i would say it may have a weak or bad fuel pump...sometimes you can bang on the fuel tank and it can wake up a dead fuel pump.

here is the basic no start test procedure

We will have to pinpoint what the engine is missing.





All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the car to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should! Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition.

the fuel rail has fuel in it. i had a check engine light awile ago and it said something about fuel pump. but it went away. so it might be the fuel pump?
Expert:  john -aka eauto replied 7 years ago.
i would think so i would check fuel pressure at the rail with a gauge and check injector pulse
