Ford Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
When you confirmed it is getting gas. Does that mean you verified good fuel pressure or there is fuel injector pulse occurring?
Will it start at full throttle?
Will it start briefly using starting fluid?
For a car to start it needs air, fuel, spark, compression.
You have ruled all of those out with your tests. So we are going to need to check them again. A vehicle that will not start on starting fluid means it has low compression or no spark. Are you sure your compression gauge is accurate and all plugs are getting good vibrant blue spark?
This is my 1st answer, but does not have to be my only answer. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. Please let me know if you are pleased by selecting a star rating above or by replying and saying your pleased. Not rating or rating 1-2 stars does not benefit you nor me in any way. Follow up and reply as often and when needed, there is no extra charge to do so.
Are you getting battery voltage to the coil?
Did you check spark from all plugs?
Fire once meaning it will start then immediately stall?
What is the fuel pressure?
At this point we will need to check
Battery voltage to the coil?
There are no other things to check at this time.
Here is a picture showing the test port.
Someone may have swapped to a newer year model fuel rail since yours does not match the Ford diagrams. So you will have to use fittings to T into the fuel rail to check the pressure or do so at the fuel filter.
The CEL going off indicates the CKP signal is getting to the PCM.
The fuel injectors will not pulse if the CMP sensor reading is bad.
Can you hold the throttle at wide open, crank the engine, and spray starting fluid direct into the throttle body. It has to start with spark and compression
The ignition coil is what I would replace next based on the starting fluid not even working which bypasses the fuel system components.
Hello again Chris here,
A coil resistance test is not accurate. A spark tester to verify the coil can produce 1/2 inch intense spark is more accurate.
This will tell you the strength of the spark https://www.amazon.com/AMPRO-T71240-Energy-Ignition-Tester/dp/B00A8FO87S/ref=sr_1_6?ie=UTF8&qid=1475087597&sr=8-6&keywords=ignition+spark+tester
A coil can be intermittent.
So far there is not much about your car failure that is normal. It should be running based on your replying info except on the spark appearing weak.
It depends how weak the spark is, which I can not see. Weak spark can result in no ignition of the combustion.
Compression we want to see 160-180. Minimum is 120
I see no reason to check the timing with those numbers.
