Could be crankshaft position sensor problem . The engine computer energizes the fuel pump relay for two seconds to prime the fuel lines , injectors etc... With no crank sensor input to the PCM/ECM - ( engine computer ) while turning the engine over , the PCM/ECM will not energize the fuel pump relay . There are videos on youtube for testing crankshaft position sensors .

Truck start up run great couple minutes then shut off let set few minutes then crank up run great 30 second shuts down like you cut key off let set few minutes crank right back run fine then dose same


Sounds like it is running out of fuel. Maybe a bad fuel pump, or clogged filter. If it is carbureted, a stuck float valve or clogged float valve might be the problem.

Telling us year, make and model would allow us to help you more.

I have a 1994 chevy s-10 pick-up. I just replaced the gas tank, sending unit and fuel pump. Still won't start Prior to doing this I tried to drive it last week. It started and ran for about 2 minutes and...


Check the distributor cap and rotor.... If they look originial or if there's any moisture inside the cap, replace both of them.
Make sure that if you do replace them that theres no moisture in the distributor before putting new parts in.

Its cold and engine will crank but wont start, could the fuel pump went out ?


It could be the fuel pump, but try the battery first, it is less expensive and if that's not the problem you can normally take it back. Then maybe try tune-up if you have not had one recently. These are least expensive options as opposed to replacing a fuel pump.

Location and difficulty of replacing crank sensor on 92 park avenue? auto stalls out, farts, back fires? replaced water pump hose connecter that screws into block from top of water pump outlet? took out...


This could be one of many issues (or more than one!). When you say runs for 5 minutes, does it just stall? overheats? Probably not the crank sensor since when they go they go and engine will not run. If you can get it to Autozone or borow a diagnostic tool may be able to find an avenue to persue. My first thought is fuel from what you describe, fuel filter, fuel pump, injectors.

2000 Blazer Will not stay running


Wow, you seemed to have changed what I would have recommended to someone in your shoes.

If the fuel pump relay is hot, I think that there could be a crossed wire somewhere.

I would take it to an auto electric shop to diagnose problem if it's worth putting more money into it.

Intermittent starts


I assume the engine is cranking, but just not starting.

With the ignition ON, does the fuel pump run in this condition? If not, look for electrical issues with the fuel pump. If it does run, check to be sure you have proper fuel pressure.

1997 Jeep Grand Cherokee cranks but won't start


Same thing happened to me at about 140k. It was the fuel pump. Best way to test if your pump is failing and loosing pressure is to see if the car will start immediately after it has been running, or turn the key to the alt position for a few minutes before starting. If your engine fires faster after it has been running or the key has been in the alt position you will probably need a new fuel pump. Great news is with a very deep socket to get the tank straps off its a 30 minute job to replace the pump/filter assembly.

I have a 1993 Ford Probe GT. As I was driving, the engine suddenly died without warning. It wouldn't start again. After waiting a few minutes, it did start. Now I have only been able to get it started...


Yes a fuel filter can cause the problem but I would say it's most likely the fuel pump or fuel pump relay. Can you hear the fuel pump running when you turn on the ignition?
