Truck: 98 sonoma, 2.2l with 5 speed.
Till the waterpump incident recently, no issues but a hard start every once in a while.
My fuel pressure is a solid 38psi while running and it seems to generally hold when turned off but sometimes it seems to not build the pressure quickly wuen starting. Like i have to crank it for a bit and give it some pedal to get it to finally spin the engine up fast enough it starts.
Its not an all the time deal, just enough that i know it will happen once a day if i take the truck more than one place.
Sound like the check valve at the pump? The regulator seems to be working amd the fuel system will solidly hold 38 to 40psi if i let it sit for 5 minutes. Its sitting right now and still holding so i will watch it for a bit.
Oddly, this morning it started and seemed to be firing on only 3 cylinders. I attribute all these problems to the damn waterpump overheat incident from last week.
Also, what is the weird pipe the thermostat housing connects to? Its leaking, is why i ask. Right whete the pipe goes into the thermostat housing so you smell coolant and can see it weeping and dribbling when running. I am going to look on rockauto to see if they have it but i don't know what its called.
I am attempting to put up pics but they are always sideway.
Edit. After 10 minutes, pressure is at 36psi
