I have a problem with a 88 Coupe 2.5/5 speed that I picked up a while back and put back on the road. After replacing the headgasket and doing a tune up on the car(plug/wires/fuel filter/ect) the car was running great. I started driving it to work and when I went to lunch Friday it decided to just die on me. I was turning into a parking lot and took the corner somewhat hard. When I did this the car just died without any warning, sputtering, ect. I tried to crank it back up but it would just turn over and not fire off. I checked for spark/fuel and both of them are present and look to be good. The car will not start on its own but it I hit it with carb cleaner, it will start up but then die. If I pump the gas rapidly then it will stay running but very very rough. Today when looking at it, I had it running and I unplugged the MAP senor and the car would run better but was still not driveable and a little rough. I unpugged the vacum line from the MAP and didnt really notice a differnace at how the car ran. I am going to swap out the MAP tomorrow and see what happens. I was hearing a continous electrical noise when driving the car,which sounds like the fuel pump(if the tank was empty) but can hear it when the tank it full also. I dont hear tht now so I think maybe the fuel pump might be going down hill but havent taken the pressure from it yet. Any ideas?

The car is in a parking lot by work and this is my weekend to work so I can only work on it at lunch and a little after work. Might end up towing it home but hope to drive it home.

From your description it does sound like the pump. Or a split hose off the pump in the tank. Definitely need to get a pressure tester on it. Kind of difficult without the TBI pressure test adapter but doable. I used a standard fuel pressure test gauge with some hoses clamped on the lines with the fuel filter removed.

Here is a pic of the TBI pressure test adapter I was talking about:

Well you answered my next question on how to check the fuel pressure on a the car. Will change out some parts tomorrow during lunch at work and see what happens. Even though I dont wanna think about it, I am sure its the pump went south being I think its the original pump. And the fact that it was louder that it should have been and I knew it was going to be a issue, just didnt think it would happen this fast.

Looked up the price of the TBI adapter--$64------Will use your method of testing for pressure!!

Hudini where did you get the TBI tester? an how much are they?

i take it that its not the '88 you got off of me as you said the pump was original you thought. if it is my wifes old work car, you do remember the fuel pump story i told you right?

No this is an 88 Coupe that I got out of Houston about a month ago that had a blown head gasket. After troubleshooting it down, it is going to need a new fuel pump to get it back on the road. A friend is going to bring the car to his house and I am going to change the pump out.

Well I got the car back on the road and running good. The end problem was a hole was blown in the tube between the pump and the metal supply line. I went ahead and replaced the pump/strainer with a new A/C Delco pump so I want have to worry about that issue again.
