1990 Ford F150 - Page 9 Questions & Answers
F150 shut off driving down the road
If you're still having the problem, replace the module on the side of the distributor. Mine drove me crazy until I replaced the module.. There is not much diagnostic information available on the old OBD I system.
HOW DO YOU PUT ON THE GASKET FOR thermostat housing ON 1990 F150
Find the upper radiator hose, and follow it to the engine. it connects to the thermostat housing. drain some coolant and remove the two or three bolts to get to the thermostat (recommend replacing every time you have this open). Clean the engine mating surface and thermostat housing surface. then use the new gasket, or RTV and bolt back down.
Timing is off on my 1990 ford f150 v8 302
There are a few ways and if I remember correctly, if you have a Module on the distributor you also have a wire sprout which must be disconnected to get base timing.That being said, those modules still had a timing mark on the crankshaft damper and a timing mark pointer. You want to have the crankshaft visibly marked and the pointer at the DEGREES recommended for the motor. You will see TDC on most dampers and then advance it maybe 6 degrees as marked.Assuming you are close to begin with, AFTER lining up the parts as recommended, mark the distributor #1 plug position on the cap to distributor housing so that the #1 plug terminal is known when the cap is temporarily removed, wires intact.Then see where the rotor is pointed and remove the distributor and clock the rotor to align with the mark you put on the distributor housing. If you have a gear drive, the gear will need to be moved slightly for the rotor to twist into place when the distributor is seated. With a timing light, check where the spark is occurring for #1.You may be close enough for the engine to start.Other ways involve removing a plug(#1) and turning the engine until compression pushes your finger away from the cylinder hole. Line the timing marks up per specs, do the same process for the distributor rotor and try it again.If this still does not produce the results you want, make sure the plug wires were not switched. Finally removing the valve cover to observe when intake and exhaust are both closed will help, but it is a lot off unnecessary work to be avoided.
Oil pressure light on
If the oil level is OK, then replace the Oil Pressure Sensor, if the engine still has good Oil pressure that should take care of it.
How do I set idling
fuel injected motor. not adjustable. if idling high, replace throttle position sensor. fixes that problem 90 percent of the time.
Wont start or has problems starting
Chek fuel filter first, and replace if it hasn't been changed in a while. Then if it still has problems starting, check ignition module. Make sure all grounds are tight and making good contact as well.
