for circuit breaker,look under the hood in main fuse box,it will be a black box.marked main fuse and relays. usually located on the driverside under the hood,but some are on the passengers side under the hood on the fenderwell. thank you for choosing fixya.com {if not a fuse} suggest a bad wiper motor,or a bad switch on the steering column}

60psi cold / 30-45psi warm is ideal. I've seen (with that mileage) 45 cold/ 20 warm and that's acceptable - anything less start thinking about a new oil pump.

Check rear light fuse and wiring.

On GM cars and trucks this is a common problem and is caused by a defective oil pressure sending unit. To replace the sending unit remove the engine dog house cover in the passenger compartment, the oil pressure sending unit is at the back top of the engine

Hello and welcome to FixYa!
You may just have a system failure. As a first course of action, I strongly suggest that you remove the positive battery connector and let it sit for atleast 5mins. or more before reconnecting it. This will reset the system and can get your vehicle back to it's normal operation.
Hope this helps and thank you for using FixYa! Have a good one!

Electrical injectors are somewhat self cleaning, in that any deposits get removed when the core moves as it fires. But there usually is no way to really clean injectors. Chemicals are not strong enough, and there is not way to get anything mechanic inside where is counts.
But you can tell how they are working, simply by removing them from the manifold, while still attached to the fuel lines.
(Careful not to cause a fire.)
Just crank the engine to see the shape of the spray.
It they are all the same conical shape spray, than they are all fine.
If one dribbles, is less, or shoots a sold stream, it is bad.

only thing i can suggest is while the engine is cold have someone run up the rpms and spray carb cleaner around the vacuum lines and anywhere else you think there could be leak. if a leak is present the engine will **** up the carb cleaner and bog down. BE SURE TO DO THIS WITH THE ENGINE COLD CARB CLEANER IS FLAMMABLE.

NO, but if the gage is not working if you were to have a problem with the oiling system you would mot know until it was to late, but a non-working gage will hot hurt any thing.

check your bulbs

check the fuses and see if you have a blown fuse for the gearbox computer but please do not ask me where they are as i have no idea because i have never seen one here in spain but look in handbook for location and what the fuse numbers are for is what i would do first

Under the hood behind the headlight assembly. Twist and pull the bulb out.

Replace the whole assembley.

check your wheel speed sensor to make sure it is operating correctly if it is bad it will send signals to tranny making late shift and causing hard shift

Please make sure you gapped the plugs to specifications. ( probably 35 thou' of an inch ) gap gages are very inexpensive. Also suspect the spark plug wires, check teher integrety as well the correct firing order. To check for short, in the dark watch for arching to ground ( visually ).

Hope that helps.

Clean the throttle body with throttle body cleaner and make sure the air filter is not dirty or plugged.Also clean the mas air flow sensor with mass air flow sensor cleaner.Give this a try and let me know if it took care of your problems.Hope this helps.Good luck.

Force that black appliance off of the 2 'snaps' on the opposite side of the bolts that hold it down.then take a wide blade cold chisel, put it up against the edge of the appliance where the snaps are holding it in place, and tap with a hammer away from the body of the van. It will pop right off with a little persuasion and won't t break it in the process. Once it's off you have one more nut to remove on the tail light to get to the bulb. When you're done, you just line up the pegs and push the appliance back on, then finish up with the nuts and you're done. Hope this helps

Hi, there are only three ways to find a solution to this problem. It maybe that the bulb socket needs cleaning to remove corrosion on inside, the bulb socket has loose wires or missing terminal or finally you have a bad fuse. You have to check these three problems out one after the other to isolate the cause of the problem...
