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

 

D16A6.

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.

 

a d16a6 huh. obd1? why is it obd1 may i ask. i kept mine obd with a pm6 ecu. what ecu are you using?

 

Re-wired the whole car to OBD1 because I like it better. Using a P06.

 

so you switched to obd1 and the car wont start now?



if you have been cranking the **** 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

 

Nope, car was OBD1 before this all began. All I did was swap the engine for a fresh one.

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.

 

wow the whole car re-wired to obd1! i left mine obd and i just got my hands on a p06 with my d16y7 i got. i also got a conversion harness though im not sure if its from obd0 ---> obd1, but what i do know is it has a broken pin which should be able to be fixed. but damn obd1, not worth my time.......

 

Ok, not the whole car but the ECU plugs were swapped out for OBD1.

Just re-did injector wiring, still not starting.

 

firing order?
