I installed the walboro fuel pump and the car ran for a good 10 monutes with no problem, then heading down the street the car went lean as hell, thank god that a friend lent me his laptop to see what the hell is going on. Idle was right around 19:1 in the afr so I dumped in almost 26% more fuel just to get the idle back. These are on stock injectors.

I got the car rolling in first gear shifted to 2nd and tap the gas lightly and it seemed that the MAF wasn't hooked up but it was, I checked it 100 times to see if it was connected properly. The car has no power what so ever if I try and step on the gas. Is there any tricks or hint to get this thing running right?

 

I'm assuming you have a WB? Was the fuel pump the only thing you install? Did you retune? Sounds like your FP is bad or the connection is loose.

 

Maybe you connected the two wires backwards? I just installed mine today and its working fine. Or possibly its the FP? Is it new or used? They say that if you reuse your stock pickup bag, that decreases the life of your FP dramatically. What else do u have done?(tuning?)

 

Well I took out the walboro and put the stock one back in, works just fine now, so I am guessing i just got one of the bad ones.

yes I was using a WB and it was around 19:1 all the way to the too lean symbol on the tuner. Yes the FP is the only thing I did today, the car just wasn't getting fuel. I will try and ohm out the FP and see what it reads and compare it to another one. Thankfully I bought the pump local, and it was the 342 pump. Kinda funny that the car ran fine then right before i took a right turn the car stuttered and it felt like the MAF wasn't hooked up. When I checked code I was given a p0108, p0118 and another one I can't remeber off the top of my head. I think it was a 102, I wrote it down somewhere.
