Engine died while driving, no spark, replaced coil, now starts, idles, runs well at low rpm, but misfires when accelerating. No check engine costs thrown. What should I check next.

Change your ignition module. The distributor is a weak point of the Honda, I will always change out the whole thing than just try the coil.

Just started spitting and sputtering out of the blue. mainly when accelerating or up hill no check engine light on so no code. plugs or coil where to start

What grade of fuel are you running in it?? If you put 89 or 93, that will sometimes cause it. maybe all new plugs could help. Problem is usually (in my own experience which is with my own that I owned from 2000 to 2012 and my sisters expedition 2001 for several years) that you are getting sufficient spark for the computer to think all is well, but not enough to ignite a higher octane (or ethanol) gasoline. It takes more compression than it does to reliably run 85-87 octane. I will probably get abused over this suggestion but go read up on gasoline. These engines are not designed for running high octane or for that matter high ethanol fuel. Ethanol is just a form of alcohol, and it burns cooler and takes greater compression and or more spark to ignite it. I would change all of the plugs to start, they may just be getting weak. But No matter what seemingly more qualified mechanics tell you, don't run high octane gas in your expedition, it will get you smacked broadside in an intersection. I didn't get hit but came close on several occasions before I figured out the issue. Another issue could be the left rear coil, sometimes your heater core line may leak and drip on the coil and could ruin it. Oh, and I wish you the best of luck changing that plug. It ain't fun. One last thing, go read up on fuel grades and octane levels and educate yourself, gas stations like selling more expensive fuel , but if your ride says run 87 octane, that is likely what it needs or vice versa (run 93) in the case of these newer high performance four and six cylinders with turbos.

Ford 1981 f 150 not running changed Coil distributor cap Roar arm plug wires did not help started bur ran extremely rough then died

motors need 3 things to run properly. gas spark and compression. the starting point. also spark timing.
the motor you are dealing with is easy. i just rebult a 1978. anyways sounds like a timing problem . first i would check the distributer. if all is ok spay a squirt of starting fluid in the air filter, or even wd40.,,,,,,,see if it is gasoline problem. isolate where the problem is.

Truck will not start after filling with gas.wait a few minutes it cranks and runs fine.any suggestions?

Which brand? What kind of gasoline? Some cars doesn't run with all gasoline grades also there is some gas station with poor quality of gasoline.
Happened to my car too, I always use SHELL but one day I stop in the MOBIIL gas station to put some gas, got home and the next day the car won't start had to by the STP aditive to put in the gas tank. wait about 10 minutes and car starts fine.
Another thing is my car won't run good with all gasoline grades
I always use the regular one.

My 2004 Nissan Quest ignition coils keeps going bad?

Each coil has three wires. The black wire is a dedicated ground. The Red wire is a dedicated power supply. The remaining wire is the control wire from the computer.

There should always be ground no matter what.

There should always be power with the engine cranking or running.

The control wire is best looked at with a lab scope. You should see a square wave when the computer fires the coil.

Out of curiosity what brand of plugs do you have installed in the vehicle?

Car stop running just cut off.could it be the starter.

No the starter has nothing to do with your car staying running you should check fuel issues fuel pump injectors regulators. Also most likely check ignition components spark plugs spark plug wires distributor cap and rotor or coil if equipped either or and check coil pick up sits underneth coil packs i would go to advanced auto parts and they can check coil pick up and coils or you can by pulling out spark plug and putting it back in wire set spark plug next to engine block if you see blue spark coil is good if orange bad not hot enough to ignite gasoline. is your check engine light on if so get codes read for free at autozone or advanced auto could also be crankshaft postion sensor or camshaft postion sensor lmk if it helps. if it helps please leave 4 star reviw and good comment thanks

Doesn't start

I assume that when you started the car the starter was running and the engine was cranking.
Remove the #1 boot from spark plug 1. Insert a screw driver to the booth, bring the screw driver near the engine body (about 2 mm) and let someone start the engine. If there's no spark, replace the ignition coil. If there's a spark, check the ignition timing with a strobe light.

Before changing the ignition coil, make sure that the wires connected to it are alright. Remove them from the coil and switch on the engine. Measure the DC volts from the wires. You should get a 12 volts reading between them.
