Weird starting issue UPDATE
Gus - '78 2l FI
For the past year or so...every once and a while when I turn the key, the engine turns slower than normal, and has a laboring-grinding sound and doesn't start. Turn the key again and he fires to life and runs flawlessly.
Lately, have a heck of a time getting him started. Engine is turning slower than normal...sometimes with the "grinding" sound...often without. Usually, eventually will start...this AM...nope. Battery is at 11.95 volts. Connections all look solid.
Any suggestions as to what might be going on? The slow engine turning has me puzzled. Thanks gang!

Re: Weird starting issue
Maybe yer starter is the motor that's turning slow. Perhaps the bearings are worn and will occasionally bind causing the slow turning and the grindy noise. Yank that puppy off and have the FLAPS giver 'er a spin.

Re: Weird starting issue
Finally started after being hooked to a charger for a few minutes...but 11.95...should have fired right up, no?
Dick, starter is only a couple years old (I know...may still be the issue).

Re: Weird starting issue
Perhaps the starter is going bad and takes more amps then normal, which does two things, slow downs the turning of the engine, and lowers the voltage to the ECU.

Re: Weird starting issue
Timing that is set incorrectly will cause slow turnover. But no grinding.

Re: Weird starting issue
I agree with Steve. I KNOW for fact that the fuel injection system wants a nice healthy battery for it to work properly.

Re: Weird starting issue
You'll need 7-9 volts to engage the starter, and 10.5 v to fire the injectors.
She should start up with 11.95.

Re: Weird starting issue
What is the 'Volt drop' while cranking ? if you need procedure for checking it, i can provide

Re: Weird starting issue
Disable engine so that it will not fire when cranked. Limit cranking time to 15 secs or less.
1. set Volt meter to 20 Volt.
+ lead to batt post + and -lead to batt post - . [post, not clamp or cable] crank and note reading
+ lead to battery terminal stud on starter and - lead to starter housing. crank and note reading.
both readings should be the same.
2.set volt meter to 2 Volt scale
Pos. side of circuit:
connect + lead to Batt (+) post and - lead to the battery terminal stud on the starter. While cranking, note voltage reading
should be 0.6 volts or less
Neg side of circuit:
connect meter + lead to clean spot on starter case, and meter - lead to Neg. battery post. Crank engine. should be 0.3V or less.
if any of those readings is out, we can proceed further

Re: Weird starting issue
Ooo another thing, take off the connections and file 'em real shiny/purty. Connections corrode behind nuts. It can make a difference. At least give it the once over.

Re: Weird starting issue
why would this starter be tired after 3 years of relatively light use?
