Beginner question.

Hi, I'm working on a 1990 f-250 with a EFI 460. I got a couple of beginner questions: Where is the oil pressure and/or oil level sensor. Also where is the coolant temperature sensor or sensors? I'm fixing this pickup up for my grandpa in my spare time and neither the oil or coolant gauges in the dash seem to be working. I took a brief look around the engine and found what looks like two coolant sensors in the intake manifold, why are there two? Or am I confusing myself? I'm still searching for the oil sensor.
Any advice welcome.
Thanks.

The coolant sensor is in the intake on every motor I've messed with

The oil pressure is right above the oil filter as I recall been a while since I replaced one

The coolant sensor is in the front by the thermostat,should only be one wire going to it.

The oil pressure sender is behind the throttle body with one wire going to it.

Ok, thanks guys. I got the coolant sensor replaced and working again. Still haven't been able to locate the oil level sensor to fix that yet.

Found this after a bit of googling:

there is another temperature sensor on the passenger side of the engine block,

on the lower part of the block,

near the exhaust.

taking it out drains all of your coolant.

OP: not one of the above threads are relevant to your 460 gas motor. I think the tachometer gets its signal from within the distributor. Other's more familiar will chime in hopefully.

OK TROLL (goingboarding), thanks.

no need to judge someone just because YOU find my information irrelevant,

thats why some others might not post because of internet "gods" like yourself

if you were half as good as you thought you were, you wouldn't be on a truck forum asking questions, and hoping people would give you the answer....

its posters like you that make the board really inhospitable

to the OP, use google its really easy....

I read all those threads... Yes they were irrelevant. For the fact that the idi diesels have a mechanical tach pickup on the block. A gasser has the pickup in the distributor. Something a diesel doesn't have.

Inhospitable? Not so much, just letting the OP know that the info you posted would net him no appreciable gains toward his issue.

to the OP, use google its really easy....
​​​​​​​To the OP if the tach was working before your other repairs, check to see if you pulled a connection apart around the distributor. That's the easiest place to begin

Its not internet gods, its members of a community who share knowledge & information. We generally like to be correct & applicable.

No body has been mean to you, rather pretty civil, restrained & on point.

Just try for accuracy & relevance, how bout?
