I'm new and I need helpppp :(
So I got the car about a month ago and it's a built lt1 p600b procharger kit, my problem is that yesterday I got caught it a heavy storm and after driving thru the rain the car won't boost and cuts out/back fires when I step on it and won't go over 4,000 rpm, so I believe the opti got wet and is going bad now? Although after the rain and these problems started I noticed that my fuel pressure is way lower than normal so could it just be the opti? Or plugs and fuel filter? I'm just so confused any help or advice would be awesome thanks

The fuel pump is a new walbro pump put in with the rebuild about 2000 miles ago so it shouldn't be that, Ill prob get a new filter no matter what and yeah it's bottom mount intercooler with the cold air intake down by the turn signal

Is your car a non vented or vented opti. Could still have some water lift in there if its non vented. Have you checked the fuel regulator, could also be as simple as a vacuum leak on the regulator.

With low fuel pressure the car generally would only run at high rpm, the in tank hose on my Walbro ripped and I only had 10psi of pressure and it would only run if I kept it over 4000 rpm. Your issue sounds more like the opti being wet, although you may have sucked water up into and through the pro charger and I don't know enough about them to know if that can hurt them. You can try letting it sit in the sun with the hood up for a few hours, or remove the waterpump and pull the opti cover and see if that dries it faster. The opti has 360 tiny holes representing 360 degrees of timing in a steel disk, if those holes get corroded or covered with water you can have your issues.
