Car is turning over but wont start seems like gas problem


Listen for the 2 second hum or buzz from the gas tank, when you turn the key to on, not start. The pump should run for about 2 seconds to put pressure in the lines and up to the fuel rail. If you don't hear it, first check the fuel pump fuse, usually in the under hood fuse/relay center. Or you could check for fuel pressure at the testing port-shrader valve- on the fuel rail. If you punch the center valve down with a small screwdriver, gas should try to spurt out. If no pressure, the pump is bad or the wiring to it needs to be investigated. Power flows from the battery to the fuse to the fuel pump relay and then to the gas tank. The relay is turned on by the pcm and allows the relay to pass power on to the pump.

Many parts stores rent or loan fuel pressure gauges to check your fuel pressure. The correct pressure is critical for the injectors to work right. If the car won't start, check fuel pressure and check for spark. Usually gas or spark is the problem.

Volvo engine wont start


Sounds like it's the pump. Did you turn the key (to on position) with the rear seat removed, and listen for the pump (when key is just turned to on / 2nd position without starting) . You should hear the pump make some fluid exchange / pump noise...

My 96 volvo 850 gtl2.4L ENGINE CRANK OVER BUT WONT START I REPLACED THE INGNITION COIL \ POWER STAGE WITH NO RESULTS.PLEASE HELP


Reasons for engine turning over and not firing are simple. Spark or fuel. If you've changed the coil packs then chances are it's a fuel issue. Get in cab and turn ignition to second position whilst listening to back seat. You should hear the faint noise of the fuel pump working. If you can't, I suggest you firstly check your manual to find the fuse/relay for the fuel pump and check that. If they are fine, you need to replace fuel pump.

If you can hear it working and it still won't start, remove the fuel line going to injector rail and point into a jar whilst someone turns engine over. You should have fuel coming out. If this is fine, go back to ignition, remove a spark plug and turn engine over checking for a spark.

My bet is your fuel pump has packed-up. Good luck diagnosing.

98 chevy 2500 wont start after cutting off while i was driving


Turn the key to the on (not run) position and listen tosee if you could hear the fuel pump turn on (prime) for a few seconds. If not, check the fuel pump fuse and if its good, its probably a bad fuel pump.

How did it die? Did it feel like you were out of gas?

1998 olds 88 wont start no power windows or seats


i don't have a solution but my car did the same thing in october 2009 and i still have not had it repaired. I am told it is something electrical because its your fuel pump is not coming on and that is why the car is not starting but it doesnt make since why the windows and power seats dont work. I have also been told the only thing that connects the 3 of them is the body control module.

I have a 1986 oldsmobile ciera. It started and ran just fine yesterday, and now it will turn over and has power but it wont start. Its almost as if it isnt getting any fuel.


1st check for spark at two different plug wires. then press the schraeder valve on the fuel rail and see if fuel runs out or trickles out. then use a test light at the fuel injector wire harness. unplug the connector and test for voltage on one side. then clamp to hot(positive) and check for blinking ground while cranking.Make sure fuses are good
