Ihave fuel problems, I've put on new fuel filter fuel pump'and new fuel pump relay and it still won't start any suggestions? It starts when you put gas in the intake but when it's gone it quits again.

Hello,

Check the fuel pressure make sure you are getting fuel.
You could have a clogged line somewhere which can prevent the fuel from getting to the engine, even though you have good pump and filter. You could have a bad fuel pressure regulator.

You should have 60-66 PSI of fuel pressure with the key On and engine Off.

Here is how to check the fuel pressure:

If you do not have correct fuel pressure check the fuel pressure regulator.

I have attached diagrams for your reference.

Please let me know of any questions.

Thank you.
