The remote dose not work could it be that the system is armed? How do i disarm it.

SOURCE: 2004 Jeep Grand Cherokee. Keeps stalling, engine

P0505 means the whole Idle Control system, not only the IAM. Check all related sensors (i.e. crankshaft sensor). Check with a voltmeter direct at the connector of the IAM if you get any signal. Remove the IAM from the TB, connect him, let someone switch your ignition key to ON. The IAM need to drive in/out for a short time to find the right position. Hold the IAM near a hard part, that they cant drive out completely! If IAM works fine, check the fuel pressure, check and clean your TB ( if not done yet). If that doesn't work, come back again please

I have a 93 jeep grand cherokee. it will only start when the check engine light comes on. i have replaced the ecm. still not fixed. any suggestions?


Did you replace it with a re-manufactured or used ecm? If used, not all ecms are compatible with every vehicle. It has to be the exact same numbers on the ecm, matching the one in your jeep.

New starter goodfuses,relaysbattery still no start


Check fuel pump 1st, should here it hum for a few seconds when you turn the key to ON (not starting). A bad crankshaft position sensor will cause a no start, yours may have a camshaft sensor as well. ECM needs both to run engine. Does the CEL come on for a few seconds like the other warning lights when you turn the key to ON? If not ECM is dead, shorted out or ground/power is gone to it. Check each spark plug and the wires. If spark is ok on for each plug, fuel pump comes on, I would look at the injectors but usually you get a stall as one goes bad. If those are ok then replace the crankshaft sensor but keep in mind the ECM might be fried.

1999 Jeep Grand Cherokee stalls immediately after


check intake manifold air temp sensor and engine coolant sensor...one may be out of range but not enough to turn on dash light. tests and specs can be found in chiltons or haynes, test is done with digital multi-meter.

ECM plug


it sounds like you have already located the problem, now you need to do something about it. Likely, by being partially unplugged, moisture and other bad stuff has gotten into the ecm connector. You need to carefully inspect all prongs and prong receivers for oxidation, dirt and burning. Make sure there is no problem with wires themselves where they are attached to the prongs. Once clean and securely plugged in you should be fine.

1999 Jeep Grand Cherokee stalling and not starting


Since you've replaced many of the usual suspects (fuel pump etc.) you might want to look into testing or simply replacing the crankshaft position sensor or the camshaft position sensor. If you intermittently lose one the these signals it would cause the problem you describe.
