Question about Chevrolet Silverado

1 Answer

My truck will turn over but will not fire up.

I am thinking the distributor cap but I am not sure how to pin point that I have replaced just about everything on the distributor and there is still no spark. I've checked all the fuses too. What else could it be?

Depending on your year it could be that your crankshaft positioning sensor has gone out. This is what regulates your spark. For older years, If you have changed out the whole distibutor then you can follow that by changing your plugs and wires as well. To best test this you can take one of you spark plug wires off the spark plug itself and either use a specific light the you plug into the wire or you can use a screw driver being very careful where you place it. If you are getting spark through the wires then you may not have the right gap on your spark plugs or they may be bad. If you don't get spark it deals with your wires or distributor. Best way is to buy new ones and that will fix the problem.

I am working on a 1993toyota Corolla 1.8 no fire changed whole distributed assembly tested power coming to coil it's good still no spark checked all fuses there ok any sugestions

if the coil is tested fully and is good where have you checked for it being good? have you checked if the HT lead from the coil to the distributor is carrying power? If you have power at the distributor cap , all the contacts are good, the rotor is fine, (check current at the distributor cap centre pin) then the likely problem is the machanism for firing, i.e. Hall sensor . I would check all the HT leads, distributor cap, rotor etc. you should carry out the checks systematically. I.E. First check at the coil with a multi meter. Then check at the end of the Ht lead from coil to distributor , actually within the lead itself , for current. then attach it to distributor if it shows a current...if you are getting a current from the distributors centre pin the issue is probably the cap itself, the rotor arm, the firing system, it will probably be electronic as mechanical distributors went out some years before I think. or if that is okay, the leads themselves. I would guess that is is distributor cap or firing system related'

My distributor on 94 gmc 1500 5.7 I replace but didn't mark rotor the distributor falls in n the teeth line up together rotor points between 6 n 8 o clock what will happen if its not the rite way

if its off when you go to start will backfire.if your not sure pull number 1 spark plug and then turn engine with bolt on crankshaft put finger over #1 spark plug hole when you feel air slow down and use flash light to see piston coming up when its all the way up stop then put cap on distributor and see where number one wire is mark distributor and then with rotor on stab distrib with rotor pointing at number one your mark you put on distrib housing then put cap back on and should fire right up if it still back fires your 180 drees off meaning when #1 piston was coming up it was on exhuast instead of compression so take cap off see where your pointing good luck its really not that bad

94 Isuzu Rodeo 2.6L. I replaced head gasket and now the motor will turn but no start. I did not mess with timing during procedure but did replace rotor and dist cap while it was out. Also tried to replace...

remove the distributor cap and check inner part of the cap there should be a black pin (Carbon Look) in the center of the cap, if you only have a hole, the pin fell of and without it the spark won't jump from the coil to the spark plugs. If it fell, take the old cap, and take out that pin and put it on the new one.

How do i know my firing order is right first do i make sure my # one plug is up first

Yes. Bring number 1 piston to top dead center of the compression stroke. Remove the distributor cap and see which post on the cap the rotor button is pointing to. This is where the number 1 plug wire goes. Follow your firing order on the cap in the same direction the distributor turns and your firing order will be right.

I rebuilt the 350 but now can't get it to start everything is new I don't think i'm getting fire to the spark plugs. the distributor is new and I think I have it installed right.I have gas to the carb. it...

I think you need to re-time the ignition--remove #1 spark plug (front plug on driver's side), place a ratchet and socket on the crankshaft bolt, stick your finger just into the plug hole, and turn the engine CW through until you feel pressure building in the cylinder. At that point, remove your finger and watch the degree marks come up on the crankshaft pulley or vibration damper as you turn slowly. When the idle firing point aligns, stop turning. Open the distributor so that you can watch either the points just start opening or the reluctor tooth just enters the stator match point while you rotate the distributor body. Tighten the distributor clamp lightly. Check that the rotor is pointing at #1 plug wire. If not, shift the wiring in the cap around until it does while maintaining firing order. The engine should run at that point. Use a timing light to get it right on later. Tighten the distributor when everything is right. Hope this gets you running!

95 dodge caravan with no start problem.

Connect a timing light to the number one plug wire and crank the engine. Does the light flash indicating that the Number one is firing? Look at the distributor. If you have a distributor cap and rotor assembly remove the distributor cap and crank the engine. If the rotor turns check the rotor to make sure there is a good contact point and check the distributor cap to ensure there are good contacts. If either is damaged or worn replace them both. If the rotor does not turn you have a broken timing belt or one of the timing belt/chain guides has jammed and the engine needs to be rebuilt.

Intake manifold gasket

make sure the #1 cylinder is at top dead center then make sure the rotor in the distributor is pointing at the # 1 spark plug wire on the distributor cap............if you have already done this you have the timing 180 degrees out and you need to point the rotor 1 half turn(exactly opposite the #1 spark plug wire on the distributor cap)

With the timming marks lined up make sure that cylinder 1 is at top dead center on the compresion stroke, then as you lower the distributer back in make sure that the rotor is pointing to the number 1 plug wire post on the distributor cap,mark the distributor where the #1 post is since you can't install it with the cap on.
