2001 gmc savana 1 ton check engine light flashing after replacing fuel pump

Changed the fuel pump and the air idle control valve, when I went to start it after this gas was pouring out of the tank, fixed that problem, but now when I start it, it runs very rough almost like a clanking noise heard mainly under the van. Also the check engine light is flashing. Any tips would be greatly appreciated!!

fuel pump sock or try the egr valve to see if it is stuck open all the time. can't remember if that one has the digital one and a vachumm type as well, next would be the evaperative canister purge valve.

look under the hood on the right side where your brake fluid is..There is a black box to the farest right of the brake fluid. take off the lid to this box were you will find fuses..Reach in and feel the fuses to see if any are loose.The largest fuses in the front, push down on those and then try to start it up..Take them out look at them make sure there ok if this dont work..they the one bad might need to be replaced..

2003 gmc savanna, wont start, new fuel pump and ignition cylinder, I turned key to on position, let sit for 15 min and still wont start just turns over

Find fuel test valve in fuel rail on top of engine. Take cap off valve. Turn key on. Push down valve with screw driver. fuel should squirt out. If not check fuse fuel pressure relay and bad wires. If fuel does come out, remove a spark plug from engine. Connect plug wire to plug. Ground plug against engine. Crank over engine and look for spark.

97 GMC Savana starts then chokes and stalls out.

Have you checked your fuel pressure.Sounds like you might have a weak fuel pump.Your fuel pressure should be 60-66 psi with the key on and engine off.This fuel system needs at least 52 psi to open the popit valve inside the injector to allow fuel thru.

Engine cranks excessively before engine starts,even after warmed

Check your EGR valve make sure that is working properly, if it is then go to the fuel pump, just a cheaper fix to go after the EGR then the fuel pump
