88' tbi fuel problems

Hey guys
I just recently purchased this truck from a farmer that had let it sit for a couple years. little by little ive been fixing the odds and ends on it.

Im having problems with one of my fuel pumps (driver side). When I just fire it up and the truck is cold it will idle on the pump. Once I put any throttle on it, it will want to die on me. Then when the truck is warm it wont run on it at all. The passenger side tank runs fine so i just use that one. Any thoughts? Now ive tried looking for the fuel filter and i cant find it. I see the passenger filter just on the passenger rear door. Should it be in the same location? I thought about the oil presure scensor but if that was the problem then neither tank would work. right? Also both tanks read up to half full. When it gets to empty i just fill up again fearing that i will run out. But it only takes 13 gallons so i know theres still gas in there.
any help would be great. i know a pump will run me about $300. so im just trying to rule out all posabilitys before i get one..

thanks

The pump shouldnt be that much unless you are having a repair shop install it. It does sound like the pump in giving up on you. the filter you see is for both tanks.

Oh I see, so that would rule out the fuel filter. You are right i found a pump for 180 at my local part store. My thoughts were that the senders were bad in the tanks as well because of the guage reading half full neven when its all the way full. But now im thinking its the gauge it self. Or is this a commen problem? Does anybody know what amps the senders send to the guage when the tank is full? I can check it but just dont know what im looking for.

thanks for the reply

If you ground the wire for the guage, it should make the guage go to full. Ungrounded it will go to empty

I had problems with my '89 similar to this. It wouldn't run most of the time and had low fuel pressure. It ended up being the the tank selector switch on the dash. my truck also sat for a few years and the terminals inside the switch had corroded which was causing both pumps to run at once but neither were putting out enough pressure.

Holy christ man $180 for a new pump on a TBI application? That pump should be about $75 MAXIMUM, for a name brand like AC Delco or Delphi. Look it up somewhere else.

Granted I get a shop discount which helps but isn't really a huge help unless the price of the part is pretty high to begin with. I put a Airtex fuel pump in my 88 TBI 454 and it runs great. The pump and strainer sock from orielly's cost me $39.XX for the both of them. Something is wrong when I can change both pumps and both strainers for $100 less than you were quoted for one pump. IMHO you need to look somewhere other than where you are looking before you purchase. Just my $.02.
