Question about 1998 Ford F150 Regular Cab
I have a 1998 Ford F-150 4x4 (3rd dooris the suicide door) 5.4L, V-8. When I can get it started, it runs great....for a while, then all the guages will go flat and it dies. Most of the time, I can't get it restarted without jumping it. Once I do get it restarted, it can do it again at any time. It may take days, or it might do it right away. I replaced the battery on
April 30, then took that one back and replaced it last weekend, so I don't think it is that.
Please help. My other car has a blown head gasket, so I need this one to run.
A friend of mine jumped my 81 blazer with his dads 95 chevy truck and accidentally crossed the cables .... blew his computer up. The truck ran the same way you are explaining. You should be able to check everything by hooking it up to a computer at a local garage. Hope this was helpfull.

Most of the fords have a 100amp fuse that protects from crossing the battery.on the side of the under hood fuse box there should be a small cover pull it up and there will be a 2 inch fuse there.check it for power on both sides if it blew your alternator will not charge

Sounds like you've an old electrical system that is infact drawing too
much power due to either bad conections or some kind of short. First
thing I must wonder about is if you've done the cars positive, negative
, grounds, wire contacts and posts on the battery , the starter ,
alternator ,any plug in connectors , the main cars comp=ECM and the
other comp modules pins and jacks,all your cars sensors , the ingition
coil , replaced any of the smaller grounds that run under the hood to
chasis etc. One thing is these contacts are vital in any kind of car or
vehicle ,especially one as old as yours .Many people don't overhaul
these things and that causes constant problems , especially in the
winter months or extreme dampmess or heated times of the yr.
If I was were you I'd do this once a yr just before winter on any vehicle older then 5 yrs .I think your cars volt regulator is bad or ECM could have a built in voltage regulator thats gone bad or acting up or that theres a problem some place in that circuit that supplies or feeds or regulates the cars currents.
Try using a set of wire brushes and fine sandpaper on those contacts or areas I've mentioned and get them either very shiny or replace the connectors or ground wires. Don't worry about the connectors you may see as ground junctioning wires that go across the cars to ground different things if real rusted etc , just buy or make up new wires and connectors and make brand new fresh grounds. You can buy a special anti conductive anti moister jell thats great for not just spark plug wires but also for kind of sealing the different ground or chassis etc contacts or connections from dampness and moister by simply applying a bit of this stuff on it.I highly recommend if you like your vehicle and or need a more reliable vehicle that you do these things and also change oil every 2,000 kms , plus change fuel filters every yr and theres much more that should be done on a regular basis.
I get asked alot why I'm fixing my car or working on it alot , my reply is a car doesn't maintain itself. But who knows with modernization growing so rappidly, you never know maybe some day lmao.
Hope this helps you and good luck , don't hesitate to ask me more questions if you feel the need
