A little while back, I converted the 13B in the Jensenator from an S5 ECU to an S4, so I could get rid of the electronic oil metering pump which will put the ECU into 'limp mode'. Once done, I had no injector pulse. I went over every connection and wire color code at least 5 times, no luck. I haven't had much time to mess with it until today and I yanked the whole harness, opened it up and traced.

All the wire connections were perfect- except one. The S5 and S4 FI setups use the same crank angle sensor, but the wiring is flipped from S4 to S5. It took a lot of head scratching and perusing of wiring diagrams to find this, but it now has injector pulse! Now all I have to do is put the harness back in and fire it back up. Hope this helps someone else.

 

Finally got it all back together, it fired right up.
