Ive just installed a new pmd box and tried it out , the truck still wouldnt start, and i put a new fuel pump relay, ive got one hot wire going into the relay and one hot wire going into the injector put plug in, still NO power to the fuel pump, i straight wired the fuel pump and it works, tried to start it again with the fuel pump wired up and still wouldnt start, really need to know if theres only supposed to be 1 hot wire on the fuel pump relay, and only 1 hotwire on the injector plug in?

-pmd works
-fuel injector works
-fuel pump works

If you might have any ideas of what else could be my problem, any info would be greatly appreciated
 
thanks

yes the fuse is good but theres no power going to the plugins for the fuse, checked the wires with a test light and there was nothing
 
symptoms of a bad crank censor?

what will the symptoms be if my crank censor has gone bad?
my engine is cranking, and like i said in the first thread all that is working, will this make it not fire?
where is that censor located?

thanks for the help
 
I dont know what all you did.
1 wire at the relay is allways hot,key on or off.you can jumper pass side front terminal with fire wall center terminal to run the LP.
grounding the fuse should run the LP as well.
Check for bad grounds at the pass side rear of head.the LP grounds there as well.
Look for broken ground strap behind the downpipe,from head to frame to firewall
Test for power at the Fuel shut off sol with key on,check fuses.

Any codes?
