Replaced fuel pump, car fired up running nice and smooth, 15seconds into startup it died, started it back up, ran 15 more seconds and then dies. The new IAC we put on makin a weird noise, so we put back the old one. wont even fire off old one, Defective new IAC???, Bad TPS? Dont make sense, getting fuel, geting spark, new IAC, new MAF, new gaskets on the upper end, new water pump, new fuel filter, new pcv, quadruple checked the vacuum lines, thinkin maybe we bumped one off, new plugs, new wires, , running out of things to replace here, LOL. Getting the essentials for it to run, but we think IAC may be problem. Any other things to look at? We may be over looking? SUggestons would be apprieciated. Thanks in advance. Ill say this once again, never had a car give me this much problems lol.
