Intake manifold gasket on 2.0 L 4 cyl. fails. most of the time is at number 2 cylinder , causes check engine light with lean codes and sometimes misfire codes . replace gasket & plugs disonnect battery or reset PCM (computer) VERY COMMON PROBLEM GOOD LUCK

Sure, but you have to be able to handle the contents of the coolant system (roughly 2 gallons) and be prepared to refill it with fresh coolant. To replace it, drain the cooling system first. Remove the top radiator hose from the thermostat housing at the top of the engine. Remove the bolts holding the housing to the engine and then pull the housing up. It may be stuck and you will need to pry it up gently. Do not use a screwdriver under the housing to pry it as you will gouge the metal and cause a leak later. Often a few soft taps from a rubber mallet will loosen it. Note how the thermostat spring is set in the housing as that is the way the new one will go. You will need to remove all of the old gasket material and avoid letting it get dropped into the engine opening. I stuff a shop towel in the opening before I start scraping with a plastic scraper -again this avoids damaging the soft aluminum. Once the old stuff is out, put in the new gasket, put the thermostat in (you will have already bought it and have it on hand) cinch down the bolts to be snug but not overly tight as they can strip easily. Replace the hose (maybe with a new one since you've done the hard part?) and then refill the cooling system and test run to look for leaks. You will need to get the engine up to normal temp to allow the thermostat to begin working. Might as well change all radiator hoses if they are more than 3 years old at this point. Otherwise you will be draining the coolant system again to do it later.
Have fun with it.

Distributor fault, the coil goes down in tyhem and sometimes pops the ECU.

Hello, I am going to make a few assumptions here. The vehicle has an electric fuel pump and you replaced it. The vehicle has fuel injection. The engine is actually cranking, just not starting, when you say "car still won't crank". You are getting fire to the spark plugs at the plug ends. You checked the fuel pump for power at the pump. No power, then you back traced the wire to the fuse block and checked the fuse to see if it was blown. If the fuse is good back trace the power to the ignition switch and/or ECM for power. You have power at the pump, check the ground and make sure it is connected properly. Will the pump run when someone turns the key on? Pump runs, check fuel manifold for pressure. No pressure, check the fuel filter for blockage, or replace it. Fuel pump doesn't run, new replacement pump is defective. There is usually some type of control module for the fuel pump on fuel injected vehicles. Good Luck, RAC
SOURCE: cranks but won't start fuel pump not coming on
put a small amount of fuel in the intake near the throttle plate then crank and see if it fires, if it does then it's a fuel problem, if it does not fire then pull a plug wire and put a philips head screw driver into the plug wire hold it 1/4 inch away from a good ground then have someone crank it over, you should see spark and it should be blue, if not then you have a ignition problem a bad coil or cam sensor but need to know what you found out on the two tests I told you first to give you a direction to go.
