Hii, I have a 2004 VZ SV6 (LY7 10H7C) with starting issues which I'm hoping someone can shed some light on, Car cranks but just wont fire
Tested spark: Good spark
Sprayed some aero start down the guts and got some backfires
Couldn't hear fuel pump so checked fuse/relay which turned out to be in working order then decided to purchase a new fuel pump and assembly,
after installing this and putting the tank back in to my surprise the fuel pump still wasn't priming, Me being me didn't think to use a test light at the pump before putting it in
Still cant hear the fuel pump priming
Cluster shows system ok! then it shows service vehicle soon
Not very mechanical minded but after some research people with similar issues went in the direction of replacing camshaft position sensors (i believe there is 4?) and some mentioned the oil sensor/switch
Upon inspecting my oil pressure sensor it looks brand new from the outside and seems to be intact, no oil around it at all
The camshaft position sensors (2 near the PCM and 2 on the other side (pretty sure im looking at the right sensors) they were pretty oily so i cleaned them up with some contact cleaner(hope thats not bad)
Everything else on the car seems to still work fine, keyless entry, radio, lights etc
My old man has a cheap diagnostic tool, I will run a scan later tonight and update my findings, in the meantime does anyone have any input on what I could try? I have a test light but no multi-meter (looked at them in the shop but no idea how to use them and didn't want to do further damage)
Cheers, Toast.
