Hi new to the forum,I have a 93 & 94 cavalier both 4 cyl i have transfered all the wiring from the 93 & put it in the 94 with the comp because it changes from 2 plugs in 93 to 3 plugs in 94. My problem is that it cranks but will not start I checked that the fuel pump is activating n it does I have power throughout the car lights radio dash turns on but im not getting current to the spark plugs from the icm can it be that its not working or is it that the comp does not work or even a groundwire how can i test or if there is something else that i have overlooked. Will be waiting for response going crazy without my ride...THANK YOU IN ADVANCE!!!!!

 

Not sure but what are you referring to when you say comp? When you go from 2 plugs to 3 plugs and leave something disconnected, look there first. What was left disconnected?

 

I think "comp" is computer. You need a manual for the electrical, especially that connector that is 3 instead of 2 connections.

 

sorry comp is the ecm if im correct (the Computer under the dash) in the 94 it has 3 plugs in the 93 it has 2 plugs now i changed all the electrical wires from the engine side and under the dash with the ecm so the wires & plugs are compatible no plugs left disconnected have power throughout the car but no power from the icm to the sparkplugs THANK YOU AGAIN IN ADVANCE.

 

You should figure out the plug connections from 2-3, are they compatible with what should be connected?

 

Yes they are,all plugs are where they should be map sensor fuel injection crankshaft ......ect.
