What would cause my temp gauge on my 1989 Ford F-150 not to work
Temp gauge stays all the way to the left while engine heats up

Four-wheelers welcomed the introduction of automatic locking hubs on the 1989 Ford F-150. Buyers had their choice of a number of powerful fuel-injected engines: a 4.9 liter straight-six, a 5.0 liter Windsor V-8, and a romping 7.3 liter International Harvester diesel that churned out 180 horsepower.
The 89 Ford F150 was offered in XL, XLT, and XLT Lariat trims. Cab configurations included an extended-cab supercab, as well as a 2-door setup; short-bed and long-bed models were also available. The powerhouse pickup was perfect for farm and ranch uses, and the 4-wheel reliability delighted the off-road set.
You'll still find plenty of these reliable workhorses on the road; with plenty of muscle and iron, the 1989 Ford F150 remains a favorite with tuners and project truck junkies alike. The 89 Ford F-150 isn't likely to be a hit with Al Gore, though; without some aftermarket modification, you're looking at a thirsty 18 highway/16 city miles per gallon of gas.

My 1989 FORD F-150 5 Litre V8? Thanks in advance!
So when slowing down to turn ( like pulling into my driveway) my truck dies. Fires right back up, but it still does it. I've tried advancing the timing from the distributor but that did nothing but use more gas. 1989 ford f150 with the 302. Any suggestions or ideas would be great

Someone tried to replace the positive battery cable on a 1989 F150 4.9 6 cylinder EFI. When you try to connect the negative cable sparks fly
