I recently put in a new clutch, after I was done and only had a hand full of screws I forgot what they went to, I fired up the truck. Ran for ten seconds then shut off, I dance then have replaced fuel pump, everything that deals with the distributor. Check all fuses and relays. But for some reason fuel pump will not work nor will the sparks plugs fire. Before the clutch went out I was having problems with periodic misfire in number two, random stalling while driving and having to wait five minutes before it would start again. Any ideas?

Hi and thanks for using 2CarPros. Com.

Since you lost both fuel and spark, I would recommend starting the the automatic shut down system (ASD). Here is testing information for the ASD and Fuel relay. Note: If the ASD shuts down, you will lose both spark and fuel. The ASD is located in the power distribution box under the hood. I have attached a picture.

TESTING AND INSPECTION
The following procedure applies to the ASD and fuel pump relays.
Remove relay from connector before testing.
With the relay removed from the vehicle, use an ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75 ±5 ohms.
Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity between terminals 30 and 87A.
Connect the ohmmeter between terminals 87 and 30. The ohmmeter should not show continuity at this time.
Connect one end of a jumper wire (16 gauge or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12 volt power source.
Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt power source. Do not attach the other end of the jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS TEST.
Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The ohmmeter should now show continuity between relay terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and 30.
Disconnect jumper wires.
Replace the relay if it did not pass the continuity and resistance tests. If the relay passed the tests, it operates properly Check the remainder of the ASD and fuel pump relay circuits.
