Check fuel pressure at injector rail. Regulator may have failed. and get a new mechanic.

The injectors open and close to feed fuel to cylinders based on data they receive from various censors. If the wrong info is fed to the ecm, this results in the injectors opening too long or too short what ever the case may be. Check out all of the sensors involved in feeding the ecm - Example: if there is a cold start sensor that is not working properly too much fuel will get in there and ......................

If auto, did you check the neutral safety switch? If stuck open, car will not start.

While you were making repair a vacuum line may have pulled off or gotten damaged, check all vacuum lines for leaks press the helpful button and check link, How to find vacuum leaks and easily

there will be no sound , no fuel pressure and it will not start however a bad fuel pump may be the result of other failed units including the relay , pressure regulator, wiring , EVAP system so run the fault codes first to eliminate all other possible causes for the pump not working

what about having the fault codes read ( should have been the first step) the money that you have spent may have been wasted if the timing belt is broken, the immobilizer is operational, cam.crank position sensor problems , no fuel pressure from faulty fuel pressure regulator

Emissions, somewhere, lots of possible causes. Usually a bad fuel to air/mixture causing the sputtering from the fuel not properly burning. Look for any error codes first and fix those first. A MAP is easy to change and cheap so often people replace that first if needed and move on to other emissions parts.

1. It might be that when you changer the battery post you might not have connected all of the leads on the positive post. You might also check for blown circit breakers caused while changing the terminals.Try using a dc tester and search the main breakers for power. If you have the manual it shows the breakers and links in the bulb replacement section. JOHN-LA.

check for a broken wire inside the boot that runs from the drivers door to the body.

With no antenna or bad antenna you would get a hiss instead of music when using the radio, but when playing CDs you would hear music. If the amp or wiring or all of the speakers have a problem, it could stop all sound.

Putting the battery in backwards can cause all kinds of electrical problems. There is a fuse block under the hood and you should check those fuses. Also there are fused links (wires) that are designed to fail and they are hard to detect. This could be a very expensive repair.

Hi Fredrick, If petrol has mixed with the engine oil it is a symptom which usually points to one or more of the injectors leaking. The fuel is pumped continuously into the combustion chamber and is leaking passed the piston rings into the sump. Do not try to start the engine! Have the injectors replaced and then drain the engine oil and replace the oil filter. It may be a good idea to start up and let the engine idle for about fifteen minutes and then replace the engine oil and filter again. Then off you go and happy motoring. Regards John
