Okay and did you add all 6 directly to the engine or to the underhood reservoir?

Thanks.

Can you check the underhood reservoir and see how much oil is in it? It should be filled to the Full/2 quart line.

Also, is the engine cranking and not firing I suspect?

When you turn the key, does the engine rotate and not start, or no engine rotation at all?

Is there anything else that happened during the oil change that would be worth noting?
Customer: replied 6 years ago.
no just that , yes the engine rotate and no start
Expert:  Doug replied 6 years ago.
Hm.

Is the oil level light on on the dashboard?
Customer: replied 6 years ago.
no
Customer: replied 6 years ago.
what else can l do
Expert:  Doug replied 6 years ago.
Well, if you are certain there is nothing else you might have unhooked, etc, and both oil levels are correct after the oil change, we are going to need to diagnose like normal.

The first thing we need to do is see if you have spark at your spark plugs.

To access the sparkplugs you need to remove the passenger seat and the metal floorpan to access the cylinder head, remove the plug wire cover and pull out one plug wire and spark plug.
Insert the spark plug into the plug wire and clamp the plug to a good chassis ground and observe it while cranking to see if you have spark.
If you have a spare plug wire and plug laying around, you can access the distributor from under the vehicle and just replace one of the plug wire leads with your spare one and proceed.

Find out if you have spark and we'll go from there.

yes l have spark

Thanks,

Can you check the fuel pulse by placing a noid light or meter across one of the injector connectors?
