Miatas hate me
Ok howdy:fawk:
I recently rebuild my engine in my 99 with a donor block off an older miata It ran before i pulled it in and now she dosn't want to start. Its getting spark, getting fuel, compression (around 150 in all cylinders), and i checked timing about 5 times, its dead on. It backfires and hickups but dosn't want to start. https://www.youtube.com/watch?v=me2g...ature=youtu.be i reused the oil pump, so i had to grind the nub and drill and tap a hole for the crank sensor. 99 crank position sensor mount differences - Spec Miata Garage - Mazda Racers if im reading this thread right its saying to use an adjustable cam wheel so i can set my timing because the hole is a little different locations then the newer style oil pumps? any advice would be awsome im really stumped:bowrofl::bowrofl::bowrofl::bowrofl::bowrof l::bowrofl: |
perhaps a bad starter??

Stock ECU/MAF/injectors/ect? Same BP4W head as before, correct?
|
I'm guessing your plug order or injector wiring is incorrect.

did you set your timing correctly? |
Timing is set, i had another person verify this
It cranks good with a charger on it, i don't think a starter would cause backfire Didn't touch the injector harness, only rebuild the bottom end The wires are in the right firing order, i also changed the wires Exact same setup, just rebuild the bottom end. Same everything timing is off somehow? https://sites.google.com/site/miatad...ensor-on-crank This post says "the tooth that indicates CYL1 is actually 10degBTDC making it possible to set base timing using a scope." There are 4 teeth on the crank sensor wheel, which tooth represents cyl #1? Thanks for all the replies, somebody does love me |
edit: my plan is to line the sensor up with whatever tooth represents cylinder #1, 10 degrees before tdc, and set the cams 10 degrees before top dead center and my timing should be set to the new location of my sensor.

Coil pack or plugs backwards
|
Is it possible i put the crank position tooth wheel on wrong. A tooth is alittle less then a 1/4 turn on my crank away from my sensor top dead center.

lol i didn't cheak up on this thread until now to follow up, and i fixed the problem. Crank trigger wheel was on backwards. Thanks pdexta but i got to it first haha. First startup was great. First time driving a miata also. Gotta say its a sweet ride!
