So have you took the injector out and cranked it over with the injector wires hooked up to see if it sprays?
Is the fuel pump making it's priming noise?
If no fuel and no noise...
Find the little orange plastic fuse holders under the hood. (2)
The one for the fuel pump & injector has a white wire, and a white/black wire.
Open it and a 10 amp fuse will be inside.
Pull it and check it.
If bad, replace...
If good, replace and move back to the fuel pump relay.
It will have these color wires...
White/Black ... White/Red ... Yellow/Red ... Black/Red
Unhook it and swap it for the Fan relay, which has blue wires going in
Try again... if it works, swap back and try again... and if it does not work, bad relay.
Swap for one of the starter relays with a brown wire going it until you can get a replacement.
This will allow you to start up one way but not the other...
Either only in neutral or only with the clutch pulled... (pick your pony)
If none of this helps, and you have no prime and no injector mist, unhook relay again.
With switches on, check inside on the plug terminal for power between...
Yellow/Red and frame
White/Black and frame
Both should have power
If yes on prime noise and no injector spray...
Clean injector and try again.
No dice, check injector circuit.
First do audible inspection to see if it's clicking
Next unhook it's wire...
Hook meter to injector terminals to check resistance.
Meter (+) to
Meter (-) to
Hook meter to incoming wire plug to check for voltage.
Meter (+) to White/Red wire terminal
Meter (-) to battery negative
Meter (+) to Blue/Red wire terminal
Meter (-) to battery negative
Turn switches on... reading should be battery voltage for 3 seconds, then 0
(both tests)
