Honda Civic 2008 after replace blown head gasket car take long to start

ANSWER : If vehicle is hard to start after the engine head was removed then you may need to double check the timing of the timing belt was set correct and the engine has no codes for the cam sensor set because of it. You may have timing off one tooth. You should also check engine compression.

ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : Hi there:

In most cases when a cylinder head gasket has been pushed due to overheating, it can cause additional damage to valve train hardware; most of the time problems with valve guides. However, if you’ve double checked all hardware; you might want to look into the ignition system; perhaps the crankshaft position sensor is damaged (which happens most of the time during an overheating issue). If you can’t find the source of your issues, feel free to contact one of our local mobile mechanics and have them complete a car will not start inspection; so they can help you diagnose the problem.

ANSWER : Hey there. This may also be caused by what is called the fuel pressure regulator. This is a unit that helps to maintain the fuel pressure at the proper level. When this is not working properly, the fuel pump may be pumping properly, but the fuel may not arrive at the fuel injectors at the proper psi. When this happens, this can cause a lean fuel condition which may cause the car to hesitate, misfire, or stall. If you would like to have an expert pinpoint the issue, a certified professional from YourMechanic can come to your car’s location to inspect the hard start problem and confirm which repairs are needed.

ANSWER : Hi there. It really depends on the location of the motor (meaning if it’s installed in the vehicle or loose and on an engine stand), that would factor into the price and whether this is a project one of our mobile mechanics can complete. We can complete the oil pan gasket replacement, but some of the other jobs like wiring harness, intake and rocker arm installation is outside of our scope of service. In regards to estimates for those services, I would suspect it would cost anywhere from $400 to $1,000 based on where it’s completed and what supplies would be needed.

ANSWER : If the car was out of coolant, and shut off because it was overheated, then there is a good chance that there was some engine damage. But don’t panic yet, the codes and leaks you have might be separate issues and if you are lucky, the car shut off for some other reason besides overheating. It sounds like you have several problems that have been stacking up on you so you need to have this thing looked at by a pro. You can have that done at your convenience by contacting Your Mechanic. They will send a technician to your home or office to check out your non starting Malibu and its overheating problem and let you know what it will take to solve your problems.

ANSWER : Hi there. It really depends on who is completing the repairs and where it is being completed. If a mechanic in a shop is replacing spark plugs on your vehicle and the starter, it could be a project that lasts 4 to 8 hours. Our mobile mechanics can also replace spark plugs and replace a fuel pump for you at your location, which would make it easier on your schedule.

ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
