Bypassed VATS/Car Wont Start

I Bypassed vats with resistors got all that done....
Bought a new starter relay thinking it was that

Car doesn't do anything when i hit the ignition
What should i check next? neutral safety switch

p.s. When i manually add power to the starter from the battery the car cranks but doesnt fire up...

Re: Bypassed VATS/Car Wont Start

be sure the block is properly grounded. One cable from the neg batt to the chassis, one from the chassis to block, one from the block to the firewall. Sounds exactly like what I had one do to me.

You didn't bypass VATS ; all you have done is make it "think" the correct key is in the Ign

Everything in the starter circuit from the wire out of the Ign switch to the starter solenoid ;
but read below 1st

(with key on ????? )
That would indicate a problem with the VATS module; it is not sending the fuel enable signal to the computer
( or operating the starter relay)
