Holley Dominator EFI hard starting after warm up

[andrewb70]

Mario,

The distributor is SUPPOSED to be locked out. The timing is handled by the ECU!!!

There is a place in the software where you can set timing while cranking...

Don't take this the wrong way, but please take your car to someone that knows EFI inside and out before something bad happens...

Couldn't agree more. This is not for beginners to learn on --- you can ruin a motor in nothing flat.

Okay to learn to do certain things --- idle adjustments -- open pages and look at fueling -- or learn to understand what the IAC or O2 sensor is telling you... so you don't have to have a pro every time you want to make a minor adjustment to one or two items.

Not sure who tuned this in the first place ----- maybe we don't want to know --- but cold and hot start is all part of that tune ---- if it didn't happen - then please don't recommend them.

Andrew that's exactly what I did. My car was at one of the top tuners in the country !!!!! And this was how I got my car back. It took my nephews tuner who does of all things drag boats and snowmobiles, 5 minutes to figure out my Holley system wasn't controlling my timing . He retarded the timing and the car started perfect . It's frustrating as F@CK I can tell you that . We are taking it tomorrow to my nephews tuner he rented some dyno time at his friends place . So will see what happens.

If the Dominator was not controlling timing, then something is wrong with the installation. In other words, the wiring is most likely not set-up properly in order for the ECU to control whatever style of ignition is being used. The Holley supports many different popular ignition options, but they must be a) wired correctly, and b) subsequently configured properly in the ECU.

I hope that whoever works on it next can do both a and b.

Good luck!

If I had a dime for every time I heard this I'd be living in Beverly Hills CA.
Unfortunately there are still more crappy tuners out there than maybe we think.

Mark you have no idea! My car has been to three tuners . The last one got the car running awesome . That is when you can finally get it started. So you ask,'' Was it doing this when you had it?????????'' Of course it wasn't!!!!!! HOW THE F@CK CAN IT NOT ITS TRYING TO START AT 38 DEGRESS ADVANCE!!!!!!!!!!!!!!!!!!!!!!!!!! We go to the dyno tomorrow My nephews guy has the place rented for the afternoon. This will be the first time I'm going so I can see for myself that everything is good to go.

Mario,

Sounds like this whole starting issue is like an electronic ridle(r).

Mario,

Good luck at the dyno today.

I am usually hesitant about people bad-mouthing businesses on social media because it can shut a place down in a hurry, but when someone gets totally raked over the coals other potential customers need to know. I HATE(and I don't like that word)hearing stories of incompetence or down right thievery.

Best of luck, keep us posted.
Regarding the timing issue, I've always told others just because you CAN do that doesn't mean you SHOULD do that. Plus too many charge too much $$$. This ain't that difficult.
Again best of luck.

Well we had a productive outing at the tuner last week . The car starts perfect now. It wasn't hard to figure out the starting problem it was trying to start at almost 50 degrees advance !!!!!!!!!!! We thought it was 38 degrees at first but we were wrong. Now with the MSD starter saver it works perfect. I'm going to run it this way until Holley makes the distributor I need . They currently don't make the short version I need for my car.
