help!!! car wont start

[vn1989]

i own a 1989 vn commodore series 1 and it was on gas but i removed it because it was buggered needed 2 have all the gas lines redone and bottle restamped so i removed it.. the bottle and the lines came out fine but i got to the ecu area and cut out all the wires for the gas but not my car wont start. i changed the engine loom because i thought i cut some thing i shouldnt have but it still wont start its getting spart and turning over but just wont fire

are you getting power to your fuel pump ? sounds like you might have cut a wire to it

[vn1989]

no i dont think so cant here iw whining when i turn the key

Check for power at the pump connector, if no power check the fuse and see if the relay is working. If there is power maybe the pump has packed it in if its been using only the gas for a while

i also have the same problem with my vn station wagon, removed the gas system and the car wont start, i have fuel at the rail, spark etc im thinking maybe with gas systems they wire something in to cut injector pulse? question is where do they tap into the car to do this? anyone with any experience with gas systems provide any feed back?

[vn1989]

i had the same problem i changed the engine loom because i couldnt figure out what they did with changing wires and soldering stuff in.... thak god the gas is gone tho... im pritty sure they wire it up so when its running on gas the ecu stops sending the pulce 2 the injectors but i found this out after i finished

[strgas]

check for power at the injectors , the most common injector cut was at c 14 and c 15 wires at the ECU , depending on what system was wired in before hand there might have been external relays fitted or the lpg module had internal relays . also a fuel cut relay may have be used or not , any info on the lpg system that was fitted would be a good start

Did it have a switch that could choose between: gas, fuel, and nothing (security purpose I suppose). My mate had one and the car wouldn't start, turned out it was switched to nothing, cause maybe you left that on gas, or nothing.
