I have a remote starter for my 2005 gmc canyon truck for about 3 yrs. There have been a few times recently that I press the start button and the truck cranks, fires once and then continues to crank crank and crank. Then I go and stop it. I try the key and it will not start the truck it will only crank. I go back about 5-10 min later and the truck starts. Any ideas?

Just above each spark plug.

I had the same problem with my 2000 GMC Safari two years ago....drove me CRAZY!

Sometimes it would start right up...other times it just would crank and not start.

It turned out to be a cracked coil....I found it by using a spray bottle with water in it, and "misting" the engine, at night....with the engine running. (On a night when it DID start!)

It took a while, but finally the hairline crack let in some water and the electrical short showed by a spark coming out of the coil.

I replaced the coil with a new one, and it has never "not started" since.

Evidently the coil cover gets brittle and develops small, hairline cracks due to heat from the engine.

Oh...by the way....I tested the coil it showed that it was fine!....but it took the "misting" at night...in the dark...to find the spark "leaking" out.

it's probably the transmission and u might have to change ur fuel pump also

SOURCE: !995 Audi a6 Quattro only cranks wont start.

dealer only ,factory immobiliser is cutting in, try the spare key and if it doesnt start call the breakdown truck to take it to dealer

SOURCE: 235k miles. cut off one time going down road,

I have seen crank sensors go and leave no codes, but, likely the fuel pump is going away...they get hot and seize, then cool down and work again. I would not replace either without proper testing only because parts are expensive and there are other heat sensitive components in there. (coil etc) Be aware that it will check out good if it is running right while tests are being done.

Testimonial: "It cranks when hot and has sit for a while, when it would not crank. If you now think it might be crank sensor, how do how do I get to it. "
