1987 Dodge Ram 50 Questions & Answers
Where is the oil pressure sending unit located
The oil pump is located just inside the oil pan if you remove your oil pan you'll be able to see the oil pump sending unit. The oil pressure gauge switch is located just above the oil pan on the engine block beneath tge cylinder head. Hope this helps.
318 engine with no spark to coil or spark plugs. how do i fix this
William, your car uses a ballast resistor that causes what you describe. This is usually a ceramic white, rectangular piece, mounted on the firewall.
The voltage to the coil has to be dropped to 8 volts, or so. Chrysler handles that with a ballast resistor and it fails.
To test, you can wire across the resistor and see if you have spark.
My recollection is one side is for the coil and one side for the wipers or something like that.
This is a common problem.
1987 dodge D-50 RAM oil
If light does not come on when key is in the "on" position, then first suspect a bad buld in the instrument panel. Find the oil pressure sending unit and ground the wire goin to the unit and see if light comes on (assuming the the bulb is good) if it does then the sending unit is defective. Replace the sending unit and retest.
Hope this helps.
How to test a coil
There are two places to check resistance. Set the voltmeter to ohms, and pull off all wires on the coil. Measure the resistance between the plus and the neg. terminals on the coil. Second, measure between the coil tower (where plug wire connects) and the negative terminal.You have to know the specs for your coil, so you will know if your tests are within the specs. Consult a repair manual for your vehicle, or ask at the dealer service department, or maybe the parts person there will know (then again, it's an '87, they'd have to look it up somewhere...).Your first reading should be low-on the order of 0.8-2 ohms, or maybe 3 ohms at most. The second reading is always pretty high, say 8,000-10,000 ohms, or 8 to 10 kilo ohms. You have to know the specifications for your coil-it would be in a repair manual. If the coil falls within the specs, it is good.
Some body unhooked most of the vaccum lines and crossed some of wires
Not sure what type of vehicle you are referring to however most vehicles come with a vaccum diagram inside of the engine compartment , either on the bottom side of the hood or on the cross member in front of the radiator. Same can be said of the spark plug wires. If they are not availablein those places , I would suggest googling the engine year ,size and yr/make /model of your vehicle or see if youtube has a video clip of firing order/spark plug wiring .Good luck
Timing
Normaly the timing numbers are on the top of the engine on the intake manifold or underneath the caruburator i hope this information helps.
1987 Dodge Ram 50 wont start and no compression
Bad news more than likely you warped the head and blew the head gasket. remove the head (the one with no compression) take to a large parts store or machine shop and have them check it for warp. If it a warped steel head they can plane it down. If its a warped almum. head you might want to get a new or good used one. save yourself some over heading problems down the road.
I need to know if there is any cross over for a
