Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
Can you start with installing a fuel pressure gauge to the fuel rail service port and monitor the fuel pressure when it stalls. Normal pressure need to be right at 32 to 45 PSI. Check this for me and post back when you can and we can work from there. Im off today but will be here all day on Monday.
In most cases if the Engine runs fine with the MAF unplugged that usually means the MAF is bad. Are you sure its checking okay?
When it stalls are you able to tell if you actual loosing spark?
I would agree, in most cases if the coil fails it dose not come back. If unplugging the MAF allows it to stay running the you have to be Masking something. I have to wonder if the PCM is not at fault.
Unfortunately there is no test for a failing PCM beside replacing it with a known good unit. The 1995 is a plug and play unit with no programming needed , Have you tried locating a used one?
It is just a bit but any 1994 5.8 PCM would still work to at least answer the question as to if its bad. If it is then you would want to stay with the CA emission PCM.
Okay, post back when you need me. Im here everyday.
