I have been working on this car for about a week now. The car will start up and idle fine, but at about half throttle the car boggs down and wants to stall. Sometimes it stalls and other times it picks back up. The fuel filters have been changed and there is fuel at the injector rail and it will spray out, but the pressure will not read. I have no clue where to go because the pump will make noise and sometimes the throttle will respond but sometimes it doesn't.


Please help!

Thanks!
 


Actually part of the problem was the fuel pump. Now there is a problem with something electrical. If the car doesn't start on the first turn of the key it will not start for about ten minutes and the throttle response is not always there. The previous owner had a new computer put in, but there is still issues. Has anyone else had these issues, and if so how do you solve them?
 
unless there is a something that has been messed with or something added to the car an electral proplem is unlikey compared to a mech problem, in my experience. are you sure that the fuel pump is good? and sometimes if theres not enough gas in the tank to keep the pump cool it will get over heated and burn out, so atfer driving for awhile the car will die and both it dies it'll run very poorly
