can i swap my ecu with alarm for a non alarm ecu and bypass the vtss on a 93 zj 5.2?
Here is what is happening.
Jeep has very hard time starting, and currently will not start.
Vehicle - 93 Jeep Grand Cherokee Laredo 4x4 5.2
replaced auto shutdown relay
redid battery connection and verified all grounds to the engine
grounded out security system inside driver door
Here is what I was able to do until yesterday to get vehicle to start, once running it runs great, but
getting it started is getting worse and worse to accomplish.
1. Turn on Key
2. let sit for approx 30 seconds - security light comes on in dash (even after grounding out system)
3. let sit for approx 1-2 minutes - auto shutdown relay clicks rapidly for 3-5 seconds
4. check engine light comes on
5. able to start engine on first turn of key, catches immediately and runs great
Now - never get the rapid clicking in the auto shutdown relay, engine will not catch, cranks but will not
catch and start.
this is why i am wanting to swap out ecu's.maybe even the vtss. and does anyone know where it is on a 93 zj?...the vtss and vtss relay that is i guess b y the glove compartment.
