    some gauges in the inst. cluster have been known to be faulty, but more likely the printed circuit on the back of the inst. cluster has a break in it. a simple continuity check between connector and gauge will tell the story

SOURCE: 1991 4.3L GMC Jimmy S-15 will not start. Turns

You need 3 things.
Compression
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 13-13.5 lbs on your TBI
If you have all 3 then move on to injector pulse to both injectors.

Keep me posted and recheck your spark plug wire to make sure they are not crossed. firing order 1-2-3-4-5-6 cylinder # passenger side 1-3-5 front to back. cylinder # drivers side 2-4-6 front to back
distributor #1 is located at the 7 o"clock and rotates clock wise so next distributor post on the right working clock wise is #2. Good luck and hope this helps.

SOURCE: where is the oil pressure sending unit?

The oil pressure sending unit is located on the engine block, passenger side by the Distributor. Good luck and make sure you get the right sending unit, there is the simple unit that only turns on a low oil pressure light and the other will send signals to the oil pressure gauge.

Temp gauge not working 1991 ltd crown vic


Find temp. sending unit on engine. If one wire type ground that wire to good engine ground, with key on gauge should go all the way to hot. If it does replace faulty sender. If it doesn't than you have bad gauge, wire or connection. ( If replacing sender, make sure engine is cold. remove radiator cap to releave pressure and you will loose antifreeze when it comes out install new one quickly and don't use teflon tape as this needs to be able to ground to engine.)

Engine overheating...radiator?


If the radiator was blocked you would have a very hot motor. I am thinking that the wire to the temp sender unit has broken or fallen of and is shorting out somewhere as this sends the gauge to full overheat. If ok replace the temp sender unit as it probably has a internal fault.

1990 gmc K1500 5.7L, temp. gauge not working:


To review, you have two temp sensors, one for the gauge on the dash and one for the computer. If you unplug the sensor for the computer the reading will be minus 30 degrees or over 300 which will make it very hard to start. Unplugging the sensor for the gauge would have no effect on the computer.
According to the wiring diagram, the wire for the temp gauge is green, and the wires for the temp sensor for the computer are yellow and black.
