Got fuel, spark, compression, timing, and grounds, but the car still won't start
I'm stumped.
The car is a 90 DX, it's been converted to MPFI/OBD1. I just swapped in my built engine, and now it won't start. I have fuel, spark, compression, cam timing is good, grounds are all connected but it just cranks and half-starts/sputters, etc. ECU doesn't throw any codes, and the wiring is good. I swapped the distributor off the old running engine onto this one, so I know it works as well. I'm stumped, so I must be missing something. Any thoughts? |

what engine is it? also triple check your timing. sounds like mine, just cranked and cranked and cranked until i noticed i fucked up on the timing :1

Just went out and triple checked timing, I even pulled off the pulley to make sure the woodruff key was still in. Cam timing is good, both marks line up right. |

so you switched to obd1 and the car wont start now?
if you have been cranking the piss out of the car with no start that plugs are fouled my good man I thought years ago that wasnt possible with a fuel injected car until my bro's 99 civic si was broken into and they jacked the apex vtec controller. He sputtered the thing home and good knows how many codes wired up a new controller. Nothing. Had fuel spark no codes. Changed the plugs. Car ran like a champ and I went winging a stock bottom end b16a to 9500 like a little school girl for fun |

No.1 injector had no power going to it, fixed that, still won't start. Plugs are out, going to swap in a new set in after I re-do the injector wiring. |

Just re-did injector wiring, still not starting. |
