Hi everyone... I'm new to this site. Actually my first membership to any forum ever. I was really hoping you guys could help me out with this issue. I bought this 05 TB I6 4.2 about a week ago for 1500. Only 78k miles. I considered it a steal. He said it wouldn't start... I was able to start it but it stalled 3 seconds later, if that. Saw that the gas gauge was Empty with light on. He told me he put gas in it and that it wasn't completely Empty and it had been broke for a while. I know about the recall for the fuel pump/fuel gauge so I figured it was an easy fix along with the RPM gauge(needle stuck at 6oclock position) and oil pressure gauge. I was wrong. 55PSI on the fuel rail... I have good spark. Found 2 pressure switch sensors installed... One installed in the block acting as an oil plug and another one connected to the ECM with a screw in it, like someone tried bypassing the system... I pulled both plugs and installed a brand new one. The only code it throws is P0068. Checked MAF. Vacuum lines. IACV. Pulled and cleaned the Cam Sensor. Everytime I go to start it, it does the same thing. No more, no less. Everyone is telling me to check for compression... It only has 78k miles on it though. Isn't it a little too early for bad valve seats and rings? And even if I had a dead cylinder wouldn't it still start and run for me than 2-3 seconds? Any comments, suggestions, or questions for me would be greatly greatly appreciated. Thanks everyone.
