2 problems...need some help

[maccavvy]

right guys couple of issues.. unrelated but hoping for help .2004 cv8 ls1

ive got some saas aftermarket gauges fitted the oil pressure seems erratic of late.
cant find any loose connections. today on my way home gauge read zero.
stopped engine ,on the flat,checked oil level and looked for leaks, all good.
started it up, gauge went back up and was fien all way home. im thinking sender breaking down when hot. ideas ??


2nd issue.. shes a bh to start from cold. fine when driven but left over night takes either a very long crank to fire, or 2-4 goes to catch properly. any ideas.??
car has new plugs and leads less than 2k ago .
cleaned air filter out, and re oiled, this hasn't made a difference neither.

Does it fire on turn over but then stall or just never fires.

Could be idle control valve sticky.

Also any hunting when started or high Reving

doesn't fire when turning over.. then tries to catch..usually 3rd time fires up perfect.

once running it idles and drives perfect.

Fueling issue. Check your fuel pressure first thing. Change your fuel filter. Pop out the tank pump and clean the filter.

All options.

ill see if I can find someone who can test the fuel pressure .

ill order a filter too..

spoke to the fish they said to get a diagnostics done too.not heard of my exact problem but similar could be cam sensor too
