Replace the crank position sensor, or at least clean the old one, any metal particles on the sensor will cause it to read and send the wrong informtion to the engine management systems. Hope that helps, Mikey

96 olds lss had fuel pump replaced wont stay started long sputter spits ect.


You better find a different mechanic . Before calling a bad fuel pump ,did he do fuel pressure test ? Did he test the electrical circuit ? Did he check mass air flow sensor ,injectors , fuel regulator , engine senors ? How many miles on the vehicle , is the engine in good shape ? Timing chain ?

2000 ford explore, wont start. if I prime it, it starts right up and stays running fine. shut it off and it wont start again.


I'd go through, and first check the fuses that go back to the fuel pump, and make sure it is making contact before you have to go chasing ghosts. If that doesn't work, then you might try checking your fuel pressure: prime it, run the engine for a few minutes, then kill it: watch to see if the pressure drops off pretty quick after the fuel pump is off. I'm betting on a ground at the fuel pump, though: the simple act of the vibrating running engine usually provides a decent connection.

73 gmc dump stops running after 10 miles. any thoughts?


Check your carburator to see if it has a "last chance" filter installed behind the fuel inlet nipple. Also check to see if your fuel line is running too close to hot parts of the engine or exhaust... if the fuel boils in the line, it will vapor lock the fuel system and kill the engine.

2000 1500 Sierra will not stay running step on gas act like its running out of gas. Popped top fuel line gas came poured outbut didn't pump out when i rolled the engine over. Got underneath the fuel cell...


Replace the fuel pump and fuel filter to correct the problem you are having. Without the proper fuel pressure the engine will not run at all. Hope this will help you. You might check the fuse/relay panel for a blown fuse or relay in it to make sure you are getting power to fuel pump before you go to the trouble of removing the pump and fuel filter. Hope this will help you.

I have a cadallic escadale. It will turn over but wont start.


The fuel pressure should be 60 to 65psi in your system with the engine not running and fuel line primed, (ignition key's to the run position). Once engine is running the fuel pressure should drop by 5psi, change the fuel filter and recheck the fuel pressure at the shredder valve. it's known for the fuel pump to fail when the gas tank runs low or out of gas, the pump will end up burning it self out since the gas is what keeps the electric fuel pump cooled. The other thing to is putting gas through the top of the throttle body to start the engine on the SEFI is a NO NO, well a BIG NO NO. it's been know for the gas in the intake to catch fire and burn up the poppet valve in the injection system causing the replacement of the fuel injection system. Keep me posted and good luck, be gald to help you get your truck running again for the july 4th. OH and it was not mentioned but did the fuel filter get replaced???

Ran out of gas wont start now


if its petrol engine bang bottom of fuel tank while some one else cranks vehicle over if it starts good just pump jammed if it dont buzz to life and you cant hear fuel pump buzzing ceck for power to it if thats there replace pump. running out of fuel kills electric fuel pumps internally in petrol tanks.

if its diesel you must bleed fuel system taking extreme care if you un do lines some very high pressure

Runs ruff and kills while driving


Might want try a new fuel filter, could be plugging up. If thats not an issue, you should do a fuel pressure test. Fuel pump could be getting weak, or getting ready to go out all together.

Car wont start


Does the engine sound different when it cranks? It might be a timing belt concern? Remove the oil cap and look for the camshaft.(you might need a flashlight).Have a partner crank the engine and watch the cam. If it stays still you have a bad timing belt.Let me know what you find.
