Just finished my bischur stg 4 by adding 660 cc injector, 1 step colder idirium plugs gapped at.25 and the BR440 turbo kit

Now for some reason it takes a lot longer for the engine to turn over. The started is working fine, the batt is good. It has trouble turning the engine over. Not sure why

It only does this when it hasnt been turned on for a while. If I am running about it will turn on normally.

Is this normal with larger injectors or is something not functioning correctly.

Anybody else have this problem or know a soltuion to troubleshoot this issue?

 

Turn the key/ignition to ON for a couple seconds or so, for the fuel pump to kick/turn on & send fuel.

My friend has the same quirk with his Walbro fuel pump in his MR2.

That *should* be what's going on.

 

i will try that. Thing was I had the walbro in a for a while. Maybe its cuz of the larger injectors?

 

I will try your advice in the AM.

Thnx for the tip

 

I am having the same problem after putting the bigger injectors - Precision 780cc with 264 cams

since you have the same problem, i guess that is normal.

 

It's dumping alot of fuel b/c of the bigger injectors. you need to lean it out with a AFC or get a reflash.
