8 people looked and no help come one guys

 

did you make sure the firing order is correct? make sure you dizzy is timed and sitting exacly where it needs to be

 

yes and yes but do you think since the motor is obd1 should i use my obd0 dizzy?

 

you should be using the obd1 dizzy

 

ok i got it started now everytime i hit the gas it dies and i cant get it to idel right

hello

 

 

Can anyone help me at all plz

 

bumpppppppppppppppp

 

few things might come into play here, you do need to use your old obd0 dizzy, with your original ecu, also did you use your original intake manifold? or the obd1 one? becuase of the injectors if you use obd1 you have to get rid of the resistor box, back to the dizzy using obd0 it will be of timing pretty bad severly retarded so you will have to cut out some of thhe adjuster (front side as you face the car with the dizzy installed) so you can advance the timing to normal, of coarse i dont mean cut it on the motor, just get an idea of were to cut it, the best way is timing light, no bolts in the dizzy get the light on its mark (not tdc) the three after that then when its there look at the dizzy and see were it has to be.

 

So..... in order to help you with this issue I will assume you need to do a few things. Just ignore any steps in the list if you have already done so.

1. be sure you are using your OBD0 distributor if you are running your OBD0 ECU.

2. OBD1 cams have a slightly different distributor slot index. It is slight, but it is definitely different. (dohc B-series OBD1 motors will throw a code 8)

3. Install your original OBD0 intake manifold with your original injectors.

4. Check your firing order

5. Check your timing belt to see if it is not off a tooth.

6. Reset your timing (assuming #5 checked out ok)


This should get you started assuming you are staying with stock ECU, injectors, and distributor.

 

see i have an obd1 conversion harnes and i have the whole motor that was in his hatch in my car now so im trying what that guy said about the dizzy trying cuting it to retard the timing a little i have his ecu in and his dizzy so its like an obd1 stetup his injectors and everything

 

O2 sensor as well? You also need a 4 wire O2 sensor if your OBD1

 

yeah but i took his o2 and its only a 1 wire...

 

do you have a cel? if so what are the codes? make sure that you dont have the map sensor and tps sensor plugs switched it could be a few things just need to know alittle more info

 

yea obd1 covertion will need 4 wire o2 most definatly, also obd1 distributor dont cut that one though, yea also good idea on checking your connections i know for a fact that you dont hook up the right plug or forget to hook up the idle valve it will buck on take off and bog act funny ect... hope it turns up soon.

 

i do have a check engin light but i do not know how to check it my buddy tryed cheking it and he could get it to light up or blink or what ever i dont understand itbut hot am i to run a 4 wire into my 1 wire o2 ill try it i mean why not

 

can anyone help me with that

 

You can read the whole instruction set but I find the last page most informative. It should help you hook up your O2 sensor. It will at least tell you the oem color of the wire & the function. If you have a jumper harness it should have wires for the O2 sensor. Of course only way to figure out the wires on the jumper is to trace it to the ECU, possibly go off of the wires from the harness, or find out who made the jumper harness and call them up.

what a moron....forgot the most important part:

there should be a 2 pin harness down in the right kick panel area, just loop it with a wire, early model have it in the drivers side by the shock tower under the hood, that should make your mil light blink the codes

 

should i turn the car on or should i turn it onto the on position
