Crank but no start

It sounds like you have a blown head gasket between two cylinders but to be sure we need to do a compression test. If you don't have a gauge you can rent one for free at the local auto parts store.

Please let us know what you find.

Nice work, are all cylinders low or just two or? I want to make sure the head gasket will fix it, if all cylinders are low then it could be the timing chain/belt.

Please let me know

Yep the head needs to come off I would check the valves while the head is off. Here are some diagrams to help you get started.

Have the head resurfaced before reinstalling it.

Here is the instructions by the book.

Release the fuel pressure.
Drain engine coolant. Be careful not to spill coolant on drive belts.
Release the fuel pressure. Refer to Powertrain Management; Fuel Delivery and Air Induction.
Remove the air duct to intake manifold collector.
Remove the engine drive belts.
Remove the front splash undercovers.
Remove the front exhaust tube.
Before removing the intake manifold collector from the engine, the following parts should be disconnected to remove the intake manifold collector:
EGR tube
Fuel injector connectors
Ground harness
Breather pipe Harness connectors for:
IACV-AAC valve
Throttle position sensor
Throttle position switch
EGR temperature sensor
Water hoses from collector
Heater hoses
PCV hose Vacuum hoses for:
EVAP canister
Power brake booster
Fuel pressure regulator
Remove the intake manifold rear supports.
Remove the exhaust manifold.
Remove the ignition coils.
Remove the spark plugs.
Remove the rocker cover bolts in numerical order as shown.
Set No. 1 piston at TDC on its compression stroke.
Rotate crankshaft until mating mark on camshaft sprocket is set at position indicated in figure.
Remove camshaft position sensor (PHASE).
Do not allow any magnetic materials to contact the camshaft position sensor (PHASE).
Be careful not to damage sensor.
Remove intake valve timing control solenoid.
Remove cylinder head front cover.
Remove timing chain guide from camshaft bracket.
Attach a suitable stopper pin to chain tensioner.
Remove chain tensioner.
Remove camshaft sprocket bolts.
Apply paint to timing chain and cam sprockets for alignment during installation.
Remove camshaft sprockets.
Remove camshaft brackets and camshafts.
Apply I.D. marks to brackets to ensure correct reassembly.
Bolts should be loosened in two or three steps.
Remove cylinder head bolts.
Remove cylinder head with intake manifold.
Head warping or cracking could result from removing in incorrect order.
Cylinder head bolts should be loosened in two or three steps.

You will need to change the oil when you are done.
