I am scheduled to be at TT tomorrow afternoon to have my car tuned by Shiv. In preparation I put in a Walbro Fuel Pump and switched back to my stock intake. After installing these parts the car won't start. It kicks and sputters but won't run. It seems as if the car is not getting enough fuel. I checked all the obvious, power connections, my MAFS connection, checked for vacuum leaks. I am at a loss. I put the stock pump back in and I am having the same problem. If anyone has any ideas on what to check please let me know. If you PM me with your phone number I can call you, that would be even easier for me to explain it to you. Thanks in advance...

check the fuel pump fuse

 

I can hear the pump kick on, it makes a bot of noise.... thatough of that, thanks though, keep 'em coming

 

You need to take the fuel pump out again and check your install. You might off not put it in correctly the first time.

 

Undo the fuel hose in the front and put it into some sort of container and have someone turn the car over to see if you getting proper flow. You can also check the pumps ouside of the tank by trying to flow water to see if they are functioning properly. Be sure to dry all the water out of the pump before reinstalling.

 

Did you make sure the o-ring was on the outlet tube of the pump before you installed it? If not, it will cause massive low fuel pressure....just a thought...

 

I figured out the problem, I feel like an idiot. When I installed the pump I took off the black plug on the base of the pressure tube, it has one wire going to it. I didn't know for sure if I had to take it out since I never installed one before, but I did. I figured out I didn't have to take it out, and put it back in, but when I put it back in the O-ring got turned sideways. This cause all the high pressure fuel to just flow back into the tank. Really frustrating but I feel so stupid now. At least I got it fixed and I thank you guys for your suggestions. On to get my cams/gears installed and have a 1+ custom tuned, wish me luck!!! Later on guys.
