Bogs down

I just changed my fuel pump and I am not getting good acceleration. It still bogs like it did before I changed my fuel pump. Heard it may be air in the line. What do you suggest I check?

Engine Performance problem
2002 Hyundai Elantra 6 cyl Two Wheel Drive Manual

Hi I Bought a Hyundai Elantra 2002 model second hand in 2004, I have had a few issues with it that have all seemed to have passed before I had an opportunity to have them the checked the latest two issues have become a real pain.
Issue number 1
The car is having a real problem accelerating, If I am stopped at traffic lights or slow to turn a corner or in peak hour traffic, it takes a very long time to reach the speed limit and struggles to initially accelerate, to the point that I have to maintain the vehicle in 1st gear to be able to get going and get to the speed required. The revs are high whilst this is happening. I have noticed that the car responds well to pumping of the accelerator which has led me to think that it may be a fuel line issue?
Problem 2
Front head lights keep blowing, and the radio speakers flick from left to right and I get an electrtic shock from touching the consol beneath the cd player.

I look forward to hearing your diagnosis.

Thanks

Jasmine

Thank you for the quick reply! Bugger that clutch. It has been a little funny since I initially bought the car.

I am losing power when going up hills and when you first pull out. The rmp's are fine, it idles fine, but just looses power. I can have the pedal all the way to the floor and not pick up speed.

Take top timing cover off and check belt condition if you haven't already changed it. If that's not the issue check fuel pressure if fuel pressure is less than 49.8 psi you have a fuel issue. Then change fuel filter if you haven't already then recheck fuel pressure. If that still doesn't fix it check for a fuel blockage and finally key in on the fuel pump. Next check for a clogged cat or resonator. Hope this helps
