The seat release straps should be on the top of the seat backs on the edge by the C-pillars.

Yes a broken chain could sound like and cause a 'no start' condition. Unfortunately I believe this is what's called an 'interference' engine. In other words, if the chain slips or breaks it COULD cause the tops of the pistons to come into contact with the valves. Bending the valves and possibly causing piston or cylinder head damage. Also if I'm not mistaken the water pump is also run off of the same chain. So IF you find the chain broke or slipped it may or may not have caused serious damage to other engine components. The water pump isn't a big deal but the valves, pistons, or cylinder head could add up real quick expense wise. Being attempted starting has already occurred (which is understandable as that's the first reaction when a vehicle stalls) any damage that may have happened is already done. Now it's a matter of diagnosing to see how bad it is. When attempting to start the engine it will turn over with a rather non-rhythmic sound if the chain broke or jumped time. Sorry for the 'gloom and doom'. Simply trying to give a straightforward answer.

Hard to tell without seeing it but I had a freeze plug leak but you should be able to see if there is moisture in that area. We popped it out and replaced it ourselves.

Check the relay that powers the high beam, if memory serves me the relay is shared between those two circuits.You can swap the relay with a known good relay to prove if that is the issue.

clogged exhaust (catalytic converter ) Have exhausted bake pressure tested .

It just pulls out and plugs back in.

Sounds like a rotating electrical device not connected to the drive belt, like a rad fan. Not sure if this engine has a vacuum pump, but that could also be what's making the noise.

it sounds like they may have damaged the fuse box where the relay for the blinkers is. or put a relay in the wrong one some relays look the same but are a different colour, but have the same pin out putting the wrong relay in the wrong slot could cause this.

Do yourself a favor. Take it to a shop that installes the systems.

How long since a tune-up? To check for some codes, use a jumper wire between A and B terminals at datalink connector. Then, turn key just till dash lights come on. The mil starts flashing, you count the flashes to get the codes, your looking for two digit numbers. This is 12 pin data link connector obd1.

When in park does it rev up or not

simple test if you have a vacuum brake booster put the hand brake on and start the engine if it idles bad --possible vacuum leak from gaskets , vent controls sensor problems if it idles fine , put the foot on the brake if it idles bad now -- replace the brake booster

Did your mechanic suggest you go to Fixya and ask for some help for him or her? If not, do you think he or she is going to accept advice from what someone may provide here? We have no idea what he or she has checked and what has been found. Let the mechanic do what he or she is supposed to do. If you get your car back because your mechanic has decided he or she can't fix it, then post another question with details on what has been found and what has been done in attempt to fix it.
