Re: converted to maf now car wont start!!
The 88 cali car will work with the 87, I was just checking because if you try & use a newer maf set up like a 90-93 on an 87-88 the problems you are having will happen. First off why are you having to jump the fuel pump from the relay under the drivers seat? Is the fuel pump not coming on when you power the car up? Second did you change the map sensor on the firewall with the one from the 88 car. They are different. The non maf cars have a vac line connected to it from the upper intake. It's a pretty straight up swap. Let me go back over it. You will need the computer harness, computer, maf sensor with the bracket, air intake tubes, & map sensor from the 88 donor car. Remove the same parts from the 87 & install the 88 parts in their place. Also use the 88 fuel pump relay under the drivers seat to help with your trouble shooting. Double check your engine & computer harness grounds also.
