\015 ''My flooded car starts but wontstay running after replacing engine'': My son drove my 2002Pontiac Gran Am into a flooded street. the car died and was hauledout with water inside to just a couple of inches below the frontseats. Abn experienced independent mechanic (with no electricalknowledge) rebuilt the 2.4L engine and drained the transmission towhere the car starts but wont stay running after a few seconds. I amnot sure what or how much troubleshooting he and an electrical buddyhave done (Starter, computer, ignition switch,fuel pump?) but the carhas been in the shop for three months now. I just lost my job anddesperatedly need to have it fixed even it takes me to tyroubleshootit with guidance from you all. I will really appreciatte any ideasand previous experience with flooded gran ams. Thanks. \015 Posted / edited by AnonymousUser on : 20-09-2021

Answers :

Just spitballing here but sounds like contaminated fuel or a block in the fuel line and or pump. Here's a link with a diagram for locating and checking the fuel line and best of luck to you.
Has the gas tank been drained and let to dry out and then refilled with gas and a water dryer and the fuel filter replaced? If not then you are in for trouble still and this is why is will not run. You are getting fuel and spark. Which means that your fuel pump is working and the starter is fine. Ingnition could be your problem but I would do the gas thing first then move on
