I have a question about my Nissan rb25det. It starts good when the engine is cold. But when the engine is hot. It cranks but won't start. Here is what I've done so far.
-I have changed all my spark plugs.still no help.
-When my engine is cold, I turn my key I can hear the pump is on (because there is a noise from the fuel pump)even I switch my fan on to level 3 I can still hear the noise from the pump.
-When hot engine, car is off. I've tried to turn my car on. I can hear the pump if my fan is off or in level 1. If I turn my fan on to level 3 and then turn on my car, then I cannot hear the pump. I have to turn the fan off and then try to crank my car. But still it won't start when engine is hot.
- Put starting fluid in to intake manifold. success. it starts when Hot!!. But if I turn off the engine and try again. It won't. I have to put starting fluid again. I don't want to try too many times with this starting fluid. Because it's harmful to my engine.
My conclusion is the fuel pump might be bad, fuel filter maybe?. Any other method to do more diagnosis. I really want to fix this part, and I fixed all mechanical of the ride.
Please let me know, if there are any solution. Would be much appreciated.
