Need firing order for z28 comro 5.7l - Camaro Chevrolet Cars & Trucks

First you must determine if the fuel is stopping or the spark is stopping..If the fuel is stopping this could be a computer problem.. If the spark is stopping then it could be the IGN Module in the distributer. or any nomber of sensors. Squirt a little fuel directly into the Throttle body on the intake manifold.. If the truck runs longer its probably loss of fuel.. Do this several times to make sure, be careful and only use a small amounty of fuel.. you do not want a fire.. RE: Spark: Take a plug wire and an old plug..put the wire on the plug.. hold the plug against a good ground .. have someone crank the engine .. does the plug stop firing? The engine dies.. and will not restart for a minuet or so.. during this "no start" time do the plug test. If the plug will not fire during this time take the module out and take it to Orillys Auto parts.. They can test it.. really expensive part. Don't replace until you know it is BAD..

1 8 4 3 6 5 7 2

how much feul pressure, it must maintain a certain amount if injected, or throtle body, try priming it ,and see if it helps, ( poor a little into inlet ) and check it , if it starts you need to check pump, or maybe just filter

The firing order is 1-8-4-3-6-5-7-2, this engine is equipped with an opti-spark distributor that is located behind the water pump and the crankshaft pulley.

18436572 if it's a v8. 1357 front to rear on drivers side, 2468 front to rear on pass side.

1-8-4-3-6-5-7-2

look on the intake or cylinder head it should be inscribed there.

Fuel pressure? Do you hear the fuel pump running? Read the codes to see if ECM is still alive. Do you have spark at the plugs? Remember all motors need 3 things to run air, fuel, and fire at the right time.

try changing the tach filter. Mine was located on the fire wall behind the distributor on a 1984 z28

it might be the optispark harness wire.it starts and runs good. once u turn it off its hard to turn back on?
