Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello is this a 4.0 SOHC engine? Does the red theft lamp flash when you turn the key to on? No codes stored or you had codes that prompted you to replace the parts. Will it run if you hold the throttle part throttle?
Ok and fuel pressure is good and doesnt leak down? How many miles on the engine?
Hello, it says you are requesting a phone call but having issues on your end, we dont have to do one. Im just looking to see if the engine has a lot of miles and this problem happened while driving or you just came out and started having issues or after a recent repair./
Ok, does the engine sound like it cranks over normal or does it seem to hiccup or be a little slower? Did the vehicle die while driiving?
And when it dies it restarts every time so its hard to see if you got fuel injector pulse and spark besides fuel pressure?
Will it run with the maf unplugged?
And it will stop stalling with the maf unplugged and have power?
A vacuum leak would be the main thing that comes to mind, if you block off the pcv valve or brake booster vacuum line will it run
Yes im on most everyday im on pacific time so its only 630 here
Very good, soon as I see you post ill respond
Ok you can check for injector pulse
Spray carb cleaner into the intake see if it still runs
Very good. also check fuel quality too, take a sample at the rail or the filter
The eec power relay engerizes the fuel pump relay and the pcm supplies the ground to the fuel pump relay with an rpm signal from the crankshaft position sensor, when you turn the key to on it primes the pump,so when it doesnt run make sure you have rpm and injector pulse
Just power and ground, vref voltage. communciation with a scan tool and inputs key on engine off test
monitor rpm signal when cranking and stalls while cranking should be a couple hundred rpm steady signal. CKP sensor can fail from coolant leak or go bad over time on right side of engine by crank pully or the crank pulley is seperated and not reading correctly
Ok and you can unplug the coil and see if they injector continue to fire normally
Even though the TPS is new, make sure it is reading around one volt closed throtlle and not giving a false reading of wide open throttle which will disable the fuel injectors.
very good, let me know when you can
You dont have to reply back t me until you need more help. Im just replying right now so it takes your question off need for a respnse
Ok will the engine continue to run if you hold the throttle part way down? No codes now?
Ok the code says bank one the passenger side is running lean, what cylinder injector did you replace and how did you know it was bad, was it not firing or leaking down fuel ?
Running out of things to check here, what is the fuel quality like,Also have you tried dropping the exhaust to see if you have a restriction
Then im out of ideas as to what to check since it starts, stalls and fires right back up so I will opt out and open this question to see if another expert can assist you
