i recently put in a walbro 255 pump and new fuel filter. im possitive i hooked the pump up properly but the car wont start now. i put in 2 gallons of gas in the tank also and nothing. what could be the problem?

 

Hook up a fuel pressure gauge to the schraeder valve on the fuel rail, and report back with fuel pressure reading during cranking.

 

Just a note:
I have pulled a pump back out after it was changed in a friends car. I found that he had not hooked the the rubber transfer hose up very well. I guess after starting a few times the pressure blew it off. Anyway I reconnected the line and no problems for 2 years now.

The reason I pulled the pump was fuel pressure was very low when he brought it to me...

Really need to check your pressure

 

going to check the fuel pressure, also i noticed the pump doesnt even make a noise when i turn the key. maybe i didnt connect something
