Fuel pump failing or fuel filter blockage possibly starving engine. Also, check all vacuum lines for cracks or disconnects.

93 toyota pickup 4x4 it will stay running after I turn it on to start it up, it starts up then after a few seconds it kills


if I'm reading this right...
... the engine starts and dies within a few seconds.
... you jumpered the fuel pump test connector and it will keep running.
... you smell fuel after trying to re-start when it dies.

Disconnect the plug to the cold start injector. Even if you have an issue with the engine running then dying after a few seconds after doing this, if you don't smell fuel after disconnecting the cold start injector and try to restart it, the cold start time injector time switch may be failing.

Buy a can of starting fluid and have someone start the engine then spray short bursts of the fluid around all the intake fittings. If spraying the fluid in any particular area keeps the engine running, I'd start looking for leaks around that area.


It does sound like an AFM or COR issue considering it dies after a few seconds, but the fuel smell when trying to restart the engine may be a separate issue that needs corrected / isolated first.it will keep running.

Car Surges then dies at a stop only in hot or warm weather


Think about what you just said. Only does this in times of higher temps out BUT never in winters cold. Doesn't that seem strange to you. Well I guess it does, huh. Anyway, know these systems helps. When engine is started, the temp sensor tells the computer it needs to place the engine to cold start mode. It does this and extra fuel is put into the cylinders to keep it running like a choke on the carbureted engines. But those you can turn the choke off or it does this automatically from the warmer engine. If in fact the temp sensor is not telling the computer it's warm enough to be taken out of cold start mode, it keeps dumping excessive fuel into the cylinders an flooding the engine causing it to surge and then die, because it's flooded. Therefore, the temperature sensor is faulty and needs replaced. Do that and drive on.

Fan doesn't run while in idle and begins to over heat until I start driving agin then it cools back down to normal. Also the fan runs when engine is off and drains the battery.


The fan is only supposed to come on when there is excess heat .. in normal driving conditions it doesn't start. When you start your car in the morning the fan won't come on because the engine is cold.

With a hot engine - and it depends how hot the engine is - the fan will only kick in to prevent overheating. In heavy slow moving traffic or a traffic jam, the fan will kick in if needed.

The air flow through the radiator is usually sufficient -in normal driving conditions - to cool the engine.

When you park up and the car has a hot engine, the fan will kick in. This is perfectly normal. It is caused by a surge of hot coolant triggering the fan sensor. Perfectly normal.

The fan then should cut out after a while .. maybe 2-3 minutes at the most. If the fan runs continuously that suggests a fault in the temperature sensor switch.

Next time - wait by the car and see how long it takes for the fan to quit after you have parked up. It should stop of its own accord after a couple of minutes.

If the fan cuts off after a short while, and your battery is becoming drained, that's probably a battery or alternator fault.

Remember: when you start the car the fan won't kick in at idle speed because the engine is COLD, and there is no reason for the fan to start up ..
The fan WILL kick in for a couple of minutes after you have parked the vehicle and the engine is hot

Dies after running about 2 minutes


It's got all the symptoms of a leak in the fuel line. You may want to start backward at the tank and work your way all the way to the carb to find it but it would be surprising if it was something else. All the best.

Surges,dies when slow down,starts and runs for a minute


I wasn't able to read the rest of your sentence, from what I see it sounds like the fuel filter or a plugged up fuel line. I hope this helps, good luck!

Idle fluctuates


Its could be a few things. Most likely cause is you IAC (Idle air control valve) If this valve gets clogged up with carbon it will cause a idle surge on cold starts like you are describing.

Next your FITV (fast idle thermal valve). When the hot wax inside of this valve starts to wear it will cause a idle surge on cold starts.

You might want to start by replacing the crank sensor first.
