All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.Every engine requires spark, fuel and compression to run. That's what we have to look for. These are the basics that need to be tested and will give us the info required to isolate a cause.1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.4) If all of these things check good, then you would need to do a complete compression test.Once you have determined which of these functions has dropped out, you will know which system is having the problem.

you have raise vechicle high enough then you have to lower frame to remove transmission

water pump, fuel pump, oil pump, smog pump??????what size motor???

Could be one of two things. First is the brake light switch, located of course at the brake pedal under the dash. But usually if the brake lights work it is fine. Second there is a solenoid inside the console at the shifter. Look to the right of the shifter, there should be a slot there. Insert a key and push down to release the shifter. This solenoid is part of the shifter, so to replace it you have to replace the whole shifter, Runs from $150 to $200

When you say it turns over FAST how does it sound when it turns over, or do you mean it has plenty of battery power to turn the engine over ?
EGR wires melted is not good. Must find out why they melted. Melting wires means shorting out electrical system, not good.
Do you have spark ?, fuel to the fuel rail ?

if you have dual controls for temperature for passenger and driver, they may be set to different levels, try to push the driverside temp control switch or knob in and this will give driver control over both sides again

Ok, so do you know for a fact the tank has gas in it, and is the fuel pump running when you turn the key on ?Have you checked fuel pressure with a gauge ?

Your old sway bar made of tubular steel. New sway bar made from solid steel. You have a frame under engine the sway bar attaches too. This frame also supports your engine and trans mounts. Follow frame and there are 4 bolts securing same. Mechanic I watched supported engine underneath. Loosen back bolts though not removed. (please note sway bar has arrow that bar can only go in one direction) This maybe your problem. Attach bar to frame and fitting's. Best if you raise front end and remove both tires. Good luck

It's nothing to do with the power steering, the problem could be at the water pump. I think this is the wrong pump for the car, check it, the impeller is turning the same direction as the old one. Once happened to me on a Jeep.

check battery and connection.

Beside your shifter there should be a hole which is a release/brake over ride. If that does not work, I would check your shift cable.
