Most chevy 5.3 do not use a cap and rotor. Most have single coil per spark plug and wire. Trace spark plug wires to coil usually above the valve cover.

A diagram may not be needed as its a reasonably easy fix to do on your own.the distributor ca p will only fit on properly one way because at the base of the cap locaters can only fit the distributor if they line up.When doing the spark plug leads do them one at a time and if nessecary write or mark leads as 1,2 etc .The rotor can only fit on one way but put a mark on the distributor to show where the rotor was pointing when you took it off and if it still points there when the new one is fitted.When changing distributor cap and leads they have to go to the correct place.Pays to mark the outside of distributor cap where the locating bits are On the new and old one.Fit the new cap and rotor then take a spark plug lead and fit to new cap 1 at a time.You can tell by lining up the marks on the outside of the distributor cap when you hold them one on top of the other.Good luck

SOURCE: spark after i changed distributor cap but wont start

sounds like you haven't indexed the rotor correctly or the cap isn't seated correctly.  Did you replace the plug wires correctly?  Dis you bump the position of the distributor?

Como cambiar distribuidor gmc safari 2001


Remove the distributor cap. Mark the location where the rotor is pointing by making a scratch mark on the distributor housing. Remove the distributor adjusting bolt and bracket. Remove the distributor. Replace with the new distributor by placing the rotor on the shaft and turning the shaft until the rotor aligns with the same place as the mark on the old one. Install the bolt and tighten. Start engine. If your engine does not run, remove the bolt and distributor and turn it 180 degrees and replace.

How to replace distributor


remove the air cleaner and mark where the plug wires are on the distributor cap. if you get lost the firing order on the v8 is 1-8-4-3-6-5-7-2 remove the distributor cap. unplug the distributor and using a white grease marker mark where the tab on the rotor is pointing. i usually make sure its where i can mark the intake so i can line it up later. go to the parts store and either rent or buy a distributor tool to remove the bolt holding the lock down clip at the base of the distributor. dont let it fall Murphy law says it will fall where you cant get a hold of it lol. after removing the lock down clip the get a hold of the distributor and wiggle it back and forth while pulling up on it it should slide out. when you reinstall it make sure you line it up with tab and your mark. as you put it down in it slides into the tooth of the cam and will rotate as you slide it in so you have to be one tooth before your mark and it should slide into the mark. make sure you use the new gasket with the new one and dont over tighten the lock down bolt. good luck

    I believe those motors have a distributorless ignition system. Each cylinder has a coil mounted on top of the valve cover.

    GMC 2500 P/U 350 Vortec.. Installed rebuilt engine,engine turns over, coil will spark one time and we get no more fire.


    Have you checked to see if your distributor is aligned properly? I just had to change out a distributor on a 1997 GMC 3/4 ton that has the V8 Vortec in it as well and you need to pay attention to the (2) numbers around the mating surface / rim of the distributor. You should see a number 8 and a number 6. You need to find TDC on your number 1 cyl. You can either slowly crank the motor over or turn the motor over with a ratchet and socket on the bolt securing the main pully to the crank while another person places their finger over the spark plug hole and when it just starts to Stop pushing air out past your finger then stop. Is the rotor aligned with the number what ever size engine you have in your truck (i.e. 6 or 8)? If not then your timing is off. You will need to remove the distributor and rotor, then install your rotor (before re-installing the distributor) and align the rotor pointer with either the number 8 or 6 stamped on the lip of the distributor where the cap sits down and creates the seal. I have found that they run both numbers on the distributor because they use the same distributor in both the V6 and V8 Vortec motors or a least the plastic base of the distributor. There will be (2) numbers here and sometimes hard to see. Align the pointer with what size engine you have and lower the distributor down into the hole. If the end of the shaft starts to turn the rotor as it aligns with the oil pump causing the pointer to no longer be pointed at the number that indicates which engine this is being installed in then you need to remove the distributor and look down into the hole where the distributor goes in and you'll see the end of the oil pump shaft with a slot (perfect for a big flat head screwdriver) staring back up at you. You'll need to insert a long shanked large flat head screwdriver down into the hole and turn the slotted oil pump shaft until you can successfully lower the distrubutor into place and not lose your mark. I also found that you'll need to have to pointer of the rotor a bit retarted from where it is suppose to be. This is because the distributor shaft gear is swirled and will cause the rotor to turn as it finds its mark, aligns and lowers down into a seated position. When it is seated and the rotor has stopped turning it should be pointing at the indicated cylinder Stamp in the lip that is your size motor (V6 or V8). Now it should be on time. The computer will take care of advancing and retarding.

    If not the timing, then I would also consider that you may have a bad crank shaft sensor. These are merley suggestions because there is no more to go on than what you've submitted.
