Prado Petrol 2004 Series 120 - Longer to start when hot

Starts perfectly first go in the morning. As soon as the engine warms up you need to wind the starter over many more times before it kicks, then runs perfectly. Had fuel pump and filter replaced in the last month due to dirty fuel. Another mechanic who now has the car in another city says the fuel pressure is dropping away when the motor is off the fuel pump 'O' rings are normally the issue, which he has checked and played with and didn't fix problem. My thoughts are if the fuel pump had an issue not holding pressure, how come the motor starts perfectly first thing in the morning. Mechanic here has suggestions around the fuel injectors leaking and the car is slightly flooded when trying to start, after it burns the fuel, the car starts. Reason it is okay in the morning is that the fuel in the chamber has evaporated. I like the theory. Problem car is in a another town and that mechanic says the fuel pressure is dropping immediately. Thanks

SOURCE: 95 Camaro Z-28 starts hard

could be alot of things but there are 3 basic principles/requirements for any gasoline engine to start. You need fuel, compression and ignition. Not much you can do about the compression short of having the engine rebuilt so focus on the other two. Fuel includes a good clean air supply (check air filter) and fresh gas (check and replace fuel filter). If the injectors have been already been cleaned, that's about all you can do. Have your spark plugs been replaced? Bad plugs will also cause this problem. The ignition system aslo consists of spark plug wires and other components that may need replacing. If this is beyond your mechanical capability, I'd have a mechanic connect the car to a scope to see if any of these systems are acting up.

sounds like it could be the relay. also this one has 2 pumps I think, one in the tank LP and one on the rail just under the driver. 2 relays also one for each.

Oil usage Huyndai Santa Fe 2002 (4 cylinder)


If its a petrol motor then they will blow a little white smoke/steam on startup until the exhaust heats up. The engines computer knows that its cold so richens the petrol/air mixture to warm it up faster . You should let it warm a little before driving off or if you can't then don't rev it hard til it starts to warm up. All the parts inside the engine need to get to optimal running temp to wear properly. Most engines wear more on startup then when they have been running for a long time. In regards to smoke blue is bad (oil) black is bad ( to much fuel) and white is usually on startup.
