I am new to this forum and I am not really sure were to post this. I would like to know if anyone can help me? My wife has a 89 gp and that will not start (it starts for 5 seconds and the chugs to a halt, then you try to restart and it just grinds). I have changed the fuel filter, checked fuel pressure, and they are ok (40 psi as recommended by chilton's manual). I have sprayed some starting fluid in and does not do anything different. I tried a crank shaft sensor (the coil and module have been replaced recently). I have pulled the spark plugs and I have spark. I am not sure how to test the fuel pressure regulator or injectors to see if they are working and what else could it be?
I would very much like you help because she loves the car and I do not want to get rid of it (she has had it since new and has about 60k) Thank in advance for all your help,
