Getting frustrated with my 7.3
I'm having starting issues. Since the weather started to change its been getting harder and harder to start my truck. I thought it was the batteries so I had them tested, they are ok. Checked the alternator, tested fine. So next I changed the GPR, no change. I've since bought new glow plugs to replace this weekend while I change out my exhaust manifolds. But Im wondering if its even the glow plugs. The temp has been about 30 at night and 50ish during the day. At night I've been plugging it in and putting the batteries on a charger because the constant cranking during startup is ridiculous.
I do let the "wait to start" light cycle twice before I crank and it just turns and turns. IF its plugged in and the battery charger is on, it will eventually fire after 2 - 3 attempts. With some white/grey smoke and a little bit of hesitation when I give it "gas".
Here is the reason I'm wondering if its the GPs. I can run my motor for half an hour, shut it off for minute and it does the exact same thing. If the motor is hot, would it even matter if both banks of GPs were junk because its already hot in there? lol Then it brings me back to the battery issue, if they test out ok and the alternator is working properly why does it seem like they arent holding charge?
I'm eventually gonna replace the GPs and batteries, probably this weekend. I suppose I'll see if that has any effect but I wanna check to see if anyone else has any insight. thanks in advance guys
