Working on a 1988 Ford F-150 heavy duty with a 302 engine and 4X4 truck. We have replaced the following parts on it, EGR Valve, Map Sencer, desatiber and the electronic ignision under the cap. We have also replace Oil pressure sending unit, the brain, and a few other sencers on the truck. Now what it is doing is, weather it is cold or hot now, it acts like it is starving for fuel and dies. We are stuck and can't figure it out. We have put $1,100 into it the last 3 months. Anyone have any ideas on what it might be or anything like that? PLEASE help me before I go push it off a cliff LOL... My cell number is 406-291-0887 need to get it fixed A.S.A.P.

 

Checked the fuel pressure yet? Replace the fuel filter if you haven't already.That shouldn't cost too much.If pressure is still low it could be the pump. Throwing parts at these things without a starting point can get expensive quick.
