First start any day is a nightmare. My 2000 toyota sienna hardly starts the first time i try to start. after going around, there is no problem starting. Any advice what is wrong?


Might be fuel pressure leakdown. Try turning the key to RUN for about 3-seconds, but not START. Then turn to OFF. Repeat 3 times and then try to start. If it starts, you have a bad check valve in the fuel pump that's allowing fuel pressure to drain down overnight. Replace fuel pump.

If that doesn't work, try depressing the gas pedal halfway while cranking the engine. If that helps, check out the engine coolant temp sensor. A sensor that's out of calibration will send bad info to the computer and the computer will provide too lean a mixture for a cold engine. Depressing the pedal overrides the sensor and the computer adds gas.

Hard starting when cold. 30 sec to min crank. Runs good after start.


Hi Thomas:
Sounds like it's not getting fuel right away.
I'd be checking the choke, and also perhaps try priming by pushing gas pedal all the way down twice, spin over 2 or 3 seconds, then pump gas pedal twice again, then try to start.
None of this is valid if it is a diesel.

1994 Chevy 3500hd 6.5 turbo diesel starts then stalls. I have to pump the gas pedal a lot before it starts again. Once started, it runs rough. Specially when I step on the pedal.


As there is no connection between the accelerator pedal and the fuel system then pumping the pedal will have no effect.. I would be checking and bleeding the fuel system from the filter to the pump and checking for a leak in the fuel supply system. Hard starting and running rough is an indication of air in the pump and in the lines to the injectors.

Ford ranger 1996 4.0L v6 single cab long bed it runs but you have 2 have your foot on the gas it does not stay in idle for more than 5min less than that usually it does not take much gas pedal pressure to...


I would suspect that you have a failing fuel pump, the fuel pump pressure is bleeding off due to a faulty check valve, this causes hard starting esp when cold or after sitting. The fuel pump is located inside the fuel tank, the fuel tank must be removed to replace the fuel pump assembly.

Hard cold start 1997 Jetta gas


can't say for sure but almost all engines that have come to me needing ether to cold start have poor compression. test the compression first.
you sould never need to use ether on a gas engine and very carefully on a diesel when very cold.

Fuel pump not running only in cold weather


Pumping the pedal on an injected engine does nothing, except varying the air intake amount. I would change the fuel filter (if badly plugged, it may be causing the pump to shut off early) and clean the idle air control valve.(which should regulate idle air flow, eliminating the need for playing with the pedal) The valve itself is not difficult to service, but is a bit delicate. It can be cleaned with carb cleaner. just make sure you do not turn the valve end around while cleaning, and re-install it perfectly straight. You may have a bad drain back valve in the pump, but this is less common than what I outlined above.(there are tests for this)
