Is the relay clicking in the fuse box under the hood. It is next to the EFI relay. Do you have a volt meter and an average knowledge of how to use it? Is the battery fully charged?
Pull the relay out if you put a jumper wire from the pins 3 to pin 5 does the starter engage?
I did not say that the relay was the problem. If you pull the relay out the two parallel pins are for the relay windings and pin one which is the closest to the EFI main relay receives 12 V by way of the ignition switch after power goes through the neutral safety switch. Then goes through the coil winding and out pin two to the ground to energize the relay. Pin three and pin five are the pins that are perpendicular to each other and are the other two pins. Pin three should have 12 V all the time and pin five goes directly to the starter solenoid. If you take a jumper wire and go across pin three to pin five the starter should engage. If you're still not certain which pin is which let me know and I'll see if I can find a diagram. As a test you could swap the EFI relay into the starter relay position and see if the starter engages but it's not likely that the relay is bad although it is possible.
Do you have 12 volts at the starter relay pin 3? Are you saying that if you jump 3 to 5 and you have 12 v at pin 3 and the starter will not engage?
Check the 40 amp main fuse this feeds pin 3. This is next to the headlight relay and the other fuses in the same box. If you take a jumper from the Positive battery terminal to pin 5 can you get the starter to engage?
Pin 2 which is one of the parallel pins and is on the outside edge of the fuse box is the ground circuit and should have no voltage. Pin 1 which is parallel to Pin 2 and is closest to the EFI main relay should have 12 V when the key is turned to the start position. Pin 3 which is closest to the horn relay should have 12 V all the time and pin five goes to the starter? can you make the starter engaged by applying 12 V to pin five?
there is no voltage at pin1 when the key is turned. where do i check next?
At the neutral safety switch towards the center of the connector there are large gauge wires. One is black with white and one is black. These are the input and output wires from the ignition switch. Do you have 12 V to either these wires with the key in the start position? Remove the connector and check these wires. If you put a jumper wire between these two wires in the female pin side of the connector does the car start with the relay installed and does the relay click?
Down on the front of the transmission follow the dipstck tube. It is behind the shift lever.
