Help! Fuel cut switch/button on ECU?(Clifford 700 alarm)

Check the fuel cut-off in the rear of the trunk...there a panel on the right hand side against the back of the car that you can stick ur hand in and hit the top of the black box (relay size) and push the red button down. It may have tripped some how...it's happened to me.

Also, even if it's not tripped, disconnect it and put a wire btw the connections and jump it...may have just gone bad. That has also happened to me. You will have to remove the rear panel, but that's a snap.

You also need to verify juice to the fuel pump at the rear harness...if you have juice, I would recommend hooking up a fuel gauge to the fuel rail and making sure you have pressure.

You can check spark by taking off one of the plug wires...putting a screwdriver up inside to make contact and then placing it near metal while someone tries to crank ur car...you should see spark jump to metal and you wont get fried doing it.

If you have fuel / spark / checked the fuel cut-off, you will have to start trouble shooting the fuel pump relay up behind the glove box and the CCRM in the fender to make sure juice is flowing.

Also, do you have a spare key? It could just be that the key transponder went bad some how and is not deactivating the PATS system.

That is exactly what it was! The transceiver went bad and couldn't read ANY key chip. $240.00 at the dealer. Just wanted to let everyone know to include it in crank/no-start troubleshooting. Apparently it is fairly common in sn95's.

thanks for the troubleshooting step-by-step anyways. I'll keep it for future use if needed.
