Need Help With Mercruiser 5.0l Engine 1999

What does it mean when the engine is seized?

Engine seizure is normally the result of a failure of the lubrication system. It is often where a piston has friction welded itself to the cylinder bore. Sometimes it will be the big end bearing , the main bearings or the small end bearing. The net result is the same, though. The engine cannot be rotated. If you are very lucky, and the siezure is only slight, then the engine may free up again when it cools down. But damage will still have been done. Until water cooling and special oils were developed, racing two stroke engines were notorious for piston siezures.

Need help with Mercruiser 5.0L engine 1999?

I have a 1999 Mercruiser 5.0L 305 2 barrel carburetor that wont run smoothly.

I set the timing to 8 degrees in the base timing mode and it ran fine. But when i put some load on it in water it would feel like it didn't have power and was backfiring.

I then stopped the boat and quickly set the timing to about 30 degrees and it ran almost perfect under load.

Is the carburetor bad? Do i have to play around with the air fuel mixture while the boat is at 8 degrees timing? Or is there another problem that i dont know about?

Thank you for any advice in advance.

Does the 1989 Mercury Grand Marquis have the same engine as the Mustang 5.0 from the same era?

To add to brian9040's answer, the two engines have different firing orders. The Mustang 5.0L H.O. engine uses the 1-3-7-2-6-5-4-8 firing order instead the Grand Marquis's 1-5-4-2-6-3-7-8 firing order. The reason for this is because the Ford engineers didn't want to put too much stress on the front of the crankshaft caused by having cylinder #5 firing right after cylinder #1. Also, with the exception of California spec models, the Mustang 5.0L H.O. V8 began using mass airflow sensors in the 1989, up to its final year in 1993. The Mercury Grand Marquis, along with its Lincoln Town Car and Ford Crown Victoria twins, have never used a mass airflow induction systems all the way up to its demise in 1991. With that said, the cylinder heads are different as well as the camshaft and the EEC-IV processor that controls either application. Hope this helps.

The engine in my 1999 Ford Ranger is locked up.. what other engines can I put in it?

I have a 1999 Ford Ranger 3.0L v6 Flex Fuel and the motor is blown. I was wondering what engines I could use to replace it? I was thinking about swapping it with a 2002 Ford Ranger 3.0L engine but am unsure if it will work and if I would have to change anything else in my truck (i.e. wiring harness, computer, etc. etc.).

Would a 5.0L mustang engine fit in a 2002 ford explorer?

It probably would fit, BUT it would require A LOT of fabrication and rewiring for the electronic controls etc. Plus, I don't think it would pass emissions requirements once all is said and done due to the fact that a 5.0L is not as efficient and clean running as a 4.6L.

Check Engine Light / Grand Marquis?

i think the evap system (gas cap) is not monitored on a obd 1 car. or most of them so it wouldn't be a fuel cap.
maybe since the tune up was just done, the spark plug wires could be misfiring. just enough to cause the lite, you may not be able to feel the misfire. if you pull out 1 of the plug wire and the portion of the wire that is in the head is hard(ceramic i think) there was some problems with those.
if the light is on and off intermittent, then i would suspect an oxygen sensor. which one, i don't know. generally better to replace in pairs. it is the 4.6L, right?
an analog volt meter can be use to check codes also. any more details and i can give more advice.


no, not a fuel cap
it would not be the catalytic converter because it is not monitored on an obd 1 car.
i love master 'mechanics' for 30 years.

Why does the gas pump keep stopping when my tank isn’t full?

Question: “Why does the gas pump keep stopping when my tank is not full?”I have owned and worked on and built high performance engines since the 1960’s.Although it is possible that your car’s filler tube is damaged and restricted, that would have been caused either by an accident or by the removal and improper re-installation of the gas tank. If so, you would be aware of the problem, and it is unlikely you would be asking the question on Quora.The more likely explanation is that the vapor recovery system on the car is damaged.This system vents the fuel vapors from the fuel tank into a canister filled with absorbent granulated charcoal and then into the engine intake manifold, preventing the gases from venting off into to air and adding to pollution. (Older cars did vent gas fumes directly into the atmosphere. That is why you can smell raw gas at any display of classic cars.)In a modern car, if these fumes are not vented off, pressure will build up as you try to fill your gas tank, especially if you are doing so quickly. When the pump nozzle assembly senses this increased pressure it registers it as a full or nearly full tank and shuts off the flow of the gasoline from the pump to the nozzle. Think of that like trying to quickly fill a Coke bottle with water from a quickly flowing kitchen faucet. The air in the bottle has to escape before the liquid can go in.There are several points where the Evaporative Emissions Control System on your car could fail and create the problem you are experiencing. Vacuum lines might have been pinched or damaged. The solenoid valve may be sticking. But the most likely problem is that you have a clogged or damaged EVAP Canister.Your EVAP Canister looks like this,or like this.It is located in the engine compartment, low in the chassis, probably at the front.Why did the Evaporative Emissions Canister fail? Well, you broke it. Or someone else who fuels the car broke it.Did you ever continue to add gas to the tank, in an effort to add another gallon, after the nozzle clicks off? Well, in doing so you flooded the EVAP Canister by forcing liquid gasoline up lines that were meant to handle vapors. You saturated the charcoal media within the EVAP canister and prevented it from acting as a vapor recovery/transfer media.Your fueling problem can be resolved by replacing the EVAP Canister. Unfortunately, these things can be expensive.
