Ceck the ignition cam sensor must be in proper position with the cam gear.

any colour will do ,just top up with neat antifreeze ,its all the same regardless of the colour

Okay you may want to check to see if the sensor on door lock cylinder hasn't fallen off from the lock itself. Pull of the door panels and check the wires at the door lock cylinder. Hope this helps.

This has to do with the front brake caliper on the left sticking or the front right is not activating. Remove the front wheels and check the caliper for proper movement and pad wear. Try to rotate the front left and note any heavy resistance. Also check all tires for proper pressure.

First check all of the fusses first and if you can't find a blown fuss than you can take it to any auto shop and they can test it for you

You probably blew a fuse. Check all your fuses under the dash and under the hood.

if replaced fuel pump because of not enough fuel pressure they should have checked the fuel regulator, could have bad fuel regulator

how did you verify fuel pressure, also what was fuel pressure?

SOunds like you have an oil leak. More then likely blow by from worn piston rings or sticking or improperly seating valve. Its so little that since the car isnt getting that hot by you running that he oil is building up and then being blown out the exhaust (similar to a diesel as they smoke if sitting for a while due to the il buildup). I would try some engine restorer (in the chrome can with black letters) about $4 4cyl, $5 for 6cyl and $8 for V8. Its worked pretty good for me when I had excess smoke.

no there is no trick but plastic and rubber will break away from metal if that is what is melted on. you will need to go to a napa or equivalent to get a replacement fuse able link. you will need to replace is and then check for bad connection because that is the most likely cause for a melted electric components. let me know if you need me to help you more in the fix.

Check for blown fuses,and turn the key on and move the shifter to neutral,see if it will start,then try moving the shifter from park to all the way to drive 1 and 2 and 3 then to park again,be sure to have the brake pedal pushed down all the way.Check for burned fusible links.Check the voltage on the small terminal,on the starter,while holding the ignition to start.See if the starter is getting voltage.Remove the negative battery cable ,for 30seconds,and reconnecting.then try and start the vehicle,if none of this will help,then the anti theft system is malfunctioning.It may have to be reprogrammed at the dealer.

re tighten the bolts or that pump was faulty take it back to the place that put it on and tell them to do it right this time!!!

Fuel tank: 22.5 Gls.

I hope helps with this (remember rated this help) Good luck.

IT sounds like he did something wrong with the wiring in your car. I would take it back to him and demand that he checks his work and makes sure that all is working properly. If he says he needs to charge I would then tell him that you are getting a lawyer take it to another installer and make him pay for all the work to fix the car. This happens all the time and it is because they wired something backwards

Most engines today run very hot intentionally (an engine is a heat pump and is most efficient when the most heat is being made, but below the heat level that will cause it to self destruct) Many competent shops have a "heat gun" that can accurately determine if the engine is too hot, or normal. If a fan problem is detected, the system needs to be tested to determine if it is the fan motor, relay, sensor or wiring/computer that is causing it. Since your gauge reading appears normal, you may not have a real problem, aside from that you can't touch the engine when it's hot, but you don't do that much while driving!
