Injector install problem

ASSISTANCE Forced Induction
1

1990 RS, refurbished DSM blue tops, new Walburo fuel pump and TurboEdit.

ECU was chipped weeks ago, have burned and ran successfully different BINS without a problem. We installed the fuel pump in tank, car ran without problems before we started injectors. Removed fuel rail, cleaned up holes. dremeled out the lower rings for DSMs. Used new O rings and spacers from NAPA injector kit on the top of the injectors, the DSM O rings were a little bigger and put it all back together. Pretty simple, not much to screw up. Opened my current BIN for turbo edit and changed the Injector Sizing to 450’s, reburned chip and put in ECU. No good, car doesn’t start. Turns over, no sputter. Removed fuel rail, little bit of spray so was pressure in the fuel rail, reseated everything and put it all back together. No start. I downloaded a BIN for xenecrons stash alreaded tuned and sized for 450’s, car doesn’t start. Still not even trying to start, turns over but not even sputtering.

anyone have ideas for me to check? Thanks!

You download my BIN (made no changes) and it wouldnt start?

Check the wiring, any possible way you could have mixed up which clips went on which injectors?

not likely, the clips are the exact lenght. As for the BINS I d/l a couple from your collection, i would have thought it would have at least sputtered with the wrong BIN.

I’m gonna double-check all the connections tommorrow. Got a specific BIN I should try? BTW thanks for the help.

Yeah, the NG48 one I posted, for b18a/b

I should have some updated B18a bins up there soon with the new code.

Ok, double-checked everything this AM, it all looks right. Reburned ng48-PR4tune-19.bin, put new plugs in and still not starting.

If I pull a plug right after I try and start I can smell fuel on the plug.

Any more suggestions before I put the stock injectors back in and verify something else isnt wrong?

Well…it only takes three things to start a motor, spark, fuel and compression. You smell fuel, have you checked the other two?

Its alive! It was a bone-head non-related problem, the electrical connection to the starter was loose, seems like it gave enough juice to turn the starter but not to light up the coil. This is weird because I drove the car for a week since when we had the starter out. We must have bumped to connection while we were installing the injectors.

So its running and Xenocron, your basemap runs smooooth! I’m gonna try and tap the oil pan and bolt on the turbo tonight, yea!
