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!!

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.
