You can have another problem instead of the fuel flow. If you have no "check engine" light, the free places like Autozone, Oreilys, or Advance will not find anything. It takes a better computer to test your car or you need to do it manually.

You can certainly flood the motor with gas through constant cranking or by having one or more bad fuel injectors. The Injectors leak down the pressure because one or more fail to close. In this case a mechanic would attach a pressure gauge to the test tap on the fuel rail. You would leave the gauge attached after taking the PSI pressure reading and writing it down.

Then after a few hours or overnight you would reread the gauges to see if there was a pressure drop. If there was a drop, look at the sparkplugs for wetness from the dripping gas. With dripping gas, you will need to change the oil as it has been thinned by the gas.

Many times the problem is in the "Cold Start" circuit, which reports a cold temperature to the computer to reset the engine. If the sensor for the cold start does not work, the engine stays in its lean running mode and is hard to start. There are often 2 water sensors, but only 1 of them operates the cold start circuit, the other operates the dash gauge.

The air sensor in the intake snorkel will also set up the engine for cold starts and this sensor is usually in the air intake before the air filter.

I hope what I have said is very useful to you. You did not include the Brand of car or truck this question is about. If my answer does not help, then include a Brand and model with a new request.

2006 nissan altima wont start when hot. Like not


I assume it starts and runs fine when cold? It could be a faulty TPS. Since the TPS adjust the setting of the throttle (butterfly plate) inside the throttle body. If the throttle body is dirty it will give you satarting/running problems. Make sure its nice and clean. Then see what happens. If problem persists after cleaning I would suspect the TPS is bad.

No spark 99 forester


Disconnect the fuel line from the filter and check if there is fuel when you prime it. If there is NOT fuel, you have a lead. If there IS fuel coming out, it might not be enough pressure. I had to replace an O-ring on the fuel pump assembly. Hope I helped.

Pt wont start good battery,satarter good


Is the starter spinning? If it is spinning is the selonid(bendix) engaging? That is to say is the engine turning over? If so my next thought would be the ignition module which is located inside the distributor on the bottom.(black box). All the above is providing the engine is getting fuel.
