American Motors: 88 amc eagle, digital voltmeter, amc eagle


Question
QUESTION: I saw the posting of the 88 amc eagle with stalling problems. I am having the same issue. Starts cold runs for a while, stalls. It doesn't matter if the engine is warm or not. If I hold the ignition switch forward till just before the starter engages it stays running. and all fuel and ignition parts have been replaced along with the actual switch under the dash linked to the keyed switch.

ANSWER: If it starts and runs cold, then stalls, it sounds like a carburetor problem. You need to find a mechanic that is familiar with your carburetor. It could be something as simple as adjusting the choke or float level.

QUESTION: the carb is fine. It is in the electrical componants somewhere and I am at a loss as to where to look next. As I stated it runs fine if I hold the ignition switch forward to where it shuts off everything but doesn't engage the starter.

ANSWER: When the ignition switch was replaced, was it properly adjusted? This is the switch on the steering column. There is a rod that connects it to the ignition key. The ignition switch on the base of the steering column has slots that allows it to move to be adjusted. Cut and paste this web site and turn to page 35; it tells you how the ignition switch should be adjusted.

QUESTION: Yes it is installed correctly thank you for making sure, however it was having the same problem prior to me replacing the switch, hence the reason I replaced it, thinking that would be the problem.. Still frustrated...LOL

Answer
Using a digital voltmeter, measure Voltage at the (+) side of the ignition coil with the key on. Then measure it while cranking, then while running. It should be around 12 Volts. If not, check for an open in that circuit to the ignition switch & igntion module.
The ignition module can also be a weak link in the Ford system.
