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.
I did your process with the ignition key, the three step process... and the car started like you said, but during the process the lock light on the dash would go off after a few seconds not ten minutes that you said, it did start after the third process backed out of the driveway about thirty feet, drove forward and it died again, it had no crank, had lights, dash lights, everything just know crank..
no the light is not on. you turn the key on to start it and i get nothing.If i turn the key on and try to start the car i get lights,dash lights,everything,just no crank.ithas done this before and like i said i could run through the gears and mess with the locks in no order and i could get it started.This morning it started after sitting all night and then died messed around and it started.then died after going about 30 feet.Then i did the sequence you told me to do and to my surprise it started. then the same it died and wouldnt start (no crank) lights and all but no crank. When i did the sequenc you told me you said the lock light would go off in about 10 minutes.That light goes off after a few seconds of releasing the key.
