For the last few days i have had a lot of trouble starting my car. It cranks quickly but doesn't start until 10-20 secs. I just changed the fuel pump to a walbro 255 about a month ago. The car drives very sluggishly and hesitates alot. I also changed the plugs to one range colder about 2 weeks ago. The wires still are good and test fine. I tried the 12 volt bypass that eliminated the fuel pump ecu to try to get it to run smoothly but it doesn't help. Think the pump went bad already??

Figured out the problem...make sure anytime you install a new fuel pump use a high pressure fuel injection rated hose at the coupling point between the fuel pump and cars hard line. Its only a 2.5" inch fuel line but mine had a pin hole and fuel was leaking from that point. Also tighten the hose clamps.
