Hi everyone, I had a new fuel pump installed in my car a couple of days ago, it was running fine and now it wont start. the fuel pump seems to be working (I can hear it) fuel pump relay is fine, fuel filter is good. it threw a p0102 (MAF low circuit) and a p0122 (TPS sensor) could this be the cause why my car doesnt start? or should I switch fuel pump? fuel regulator?

And here is what I found wrong, Post #49....
Well, dropping the fuel tank round 2....
Turns out the fuel hose from the pump basically exploded at the tip, the picture was taken as soon as I pulled it from the tank, untouched. Im glad I didnt add more fuel to the tank because that ****ing thing was heavy and it sucks doing this by yourself. I cut about 3/4" off the hose and plugged back together. Once everything was put back together I primed it 5 times and started right up.

Anyone doing the install and following the document I posted for install, I reccomend you cut 3/4" off the hose from the pump because the entire assembly compresses once locked down to the tank. This caused the hose to bend. The bending combined with the hose clamp causes the fuel line to rip and pop off as seen in the pic above.
This picture is pretty motivating for anyone to do the install themselves. I did the entire thing in 2 hours, by myself, in a parking lot, with the car only jacked up that high.

And this pic shows where I mounted the hot wire kit and grounds on the left.
