Long cranking to start

[demartin]

Here is the latest scoop....they claim that I have MAP sensor reading that indicates loss of fuel pressure.

Recommended course: new fuel injectors and an expensive valve adjustment. (Valves are not closing properly)

Any reaction to this?

Injectors makles soem sense, but valve adjustmnet does not.
(Maybe someone mentioned teh injectors (valves) not closing and someone misunderstood?)

You never get all the injectors failing at the same time as they are suggesting.
I don't think the shop has a clue what's wrong or how to fix.

If the valves have not been adjusted yet I would go ahead and have them done and see how it runs. You can always troubleshoot the fuel system later.

Demartin, thank you for substantiating my claims of a long cranking time with my Honda Pilot. I was beginning to think I was going crazy or something.

I took my vehicle to the shop on Monday for a state inspection and (thankfully) my repair facility was able to replicate the long cranking time to start. They suggested that I have a complete throttle body cleansing along with mixing an additive in my fuel tank. I am going back to the shop on Thursday to have the repairs done. Hopefully this will fix the problem.

Well, I got my Pilot worked on yesterday. The service center did a cleaning of the fuel injection system and the mechanic said it was pretty dirty. According to the bill, the cleaning includes: "connect injector cleaning system to vehicle fuel system. Check system operating pressure and fuel delivery. Perform injector cleaning procedure." While doing other maintenance on the vehicle, the mechanic also found that my coolant temperature sensor was bad.

Anyway, after all this work has been done and I am a bit lighter in the wallet it seems that the problem still exists! Even starting it up at the service center seemed to take just as long to crank as usual.

Any suggestions on what to do next?

I hate to tell those of you who have spent $$$ trying to figure this issue out but I have a brand new 2012 EXL and am having the same problem. Random times when it simply won't start and almost starts for about 5 to 7 seconds until it eventually starts. I have Googled the issue as well as YouTubed it and even brand new Pilot's (like mine) are having this issue. I'll be talking with my dealer this week and report back.

The saga continues . . .

I took my vehicle to another Honda dealer for a recall notice. While there, I explained the long cranking problems I've been experiencing. The service technician asked if I replaced the original spark plugs with spark plugs purchased at a Honda dealer and I told him "No". I did, however, buy the OEM specified brand of spark plugs which are NGK as specified in the owner's manual. He told me that NGK plugs that you buy at an auto parts store are not the same as Honda NGK spark plugs purchased at 3 times the cost at a Honda dealer.

I was very suspicious about this statement so I called NGK directly and they said that it is not true. An NGK spark plug that you buy at an auto parts store is EXACTLY the same as one purchased at a Honda dealership - assuming the spark plug part number is the same.

I guess it's back to the drawing board!

That tech was a wanker. I would have punched him in the dick. You should call his boss and let him know his tech is spreading lies. The NGK Laser Platinum plugs are the same as the ones that come in the Honda box for sure.

Either fuel or spark is missing and it shouldn't take a rocket scientist to figure out which. I've heard of some vehicles that have marginal crank sensor signals at low RPM's, which many ECU's use to allow plug coils to fire and also injectors to work. EDIT: in other words, the ECU probably wont deliver fuel and maybe not spark without sensing the engine is turning.

I assume they have measured rail pressure during crank?
