car wont start after paxton install

[Blazer707@TBR]

Who's base tune are you running to get the car going?

Also did you have to rewire/ cut and splice anything?

sounds related to injector harness ground/plug

What bap are u running? There was another guy on here with the programmable Vortech that had problems starting as well.

I believe his was a priblem primeing. But it would still start after a long crank.

During the paxton install you need to relocate a couple ground wires from the ECU. Make sure those are secured and are getting proper grounds.

disconnect the BAP rewire like stock and it will run. Then get the Kenne Bell BAP and max it out no more problems.

His problem isn't a bap issue since he here's it prime. It has to be injector harness issue. It could also be the cone tip. At the TB. Any codes?

Check grounds on bap and ensure you're getting power. Check inertia switch in trunk. If no luck then disconnect bap, hook up fuel pump wiring as it was stock and re-attempt starting. Can you hear your fuel pump priming when the key is turned?

Bap is working fine, just incase I rewired it stock and it acted the same way. You can hear the fuel pump priming just fine.

Intercooler on the correct direction?

How could that effect injector pulse?

I am using Shaun (aed) base tune, I also put the stock tune in and it acted the same way.
No I didn't have to rewire anything with the Paxton install.

It is the vortech universal, his was different.

I will look over my install, but I don't remember relocating any grounds.

Did that and it is acting the same way.

Thanks for all the attempts guys I appreciate it.

So i just hooked up the sct and put it into datalogging and checked maf freq with car on and it was .81 and checked tps and it was 4.10 this was with engine off car on.

.

It shouldn't but I had similar issues as yours when I had mine on backwards. The MAF plugged in from there so I didnt think anything of it. I could ususally get mine to fire though. It just wouldn't run.

Try disconnecting the MAF it will idle fine but run like crap if you do anything else but start if thats your issue or related issue. I don't think it is but its a quick thing to check.

 

[busarich]

I will go try that. The intercooler is on as per the Paxton directions

 

[busarich]

Disconnected maf and same thing

Do the ID1000's have injector adapters to fit the stock wiring harness? If so, one or a couple of those adapters might be bad resulting in the injector not working.

Not 100% sure but that's just a thought.

 

[busarich]

No sir no adapters. They plug right in.

 

[busarich]

Do you guys know what the tps would read at idle? I read that on start up (on older mustangs) if it was was higher than a certain voltage that it would cut fuel to the injectors. Im going to test that tonight.

 

[RFM50]

You might want to call Shawn, it might be a problem with the base tune. I have gotten tunes before where the car won't start up.

 

[busarich]

I did and he said it was good. I also put it to stock and its doing the same ?

Weird! Have you tried switching back to the stock injectors to see if that changes anything?

 

[busarich]

No i havent done that. I will try that but i dont think it will. With the stock tune and injector plug disconnected it still doesnt test good.
