Idk about the whole ignition aspect but
are your lights working? dash? windows? etc?

If so when you turn your key to acc i believe can you hear
your fuel pump kick on?

Re-check all your grounds.

Dont go straight to ignition.
Most likley your last thing to go out
unless you've messed with it before.

Wrong. The pump does not run until there is an rpm signal, sent to the ecu.


To the OP, are you having a no crank or no start issue?
Do the dash lights come on with the key? Which ones come on?

Its pretty simple, you need 12V on the BAT ECU pin, and 12V on the IGSW ECU pin along with good grounds to E1, E01, E02 and you should have a working MIL light. Check those with a voltmeter and let us know what you find.
