So about a year ago I swapped the wore out 5.0 vortec to a 5.7 vortec crate motor from summit, it came as a long block but I reused my engine accessories such as alternator, ps pump, ac compressors and the intake although I replaced the spider assembly, my problem is about once or twice a month if I let my truck sit for more than 48 hours it won’t want to start, it seems to just be getting to much fuel??.. usually I can crank on it for a minute and it will start but after for sitting for 3 days it will low not start at all. The spark plugs are getting fouled out instantly. I’ve replaced the fuel pump, fuel filter, fuel pressure regulator. Spark plugs, distributor cap and the ignition coil! I don’t know what else it could be! It’s getting both spark and fuel!!
Any help would be greatly appreciated!
