No start issue Holley HP EFI

GUMP · 05-23-2020, 07:39 AM

I have had a similar problem on two occasions. Both times it was the starter going bad. It would turn over, but not quite fast enough to properly sync. Everything else checked good.

I found it the first time by disconnecting the injectors and removing the plugs. After that it would sync. perfectly.

I think Robin had it happen to him when he had my 2014 COPO.

No guarantee this is your issue, but worth a look.

Robin comes on here a good bit. I'll send him a text.

Hey I'm up for just about any suggestion at this point. I'll double check the grounds and make sure everything is clean then put it back together and give this a try. Worth a shot if nothing else to eliminate another variable. Thanks.

Well tried a new a starter and battery. It definitely cranks faster but same result

Do you have any add on devices plugged into your harness?

JRyan · 05-25-2020, 01:11 PM

No sir. Nothing extra wired into the harness.

The only other thing that I have had happen was the crank signal wire getting pinched between the starter and the block.
