I'm helping a friend out with his 10AE.
He just finished doing a haltech install and was waiting for me to show up with my wideband to do some baseline tuning. All of hte sudden the tachometer stopped working. It had worked before after the haltech install. We checked resistance of the coils/igniter to be 0.08 ohms. Then we checked the yellow blue wire that gives the tach in the car the signal. The wire was fine, we checked 12V to the coil from the tan wires, and each wire that the haltech is spliced in to control the coil, all checks fine. We even took the trailing coil/igniter from my 89TII and tried it on his car. We have nailed it down to it not sparking. We pulled the plug on my 89TII and cranked the car over and there was a very strong spark on my car. We then pulled the trailing plug on my friend's 10AE and there was no spark when it turned over. Any suggestions? My friend IAN and I are stumped. |
did you try his coil in your car? you need to see if its the coil pack or something else
|
my car was doing that. i tried a new coil but it didnt help. the check engine light would come on and the tach would go off, the codes said that there was a ground problem. when the tach would go off the trailing, i think, would also stop working. anyways the prob turned out to be a stripped tranny bolt that was grounding out. so something is grounding out somewhere

I had this problem as well as a another forum member. Neither he nor I were able to source the actual problem, but I am pretty sure its a ground issue. I cleaned up my grounds and added a bunch and the problem went away.

I'll remember to do that when i swing by to help him out again. I will also check for grounding issues as well. Thanks for the suggestions |

unfortunately i did not try his coil in my car. We only tried my coil in his.

these are the settings on the haltech... i'm not too familar with it since i've never used one before...
Spark Mode: Distributor Engine Type: Rotary Output Type: Constant Charge 5ms; Falling. I know for certain that the trailing plugs are not firing when turning over the engine with the fuel pump off. |

Did you flood the car? My tach and speedo never works after I flood it, and I have to turn it off and back on for it to work properly..
