Rear scubbing on my right rear brakes


If there is still a problem with your brakes take it back to the shop and they should look at it free. They should probably fix it too.

How to remove the pick-up coil from the distributor. 1989 GMC 1500 4X4


The distributor does have to be removed and dis-assembled in order to replace the ignition pick-up coil/stator, and if the pick-up coil/stator is faulty then the distributor should be replaced because the distributor will come with a new pick-up coil/stator and the old distributor will have to be removed anyway and in the long run it will actually save money from not having to pay a mechanic to remove and dis-assemble the distributor to replace the pick-up coil/stator, however most of the time it is the ignition module inside of the distributor that is faulty.




When the engine is at TDC (Top Dead Center) is the ignition rotor pointing to the #1 position on the distributor housing as described below?



The engine should be set on TDC (Top Dead Center) with the distributor cap removed, and there is a mark or notch on the distributor housing that the rotor should be pointing to when the engine is on top dead center. (Look under the distributor cap and find where the number one terminal runs under the distributor cap, and where that position on the distributor cap corresponds with the distributor housing, and it should match up to a mark or a notch on the distributor housing)

This static timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at top dead center.



If the engine is at TDC and the ignition rotor does not point to the #1 mark on the distributor housing, then loosen the hold down bolt to the distributor and turn the distributor until the rotor is pointing to the #1 mark on the distributor and then tighten the distributor hold down bolt.

1991 Nissan 2400 pick-up, rattling sound in moter with loss of power. Oil light came on but is full of oil. what could it be?


the oil light comes on from loss of oil pressure, this can be from two things 1. your oil pump is bad abd 2. your bearings around the crankshaft are bad. If the noise is coming from the bottom of the engine, Then the bearings are bad. If the noise is at the top then this could be the distributor. the distributor drives the oil pump, there is a shaft or a pin/tongue on the bottom of the distributor. See if it is broke. Also look down the hole and see if the pump is broke. It's hard to see but you can with a good light and mirror. Just a note, If your truck has had a knock for a while(like when you start it in the morningand it goes away in a few minutes or seconds) Then the bearings are bad. It's time to rebuild or replace.

My 1997 civic cut off while driveing and wont start back up it has very little spark when trying to crank ive changed the cap and rotor any could this maybe my coil


I had a 1995 civic that the distributor windings came apart inside I had to change the distributor $450.00 for the part. Its easy to see if that is the problem just take the distributor cap off and look inside for freyed wires.
You may be able to pick up a used one at a salvage yard.

Oil light came on. On Interstate and drove about 9 miles to next exit. Car died on exit ramp. Will not start. Oil was about 1.5 qts low. Filled it up, but still won't start. Is there some automatic shut...


Only 1.5 qts low would not shut the engine off. It sounds like your oil pressure sending unit needs to be replaced. If the Oil pressure sending unit reads less then 8 psi or thinks there is less then 8 psi the ECM will shut the engine off. It's a simple fix and the sending unit is on the drivers side behind the distributor on the engine block. You can pick one up from Auto Zone and they can give you the step by step instructions to replacing the unit. As long as there was no bad noises coming from the engine when it shut down, it should be a simple fix. If there was any bad noises coming from the engine, then your oil pump may have gone bad and will need to be replaced and hope nothing else has failed or have gotten damaged due to lack of oil pressure. Good luck and keep me posted.

1998 chevy K1500 timing runs ok for 10 miles then loses all pwr


1-timing on truck is ajusted by ecm,when u moved it u cause cam sensor code because it detected timing was off! 2-o2 sensors has the role of detecting air to fuel ratio coming out of exhaust,sends signal to ecm wich collects data from other sensors from that sets timing for best performance,if ecm detects something wrong in system data it will give engine code,that code will point at problem area,in your case o2 sensors probably detected lean fuel ratio that points to fuel system,blocked fuel filter or fuel pump faillure,elect,circuit damage,hope it helped!

NO You will have to replace distributor because the cranks sensor is located in distributor, However to help cut cost I would recommend getting a use distributor from a salvage place it should be alot less.
