No CEL or spark
Hey guys and gals. working on a customer's car and after the 5mt swap amongst other things, the car will not start now. I get no CEL when I turn the key to the on position and it will crank all day but no spark... I have checked mostly everything I can think of but it us just odd. If you can think of anything please make suggestions

Tom,
On checking the wiring diagram with the transmission change in mind. ----There is a black ground wire which runs from a ground point in the original transmission, to the inhibitor switch which normally grounds two circuits from the ECU. Could you have overlooked this connection? My only suggestion at this stage, Trevor. ![]()

Has the car got a bugular alarm some times they cause problems?

I have never had this issue before, mind leading me in the directions of this?

If you didn't miss that ground that Trevor mentioned, i'd definately see if there's a security system installed. Burgalar Alarm, I haven't heard that in awhile
![]() If there is an alarm, some of those have an ignition interrupt. Random thoughts from a random mind.

Most burgalar alarms have one of two modes of operation, cut the power to the starter so you can't get the starter to turn over and the second is to cut the power to the igination. The first thing to check Tom is if the alarm has a switch on the key ring. If the car has central locking doors and it didn't come standard then I bet its the problem. My 1992 had that type of system and it also us to flatten the car battery.

That sounds to me like the ECU isn't getting power, check your fuses with a test light.

I am checking all the power inputs to the ECU and the available grounds. Anyone that can use a test light, check to see if plug B60 pin 12 is a ground or a 12v+ right now I am not sure and I need to keep checking the wire schematics and pin voltage charts

i am printing out the other page of the pin-outs and I am thinking maybe the ignition switch isn't sending power to the ECU... Gotta head over to the shop to check... if anyone comes up with something I may be missing please call me at (609) 276 7279

I've been on and off the phone with Tom for the past few hours. He found part of the problem, the "Check Engine" bulb has been removed by someone
![]() He has a bulb in, and now it lights when he starts it like it should, but it doesn't come on after and when he checks codes, it just gives the constant blinking "no codes". So, now at least he is past the ECU part of the equation, he has also spoken with the tech that installed the alarm and has ruled that out. It's still cranking, not starting because there is no spark, and not showing any codes... What else??? He forgot to take his laptop, his numbers up there^^^^

It's a single black wire - one end connects to a bolt on the firewall directly below the dogbone. Halfway up the wire is a plastic connector that just butt connects it together. The other half of the wire bolts to the tranny at the dogbone. I know it sounds odd for one ground wire to be the culprit, but it stopped mine from firing up when I changed my tranny out.

Ok, after getting rid of the jerry-rigged alarm system, I finally have spark again. I also have fuel.... but still no start

the alarm wiring sounds consistent for the car you're working on
