No start, low rev starter, rapid clicking from under dash

[mr_squishy]

New to the forums and new to this truck as well. Early 99 F350. 6-speed manual 4x4. Guy I bought it from did hardly any maintance on it. Long story short, replaced o-rings on fuel lines, took care of MOST of the leaks, new CPS, new fuel filter and fresh oil change.

Go to start it this morning, turn the key to ON, hear a few clicks under the dash. (???) let the GP do their thing, wait an extra 20 - 30 sec after the wait to start light goes out, and it's slow to roll over. Hmm, OK put on a charger and took the car instead. Don't know how old the batteries are. (Probably few days older than dirt, but not orig) Gonna go to NAPA and get some new ones.

Had a problem with it yesterday, stopped to pick up something from the store was in maybe 30 min, truck didn't want to start. Seemed to roll over fine, tried to start it about four times, (off, wait 30 sec for GP after WTS light, roll it over) and the forth time it took, but low power (limp mode?) Restarted while rolling (didn';t wait after the WTS light) and it did just fine. turbo even started spooling earlier about 1600 rpm. Any ideas?

pulled the IPR sensor (inside valley, drivers side head) soaked with oil. left it off. got a few hits, but didnt have much umph left in batts. was boosting with a 6.2L c-2500 (bad trans, its gonna leave soon)

Ok, for grins I checked my terminals 3 of 4 were not quite tight battery brushed ad snugged them down, rolls over better and with a bit of grey smoke it FINALLY took. Idled on what sounded like only 3 cyls with the IPR disconnected and a Service light on. Put it back on while running, no change, no throttle response. stopped it, restarted, no SES light, runs better. Its warming up now. gonna recheck the GPR and GP's after I go and get some hay.

After the warm up, ran fine. Pulled a 20ft tri-axle trailer there no problems. Idled while loading where it developed a lope on idle and low pull situations. Lope cleared under moderate and heavy pull (lots of throttle). Noticed that the SES light flashed briefly on way back. Its home now, gotta check out that ICP sensor... Anybody know where I SHOULD go to get codes read? Will Autozone's handheld reader do it or is it off to the dealership?

I would go to Autozone What size batteries are in your truck ? Are they identicle?

[wildchild]

I think you have a low voltage problem
Also on the pass side pos cable what does it look like such as corrosion dark swelled insulation just passed the terminal going to starter that can also be bad

[mr_squishy]

Yeah it was. quick scrub with a terminal brush and tightened it down got it started. Doesn't seem to be that anymore. Clamps looked OK, a little hammered, but didn't look corroded too bad. I will check further down the cable and see what's going on. Thanks!
