Ok so we finished swapping the sr into my datsun 510...



We thought we had a fuel problem as the first time we took it out on the road everything was going fine and were just taking it easy and we encountered a hill and the car started sputtering then died, and wouldnt start back up (starter was fine and cranking)

So we thought it was a fuel issue, but fuel pressure is good. We got a gauge and tried different FPR's and it is holding steady at 42psi

Also tried two different fuel pumps
checked injectors and rail, no blockages, injectors are not leaking any fuel and the o-rings are fine.


So the next time we took it and drove it around the parking lot everything was going fine just driving around and low speed, then parked it and it idled for a while and then died. Couldn't get it to start back up again.

I just want a running car... gah


All the coils are working fine, we checked them, all the injectors are firing as they should.

The timing might be a little advanced but nothing to cause this issue.

Tried different MAFS and I put in a new CAS it seems to be working fine.

The ECU has a emance tune on it but we made sure the daughterboard was on properly , and the car did run fine around the parking lot when we tried it (and wouldnt run without addon board)

any thoughts would be appreciated!
