Ford electrical.......good luck. Just want to say that many times when this happens, it is the spark modulator on the distributor. This can be tested before you buy a new one. You take it off and up to auto parts place. Autozone will work great for this.

How do i prime the oil pump in a 99 e250 5.4L


Oil pump is self priming. You do not need to prime it. If not showing oil pressure, the sensor is probably defective. Make sure oil level is not low. If the vehicles water temperature gauge shows normal when running then oil pump is working fine. If it goes to the overheat mark then you may have defective oil pump, which is rare. Most temperature gauges go past the middle when you first start up but then drop back to normal once the engine thermostat opens up. Hope this helps.

the first thing to try is turning the heater upto full heat(a/c off)if the temp guage goes down THEN CHANGE THE THERMOSTAT...(hot oil,if too hot, is thinner than the normal sae rating so the oil pressure will be lower.otherwise no real problem.

2002 2.5l no oil pressure on gauge. Runs fine...no


You better put a manual gauge on your engine and make sure you have oil pressure. Could just be a faulty gauge or sending unit but I sure as heck would be checking it with a manual gauge.
