hard to start & will cut off after it starts. seem like fan is coming on then off as it idles. what to do next?
Asked by Gewalker74 Feb 27, 2013 at 08:48 AM about the 1993 Buick Roadmaster 4 Dr Limited Sedan
Question type: Maintenance & Repair
I've change plugs, wires, dist cap, rotor, fuel filter, idle cont valve, pcv, coolant temp sensor, & map
sensor. I clean carb, egr valve, & mass air flow sensor. Only code was 15, that's why I replace
coolant temp sensor. It started but cut right back off. I spray starter fuild in an it will start, I can
drive then stalls out. But will start right back up without spraying starter fuild in. Its getting spark
from icm and fuel pressure seems to be fine. It has 102,678mi on it. Everything original except what
I've changed. Will new timing chain solve problem?

Have you checked your fuel pump pressure? The pump may be weak. thus letting start but not idle.

Im still at a lost. I replaced fuel pump. Still won't start. So I replaced spark plugs again, same result. Could the carburator be bad? Or is the timing off?
DanR63 answered 2 months ago
Still sounds like a no fuel situation. Try checking the injectors/throttle body unit. If you are sprying fluid in and the car runs unitl it runs out the car is starving for fuel.

Change injectors/throttle body. Still won't start up. It almost started but no dice. Could the timing chain be a factor?
