    Hello guys I am new on here but not new to the turbo buick world. Have owned a 1987 Buick Grand National for a while now and just purchased a 1987turbo t. When I bought it, it would sputter on but quickly turn off. Well I brought it home yeaterday and checked the fuse for it first before starting anything. I pulled out the fuse and checked the continuaty and it was good. Went to start it again and started put died and the fuel pump would not even make a priming noise same as before. Had a Walbro pump with a hot wire kit new and installed it. Still nothing. Connected the old fuel pump straight to the battery and it ran no issues. HMM :nope: So i decided to replace the fuse nothing as well still cant get the pump to run. I also changed the relay with the one from my grand national and still nothing. I changed the conputer out with the one from my grand national nothing. I checked the orange wire from the ECM going to battery and its connected. Also checked the Oil Pressure sensor to see if it was corroded or loose and its tight on the sensor. Also tried jumping the pump with the test jumper on the back of the alternator and nothing pump did not come on. My question is, is there anything else that I can try or check to see that is wrong?

    I would make sure you have a good ground. Make sure the plug is properly connected at the tank. Also provide power to the connector by the alternator and check for voltage at the plug. You can use this to help if you do not already have a wiring diagram.

    He said over on the mothership he has a hot wire kit. First thing to do is disconnect that I've seen them fail and kill power to the pump.

    That is true, you have to rule that out first.
