If you still have the 2.5 downpipe, will it bolt onto the stock Turbo? If so, price shipped to 19002, I can have the money to you later today

Well the E3s were on sale and the only plugs they had in stock for the quest, but the pump is relatively loud, the more I think about it probably clogged fuel lines... the filter is new up front, and from the tank doesn't look bad. But I haven't actually checked the lines themselves.

I was thinking that as well, and I'm sure having a battery that doesn't hold a charge for more than a couple days isn't helping. Well it cannot be a clogged Cat, because I don't have any exhaust on it from the turbo back (just took it off). Fuel pump isn't bad second one, runs fine. Brand new E3 spark plugs just changed. Brand new Fram Air filter. I replaced the MAS, ECU, Knock Box because once I do get the car running right I'll have that stuff already upgraded.

I can hear the fuel pump run from the driver's seat since it has a very distinct whine while running. The cut out happens anywhere from 5k when the engine is still cold and just started, to 1.5k after its been running and warm then it'll cut itself out.

I still cannot figure out what this problem is, I have swapped my ECU and Knock Box to one from an 88, swapped my MAF to a 1G, right now I have the exhaust completely off to check the first cat seeing if it was clogged and it'll run, but same problem as before. I have the fuel pump connected to the stock wires.

Do you still have that downpipe?

How much for the 2.5 turbo-back ?

That may have just been my camera, the car sounds good in person, just putts out when the fuel stops flowing. Could it be something in the ignition system? I doubt the coil, because that would probably just stop it from running altogether, but what else could be possible?

Do you still have the Distributor and 1g MAF?

The only wires that he added was a power cable that ran from the battery straight to the relay and an extra ground cable, it still has the stock wires from the original pump. I believe that the pump isn't running because when the car is started it has a whine to it that you can hear clearly from inside the car, when you rev it up slowly you can still hear this whine. But when you just press the pedal down the whine disappears and comes back a couple seconds later. The reason I can hear this is because I have not actually had a chance to drive this car anymore than around the block since I have bought it. I know that it's not the spark plugs or wires they're brand new, also wired brand new injector clips after doing these 2 items the car ran better, but still not right. I checked in the distributor, looks brand new (confirmed with previous owner that he replaced the cap and rotor in attempt to remedy the problem). How can I check the vacuum advance, or the governor plate? I have been replacing the filters as I get them, they don't seem bad overall. I am hoping its not a bad head gasket, as of right now I have no reason to believe it is, although it wouldn't surprise me. EDIT: Would it be a feasible option to try another ECU, as I do have an extra anyway o.O

Alright, so I haven't started the car in ~2 days and when I did a couple of minutes ago as soon as I give it any kind of gas the fuel pump shuts off causing the engine to stutter and stall. It does the same with the MAF unplugged, although it'll run a few seconds longer. I haven't had a chance to get to a yard yet to find a new MAF.

Yeah I was reading the 1g MAF upgrade forum, I'll make sure its from a turbo, Thanks Jimmy. Just got to hope that they have something at the yard.

It is still a stock MAF, I was thinking about grabbing a 1G MAF from a junkyard and upgrading to that.

Alright so I took a video to see if this might help since I am horrible at explanations. http://www.youtube.com/watch?v=kf27J8H0Ltc I really hope this helps as I am now lost, I put my Walbro 255 on and I thought it was running better, but it just took longer to get this problem.

Yeah I thought the same, but then when I tried ordering it they sent me a part that doesn't go to my car. The map sensor is built into the maf isn't it? aka the brick in the intake.
