I've been slowly working on getting my truck ready to add the turbo I bought. So far I changed out the valve covers to the turbo covers, and put in the turbo wiring harness today. I wanted to crank the truck up, and make sure all to this point was 'good to go', and let it run before moving on with the turbo install.
Well, no fire at the end of the day. The truck has been very reliable, and will fire up even without gp's; as the temp here is in the 70's. Between the wiring harness, gp replacement, and the valve covers, I'd been laying all over the engine. I tried to be very careful of all things, but did end up bumping into the fuel system often while removing the original harness, and replacing the gp's.
I haven't had a chance to trace down the issue further as my daylight was leaving. With the key on, I checked voltage at the FSS, and it had full battery voltage; so I'm kinda stuck thinking it's actually air intrusion at this point. The engine has 80k miles on it, and half the return system has been replaced; half is original.
On a hunch I just read Agnem's website regarding return lines, and it states:"Typically these return line systems are very reliable until disturbed by nearby mechanical action, which may break the contact surface seal of any component in the vicinity. Once a component is disturbed, it is time to service the entire O-ring and cap system. "
I'm no bull in a china cabinet, but can bumping into, or light pressure cause 'nearby mechanical action', ending up breaking the seal?
Fwiw, or extra information the glow plug controller isn't working I did put in new gp's, and am going to convert over to a push button; the relays good.
