at this point.
Undo the nut on top of the said 'bush', but don't remove it totally yet.
This way you can hammer the top of the nut thus forcing it free, then unscrew little by little while hammering it through as neccesary. Alternatively, you will need to use the splitter to seperate it from the hub mount.
Good luck with that:)

You have 3 choices. 1 buy one from the dealer, 2 buy one at some place like Best Buy also buy an installation kit, 3 buy one at a junk yard.

Replaceable Bulb 1985–89 200 SERIES AND 1987–89 700 SERIES

1. Make sure the headlights are off and the ignition is OFF.
2. Working from under the hood, release the clip and remove the wire connector from the back of the lamp assembly.
3. Unscrew and remove the large locking ring on the back of the headlamp.
4. Remove the bulb and its holder; replace them as a unit WARNING
   When installing new bulbs, never touch the glass bulb with your fingers. The grease will develop a hot spot on the bulb and radically shorten its life.
   
5. When reinstalling, make sure that the bulb sits properly in the reflector assembly. Tighten the locking ring and reattach the wiring connector.
