I have a 1988 fox body g.t the car will not crank it turns over but will not start.When i turn the key over the fuel pump will not come on. its not the fuel pump because i hook a battery up to the plug in the pump works.I traced the wires to beneath the hood to a plug in of wires pull them apart jumped the pump to the battery it runs there also. All in All it wont crank. Brent Bowers Elaba Alabama

 

in front of the driver side tail light there is a black box with a white nobe which is ur fuel cut off switch on it make sure that it is pushed down i had that problem with my 88 50 when i kicked it

 

relay/fuse might be bad also?

 

Fuel pump relay is under the drivers seat, could have a wire grounding out and blowing the relay. Check for power to the relay, then check from the relay to the cutoff switch in the trunk, then from the trunk to the fuel pump. Just isolate the trouble spot and replace.

If you don't have power to the relay, then it's between the ignition and the relay

 

inertia switch isnt the prob. i bypassed it. the diagram says the fuel pump relay is in the passager side firewall.help please

 

Car will not stat fuel pump is not humming when i turn the key over feul pump works i hook it to a battery inertia switch i baypassed can anyone help

 

check the fuse under the hood

 

were is the fuse under the hood located do u know

 

I merged your two threads but what has been stated above will help you isolate the issue. You also have a switch on the clutch that may be broken or not making contact. You may bypass this switch by jumpering the wires.

 

Check under the hood for your fuse box. Pull the cover off and there should be an illustration showing you which fuses are where.

 

bad ignition switch? does everything else power up like it should?
