im thinkin it has to be the dizzy but wut about my iacv???and i also have a check light!!!!!cant have that.any help?????????

 

Well saying you have a CEL without giving us a code is just a waste of binary code Read the code, come back.

 

ef hb...converted over to obd1...no plug to check codes...and need obd0 ecu to check codes the original obd0 way...none of my obd0 ecus are blinking.if i was getting a code i would have taken care of it already.so i guess im stuck for now.any help without code info will b great...thanks

 

Why do you need a plug to check codes? Did you remove the service connector?

 

ef hb dont have the plug to check codes.plus im conveted to obd1 so i use a pinout on the ecu to check.

 

You will have that plug, how do I know? Because I have one, my friends have one, pretty much all the cool kids have the plug. How else could you have properly set timing for all those years? You do know you jump the service connector before you whip out the timing light. Jumping the ECU works as well, it's just tedious and I hate extra work like that

 

im not throwing any codes.my hb is dpfi-mpfi.converted to obd1.i cant get my car to start!!Plenty of fuel but no spark.could it be my wiring to c1/c2..my crank sensors from the dizzy???help?
