Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Do you have any trouble codes stored in the system?
Are you getting any unusual engine noise?
Unless you have a ton of engine noise, the symptoms you describe sounds like a restricted exhaust system. You might try disconnecting the exhaust at the manifold and see if the engine will run. If it does, then you know the problem is a restriction in either the catalytic converters or the muffler.
Be aware, it will be very loud with the exhaust disconnected.
Please let me know if you need additional info.
