2004 VY berlina 5.7l LS1
Hi all just wondering if someone can help me with an issue thats starting to drive me crazy... 2004 vy berlina ls1.
Have a cold start issue which results in cranking.... But no start... Ive found if i leave the key on let it sit for 5 mins or so the car will start.. Now ive read the forums and ive done just about everything to cover whats already been mentioned. List if repairs so far.
New fuel pump sending unit and pump
New crank angle sensor
New cam position sensor
New filters
Relays replaced
Car cranks good battery is fine starter is fine key has good contact.. Imobilsier switches off when key us turned so i can rule out the key and contacts.
I have hooked a noid light up and cranked i get no injector pulse.. But like mentioned earlier if i turn key to accesories and leve it for a few minutes then crank she wil get a pulse and fire up... Any infor or hel would be much appreciated.
