Well, Saturday and yesterday I worked on it again. I checked my fuel pressure with my engine off: 39 psi With my engine running: 31psi and it retained its pressure just fine. Well after I did that I, changed my wires and then pulled my codes, I was getting a code 172 and 173 (running rich and running lean) so I figgured that maybe my Oxygen sensor was bad or messing up so I changed it. So far so good, it hasn't messed up again (but it didn't mess up every time before either).
Before I changed the oxygen sensor I also got the codes: 225 and 542.
Well, now I need to pull my starter and have it rebuilt; and I have a heater coolant line that needs replaced. Well, I hope that it is fixed, I guess I will find out. Thanks all for all of the help.
- Frank
