Has cap and rotor been replaced and then this started? if so you have a faulty cap or rotor. you should not have to file down fins to keep from hitting. the distributor could have wear allowing it to lift enough to hit if so it will need to be replaced or rebuilt. the filing down idea is just trying to cover up a problem and not correctly fix the issue

How do I get a 4.3 back in time after removing distributor?

If you got the distributor in at least close to where it originally was, leave it in for now. You will have to find TDC for #1 cylinder by turning crankshaft until you see and line up timing marks. When you line up the timing marks, you will be on for #1 or 180 degrees off. You will able to tell by pulling the cap and seeing if it's pointing at #1(or near it). When you're sure you are lined up TDC on #1, pull the distributor, noting how much the rotor turns counterclockwise(CCW) when pulling dist out. Now hold the dist housing in the position you want it to sit in the block( determined by where #1 spark terminal will be), the rotor should be CCW about 1 1/2" from the #1 term, then lower dist housing down while watching the rotor turn clockwise and line up with the #1 spark plug terminal. The dist housing will be flush with block if done correctly. It takes some practice, but as long as you get #1 lined up at the crank timing tab and don't disturb it, you can play with the dist all day. The trick is, you have to get the oil pump shaft lined up with the drive tang on the bottom of the dist. You can use a long flat blade screwdriver to turn the oil pump shaft to the right clock position so it lines up when you drop in the dist. Remember to hold dist housing steady when lowering and let rotor turn into position. Good luck.

1978 ford f250 351/400 dies when put in drive

Turn in the idle speed screw on the carburetor throttle-raise the idle some, it will open the throttle plate a bit when you turn the screw in. Idle speed should be about 800 rpm's, with truck in drive, foot on brake, and engine at normal operating temperature. If it still dies with the idle raised, it might need a tune-up-plugs, wires, dist. cap and rotor, and new filters. Good luck.

1997 nissan quest camshaft sensor where is it & how to replace it

The camshaft sensor is located inside the distributor and is part of it, in order to replace it you must replace the distributor,to replace remove the dist cap. mark the location of the rotor,by marking where its pointing to, then mark the dist housing, so now theres a mark on the rotor and housing to show where rotor points, next mark the location of dist going into housing, mark the shaft and the block,because it spins in block this way you can line back remove hold down bolt and pull out,mark the new dist in exacat same spots as the old so you can install back the same,you may have to put it in and pull it out until your marks are lined up,this way the timing will be dead on, when done you can check timing. good luck

1997 chevy c 10 truck wont start and back firing just put in new distributor It died this morning had to be towed home what is wrong ???

You should begin by static timing it. Mark #1 location at distributor on engine or something you can refer to later. Remove Dist. cap make sure the distributor rotor is rotating when engine cranks, If it does not the timing chain broke. If it rotates:
1. pull #1 plug, place thumb over plug hole and rotate balancer with socket wrench till it blows your finger off hole. This is #1 TDC compression stroke.
2. look at distributor rotor--it should be pointing at #1 location mark you made earlier if it is you have a spark issue.
3. If it is not pointing to #1 you remove Dist. hold down bolt under Dist. and carefully pull the dist. up while rotating rotor.
4. You will need to advance the dist. a few teeth past#1 (rotating Rotor) then re-install dist. if it doesn't line up to #1 keep repeating step 4 till it does. After you get it right you should be good to go. A timing gun will be needed after to clock in the timing after installing the distributor.
Good luck!!!

1990 K5 Blazer DIED(Electrical?)?

There may be no injector pulse if the computor does not see a RPM signal.
There will be no spark if the ignition module does not see a dist pulse from the dist pickup.......a RPM signal.
Because you do not have both ......I would suggest to check/change the dist pick up.
Follow the wires from the ignition module inside the dist to the pickup which is also inside the dist.
If it is just a bad dist pickup....keep all your old parts as good spares. the dist turning? to provide a RPM signal?
You will have to remove the dist to change the pick-up.....mark your timing locations......"rotor position" and "dist body location"before removal.
A quick test before installing the "repaired dist" .....plug it in the the truck wiring and turn on the key....DO NOT CRANK THE ENGINE OR YOU WILL LOSE YOUR DIST ROTOR CORRECT you spin the dist by hand .....the injectors should spray.
