I'm going to assume you can tell by listening that the cylinders still have normal compression.
There is a cam sensor which uses the camshaft and an ignition module that together provide the ground to the coil. Either component could have failed.
Since you changed the cam and the timing chain it could be something related to the cam sensor.
You may need to get a book or shop manual to have the test procedures for each component.

Purchase a timing light and check your engine time against the front pulley and the timing scale located around your timing chain cover. If you have recently had your timing belt or chain replaced you could be a tooth off.
With regard to your ABS light the easiest thing to check or replace is the speed sensor on the wheel. Because this is a magnetic pick-up sensor and due to the location (on the wheel behind the rotor) can be susceptible to corrosion. That is also the most common cause of an illuminated ABS light. Do you have 4 or 2 wheel anti lock? The 4 wheel abs doesn't change what could be wrong, it just means you have more speed sensors to check.

Do a compresion check, if Ok then timing chain is ok, try some throtle body cleaner trough a vac. hose while cranking if stars, fuel pump is out, another way if you have no codes the most poss. cuase is your fuel pump, check press is gauge handy

I have replaced the head gasket on my 2000 sephia. Had the head surfaced and valves seated and checked, after haveing all that done i get it put back togather and all the wireing checked, now it wont start...

No fire at the plugs means no power to the coil/coils or the coil/coils are bad. You say it won't start, I'll take that it does crank over and won't fire. You have to have power from the switch to the coil, coil to distributor, and cranking sends fire to plugs. With a test light, check that there IS power from the switch and ongoing. This is a must do.

How do you check the coil packs

Pull plug wire off and put new plug in the wire and then ground the plug against something metal like the alternator, or the block and have someone crank it over and watch for spark.
But that may not prove the coil is bad because something like a crank sensor tells the coil when to fire. Probably a little over your head with out the proper tools to do this operation.

I replaced head gaskets on 1997 suburban 5.7 tried to start no fire to plugs pulled coil wire off no sign of spark took photos before and everything is hooked up right was running before but was missing...

There are a few things to look at first take a good look at the distributor, there are connections to the module, one goes to coil and the other from wiring harness make sure all conections are connected, check the coil connection too, next is theres a few ground wires to thermostat housing, this is a main computer ground, most of the time its grounded to bolt on housing if not look around for it and make sure its grounded, these are the most common reasons, also all power wires connected on alt and at the starter, make sure no wires were pulled out by mistake.

check the plug wires to make sure there in the right firing order then i would recheck the timing once again the roter can be just a little off and you should be able to get it started if that dont work i would check the timing chain.

We changed the intake gasket and now the Jimmy won't fire,

Get #1cylinder up to TDC (at timing marks on pulley) on compression stroke, and your distributor rotor should be pointing at the plug wire tab on cap for #1 .
