He said he adjusted the decomp,it may not be opening the exhaust valves at all,and the starter working overtime?he's jumping it with a truck battery and it's turning the motor over slowly?If the starter is stoping after only three revs I'd be checking to see if the exhaust valves are opening at all.

If the starter has gone 3 revs (since you can only hear it huff once in 2 revs, this is actually 6 revs) the decomp adjustment is fine.

If the starter stalls on the 1st rev, then you got a problem.

If the battery drops to 6 volts then THE BATTERY IS SHOT!!! It won't start with 6 volts no way no how. I think you are performing brain surgery on a hangnail! REPLACE THE BATTERY!!!

Battery Could be good, but won't be for long. The car battery doesn't work, either. Test voltage with start button pushed, without the starter wire connected. DO THAT. By b I don't CARE if nobody else sees why. Don't let it short out.

Sorry I have been busy the past couple days. I'm an audio engineer and am out of town with a band until tomorrow. I will definitely test without the starter connected. Hopefully I will be able to record a video and show you guys what it sounds like. That may be very helpfull for you guys to hear it. Thank you all for your help in this.

Removing the plug is not an accurate test.
Without the load of compression the electronics don't see the voltage drop, which we have seen is significant.
And, he can bump start it, so, it does spark. But not at six volts.
Let's find out if there is a parallel load somewhere that's dropping the battery voltage. I doubt it but it's gotta be checked.

You can't ignore the 6 volt issue. You may have bad battery cables. The crimps are loose? If there's resistance at all then all the current will dissipate there and not go to the starter motor. Basic troubleshooting should get to the root. You can't ignore 50 years of experience and expertise. You get all kinds of things to try but did you check the most basic things first? Cool

You are saying the starter motor makes a clicking noise after a few revs? Pull it apart and check the field magnets for cracking or pulverized. Check the armature for burned coils and the brushes making good contact. If you are using good jumper cables and still have the same issue then the starter motor is cooked or the internal starter gear is jamming (cracked case)? Try running the starter motor out of the engine for a few seconds. How does it sound?

You say a new starter as in different or brand new? Get another one if covered by warranty. I've purchased a brand new starter off Ebay for $89. ish and they work great. Cool

Re: Another won't start thread Reply #42 - 08/20/16 at 16:31:51 Until you either pull the starter cable and hit the button and check the battery Or Pull the cable and, somehow, without wrecking the threads, hook the jumpers up straight to the starter motor and a close ground, you won't know if there is a parallel load.

Ok I am home today and finally got to test some more.

My starter is a brand new aftermarket starter. It has never been used and is not a reman product.

I connected my battery to my truck before I started any tests.

I pulled the hot from the starter and checked the voltage when I press the button. The reading is 12v without it connected to the starter.

I went ahead while I had the cable off the starter and tried it straight from my truck battery. I connected the ground jumper cable to the bolt on the frame and then touched the hot jumper cable straight to the post on the starter. Same condition as before.

I reconnected the starter cable and I reconnected the jumpers from my truck back to the battery. I took a video of the meter as it was metering the post on the starter so you could see and hear what it is doing. This time the voltage was only at about 3-4v.

Any other thoughts?
