1992 f150 5.0 302 very hard to start runs poor a minute or two then runs great. Whats the problem

SOURCE: F250 spins over well will not start

Sounds like a faulty crank sensor. Can also be caused by a faulty cam sensor.

I had the same issues for most of last summer. Finally, I replaced the Plug Wires and the car has been working like a charm since. The other problem I found was that I had the wrong plugs. It seems there are only two types for the Focus, the local parts guys quoted me the incorrect part number and my fuel efficiency went to ****.

I had a the same problem. You need to check the vacum lines from the top of the intake to the fire wall, the lines will dry an crack an are easily broke. I fixed mine for now with simple straws an duck tape but its back to running the way it should. My truck was hit an i had the problems afterward, i also had a problem with my brake being too stiff i couldn't even get the pedal halfway down when running but the truck ran like a scared dog, this is what lead me to the vacums. The master brake boster hose had been tore bout half an inch out from the intake an when parked ran fine, just while moving would shift an cause my problems, After fixing this i went on to check all my lines. An ALL the lines on top were cracked or broke in some way. Well hope i helped, best of luck

Start by verifying the oil pressure sending unit. It is quite common for a bad sensor to act erratically, such as you have described. Acquire an oil pressure gauge and install it in an appropriate location, perhaps in place of the oil sending unit if a more convenient location is not available, and run the engine. Observe the pressure on the test gauge at various RPM and over a period of several minutes as the engine warms. If pressure on the gauge is good, then you have a problem either with the oil pressure sending unit, in the circuitry, or instrument panel gauge. However, the problem is most likely the sending unit. Note: the sending unit often requires a special socket, which may be obtained at any auto parts store. Also, if you don't own a test gauge or unwilling to purchase, many auto parts stores now rent tools, others even loan tools provided an adequate security deposit is made.

Testimonial: "Very happy with results, Replaced oil filter and now no issues."
