What is the fuel pressure under a load? try disconnecting the MAF sensor if the fuel press is ok, if the MAF is bad the engine will run better.

I have a 95 GMC suburban and my husband was on his way home and it died on him. it has gas in it and tries to turn over but wont start. what could it be?


What your going to have to do is have the fuel pressure checked.The pressure has to be 9-13 psi.If you have the 5.7 engine.If it is a 7.4 then it has to be 26-32 psi.If you don`t have a pressure tester then try tapping on the bottom of the fuel tank and if it starts then replace the fuel pump.If this is good then check for spark at the spark plugs.Let me know what you find.Good luck.
