1996 GMC Suburban will not start.

I have a 96 suburban.5.7 Vortex. I have good spark, fuel pressure, and compression. I replaced everything I can think of. Timing is dead center. Computer diagnose shows no rpm reading.

I have a 96 GMC Suburban that turns over with spark at the coil but has no spark at the plugs. I have replaced the coil and the ICM. What else could it be?


Hi and welcome to FixYa!

Have you replaced the distributor coil pack? If the coil pack is burnt or worn out there will be no spark to the plugs which may result to a no start issue. I strongly suggest that you have it replaced.

Hope this helps and thank you for using FixYa! Have a good one!

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.

1996 Suburban, after changing the Fule Pump Module with another module, I turn the key over and hear a whirr from the tank but the vehicle will not start. i think the Fuel Pump Module must be bad, but do...


The fuel pump module may not be bad. If you hear whirr that is good. Did you change both of the filters, the one on the fuel pump and the external filter (the one along the frame of the trunk). Also did you clean out the tank? If you did all that the next step would most likly point to fuel injectors.

and the throttle position sensor, also have a fuel pressure test done, especially for the hesitation.

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.
