Does the fuel pump run?
Have you got pressure at the fuel rail?

Bolting a '90-'92 harness in an '88 won't work, pin locations are different.

i kno pins are different i repinned the c100. the c207 under the dash is a little different. can't find any diasgrams on the 207 for the 88 sure it can be done just need some help with the wiring if anyone has the diagrams i would sure appreciate some help the fuel pump comes on and getting fuel to the rail but i dont think the injectors are opening
