Check Oil Pressure Gauge On
So I have a 6.0L 2004 (late 2004) that is running fine. I was driving home and the check gauge light flipped on while sitting at idle at a stoplight. Noticed that my oil pressure gauge which is always right in the middle dropped to none at idle. I hit the gas pedal and the pressure returns to normal according to the gauge and the check gauge light switches back off. Then at idle flips back on again and pressure drops??
It has been hard to start the past 2 days, taking 2 attempts to turn over. 1st time it just cranks and cranks, 2nd time it cranks then fires and runs fine.
1 week ago I was stopped at a light and the truck just died, threw it in park, and it started back up again, didnt really think much of it at the time.
Another issue that happened this past week is the A/C is blowing hot air and smells bad (never smelt before), I dont see how the 2 can be related (figure its just the a/c needing freon or whatever) but just incase keep that in mind if something could be effecting the both of them.
No check engine lights or anything else going on from a diagnostic stand point.
Batteries are fine, Alternator just replaced 6 months ago (brand new) FICM has been resoldered about a year and a half ago. All other dash gauges appear to be normal. Oil level is fine.
Any sugestions on where to begin, praying its not the high pressure oil pump. Maybe ICP Sensor or Injection Pressure Regulator Valve? Does this sound like the right path?
Thanks in advance.
