1994 ford f150 4wd 305 cu,in, truck, engine abruptly shuts down Sign In

Ford F150truck, v8, 305 cu. in. 4wd, 99000 mile.
Start & runs smoothly then it will begin to miss and it will abruptly shut down. By spraying carb cleaner or outboard winterizing fluid I can keep the engine running. Smooth run time before shut down varies.
What do you suggest?

You should monitor fuel pressure while the problem is occurring. This is a Ford 302 not a GM 305? Fuel pressure should be 30-45 psi with engine running . If you find that fuel pressure drops and the engine stalls, then you need to monitor fuel pump power and ground at the pump to determine if you have a fuel pump circuit issue or a pump issue.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

We had the same problem with a 95 the fuel pressure thought is first however it was at spec spent a lot of cash and time on fuel related parts and it was a coil under the distributor doesn't make since i know but thats exactly what ours did starting fluid and all

Please leave this alone as Ford didn't put a coil on distributor (as GM did) on anything of this vintage,

Doggyiam, if you had actually read his question you would have seen that he wasn't using starting fluid. Starting fluid (ether) will ignite with the slightest hint of a spark but carb cleaner will require a real spark to run.
