Engine Problem

[cgmacll]

I have a 2003 merc 4.3L with a 2003 merc alpha one drive. I am doing the normal maintenance on it and have changed the distributor cap,the ignition sensor and a new rotor sensor wheel. The problem is that the motor will not start or run. It trys to start but will not. I did have to take the hole distributor out and I did not move or start the motor at all it is still in the position it was when I put the new parts in. does anyone know what I did wrong.

Did you have the rotor pointing in the same direction as it was before? If not, there is your problem.
One other note, changing the sensor is not a tuneup item. They get changed IF they go bad.

Re: Engine Problem

I think! I put the distributor back in the right location. yes, you're are right you normally change parts because they are broke. In this case it was, because I broke it trying to get them out. I think that the timing is off and I need to re set it but I kinda know how. the old cap sensor and rotor have been in for at least 5 to 7 years and I Though that it was time to change them. I also can not find the manual on my engine again it is a 2003 V6 MerCruiser 4.3L 190hp and a alpha one drive. I need to know how to re set the timing.
