[chubz7793]

Hey guys I'm back finally the swap Is complete I've checked the injectors coils everything is working as it should. Problem one the car won't start with out starter fluid 2 if you give it any bit of throttle it cuts out I'm puzzled not sure what's going on can any one give some advice ??? Thanks

if u need starting fluid..
u lack fuel...
make sure fuel pump is on...is getting 12v...and it a walboro...

i was hinting toward that its a stock one just to get it started i'll be ordering one this weekend 255 right ?

Have you checked your fuel pressure??

[Drift N Dragg]

You need the Walbro 255....

Make sure you have a functioning FPR or get a Adjustable FPR.. because if you don't, you will be pushing Rich..

IIRC, RB20' use the 215 LBS Fuel pump.. On my person RB20 swap I had to run an FPR.. bring my fuel pressure down... that or get a Nismo FPR..

As stated check fuel pressure. Also check fuel lines. High pressure line goes on bottem fitting return is on top.(i made this mistake) if those check out check intercooler connections for leaks. Then check the hose off the turbo to maf. Crank breather hose bov going to the maf. Etc. Any leaks or disconnected lines will cause your symptoms. Last thing to check is the maf wiring. When i got my swap the wiring had been pinched. I ignored it at first then found out those wires are really fragile. Where they where pinched the wires broke inside the insulation.

changing your pump will solve future issues. but it will not solve this issue. unless your pump is bad. do a little further diagnosis. the stock pump is plenty to make the rb run. just dont go drive it around you will run out of fuel quick in boost.

I wish I could drive it the cutting out is so bad it won't do anything

fuel pressure goes to 40
psi and slowly goes down
