xj 90 Fire+Fuel - Start Idle problem
Hi,
I am quite desperate. -Fuel sytem OK (new pump (39 psi at rail), ballast OK, voltage OK) - Fire (OK, injector pulses) - KPS changed When I turn the ignition key to "Start" the engine start but WHEN it get back to "ON" the engine stall. Some says the ECU, CPS, some says the ignition key others the MAP. I am really confused. Any help would be very appreciated! Regards

Re: xj 90 Fire+Fuel - Start Idle problem
What the heck is a KPS? Have you also checked the ignition switch located towards the bottom of the steering column under the dash. It's possible that when you let off the key the switch is shutting the engine off instead of it stalling on you.

Re: xj 90 Fire+Fuel - Start Idle problem
AIC was a very good lead in fact but was not the main trouble.
It was a fusible link located on the starter relay (+ pin for giving ingnition voltage) that was not completely cut thus instead of giving 12V was giving 3V. Dammit. Cost me 400$ for finding that. Stupid me. Many thanks for trying to help though. I am sure this information (IAC, TB, fusible link and key) will help someone. P.S. KPS= Camshaft sensor aka stator
