it sounds to me that your truck jumped time which means you could have a bad timing chain it also depends on how many miles the truck has and has it ever been replaced b-4 but i would say you need to replace the timing chain.
The oil pressure switch is located at the back of the engine next to the distributor. Looking at it from the front of truck it will be right of distributor. Normally it can be changed without removing the distributor.
Not without modification. Two very different platforms.
Not without modification as 2000 is the newer body style which was implemented in 1999.
It is built into the distributor and is not available without buying a distributor.
Pick up coil?
The crank sensor is not in the distributor, it is in the top of the bell housing. The cam position sensor is in the distributor and is not available separately
Without this, your distributor won't work. Without your distributor... :( Go to your distributor. On the outside of it you should see a plug with harness (?) feeding into the distributor. This is the beginning of your pickup coil "assembly". Take off your distributor cap. You'll see that "harness"/assembly feeds into the very top of your distributor, held by a "molded" grommet (on mine), then, it "coils" around the top and you'll see that it feeds (or plugs into) into some part of the distributor (again, you can only see this when your distributor cap is off). I'm basing all of this on my 84 CJ7. I have no clue if all distributors are the same. Good luck.
Most of the time it breaks off and you will need to drill it out and replace screew.
YES.
If you have made the mistake of removing the distributor from an engine without marking exactly where the rotor was, and where the distributor was, you have created a lot of work for yourself. First, you must get the crankshaft to Top Dead Center for the number one piston. There are timing marks on the pulley, which must line up with a pointer or mark mounted on the block. Once this is done, the distributor must be inserted into the head in such a way that the rotor will be under the number one cylinder plug wire position when the distributor is seated. This usually means having the rotor about 20 degrees offset when inserting the distributor, to allow for the worm gear to line up with the drive gear. Then, you have to turn the distributor until the lobe on the distributor shaft which opens the points is just beginning to open the points. Once this is done, the engine should start, and then will need to be timed with a timing light.
Car and distributor would have to be replaced
to get it right without turning on a check engine light you need a scan tool to set the distributor right otherwise "cam timing" will be off. if you have a scan tool then you remove the cap and mark where your rotor is pointing then you remove the clamp bolt with a 9/16 wrench or socket. place clamp and bolt out of way, then unplug the connectors and then remove distributor by pulling up and out. install is the reverse of removal. be sure that your distributor seats all the way down before bolting it down. if not seated then raise it slightly and turn rotor one tooth and set down again. when it drops down all the way be sure its not pointing 180 degrees from where the old one was. if it is raise it out again and turn 180. is will only drop in two ways. if no scan tool you can move it around until it runs enough to get you to a shop that can set the timing.
