3.8 '04 buick

[95SleeperAcheiva]

2004 Buick Lesabre 3.8L No start condition.
New cam Sensor, Crank sensor, ICM, ECU, dealer reflashed and security coded. We got everything but injector pulse, no ground signal from computer, B+ present. Checked all wires with ohm meter from cam/crank sensors to icm and icm to ecu, all good, checked all power to ecu and all grounds out of ecu also good.

First thing in the morning or after letting it sit for 15-20 minutes, crank motor, we get pulse and cam signal like it should for the first 2-3 seconds of crank and motor attempts to start, then we have a loss of cam signal, monitoring on scanner. Try to start again and no signal at all, pops a code for loss of cam signal. Currently, trying to swap out signal wire, because we don't know what else to do. Any ideas?

Its not a 60V6, that is the problem.

hey i dont own it! Its a customer but, i'm at my wits end, any ideas?

Set it on fire and call it a day. I dunno, with electronics I always check the grounds for corrosion. An 04 shouldn't have that problem but who knows.

hahahaha Ben is on a roll today!!

Yeah my guess is maybe a bad, broken, or pinched wire somewhere. Maybe even a bad pin in the connectors or a bad crimp on them.

Maybe the trigger on the cam is spinning free? Not sure if that's possible I've never seen how a 3800 cam is made....

To speak for weird electrical issues, I had my Alero (ecotec) in the shop for almost 2 weeks for them to diagnose a intermittent no-start condition. It ended up being a loose connection INSIDE the fuse block. I searched for a couple weeks before I finally gave up and brought it in. And I don't think I would have ever found that problem anyway.
