Thread: 2008 Turns over but wont start!!

I would check fuel pressure with a gauge before buying a pump. Did you check for codes? Just because it starts with fuel being added does not mean the pump is bad. If somethimg is keeping the injectors from pulsing it will show the same symptom.

I agree. I was so surprised that he didn't have a gauge. I am actually going to a part store to rent a gauge and check it myself and finish the job. I refuse to buy a fuel pump until I know for sure if the pressure is right.

Since fuel pump assemblies are kinda expensive, I wonder if you could pull the pump and test it before the purchase. I guess you could just unhook the lines, pop a hose on the end leading to a bucket, right?

Yea that definitely is a good point. But I am going to put a gauge on the rails first as soon as I can find one for a reasonable price. Those things are expensive

Wow just what I've been looking for! Thanks bro!

still think its the fuel pump from what all thats been said

Simple way to check for fueling is to pull a plug after you've turned they key on and off a couple of times. Each time you do that, the injectors should prime the cylinders with a little fuel. Plugs would be wet quickly. Your mechanic's test of adding fuel and having it fire is good to conclude the cylinders aren't getting fuel. However with the key on and a multimeter set to voltage, look for 12v+ on one of the injector wires. Our injectors have voltage when the key is on and the pcm pulses ground to them. If you don't see power, then check the fuse.

Ok thanks I will try what you advised. But actually I do have a schrader valve on my fuel rail. The mechanic was pressing the valve stem to see if fuel would shoot out of it. Fuel did shoot out when pressed but it wasnt very much pressure.

Yep thats it. Wow nice pic bro

!!!!UPDATE: Took my car to have it diagnosed and it has been determined that my PCM needs to be reflashed. I have no idea what that means and the mechanic doesn't know why it happened. He said the fuel injectors are not getting fuel to them and its because the PCM is not working properly. He also told me that only the dealership can reflash the PCM. Does this sound legitimate???
