As some systems need input from oil pressure gauge,mount a tee fitting in the original hole where the sending unit is. attach the original sender to one side of the tee , the new sender for your gauge (or line for mechanical gauge) to the other side of the tee. Make sure that the line or wire is away from anything hot, and be careful going through the firewall that you don't drill through anything you need (like the heater core) Use a rubber grommet in the firewall hole to make sure sheet metal does not cut through the wire or line where it passes through.

    I've got the same engine but it won't come home till about 130AM. The manual is also in the trunk...Soooo. I'll post back when I look at it sense in trying to remember where I saw it. Car would have been here but nephew whacked a deer with it last night and wanted to drive it to work to see if everything he did this morning to clean out the mess is OK now.

1999 suburban gage oil pressure is 0 when it warms up. rpm drop to 3-4 rpm when oil pressure goes to 0. Sounds good, runs excellent -no noise. Actually it sound better then most new cars. It is so...

I looked at info for 1500--5.7L engine.
6 psi @ 1000 rpms
18 psi@2000 rpms
24 psi @ 4000 rpms

Sometimes, you can use analog gage in place of oil pressure sending unit and double check oil pressure that way. If oil pressure is actually low, if high mileage engine, I doubt replacing oil pump will help. I just wanted to add, check oil pressure engine warmed up.

93 Grand Am 3.3, engine dies when hot

Start checking air intake and air filter,

The ECU (car computer module) must be connected to a code reader and scanned, with engine light on, probably it is a computer problem.

93 Pontiac Quad 4 No Oil Presure

There will be one of three things wrong:
1) The oil pump lost prime. This engine uses a gerotor type pump and long periods of sitting allows the oil to drain back to the pan.
2) There is a restriction at the oil pickup screen or at the passage between the block and head. There is a check valve in the block (at the head gasket, there is an opening) and there could be trash blocking it.
3) IF you're lucky, its a defective sending unit.
Until you know for sure, don't run it. Install a mechanical guage, disable the ignition system at the module plug, and crank the engine. Some pressure should register on the gauge, if only 3-5psi. If it doesn't, remove the oil filter, take a quart of oil with a nozzle on it and force oil back into the outlet port of the filter housing, fill the filter completely, then spin it on as quickly as you can. Some oil will be spilled, but this is a step you want to take before tearing into the motor. Another quick way is put approximately 10 quarts of oil in it and with the ignition disabled, crank it over and see if the pressure comes up. (GM sent that as a bulletin on Northstar engines that lost prime. The down force of the pistons will force the oil to go to the pump.) JUST BE SURE TO DISABLE THE IGNITION. Hope this helps...

I have a 2000 Jeep Grand Cherokee and the oil gauge is going from 0-50 psi. There is oil in the engine. Should I be looking at the gauge or the pump for the problem.

the 1st thing to do is hook up a mechanical test gage and see what the pressure really is, the one used in the truck is electronic and u could have a sending unit problem, if the mechanical test gage show the same readings u will need a new oil pump, this assumes the engine doesn't have any bearing knock type noises

Check gages light turns on and doesn't go off. Already had the oil changed, the oil pressure needle keeps marking 0. It had the same problem once but I changed the oil and kept working fine; then about 2...

At this point I would strongly suggest that you have your mechanic hook a mechanical oil pressure guage to the engine and make absolutlely sure that the pressure is up to manufacturers standards. It may simply be a failing oil pressure sending unit, but, until you know, it could turn out a lot more expensive! Thank you, Dana

My two thousand jeep starsts then shuts off engine light comes on check gages what are the gages

You probably recently had a new key made, and the Jeep ignition is chipped. The key has a sensor, and must be programmed to match the ignition. Some will start till you put it in gear, then it shuts off.

What is the check gauges light

CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

Oil pressure gage

At idle, at operating temp is there any ticking from top end of engine? Are there any knocking noises brom bottom end?
If no noises, change oil and add some Marvel oil to clean out galleys. If that dosent work, change oil pressure sendingf unit. Also, if you have a mechanical oil pressure gauge, hook it up and take a direct reading. Oil pressure (in any vehicle) at idle should NEVER be less than 15psi. Generally in 4.0 jeep engines it's never less than 30, with a high reading at driving rpm of about 40-60! (but, you did not mention what engine you have)
