Bogging Down with some work done, Gas Tank Fuel Pump?

[sandskms3]

Hello all,

I am new to the RangerStation and wanted to see if anyone had any suggestions. So here's the summarized question, just bought an 88 ranger 2.3L 4 cylinder. I've replaced the rail pump, fuel filter, ran codes and replaced the TPC sensor. It's main problem is that it loses power when it chooses in different gears and will then pick back up to normal power. It started to run better after replacing the tpc sensor, but now idles around 1000 rpms and will die on me when getting into first unless i give it a lot of power. Can't find a vacuum leak either. Is replacing the fuel pump in the gas tank a lot of work, and would that even be a cause? Anyone have any other ideas or know of similar problems, I would really appreciate it!

Also, it used to idle at high and low rpms as it chose, but now idles better after replacing tpc sensor, although it now drops below 1000 when putting into gear, it almost dies on my every time.

Sorry, I know I said condensed, but trust me, that is.

This can be caused by a few things...the fuel pump is usually a pretty cut and dried shut down though, so I'd look first at your other sensors.

Did you pull any code or not? That would be my first suggestion because it may point you directly to the problem...if you don't want to go that route it can be quite a bit of trial and error and cost you a bundle if you buy new replacement parts...

But if you're into a bit of experimenting and have a nearby junkyard...I'd suggest swapping out first the MAP sensor and then the inertia switch (get a couple of each if possible)

The MAP is under the hood by the firewall...the inertia switch is under the dash by the heater box usually...

These are both easy to swap and inexpensive at the junkyards...but try to get the codes....there are a few threads on code reading so if you're not familiar with that just do a search on the site and you should get a few hits that will help...
