How did you test for no injector pulse? Do you have 12 volts at the injectors with the key turned on (in the run position)? Every injector has a pink wire on it - this should have 12 volts with the key on.

Hi, does the starter crank? If not, check the circuits at the starter relay. Terminal 30,Voltage at the load/switch side of relay is hot all the time. Terminal 85, Voltage to the coil side of relay goes hot with the key in the crank position.

Yea its turning the motor over but now we think the starter went out and something else happen to go at the same time. Just my luck. But we dont think its gettin any fuel for some reason. You can hear the fuel pump come on though, and it was just changed about 1 yr ago
