hey guys so finally got the car running. been searching but cant find exactly what im looking for. im running a jwt ecu with n62 maf and nismo 740s. with a jwt s1 cam, it wont start first crank and need to feel it some fuel on second crank for it to start. then even after its warmed up it runs at 10-AFR. and vac is around 300mmhg. any ideas?
Sounds likes MAF wiring. Confirm?

Do what the pic says. I had an issue with JWT wiring. Once I ran one ground to chassis, the MAF worked like a charm.

FYI. I ran the ground to the one harness ground behind the headlight on the passenger side. I am running blow through but I believe there is a harness ground on the driver side if draw through.

Just making sure you grounded the first black wire to the chassis, then the second to the harness. Make sure they are making good contact and solder them.gold zenki wrote:Ok so wired like supa said grounded to the chassis and same thing. Any other suggestions. I soared all the couplers and hoses with electrical connector cleaner and nothing changes. Any more ideas

What are the specs with the JWT tune? What fuel pressure are you running?

I just wonder if the tune has an issue. Pretty sure it does not but never can tell.
