I would go with the ones autozone gave to you.then I would check the coil packs for those 2 cylinders and see if that's the problem. If that ain't the problem then I would check the crank sensor

    If the camshafts were broke. I would do a compression. Check on all the cylinder. And see what they read.it could have bent valves or the piston rings could be wore

To review - - do you know for a fact the distributor is firing that cylinder? And do you have power and a ground pulse for that injector ?
You say no vac leak, but have you done a compression test on all cylinders ? Is it possible the egr valve is leaking and affecting that cylinder ?

ENGINE MISFIRE

There are few possibilities that can cause engine misfire issues. It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

03 ponitac grand am would not start 2 different times, it starts about 10 minutes later, it rolls over but doesn't start. Maybe a fuel pump or crank sensor I don't know any ideas?


Failure-to-start scenarios are often an issue of "fuel or spark?"

To check fuel pump, install a fuel pressure gauge on the Shrader valve connector on the
fuel rail, reading ???? - I couldn't find the spec for nominal fuel pressure.....

One good source of diagnostic info is your car's computer - commect an OBD-II code
reader to your car's OBD-II port and ask the car what it thinks it wrong - its capable of
posting 100s of possible error codes, any number of which would/could implicate a fuel
system component. Here a (very) short list of possible computer codes your car's computer
may currently be posting:

error code meaning
--------------- -------------
P0107 MAP (manifold absolute pressure) sensor - low input (to computer)
P0108 MAP (manifold absolute pressure) sensor - high input (to computer)
P0122 TP (throttle position) sensor - low input (to computer)
P0123 TP (throttle position) sensor - high input (to computer)
P0171 fuel system lean
P0172 fuel system rich
P0201 fuel injector 1 control circuit malfunction
P0202 fuel injector 2 control circuit malfunction
P0203 fuel injector 3 control circuit malfunction
P0204 fuel injector 4 control circuit malfunction
P0300 multiple engine misfire detected
P0301 cylinder 1 misfire detected
P0302 cylinder 2 misfire detected
P0303 cylinder 3 misfire detected
P0304 cylinder 4 misfire detected
P0336 CPS (crankshaft position sensor) range/performance
P06xx control module (computer) failure

Error P0300 random/multiple cylinder misfire detected


Because of the way it is set up with the coils, if one cylinder misfires it affects another one. Also, if a plug or plug wire is bad it will do the same thing. But it is possible that the head gasket is bad because you said it was low on coolant. That will also cause a misfire. Check plugs to see if any of them are wet.
