Fuel problem/EFI

Where is the Fuel Pick up located in the tank? , If it at the back of the tank and you are going down a steep hill, that is probably the problem.

Hmmm, you havent got water in the tank ?

Although water would do it all the time when the tank was low not just down hill.

I have picked up water from some out the back servo's a few times during my travels, when the tank gets low it the car starts to miss, surg, pop and bang :-)

A bottle of metho cleans it up in one eazy go :-)

Brian. The amount of fuel in the tank may be simply a coincidence ar a red herring. The throttle position sensor adjustment is very sensitive, and even if slightly out will cause surging as it trys to switch the ECU from an idle measssage to part throttle. The publication states that this adjustment is not to be touched (factory set), but I had success with my own 96' courier and two others that I worked on. The method of adjustment I used was to rotate the TPS until the rpm rose (part throttle signal) then rotate the oposite direction until the rpm falls to idle plus a little more. Check by making sure that the engine changes smoothly from idle throghto mid range throttle without any sudden jumps, especially just off idle. Hope this helps.............col

It is possible that when the pump was replaced,the fuel guage sender was bent slightly and your fuel is well less than 1/4 .If the swirl pot is working ok it should keep enough fuel around the pickup until you are just about out of fuel.goodluck.
