Engine cranks, won't start. Three days later, it starts???
2000 Jimmy wouldn't start. Disconnected fuel line at the fuel filter, no gas when engine turned over. Sought prices and planned to pull gas tank next weekend to replace the fuel pump. During the planning stage, and three days later, it started. There was nothing done to the car in the interim. Fuel guage sending unit stopped working 6 months ago. I know it is part of the fuel pump assembly, but can a fuel pump just start working? Side question, where is the fuel pump fuse?

still won't crank ? how's your battery ? starter ? starter solonoid ? if your engine does'nt crank , its dead ! would'nt you check the battery first ? then move on with checking the starter circuit ? seems like your putting the cart before the horse ! first of all, when you run out of gas, you need to replace the FUEL FILTER, your engine just sucked the dirt, garbage, etc., out of the tank. there's plenty of sediment in the tank, don't know how it gets there, but, you'd be surprized ! talking threw experience !!! I operate heavy equipment, its a cardinal sin to run out of fuel !!! you say you replaced the inline filter, which one, up by the engine or the main filter, under vehicle along frame ? are we talking about the same animal, PLEASE CLARIFY !
Disconnect your fuel line from the Fuel tank, take off the fuel filter and allow it to drain. Renew fuel filter and fill filter cup with diesel. Open line going to the injectors from the filter cup and allow to drain. Turn on the ignition while the line is disconnected and allow the pump to flow clearing any residual gas, do not crank the engine. With the fuel line disconnected from the injector, remove the glow plug relay. Crank the engine several times for 10-15 seconds at a time to cycle the fuel through without spark. Re-connect the fuel lines and replace the relay. Make sure that you have primed your fuel system as if you had ran out of fuel which by this point it already should be. Start the engine and run for 5 seconds, shut off, repeat this start cycle several times and you should be good.
You will have to pinpoint what the engine is missing... - Spark - Fuel - Compression
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 engine 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. Be extremely careful when doing these tests.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
That sounds like the fuel pump may have lost it's prime. Does it have fuel injection, or a carburetor on the engine? How much gas was in the tank while it was parked on an incline? Have you tried any starting fluid sprayed into the air intake hose, toward the engine? Warning! Don't use much starting fluid! Perhaps a one or two second burst, and have someone crank it immediately after you have stepped back at least 6 feet from the engine. If it fires, then it is definitely a fuel delivery problem! But it won't run long like that unless the fuel pump starts working again ... which is most likely when the engine is cold!
If the engine is turning, but slow, she may need the battery terminals cleaned, if it has sat for over a year, yes, it may need a new battery. If the engine is turning over and she is not cranking up. Standard rules apply... does she have fuel? does she have spark, does she have compression? First thing is easy, get a can of starting fluid and give her a spray in the air filter area during cranking, if she pops off you have spark, which means no fuel. If it does not try to hit, that means no spark and more trouble shooting will need to be done. If it starts on starting fluid, you may have a bad fuel pump. AS gas turns to gunk as it dries up. And that may have gummed up the pump and filter. Hope this helps FixYa up.
could be a number of things......engines need spark fuell and air to run.....one of three in your case is not working correctly
try disconnecting fuel line from engine side of feul sending unit and turn over ....get a bucket it could get messy....if you see fuel then check spark...to check spark leave fuel disconnected....and pull out one plugs leave wire on plug and touch plug threads to ground (anyground..eg..alternator bracket)use vice grips but not too tight ..then turn it over again and see if plug sparks......if spark and fuel are present ....then ur into crank sensors or cam sensors these determine when spark is present.....
when it does not start put fuel gauge onto injector line see if you have 32-40psi with key on and cranking then check for spark it also would be good to have a scan tool with data to see if crank signal is present
