SOURCE: 1997 gmc suburban 5.7L will not start. it has fire and 40 psi fuel pressure

40 psi on a 5.7 vortec isn't enough. It's way too low. You need between 55 and 65 psi to run right. To be certain, you could spray starter fluid into the intake and if it starts, fuel is your problem and replace the pump or filter. A lot of times its the filter so keep that in mind too.

1996 suburban with 5.7l have good fuel pressure, sparks at the plugs, cranks with starter fluid but wont crank when i disconnect the crank sensor.

when you say good fuel pressure is it 55 psi with the key on and engine off? any thing less then 50 psi will not start the engine. if the engine starts with starter fluid then the problem is in the fuel system.

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.
