I have a 90 230 sea ray with a 99 7.4L MPI bravo 1
I have been working on this for a while. when running it will only run for a short time once it gets up to running temp 160 ish it starts cutting out (not always immediately). if I sit for a while it will start and run.
It also will only run about 3200rpm I have a 17P vengance on it right now. I have been changing out my fuel filter because it has set for so long. it has had quite a bit of crap in them. I am going to pull the tank and clean it. I also tested the fuel pressure it is between 32 and 35 PSI. in the manual it says it should be at 43.
My question is
1) while cleaning the tank is there anything else I should look for or clean while pulling this?
2) Is the low pressure a sign that the fuel pump is going out?
2a) With the low fuel pressure can that cause my other symptoms?
2b) what would cause it to bounce in pressure?
any help or ideas would be great. Thanks
