BORTI Posted July 2, 2020 Report Share Posted July 2, 2020 Hey guys, I have a 2008 Shelby GT500, KB SC, L&M cams, th400, etc. Anyway car runs like a raped ape. I moved to Hawaii drove the car brought it back home where it sat in the garage. Would start it once a week. Then one day it was hard to start, with no throttle response at all, then it wouldn't start at all. Fuel pressure is at 40psi, once I start cranking it jumps to 100psi with no start. I get a P2198 code. Replaced pumps with deatschwerks, new fpdms, new fuel pressure sensor, new O2s. Need some advice please. Quote Link to comment Share on other sites More sharing options...
twobjshelbys Posted July 2, 2020 Report Share Posted July 2, 2020 (edited) Chances are that it's running rich more than the sensors are bad. https://www.fixdapp.com/blog/p2198-code Did you check the MAF??? I'd stop shotgunning and take it to a dealer with the proper equipment do diagnose. Edited July 2, 2020 by twobjshelbys Quote Link to comment Share on other sites More sharing options...
