I just built an obd1 Poor man type r, now i have fuel and i have Spark, but Cylender 1 and 2 are not firering. I changed the Injector, it still doing the same., My next thing is to change the ECU, and if not check the Distributor. What ya think? Any help would be appreciated, thanks.

 

someone please help

 

start with the cheapest and easiest, cap and rotor, spark plugs, plug wires, ignition coil, etc. then move on to the ecu if its still not fixed

 

Don't just thorw parts at it, that is what make it expensive.

Find out if you have spark at those two cylinders...
Find out if you have injector pulse to those two cylinders... Used a niod light set or a test light.

If you have both of the above, recheck your plug wires/ are they on right? Double check.

 

spark plugs are new and so is the wires, so ill try the next ecu, my buddies ecu. If that dont work, ill go into the ignition, a nd pretty much what ya posted it, thank you. Also compression test was done and is good, thank god.

 

Don't take this offensively, but are you sure you have your spark wires in the right order?
It should be 1-3-4-2

 

i just check it. Its good. Im waiting for my freinds ECU, and then im changing the Distrobutor, If anybody has anymore ideas Please let me know and thank you for your replys

 

yes i have spark on both cylinders, and i changed the injectors, wires are in order.

 

flaco1978:::: sometimes if u put the distribtor on wrong it will do dat cuz iv done that befor

 

i just took it off and place in just to double check and nothing, it was good. thank you eveyrone, anymore suggestions.

 

u pulled it out and spin the teeth around then put it back. what did it do when u cranked it cuz it it changes the tyming dat will too trow clinders off

 

no i didn't do that, but ill go ahead and try it. ill let you know

 

well try it.. it couldnt hurt goodluck and make sure ur tdc is lined up rite and like vegas in said check ur firing oder

 

the firing order is good, TDC is good, i have already checked the the ECU, its not it, now im going into the distributor. Im using my buddies tomorrow. hopefully thats it. Thank ya so much for ya help. If anyone has any more ideas, they are very welcome. thank ya again

 

If you get spark and fuel then by default it should fire. Fuel + source of ignition= fire. You arent getting one or the other to those cylinders. I would check the distributor.

 

Bingo! That was it...... Problem fixed. Thank ya so much for everyones Help.
