2001 tacoma v6 doesn't want to start when hot. I can start it by pressing the gas at the right time. The problem is that it cranks differently. not as hard and kind of "skips". give it a half hour or more to cool, and it turns over like it always has. Seems to be getting worse. I'm starting to have problems in the morning now as well. hard to explain, but it sounds and feels different. If it starts when hot without giving it gas, it idles low and rough for a few seconds and dies.

Check for fuel pressure when starting. Fuel pumps have a check valve in them that keep fuel in the rail at the injectors. If the check valve fails, the pump has to pump fuel all of the way up to the engine. Same thing with hot no-restarts. Fuel pump.

Check the timing and compression of the engine. It sounds like you either have a blown head gasket or a the timing jumped.

Hello

I just worked on this problem a couple of days ago. If the motor is a 3.0 liter. The idle control valve is located at the bottom of the throttlebody assembly right below the bore for the throttle butterflies..What usually causes this valve to go bad is the mechanical part of the sensor sticks as it becomes sludged or carboned up. Manufacturer claims that the valve cannot be cleaned and should only be replaced....It's a high dollar repair to replace this sensor as your engine coolant flows through this electrical valve. The valve idles the car fast when cold, as the antifreeze gets hot the valve drops the idle down.....I have successfully cleaned several of these valves and cured the dying problems...
First remove the air filter top cover and the tubes that connect to the throttlebody. In the right throttlebody you will see a port right before the butterfly. Under the throttlebody you have a black plastic sensor with a 2 wire terminal. Remove the 2 phillps screws and pull off the electrical part of the valve. you will feel a magnetic pull while removing. Remove slowly and catch the black sealing oring, and there will be a metal washer also.. The shaft that is exposed is the mechanical control of the valve. Rotate the shaft and it should feel sticky if bad..Using a throttlebody spray cleaner spray into the small square port of the right bore, rotate shaft and spray until stickfree.....Reassemble

Could be a oil pressure switch not letting the ignition fire because it doesn't detect enough pressure.

the fuel pump in my 99 4runner isnt getting power. I changed the fuel pump and the efi relay. the 20amp efi fuse doesnt have any power to it but the relay does have power. fuel pump wont turn on when turnin the key in the ignition. what could be the problem?
