When you turn the key on the pcm should put a ground on pin 85, providing the contacts are closed in the inhibitor switch on the trans. When you turn the key to start battery voltage should be on pin 86 and the main contacts will close in the relay switching battery voltage between pin 87 and 30 which will flow to the solenoid. With the key off there is no ground on 85, to be sure I checked my straight gas bf. If your inhibitor switch is alright and battery voltage is going to the pcm you have to find out why it wont put a ground on with the key on. Do's every thing work dash lights and cluster what about when you cranked the engine did you see the tacho move indicating there is a crank signal, also when you turn the key on the ignition relay should supply power to the lpg fuse and relay.

all dash lights work but brake fail light comes on when you try to start the car should i hear the gas system prime when i turn the key
