I have a vs v8 commodore ute series 3 I replaced the welsh

Customer Question

Hi, I have a vs v8 commodore ute series 3 I replaced the welsh plugs because they were leaking and did the seals while doing this as the motor was out, everything went according to plans and the car started fine but after taking it for a few test runs it just stopped! Since then have put in new coil and distributor still won't start, it cranks over and backfires a bit sounds like it will go but nothing. Got plenty of spark and is getting fuel
JA: Have you checked the engine's fuel supply? And the spark plugs -- are they all working?
Customer: Yes seems to be getting fuel and all plugs working
JA: What year is your Commodore?
Customer: 1999 series 3
JA: Are you fixing your Commodore yourself? What have you tried so far?
Customer: Me and a mate are and he is fully qualified mechanic. We put in new coil and distributor
JA: Anything else you want the mechanic to know before I connect you?
Customer: I've also got a new pcm but haven't had it programmed as Holden mechanics say they cant

Hello! My name is Gary.
Welcome to JustAnswer.
The car just stopped, instantly like turning the key off, or gradually like running out of fuel?

You have spark at the plug leads, and fuel pressure?

When did the PCM change occur?

Do you have access to TECH2 for this?

VS Series III ute came out when VT came out, Holden should be still able to program for you.

Hello again,

Do you need any further help?

If you fitted a new distributor, have you set the ignition timing correctly?

I hope my advice has been of assistance to you.

Kind regards
