So, I'm going on the on ramp to I 70 today after leaving school. I drop it into second and try to get up to speed and the engine feels like its missing. It like bogs down, doesnt speed up, shaking from engine . Going through town its fine, but 3,000+ rpm it misses pretty bad. I go home turn it off. Drive it up to 80mph an hour ago and no problems.
So my mechanic does a "fuel pressure" test or something like that. It reads 40lbs at idle. He said its supposed to be a minimum of 48 lbs. He says fuel pump is weak and will be 680 to replace it.
The car now drives fine, idles fine, and revs without any problem. The problem is obviously on and off. So is this definately a fuel pump? Also, is there a place to get a cheaper fuel pump that will work in a 97 3.8? The one from napa is the "whole sending unit" which he claims it HAS to have. And its like 300 dollars. I read the articles about the trap door method, and figured Id save a HUGE amount of money by doing it myself. Does it sound like a fuel pump for sure? Anyone use the trap door method here? And do I need the whole assembly or just a pump?
