Engine starts runs briefly shuts off rattle

If immediately after an oil change it is definitely an overfill. They should fix the problem.

Can you send a pic of the dipstick level.
Car off.
Remove dipstick
Clean with paper towel
Reinsert dipstick
Remove and check level (take pic)

Empty extra oil.
Clean throttle body.
Sop up extra oil off inside top of engine under throttle body.
Clean MAF since you are there.

For spraying starter fluid, you can do it yourself. Spray. Jump in and press the power while foot is on the brake. Jump back out and additionally spray as needed.

 

I emptied out roughly 3/4 quart of oil so the dip stick reads below max. I cleaned the Tb. I changed the spark plugs. I managed to keep the car running as long as I keep spraying starter fuel. I bypassed the circuit opening relay and EFI relay with two paper clips, no luck. Now it's down to the fuel pump test... It could possibly also be the ecu, who knows..
