To keep things short, about 3 months ago, my truck experienced multiple problems in one day including, stalling, knocking, misfires, low oil pressure readings (oil pressure resets after restarting car). About a 2 weeks into working on the car trying to fix the problem I started to notice a problem where my car would take 10-15 seconds to start.
Anyways, I took the engine apart, replaced the timing set, lifters, pushrods, oil pump, and cleaned all of the oil sludge out of the heads. Along with this I also replaced all of the injectors, coils, and spark plugs. Before starting the car I put in a new oil pressure sensor along with a new crank position sensor, camshaft position sensor, knock sensors, and a new map sensor.
After the first start the car ran better than ever with amazing performance except the oil pressure gauge kept dropping to 0 (I promise you there is oil pressure because the car is basically silent) and the car still takes 10-15 seconds to start. Since the rebuild I have purchased a new battery and a new ECM, neither of those have worked. I suspect the hard start is the fuel pump because this had been a problem in the past, keep in mind, I'm on my 4th fuel pump.
When it comes to the oil pressure gauge I have no clue what could be the cause seeing as the oil pressure sensor is brand new. Help would be greatly appreciated. Thank you!
